Executive SummaryThe first groundwater monitoring round for 2017 was conducted by AECOM between 15 - 17 May 2017 atPfizer Ireland Pharmaceuticals API plant (Pfizer Ringaskiddy), Ballintaggart, Ringaskiddy, Co. Cork. Themonitoring was completed in accordance with requirements of the site’s Industrial Emissions Licence (IEL)and is reported in accordance with Stage 1 – Stage 3 of the Environmental Protection Agency’s Guidance onthe Management of Contaminated Land and Groundwater at EPA Licensed Sites, July 2013.

Groundwater was sampled from the seven monitoring wells required in the IEL and analysed for the followingparameters:

· Volatile organic compounds (VOCs)

· Alcohols

· Dissolved heavy metals (arsenic, cadmium, chromium, copper, lead, nickel, zinc and mercury)

· Ammoniacal-nitrogen

· Major ions (chloride, potassium, sodium, nitrite, nitrate, phosphate, sulphate, nitrate, nitrite, magnesiumand calcium)

· Carbonate, bicarbonate and total alkalinity

· Ionic balance

In general, the groundwater flow pattern and long term declining solvent trends have remained consistent atPfizer Ringaskiddy for several years and can be summarised as follows:

· Groundwater flow direction in both the subsoil and bedrock aquifers is in an eastward direction acrossthe western portion of the site. Moving further east, groundwater in the bedrock aquifer is contained inan area north of the nature pond by groundwater abstraction from two containment wells, C1 and C2. Itis understood from historical data that under natural gradient conditions groundwater flow wasnorthward in this area towards Monkstown Creek.

· A general overall declining trend in solvent concentrations has been evident in groundwater from the IELmonitored wells at Pfizer Ringaskiddy since the mid-1990s.

· Solvent mass recovery, as a result of groundwater abstraction from wells C1 and C2 (and historicallyfrom other wells), has followed an overall trend of decreasing mass loads over time. This is attributed toa combination of engineering up-grades, removal of source contaminants and groundwater abstractionitself. Ongoing natural attenuation of dissolved solvent concentrations along the groundwater pathwaydown-gradient of the source area has also reduced the overall mass recovered.

Conclusions from Round 1 May 2017 monitoring round are:

· No floating/sinking non-aqueous phase liquid layer was detected in any of the monitoring wells dipped.

· Total VOC concentrations in May 2017 were generally stable compared to November 2016, increasingslightly in groundwater from three wells.

· The THF concentration increased in groundwater from well 501 between November 2016 and May2017, from below the MDL to 0.04mg/L. THF also increased in groundwater from well C1 betweenNovember 2016 and May 2017, from 0.011 mg/L in November 2016 to 0.14 mg/L in May 2017. The THFconcentration decreased in groundwater from well 404 (from 0.062 mg/L in November 2016 to0.052 mg/L in May 2017). THF remained below the MDL in groundwater from wells 7, 205, 409 and 702.

· Alcohols and acetone were below detection in groundwater from all seven IEL monitoring wells in May2017.

· Cyclohexane was detected in groundwater from one well, 501 (0.36 mg/L) in May 2017 decreasing froma concentration of 1.8 mg/L in November 2016. Cyclohexane remained below MDL in the remaining sixwells.

· In 2015, leaks were identified in two weak effluent manholes CS116 and CS124 located up-stream ofwell 501. Repairs to the manholes were completed in February 2016, with both manholes passingEN1610 pressure testing. Decreases in alcohol concentrations in both 2016 rounds and Round 1 2017are confirmation that repairs to the manholes have been successful.

· All licensed monitoring wells appeared to be in good condition during fieldwork and do not require repairor maintenance.

1. Introduction

1.1 Project Contractual Basis and Personnel Involved

AECOM Ireland Limited (AECOM) was engaged by Pfizer Ireland Pharmaceuticals (Pfizer Ringaskiddy) toconduct groundwater monitoring at their API plant, Ballintaggart, Ringaskiddy, Co. Cork (the site) in May2017. The work was undertaken in accordance with AECOM Proposal OPP-617344/CKRP0001, dated 31March 2017 and authorised by Pfizer under their purchase order number 8501496689.

The AECOM team for Round 1 May 2017 comprised the following:

· Project Director: Kevin Forde, Technical Director

· Project Manager: Edel O’Hannelly, Principal Hydrogeologist

· Data Assessment and Reporting: Brendan McCarthy, Environmental Scientist

· Field Scientists: , Brendan McCarthy and Dan O’Leary, Environmental Scientists

Laboratory analysis of samples was subcontracted to Exova Jones Environmental Limited, Deeside, U.K., anAECOM-approved laboratory with UKAS accreditation.

1.2 Background Information

The site is located in Ringaskiddy, Co. Cork. A site location map is presented in Figure 1.

Pfizer Ringaskiddy is a large, multipurpose manufacturer of new and existing active pharmaceuticalingredients and their intermediates. The plant in Ringaskiddy comprises three main production buildings,one active pharmaceutical ingredient milling plant: associated site utilities and storage facilities. A site plan ispresented in Figure 2.

The site operates under an Industrial Emissions Licence (IEL) issued by the Environmental ProtectionAgency (EPA), IEL number P0013-04 (originally issued as an IPC licence in May 1995).

Under Condition 6 and Schedule C.6 of the licence, biannual groundwater monitoring is required frommonitoring wells: 7, 205, 404, 409, 501, 702 and hydraulic containment well C1. Well 3 was originally part ofthe site’s groundwater monitoring requirements, but was decommissioned in 2007 with EPA approval.

1.2.1 Site History

The parcel of land which includes the current Pfizer Ringaskiddy facility was a greenfield site until 1969,when construction work on the Pfizer Ringaskiddy citric acid plant began. Pfizer Ringaskiddy began citricacid production at the site in 1971 (the citric acid plant was later sold to Archer Daniels Midlands (ADM) in1990 and continued operating until 2005).

Pharmaceutical production at Ringaskiddy commenced in 1972. Since then, there has been on-goingdevelopment of the plant, with the construction of new buildings and expansion of existing buildings, up-grading of facilities and addition of new facilities. Three major expansion projects, completed in 1984, 1994,and 2001, added significantly to pharmaceutical production capacity at the site.

Towards the end of 2007, Pfizer Ringaskiddy ceased manufacturing activities in Organic Synthesis Plant(OSP) 2, as part of a business rationalisation plan to eliminate excess production capacity. The physicalbuilding infrastructure has been retained and a section of it has been refurbished as the New ProductTechnology Laboratory, NPTL, which was officially opened in May 2014.

