1. INTRODUCTION

JRE Environment (JRE) was retained by Clare County Council to complete groundwater monitoring and

sampling at the Central Waste Management Facility (CWMF) located at Ballyduffbeg, Inagh, Co. Clare. The

site is a closed landfill site with an operational bring centre. Monitoring and sampling was completed at

on-site and background sample locations external to the site to assess monthly and quarterly groundwater

quality. Sample locations are provided on Drawing 01-030108-01, attached.

The groundwater sampling completed in April and June 2021 were monthly monitoring and sampling

events. The sampling completed in May 2021 was a monthly and quarterly monitoring and sampling

event. This report provides the results of Quarter 2 (Q2) sampling programme for 2021 (i.e., April to May

2021).

All sampling was completed under the appropriate health and safety regulations, including; Safety, Health

and Welfare at Work Act, 2005 and the Safety, Health and Welfare at Work (General Application)

Regulations, 2007 and associated Regulations. All sampling was completed with reference to Schedule E

of Environmental Protection Agency (EPA) Waste Licence Ref. W0109-02 (Waste Licence). Sampling

frequency was completed with reference to Table E.5.5 of the Waste Licence.

2.1. Scope of Work

The following tasks were completed as part of the scope of work for the ground water sampling

assessment in Q2 of 2021:

➢ Measure depth to water in each monitoring well to determine potentiometric elevation and

determine purge volumes;

➢ Purge a minimum of three well volumes from each monitoring well prior to sample collection;

➢ Monitor and record field parameters (i.e., pH, electrical conductivity and temperature) during and

following purging for monthly sampling events and dissolved oxygen for quarterly sampling events.

➢ Submit monthly groundwater samples to Element Materials Technology (EMT), an UKAS accredited

laboratory, in laboratory supplied sample bottles for selective analysis of ammoniacal nitrogen;

➢ Submit quarterly groundwater samples to EMT in laboratory supplied sample bottles for selective

analysis of the following potential contaminants of concern (PCOCs): ammoniacal nitrogen, chloride,

iron, potassium, sodium, total oxidised nitrogen, total organic carbon, phenols, E. coli and total

coliforms.

➢ Prepare a report of groundwater results for Clare Co. Co.

2.2. Methodology

JRE personnel completed three (3) groundwater sampling events at CWMF between April and May 2021.

All groundwater samples were collected in appropriate laboratory supplied sample containers and

transported under chain