The former ADM facility was located immediately to the west of the Pfizer Ringaskiddy plant and wasdecommissioned and dismantled by Corrin MDA in 2006-2007. The IPPC licence for the ADM site (P0053-01, which was held by Corrin MDA) was surrendered in September 2007, following completion of the sitedecommissioning and a successful exit audit carried out by the EPA.

Pfizer (Pfizer Biotechnology Ireland, PBI) subsequently constructed a small scale biologics facility in theundeveloped western portion of the former ADM facility. The PBI facility was separate from the existing PfizerRingaskiddy site and operated under a separate IEL, P0864-01. In 2011; the PBI facility was sold to BioMarinManufacturing Ireland, now known as BioMarin International Limited.

1.2.2 Site Description and Setting

The Pfizer Ringaskiddy landholding comprises approximately 21 hectares on the southern shore ofMonkstown Creek in Cork Harbour, approximately 11 km southeast of Cork City, see Figure 1.

The site has a relatively steep topographic gradient, with ground on the western portion of the site (OSP 1) atapproximately 15 metres above Ordnance Datum (m OD) sloping towards Monkstown Creek and the greaterCork Harbour area (~400 – 500 m away) to the north and east.

Land use in the vicinity of the site is a mix of industrial and agricultural, as summarised below:

· North and East – Monkstown Creek (an inlet of Cork Harbour and a proposed national heritage area(pNHA)) and the greater Cork Harbour area (a designated special protection area (SPA)) are locatednorth and east of the site. Ringaskiddy Deep Water Terminal borders the site to the east, withRingaskiddy village some 800 m southeast of the site.

· South – The N28 national primary road runs east-west along the southern site boundary. IDA-ownedland, currently in agricultural use, is present to the south of the N28, with Janssen Biologics (formerlyCentocor) located 470 m to the south of the Pfizer OSP4 building and with the Novartis RingaskiddyLimited active pharmaceutical ingredient facility 750 m to the south.

· West – BioMarin International Limited, with the Raffeen Creek Sports Club lands (owned by Pfizer)further to the west. Shanbally village is located 750 m west of the site boundary.

1.2.3 Hydrology

The site is bounded to the north and east by an estuary known as Monkstown Creek, which is a tidal inletlocated on the western side of Cork Harbour. Coastal and estuarine water quality in Cork Harbour isclassified as ‘unpolluted’ by the EPA1.

There are no other surface water features in the vicinity of the site.

1.2.4 Bedrock Geology and Subsoils

Geological Survey of Ireland (GSI) data2 indicate that the bedrock geology underlying the site consists ofWaulsortian Limestone. This massive, fine grained, unbedded limestone is Carboniferous in age3. Two majorfault lines traverse the site, the first runs almost parallel with the site’s southern boundary and the second, inthe eastern section of the site, runs in a north to south orientation.

Older Carboniferous marine interbedded grey/brown sandstone, siltstone and mudstones, referred to as theCuskinny Formation of the Kinsale Group (Lower Carboniferous age), occur to the south of the southernfault.

According to the GSI, subsoil consists of made ground across the majority of the site with bedrockoutcropping in places. Previous AECOM field studies have identified two separate geological units beneaththe Pfizer Ringaskiddy site, which include relatively low permeability subsoil deposits (comprising of soft,grey to greenish brown silts, with some fine sand and gravel) overlying Carboniferous Limestone.

Subsoil thickness varies considerably across the site, with a thickness east of OSP1 of 4.3 m and increasingto 11.8 m north of the wastewater treatment plant. These silty subsoils thicken in an inferred infilled glacialchannel (roughly co-incident with the mapped north-south fault line), in the area north of the nature pond.

AECOM11

Eastward from this point the subsoils decrease in thickness again until limestone bedrock outcrops on thesite’s eastern boundary.

Pale grey to bluish grey, fine grained, crystalline limestone, often weathered to varying depths, lies beneaththe subsoils. This fractured rock is considered to have a relatively high hydraulic conductivity. Geologicallogging of the bedrock4 indicated the limestone aquifer is complex, with a characteristic upper-weatheredzone, the lower horizons of which are brecciated or fractured to the point of being gravelly in nature, and withthree distinct joint orientations (one vertical). The bedrock porosity was found to be between 1% and 3%,with weathered bedrock porosity estimated to be an average value of 15% (estimations due to variability ofweathered limestone).

Depths to the top of competent bedrock range between 3.3 m (east of the containment wells) and 16.7 m bgl(north of the containment wells).

1.2.5 Hydrogeology

According to the GSI website, the bedrock aquifer beneath the site is classified as a “Locally importantaquifer – karstified (Lk)”. Due to the fractured nature of bedrock beneath the Pfizer Ringaskiddy siteidentified in previous investigations, the aquifer is considered to be relatively productive in this area. TheGSI’s classification of vulnerability of the underlying aquifer is ‘High’ to ‘Extreme’ vulnerability, with bedrocklocally exposed at the surface.

1.2.6 Groundwater Flow

Hydrogeological conditions at the site (groundwater flow direction, dilution, and degradation of contaminants)have been examined by AECOM in several investigations since 1993. A summary of the early investigationsis presented in an AECOM quantitative risk assessment report from 20065.

General depths to groundwater range from 4 m to 10 m below casing top (m bct) across the site.

Ultimately, groundwater in the limestone is interpreted to flow in an easterly direction under normalgroundwater conditions (natural gradient). However, when this flow reaches the glacial channel in theeastern portion of the site, it swings northward to discharge to Monkstown Creek on the site’s northernboundary.

A hydraulic containment system has been in operation since February 1996, comprising two activeabstraction wells, C1 and C2. This system alters natural gradient conditions and contains groundwater withinan area north of the nature pond (see Figure 2) and is designed to prevent groundwater with lowconcentrations of volatile organic compounds from reaching the northern site boundary.

In previous site investigations, an upward hydraulic gradient was identified between the subsoil and bedrockaquifers, suggesting groundwater confined in the bedrock aquifer is being forced up into the subsoils above.

1.2.7 Groundwater Redox Chemistry

Previous field measurements of low redox potential and relatively high concentrations of dissolvedmanganese and iron, together with low to non-detectable nitrate concentrations, indicate strongly reducinggroundwater conditions beneath the site.

While health and safety procedures on site currently prevent the field measurement of dissolved oxygen andredox potential (water quality meter is not intrinsically safe), the low nitrate concentrations reported in manywells indicate that redox conditions in groundwater remain reducing. In addition, hydrogen sulphide odourswere noted from groundwater from one of the seven wells, which is also an indication of reducing conditions.

1.2.8 Chemicals of Potential Concern in Groundwater

Groundwater monitoring data is available for the Ringaskiddy site dating back over twenty years (to 1994/5).Historically, volatile organic compounds (VOCs) have been detected in groundwater from the site, mostnotably: BTEX hydrocarbons (benzene, toluene, ethylbenzene and xylene), alcohols and tetrahydrofuran(THF). Alcohol detections are intermittent, but for the most part undetected in recent years; while BTEX andTHF tend to persist, though with long-term decreasing concentration trends being apparent.

In 1996, a hydraulic containment system was installed (wells C1 and C2) to reduce the mass of dissolvedphase VOCs migrating off-site via groundwater flow toward Cork Harbour. Since 1996 groundwater hasbeen abstracted from wells C1 and C2 on a continuous basis and treated in the site Waste Water TreatmentPlant. The mass of solvent recovered through operation of the hydraulic containment system is estimatedfrom pumping rates and analytical data from biannual monitoring. Assessment of containment systemefficiency and the need for rehabilitation works is incorporated in biannual monitoring reports.

In 1998, following two solvent loss incidents relating to underground storage tanks (USTs), the down-gradienthydraulic containment system was augmented by the installation of free-phase product recovery wells R1,R3 and R4 in the underground storage tank (UST) source areas. Pumping from the R-series wells ceased in1998/1999 in advance of removal of the northern and southern UST tank farms.

Following UST removal from the solvent recovery area, additional recovery wells, RC1-RC6, were installed inthe former southern UST tank farm footprint in 2000. Pumping from the RC wells ceased in May 2005 andthe RC-series were decommissioned in May 2007 with EPA consent.

Since the hydraulic containment system was commissioned, dissolved phase concentrations of BTEX andTHF have reduced. Between 2009 and 2011, methyl tert butyl ether (MTBE) concentrations peaked down-gradient of the solvent recovery area and subsequently declined (data available up to November 2016).

Most of the chemicals used on site are prone to degradation under aerobic and, in many cases, anaerobicconditions. The main exception is THF, which has been found to be relatively persistent in groundwatersamples collected from on-site monitoring wells, compared to the other volatile chemicals used on site.

1.2.10 Monitoring Network

Over many years of site investigation, Pfizer Ringaskiddy has installed a large number of monitoring wells onthe site. Monitoring wells are screened at various depths, with the majority of wells installed in the bedrockaquifer. Known construction details for the IEL monitoring wells are summarised in Table 2.

Under the terms of Condition 6 and Schedule C.6 of the site’s IEL (P0013-04), Pfizer Ringaskiddy is requiredto undertake biannual groundwater monitoring from eight groundwater wells installed on site (monitoringwells: 3, 7, 205, 404, 409, 501, 702 and hydraulic containment well C1). However, well 3 wasdecommissioned in 2007, with EPA approval.

1.3 Project Objectives

The objectives of groundwater monitoring for Round 1 2017 are as follows:

· To sample groundwater from seven wells and analyse for the parameters required by the site’s IEL

· To assess the direction of groundwater flow

· To assess changes in contaminant concentration trends over time

1.4 Scope of Works

For the Round 1 2017 groundwater monitoring round, the following scope of work was completed:

· Measurement of depths to groundwater and total well depths in all accessible monitoring wells acrossthe site

· Groundwater purging and sampling from the seven IEL wells and one additional well to the north-east ofthe hydraulic containment area, well 406

· Recording of groundwater temperature in the field

· Laboratory analysis

· Data assessment and reporting

1.4.1 Sampling Methodology

Prior to sampling, a round of depth to groundwater level measurements (‘dip round’) from the wells wascompleted. Water level (‘dip’) measurements were taken using an interface probe, which is capable ofdistinguishing between water and light/dense non-aqueous phase liquids (NAPLs). Light NAPLs (such asBTEX compounds in their pure phase) can form a floating later on the water table, while dense NAPLs canpool at the base of wells.

The total measured depth of each well was also gauged using the interface probe.

Groundwater was sampled in accordance with standard AECOM procedures, based on ISO 5667-18:2001and US EPA methods.

The total volume of standing water in each monitoring well to be sampled was calculated. Between three andfive times this volume was purged by hand from the monitoring well before sampling. This was to ensurethat a groundwater sample representative of that in the aquifer was collected. Each monitoring well isequipped with dedicated in-situ purging and sampling HDPE inertial-lift tubing to minimise the risk of cross-contamination.

Containment wells C1 and C2 are equipped with pumps which operate to provide hydraulic containmentalong the site’s down-gradient boundary. When these wells are pumping, purging is not required andgroundwater samples are normally collected directly from the sampling tap at the wellhead.

Pfizer Ringaskiddy has a number of EX-rated areas across the site and, for safety reasons; the use of petrol-powered motorised pumps or battery-powered field meters is not permitted. Therefore, unstable water qualityparameters (pH, electrical conductivity, dissolved oxygen, and oxidation-reduction potential) were not

recorded in May 2017, as the water quality meter is not intrinsically safe. Measurements of pH and electricalconductivity (EC) are required by the site’s IEL and were measured in the laboratory. Field temperaturereadings for all sampling points were measured using a spirit thermometer.

In accordance with AECOM sampling protocols, sampling was conducted while wearing single usedisposable nitrile gloves, which were changed between sampling events to reduce the risk of cross-contamination between wells. Groundwater samples were collected in sequence from wells beginning withhistorically low concentrations and progressing to wells with historically higher concentrations, to minimisethe risk of cross-contamination.

Groundwater samples, filtered and preserved where appropriate, were collected into laboratory-suppliedsample containers and were labelled on-site. Samples were stored in a chilled cool-box on site and duringovernight transit to the contract laboratory.

1.4.2 Laboratory Analyses

Groundwater samples were sent for analysis to Exova Jones Environmental, Flintshire, UK; an AECOMapproved laboratory with UKAS accreditation.

Groundwater samples were analysed for the following suites of parameters:

· Volatile organic compounds

· Alcohols

· Dissolved heavy metals (arsenic, cadmium, chromium, copper, lead, nickel, zinc and mercury)

· Ammoniacal nitrogen as N

· Major ions (chloride, potassium, sodium, nitrite, nitrate, phosphate, sulphate, nitrate, nitrite, magnesiumand calcium)

· Carbonate, bicarbonate and total alkalinity

· Ionic balance

A sample inventory is provided in Table 1, with a well inventory in Table 2, field observations are presented inTable 3 with a record of groundwater elevations in Table 4. Analytical results are presented in Tables 5 – 8.Long-term concentration trends for key wells and parameters are provided in Appendix A, with laboratorycertificates in Appendix B.

2. Results & Discussion of Monitoring Programme

2.1 Site Hydrogeology and Groundwater Flow

2.1.1 Water Quality Parameters

Unstable water quality parameters consisting of pH, electrical conductivity (both were measured in thelaboratory) and temperature (which was measured in the field) are given in Table 3 and summarised below.

Groundwater temperature from monitoring wells ranged from 12.5°C (well 7) to 14.5°C (well 205). Thenormal range for Irish groundwater (10°C – 12°C).

The majority of groundwater pH values were at or near neutral, with values ranging between 6.8 (well 501)and 7.7 (well C1). The typical pH range for Irish groundwater is 6 – 9 pH units. These results are comparableto those of previous monitoring rounds for the site.

Groundwater EC results in May 2017 indicated fresh to slightly brackish groundwater, with a range from482 µS/cm (well 409) to 1,195 µS/cm (well 702). The higher EC results (>1,000 µS/cm) for wells 702(1,195 µS/cm) and C1 (1,141 µS/cm) reflect their proximity to the coast and slight influence of saline water.The results recorded here are similar to those of previous monitoring rounds. For well 406, EC was637 µS/cm.

AECOM15

Groundwater abstraction from containment wells C1 and C2 is inferred to draw groundwater of a morebrackish quality from Monkstown Creek, giving rise to elevated EC readings in groundwater from some wells.All EC results for the monitoring wells were below the upper GTV limit of 1,875 µS/cm in May 2017.

2.1.2 Groundwater Flow Pattern

Groundwater elevations in the drift and bedrock wells have been contoured (see Figures 3 and 4). Waterlevel measurements for the IEL wells are presented in Table 4.

Groundwater elevations from the network of monitoring wells indicate that the general direction ofgroundwater flow in May 2017 is to the east, consistent with previous dip rounds (see Figures 3 and 4).Groundwater abstraction from hydraulic containment wells C1 and C2 has been designed to limit themigration of groundwater off-site to Monkstown Creek to the north and east of the site. Groundwatercontours for the bedrock aquifer (Figure 4) show that in May 2017 eastward and northward groundwater flowis being prevented in the area of the infilled glacial channel and that groundwater is being drawn back towardthe containment wells C1 and C2. The groundwater elevation in well 406 is 1.32 m OD, compared to 0.41 mOD in hydraulic containment well C1, indicating that well 406 is up hydraulic gradient of the containment well.

In the south-eastern corner of the site (OSP4 area) northward groundwater flow is apparent, as this area issome distance from the containment wells and it appears that groundwater flow under natural gradientconditions to Monkstown Creek is occurring.

Water level measurements from across the monitored wells show that the highest groundwater elevation iswithin the source area at well 501 (2.99 m OD), adjacent to OSP1. The lowest groundwater elevation acrossthe site was down-gradient of the source area at containment well C1 (0.41 m OD).

2.1.3 Field Observations

During the water level measurement round, no light/dense NAPL layers were identified in any of the wells.

The total depth of each well was measured on 15 May 2017 and has been compared to the recorded welldepths on installation; see Table 4.

Current details of well conditions are presented in Table 2 and measurements of siltation included in Table 4.

2.2 Laboratory Results

2.2.1 Assessment Guidelines

Results of laboratory analysis of groundwater samples are presented in Tables 5 – 8 and are compared witha range of generic groundwater assessment criteria, specifically the EPA Interim Guideline Values (IGVs),the Groundwater Threshold Values (GTVs) and the Dutch Intervention Values (DIVs).

IGVs were developed by the EPA using a number of existing water quality guidelines in use in Ireland,including existing national environmental quality standards, proposed common indicators for the newgroundwater directive, drinking water standards and Geological Survey of Ireland trigger values.

GTVs are defined in Irish law in Statutory Instrument No. 366 of 2016, European CommunitiesEnvironmental Objectives (Groundwater) (Amendment) Regulations, 2016. The GTVs are regulatoryguidelines, which were developed to give effect to the EU Groundwater Directive. Exceedance of athreshold value triggers further investigation to confirm whether a ‘Poor’ groundwater chemical status for thegroundwater body as a whole is indicated.

The DIVs represent concentrations, above which there may be a risk to human receptors, and above whichmore detailed site-specific risk assessment or remediation may be required in The Netherlands. Theseguidelines have no legal standing in Ireland but are included as they have historically been used as ascreening tool for contaminants at the Ringaskiddy site since 1994/5.

2.2.2 Volatile Organic Compounds (VOCs)

VOC results for Round 1 May 2017 are presented in Table 5, with historic data and time-series trends inAppendix A.

The highest concentration of total VOCs was detected in groundwater from well 501. VOCs detected ingroundwater from well 501 (adjacent to OSP1 building in the source area) in Round 1 2017 werepredominantly BTEX compounds:

· Benzene: 0.003 mg/L

· Toluene: 0.029 mg/L

· Ethyl benzene: 1.075 mg/L

· Total Xylene: 8.893 mg/L

Concentrations of BTEX compounds increased slightly in May 2017 compared with November 2016 results,in groundwater from well 501, where BTEX increased from 8.5 mg/L to 10 mg/L. However, prior to November2016, BTEX concentrations in groundwater from well 501 were generally above 50 mg/L.

The concentration of MTBE in well 501 decreased from 0.11 mg/L to 0.08 mg/L between November 2016and May 2017. Other VOCs, including: isopropylbenzene (0.018 mg/L), 1,3,5-trimethylbenzene (0.013 mg/L)and 1,2,4-trimethylbenzene (0.017 mg/L) were detected in groundwater from well 501 in May 2017. OnlyBTEX results exceeded relevant screening criteria for the sample taken from well 501 in May 2017.

Benzene was detected in groundwater from one of the other six licensed monitoring wells on site in May2017. Well C1, located down-gradient of the source area, had a benzene concentration of 0.026 mg/L, whichis above the GTV (0.00075 mg/L) and IGV (0.001 mg/L) but below the DIV (0.03 mg/L) screening criteria forbenzene in groundwater. Benzene was below the method detection limit (MDL) in groundwater from wells:7, 205, 404, 409, 702 and 406.

BTEX compounds were below MDLs in groundwater from wells 7, 205, 404, 409 and 702. Wells 7 and 205are located down-gradient of the source area; well 409 is adjacent to OSP3 and south of the source area;while well 702 is located near OSP4, in the south-eastern part of the site.

BTEX concentration trends since May 2005 are presented in Appendix A, Figures A1 to A4.

MTBE was not detected in groundwater from wells 7, 409 and 702 in May 2017. Where detected, MTBEconcentrations were not above the IGV (0.03 mg/L) in May 2017. MTBE was, however, detected above theGTV (0.01 mg/L) in four wells (205, 404, 501 and C1), with reported concentrations ranging from 0.008 mg/L(well 501) to 0.018 mg/L (well 205). MTBE concentrations for all four wells decreased between November2016 and May 2017.

Total VOC concentrations in groundwater in May 2017 were generally stable compared to November 2016.The main changes in concentrations detected between the monitoring events are as follows:

· Well 7 – all VOCs remained below their MDLs between November 2016 and May 2017.

· Well 205 – total VOC concentration decreased from 0.027 mg/L in November 2016 to 0.018 mg/L inMay 2017, with only MTBE detected. This is the lowest concentrations recorded since May 2007

· Well 404 – total VOC concentration decreased from 0.17 mg/L in November 2016 to 0.017 mg/L in May2017, with only MTBE detected. This is the lowest concentration recorded since November 2007

· Well 409 – total VOC concentration increased from below detection to 0.002 mg/L between November2016 and May 2017, with only chloroform detected. There have been intermittent low concentrations ofchloroform detected in groundwater from well 409. The last detection was in November 2015

· Well 501 – total VOC concentration increased from 8.7 mg/L in November 2016 to 10 mg/L in May 2017,primarily due to an increase in m- and p-xylene concentration from 7.6 mg/L in November 2016 to8.9 mg/L in May 2017.

· Well 702 – all VOCs remained below their MDLs between November 2016 and May 2017.

· Well C1 – total VOCs increased slightly from 0.023 mg/L in November 2016 to 0.044 mg/L in May 2017due to an increase in benzene concentration in May 2017, all other VOCs except MTBE were belowtheir MDLs.

A trend diagram for total VOC concentrations from May 2005 to May 2017 for wells 501 (source area) and205 (down-gradient of the source area) is presented in Figure 5. In addition, a trend diagram over the sameperiod for total BTEX concentrations for wells 501 and 205 is presented in Figure 6.

Total VOC and BTEX show declining trends in both 501 and 205, with the exception of an isolated increasein VOC in well 205 in November 2009.

2.2.3 Alcohols and Other Dissolved Organics

Results for alcohols and other dissolved organics in Round 1 May 2017 are presented in Table 6.

In May 2017, no alcohol compounds were detected in groundwater above the laboratory MDLs.

In May 2015 increased concentrations of alcohols had been detected in groundwater from well 501. Pfizersubsequently identified leaks in two weak effluent manholes, CS116 and CS124, which are located in closeproximity up-stream of well 501. Repair work to the aforementioned manholes was successfully completedon 05 February 2016 and both manholes passed pressure testing to EN1610. The absence of alcohol inboth 2016 sampling rounds and in Round 1 2017 further confirms that issues with these manholes havebeen successfully rectified.

Trend diagrams for THF and cyclohexane concentrations for all licensed wells are presented in Appendix A,Figures A6 and A7 respectively.

THF remains below the MDL (0.01 mg/L) in groundwater from wells: 7 (since November 2009), 205 (sinceMay 2011), 409 (since November 2009) and 702 (not detected since monitoring began).

Recent THF concentration trends in wells 404, 501 and C1 are summarised below:

· Well 404 – decreased from 0.062 mg/L in November 2016 to 0.052 mg/L in May 2017

· Well 501 – increased from below the MDL in November 2016 to 0.039 mg/L in May 2017

· Well C1 – increased from 0.111 mg/L in November 2016 to 0.139 mg/L in May 2017

· Well 406 – increased from below the MDL in November 2016 to 0.011 mg/L in May 2017

Cyclohexane concentrations remain below the MDL in groundwater from wells: 7 (since May 2007), 205(since May 2011), 409 (not detected since monitoring began), 702 (not detected since monitoring began), C1(since May 2009) and 406 (since November 1995).

In groundwater from well 501, cyclohexane was detected at 0.36 mg/L in May 2017, its lowest concentrationin over ten years.

Cyclohexane concentration in groundwater from well 404 decreased from 0.14 in November 2016 to belowthe MDL in May 2017.

Acetone concentrations remain below the MDL in groundwater from all wells.

Acetone was detected in well 404 at a concentration of 0.14 mg/L in November 2016 but declined below theMDL in May 2017.

Ethyl acetate remains below the MDL and has not been detected above its MDL since 1998.

2.2.4 Dissolved Heavy Metals

Metal results are presented in Table 7.

Cadmium, chromium, copper, lead, mercury, nickel and zinc were not detected above their respective MDLsin groundwater sampled from the seven IEL wells monitored in May 2017 and well 406.

Arsenic, was detected above the MDL (0.0025 mg/L) in groundwater from five of the seven IEL wellsmonitored in May 2017, wells 7, 205, 404, 501 and C1. Concentrations detected in groundwater from 7(0.013 mg/L), 205 (0.028 mg/L), 404 (0.019 mg/L) and 501 (0.015 mg/L) exceeded relevant assessmentcriteria, including the GTV of 0.0075 mg/L and the IGV of 0.01 mg/L. The arsenic concentration in well C1(0.006 mg/L) remained below the relevant assessment criteria.

Arsenic was also detected in groundwater from well 406 at 0.009 mg/L, exceeding the GTV.

The source of these trace arsenic detections in groundwater is considered to be from naturally-occurringmetallic minerals in the underlying limestone bedrock. Arsenic solubility increases under anaerobicgroundwater conditions, such as those found beneath the site.

2.2.5 Major Ions

Major ion results are presented in Table 8.

Nitrite was below the MDL at five of the seven IEL wells in May 2017 except at low concentrations ingroundwater from wells 7 (0.1 mg/L) and C1 (0.05 mg/L). Nitrite was also below detection in groundwaterfrom well 406.

Nitrate was detected above the MDL (0.2 mg/L) in groundwater from four of the seven wells sampled in May2017, with concentrations ranging from 0.7 mg/L (well 7) to 5.1 mg/L (well 409). All nitrate concentrationswere below applicable screening criteria. Nitrate was below detection in groundwater from well 406.

Calcium and magnesium were detected in groundwater from all wells sampled at concentrations belowrelevant assessment criteria.

Chloride was detected at concentrations between 10 mg/L and 35 mg/L in groundwater from wells 7, 409 and501. Chloride concentrations for wells 205, 404, 702 and C1 were higher, ranging from 123 mg/L to260 mg/L, with a concentration of 99 mg/L detected in groundwater from well 406.

Elevated sodium concentrations (>100 mg/L) were also reported for groundwater from wells 205, 404, 702and C1 with concentrations up to 168 mg/L (C1) reported. Wells with the highest sodium concentrationscorresponded to those with the highest chloride concentrations and EC measurements of >1,000 µS/cm.Elevated readings of these parameters are likely to be due to the coastal setting and influence of brackishwater from the coast, possibly drawn in by groundwater abstraction from the containment wells.

Potassium concentrations ranged from 1.0 mg/L in well 409 to 12.8 mg/L in well 702. Concentrations in 702and C1 (8.6 mg/L) were above the IGV of 5 mg/L, as was the potassium concentration in well 406; elevatedpotassium concentrations for these wells are also inferred to be linked to the site’s coastal setting.

Sulphate was detected in groundwater from all seven IEL wells sampled and well 406, with concentrationsfor all wells less than the IGV (200 mg/L) and GTV (187.5 mg/L).

Concentrations of ammoniacal-nitrogen in groundwater from wells 7, 205, 404, 501, C1 and well 406, rangedfrom 0.4 mg/L (well 7) to 1.42 mg/L (well 404) indicating reducing groundwater conditions in these wells. Theconcentrations of ammoniacal-nitrogen in the remaining wells 409 and 702 were below the MDL (0.02 mg/L).

In May 2017, as in previous groundwater monitoring rounds, iron concentrations for wells 409 and 702 werelow (below the MDL for iron in both wells). Manganese was also low in groundwater from well 702. Low ironconcentrations coupled with elevated nitrate and the absence of ammoniacal-nitrogen, as present at wells409 and 702, suggest more oxidising groundwater conditions. Iron and manganese are oxidised to insolubleforms when oxygen is present.

In a reducing environment, naturally occurring iron and manganese in the aquifer material can dissolve intogroundwater. As such, iron and manganese concentrations reported for wells 7, 205, 404, 501 and C1indicate reducing conditions and are consistent with previous IEL monitoring rounds and results forammoniacal nitrogen and nitrate.

Results for total alkalinity in groundwater from all seven IEL monitoring wells are due to the presence ofbicarbonate alkalinity only (as all carbonate alkalinity concentrations were below the MDL). Measurements of

alkalinity can reflect the groundwater’s buffering capacity to pH change, with higher concentrations allowingfor greater resistance. Concentrations of total alkalinity range between 228 mg/L (well C1) and 324 mg/L(well 7) and are similar to ranges reported by Johnston and McConvey6 for Dinantian Limestones elsewherein Ireland.

For all wells in May2017, the ionic balances are below ±10%. In general, an ionic balance difference within±10% is taken to indicate that sampling procedures and laboratory analytical practices are acceptable. Theabsence of certain parameters, such as fluoride, from the analysis suite may influence the ionic balancecalculations.

Major ion results for May 2017 were generally within the ranges reported for previous monitoring rounds.

2.3 Temporal Trends of Chemical of Potential Concern

Groundwater monitoring data is available for the Ringaskiddy site dating back over twenty years (to 1994/5).Historically, VOCs have been detected in groundwater from the site, most notably: BTEX hydrocarbons,alcohols and THF. Alcohol detections are intermittent, but for the most part undetected in recent years; whileBTEX and THF tend to persist, with long-term declining concentration trends becoming apparent.

In general, dissolved organic compound concentrations across the site have shown significant decreasessince the mid-1990s. This is due to a combination of factors, including:

· Engineering upgrades

· UST removal in the Solvent Recovery Area north of OSP1

· Contaminated groundwater recovery and continued operation of the hydraulic containment system

Recent trends (~10 years) in BTEX and total VOC concentrations in the source area (well 501) havedeclined from>150 mg/L to ≤10 (Figures 5 and 6). Both trends follow very similar patterns, as total VOCconcentrations in well 501 are largely composed of BTEX hydrocarbons.

Total VOC concentrations down-gradient of the source area at well C1 have been less than 1 mg/L sinceMay 2006. Historical VOC data is tabulated in Appendix A.

The MTBE concentration for well 501, located in the source area, decreased from 0.11 mg/L in November2016 to 0.008 mg/L in May 2017. Down-gradient of the source area, MTBE concentrations detected ingroundwater from wells 205 and 404 also decreased in May 2017, to 0.018 mg/L and 0.017 mg/Lrespectively, and have remained below 1 mg/L since November 2012 for both wells (see Appendix A - FigureA5).

The containment wells appear to capture MTBE-contaminated groundwater from these up-gradient wellsthrough the influence of pumping.

2.4 Review of Solvent Mass Recovery

Trend diagrams of solvent mass recovery via groundwater abstraction, from May 1996 to May 2017, arepresented in Figure 7A and 7B. Small quantities of solvent mass are being recovered from both containmentwells C1 and C2, with approximately 3.9 kg total VOCs being recovered between November 2016 and May2017.

It’s likely that residual groundwater contamination from the up-gradient source area is being significantlyattenuated naturally along its flow path down-gradient.

Figure 7A indicates that groundwater abstraction from the R-series wells on-site ceased in September 1999,due to excavation works at the southern UST tank farm. Groundwater abstraction from the RC-wells on-siteceased in May 2005 and the wells were decommissioned in August 2007 with agreement from the EPA.

AECOM20

A feasibility study on the impact of decommissioning the RC wells and nearby well 601 was commissionedby Pfizer and prepared by AECOM (URS report reference: 46171688) in May 2006. The study concludedthat cessation of pumping and decommissioning of the seven wells in the RC area would have negligibleimpact on off-site groundwater receptors.

The report recommended that specified actions be taken during decommissioning to ensure effectiveclosure. The report also noted that, despite cessation of pumping from the RC wells, the containment wellsC1 and C2 would continue to operate. Hydraulic containment provided by these wells is expected to preventmigration of contaminated groundwater from the site.

2.5 Conceptual Site Model

The site lies just above Monkstown Creek, with higher ground to the south and west sloping steeply towardsthe coast to the north and east. Bedrock consists of fractured, fine grained, unbedded limestone. Subsoilsconsist of low permeability deposits (comprising soft silts with some fine sand and gravel) ranging from 0.2 mto 16.7 m bgl, with a thick, in-filled glacial channel occupying an area north of the nature pond.

Under natural gradient conditions, groundwater in the limestone aquifer is thought to flow in a north eastdirection and discharge to Monkstown Creek (the principal groundwater receptor). However, due to theaction of hydraulic containment wells on site, installed in 1996, groundwater is contained in an area aroundwells C1 and C2 (see Figure 2 for locations). Schematic representations of geology underlying the PfizerRingaskiddy site are presented in AECOM’s 1995 site investigation report7, while the conceptual site model(CSM) was presented in AECOM 2006 risk assessment.

2.5.1 Hydraulic Containment

Since 1993, the main contaminated source area identified during site investigations was located in theformer southern UST farm, north of OSP1. Other source zones (of smaller extent) were identified in areas tothe north and north-west of the containment wells (see Figure 2). The controlled water quantitative riskassessment (AECOM, 2006) concluded that, in the event of containment wells C1 and C2 being turned off,contaminated groundwater from the identified source areas would not pose a significant risk to MonkstownCreek.

Historically, VOCs have been detected in groundwater from the site, most notably: BTEX (benzene, toluene,ethylbenzene and xylene) hydrocarbons, alcohols and tetrahydrofuran (THF). Alcohol detections areintermittent, while BTEX and THF tend to persist, though with long-term declining concentration trends beingapparent.

The hydraulic containment system installed in 1996 (wells C1 and C2) not only contains contaminatedgroundwater on site but was also designed to reduce the mass of dissolved phase VOCs migrating off-site toCork Harbour. To this end, groundwater is abstracted from wells C1 and C2 on a continuous basis. Themass of solvent recovered through operation of the hydraulic containment system is estimated from pumpingrates and analytical data from biannual monitoring. Assessment of containment system efficiency and theneed for rehabilitation works is incorporated in biannual monitoring reports.

In 1998, following a loss incident, the hydraulic containment system was augmented by the installation offree-phase product recovery wells. Recovery wells R1, R3 and R4 were installed in the solvent recoveryarea with additional recovery wells, RC1-RC6, installed in 2000. Solvent recovery from the R-series wellsceased in 1999 and from the RC-series of wells recovery ceased in May 2005; the RC-series weredecommissioned in May 2007.

Since the hydraulic containment system was commissioned, dissolved phase concentrations of BTEX andTHF have reduced further. More recently, MTBE concentrations peaked down-gradient of the solventrecovery area and subsequently declined (data available up to May 201).

AECOM21

A review of remedial options for the site was conducted in 2014 and completed in 20158. It was concludedthat the benefits of any scheme, over and above the mass recovery obtained with the current hydrauliccontainment system, are likely to be limited in nature due to the difficulties in effectively targeting anytreatment within the source zone and given the uncertainty of contaminant mass distribution within thecomplex limestone bedrock aquifer and/or the silty-sandy gravel drift unit directly overlying it. Practicalityissues, particularly relating to access in the operational solvent recovery and solvent tank farm areas,together with Health & Safety requirements, are likely to limit the effectiveness of the design of any schemefor enhancing mass recovery from the source area, which is located within an ATEX Zone area. The benefitsof any of the options assessed are considered likely to be outweighed by low sustainability.

2.5.2 Potential Pollutant Linkages

A summary of potential Source-Pathway-Receptor (SPR) linkages is outlined in the table below.

Potential SPR Linkages

Sources Pathways Potential Receptor

S3 Workers on-siteundertaking subsurfaceworks

Controlled WatersP4 Lateral migration of contaminantsthrough the bedrock aquifer

Controlled WatersS4 Monkstown Creek(pNHA 001979)

S5 Cork Harbour (SPA004030)

Based on the current site status and monitoring data it is considered that:

· The potential for ingestion of contaminated soil/dust and groundwater is low. The former northern andsouthern UST farms, key source areas for contaminated soil and groundwater, were removed in 1998and 1999 (along with associated contaminated soils, which were bio-remediated on site), respectively,reducing contaminant concentrations in groundwater. On-site personnel do not have routine contactwith either soil or groundwater.

· Similarly, the potential for dermal contact with contaminated soil/dust and groundwater is low, for thereasons outlined above.

· The potential for indoor inhalation of contaminant vapours on site is low, as the nearest occupiedbuilding in the vicinity of the source area is up-topographical and hydraulic gradient (OSP 1). Outdoorinhalation of volatile compounds emanating from contaminated soil and groundwater is also consideredlow, as contaminated soil and groundwater in the source areas have been remediated to an acceptablelevel with regard to exposure to human health via vapour inhalation.

· The potential for indoor/outdoor inhalation of contaminant vapours by workers on off-site properties isconsidered negligible, as there are no occupied properties down-gradient of the site and contaminated

groundwater is either captured by the containment wells or discharges to Monkstown Creek from thesite.

· There is a potential for on-site workers to be exposed to low level contamination in the source area ofthe Pfizer Ringaskiddy site if redevelopment requiring excavation is undertaken. However, if such workswere to be undertaken, then project-specific additional health and safety procedures would be put inplace to protect site workers (e.g. permit system, air monitoring with action levels, PPE, etc.).

· Given the site’s coastal setting and the fact that groundwater in this area is likely to be brackish, it isunlikely that wells for potable use are/will be located in the vicinity of the site.

· The mass of dissolved contaminants in groundwater migrating laterally through the bedrock aquifer fromthe source area towards Monkstown Creek is considered low. Two hydraulic containment wells capturegroundwater with dissolved contamination. In addition, dissolved phase organic contaminants are beingsignificantly attenuated along the groundwater flow path (through sorption, in-situ degradation, dilutionand dispersion).

3. Summary, Conclusions and Recommended Way Forward

3.1 Summary and Conclusion

Groundwater monitoring was undertaken between 15 and 17 May 2017 for Pfizer Ireland Pharmaceuticals attheir API plant, Ballintaggart, Ringaskiddy, Co. Cork (Pfizer Ringaskiddy). The scope of work included:groundwater level measurement in all accessible wells; sampling groundwater from seven on-site wells;analysis for parameters required by the site’s IEL and determination of the direction of groundwater flow.

In general, the groundwater flow pattern and long term declining solvent trends have remained consistent atPfizer Ringaskiddy and can be summarized as follows:

· Groundwater flow direction in both the subsoil and bedrock aquifers is in an eastward direction acrossthe western portion of the site. Moving further east, groundwater in the bedrock aquifer is contained inan area north of the nature pond by groundwater abstraction from two containment wells: C1 and C2. Itis understood from historic data that, under natural gradient conditions, groundwater flow in this areawould swing northward towards Monkstown Creek.

· A general overall declining trend in solvent concentrations has been evident in groundwater from the IELmonitored wells at Pfizer Ringaskiddy since the mid-1990s.

· Solvent mass recovery, as a result of groundwater abstraction from wells C1 and C2 (and historicallyfrom other wells), has followed an overall trend of decreasing mass loads over time. This is attributed toa combination of engineering up-grades, removal of source contaminants and groundwater abstractionitself. Ongoing natural attenuation of dissolved solvent concentrations along the groundwater pathwaydown-gradient of the source area has also reduced the overall mass recovered.

Conclusions from Round 1 May 2017 monitoring round are:

· No floating/sinking non-aqueous phase liquid layer was detected in any of the monitoring wells dipped.

· Total VOC concentrations in May 2017 were generally stable compared to November 2017, increasingslightly in groundwater from three wells.

· Alcohols and acetone were below detection in groundwater from all seven IEL monitoring wells in May2017.

· The THF concentration increased in groundwater from well 501 between November 2016 and May2017, from below the MDL to 0.04mg/L. THF also increased in groundwater from well C1 betweenNovember 2016 and May 2017, from 0.011 mg/L in November 2016 to 0.14 mg/L in May 2017. The THFconcentration decreased in groundwater from well 404 (from 0.062 mg/L in November 2016 to0.052 mg/L in May 2017).. THF remained below the MDL in groundwater from wells 7, 205, 409 and702.

· Cyclohexane was detected in groundwater from one well, 501 (0.36 mg/L) in May 2017. Cyclohexaneremained below MDL in the remaining six wells.

· In 2015, leaks were identified in two weak effluent manholes CS116 and CS124 located up-stream ofwell 501. Repairs to the manholes were completed in February 2016, with both manholes passingEN1610 pressure testing. Decreases in alcohol concentrations in 2016 and Round 1 2017 areconfirmation that repairs to the manholes have been successful.

· All licensed monitoring wells appeared to be in good condition during fieldwork and do not require repairor maintenance.

3.2 Recommended Way Forward

Based on results of the first round of IEL biannual groundwater monitoring conducted in May 2017, AECOMrecommends that groundwater containment and monitoring of those wells defined in the IE licence continuein accordance with EPA requirements in Round 2 2017.

NOTE

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

Please note we are only MCERTS accredited (UK soils only) for sand, loam and clay and any other matrix is outside our scope of accreditation.

Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40.

17/8821

WATERS

It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be

included unless we are requested to remove them.

All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35°C ±5°C unless

otherwise stated. Moisture content for CEN Leachate tests are dried at 105°C ±5°C.

Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat,

clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable

limits for most organic methods are 70 - 130% and for VOCs are 50 - 150%. When surrogate recoveries are outside the performance criteria but

the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected.

A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required.

Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40.

Please note we are not a UK Drinking Water Inspectorate (DWI) Approved Laboratory .

If you have not already done so, please send us a purchase order if this is required by your company.

The calculation of Pyrite content assumes that all oxidisable sulphides present in the sample are pyrite. This may not be the case. The calculation

may be an overesitimate when other sulphides such as Barite (Barium Sulphate) are present.

Where analytes have been found in the blank, the sample will be treated in accordance with our laboratory procedure for dealing with contaminated

blanks.

ISO17025 accreditation applies to surface water and groundwater and usually one other matrix which is analysis specific, any other liquids are

outside our scope of accreditation.

As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples.

Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately.

Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when

all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been

met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside

the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not

been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered

indicative only, but this does not mean the data is not valid.

Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact

the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable

containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and

any test results that may be compromised highlighted on your deviating samples report.

Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our

MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations

of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS

accredited.

Negative Neutralization Potential (NP) values are obtained when the volume of NaOH (0.1N) titrated (pH 8.3) is greater than the volume of HCl (1N)

to reduce the pH of the sample to 2.0 - 2.5. Any negative NP values are corrected to 0.

Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used.

All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary.

% Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings

listed in order of ease of fibre release.

NOTE

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

Please note we are only MCERTS accredited (UK soils only) for sand, loam and clay and any other matrix is outside our scope of accreditation.

Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40.

17/8954

WATERS

It is assumed that you have taken representative samples on site and require analysis on a representative subsample. Stones will generally be

included unless we are requested to remove them.

All analysis is reported on a dry weight basis unless stated otherwise. Results are not surrogate corrected. Samples are dried at 35°C ±5°C unless

otherwise stated. Moisture content for CEN Leachate tests are dried at 105°C ±5°C.

Surrogate compounds are added during the preparation process to monitor recovery of analytes. However low recovery in soils is often due to peat,

clay or other organic rich matrices. For waters this can be due to oxidants, surfactants, organic rich sediments or remediation fluids. Acceptable

limits for most organic methods are 70 - 130% and for VOCs are 50 - 150%. When surrogate recoveries are outside the performance criteria but

the associated AQC passes this is assumed to be due to matrix effect. Results are not surrogate corrected.

A dilution suffix indicates a dilution has been performed and the reported result takes this into account. No further calculation is required.

Where Mineral Oil or Fats, Oils and Grease is quoted, this refers to Total Aliphatics C10-C40.

Please note we are not a UK Drinking Water Inspectorate (DWI) Approved Laboratory .

If you have not already done so, please send us a purchase order if this is required by your company.

The calculation of Pyrite content assumes that all oxidisable sulphides present in the sample are pyrite. This may not be the case. The calculation

may be an overesitimate when other sulphides such as Barite (Barium Sulphate) are present.

Where analytes have been found in the blank, the sample will be treated in accordance with our laboratory procedure for dealing with contaminated

blanks.

ISO17025 accreditation applies to surface water and groundwater and usually one other matrix which is analysis specific, any other liquids are

outside our scope of accreditation.

As surface waters require different sample preparation to groundwaters the laboratory must be informed of the water type when submitting samples.

Where appropriate please make sure that our detection limits are suitable for your needs, if they are not, please notify us immediately.

Data is only reported if the laboratory is confident that the data is a true reflection of the samples analysed. Data is only reported as accredited when

all the requirements of our Quality System have been met. In certain circumstances where all the requirements of the Quality System have not been

met, for instance if the associated AQC has failed, the reason is fully investigated and documented. The sample data is then evaluated alongside

the other quality control checks performed during analysis to determine its suitability. Following this evaluation, provided the sample results have not

been effected, the data is reported but accreditation is removed. It is a UKAS requirement for data not reported as accredited to be considered

indicative only, but this does not mean the data is not valid.

Where possible, and if requested, samples will be re-extracted and a revised report issued with accredited results. Please do not hesitate to contact

the laboratory if further details are required of the circumstances which have led to the removal of accreditation.

Samples must be received in a condition appropriate to the requested analyses. All samples should be submitted to the laboratory in suitable

containers with sufficient ice packs to sustain an appropriate temperature for the requested analysis. If this is not the case you will be informed and

any test results that may be compromised highlighted on your deviating samples report.

Where an MCERTS report has been requested, you will be notified within 48 hours of any samples that have been identified as being outside our

MCERTS scope. As validation has been performed on clay, sand and loam, only samples that are predominantly these matrices, or combinations

of them will be within our MCERTS scope. If samples are not one of a combination of the above matrices they will not be marked as MCERTS

accredited.

Negative Neutralization Potential (NP) values are obtained when the volume of NaOH (0.1N) titrated (pH 8.3) is greater than the volume of HCl (1N)

to reduce the pH of the sample to 2.0 - 2.5. Any negative NP values are corrected to 0.

Where a CEN 10:1 ZERO Headspace VOC test has been carried out, a 10:1 ratio of water to wet (as received) soil has been used.

All samples will be discarded one month after the date of reporting, unless we are instructed to the contrary.

% Asbestos in Asbestos Containing Materials (ACMs) is determined by reference to HSG 264 The Survey Guide - Appendix 2 : ACMs in buildings

listed in order of ease of fibre release.
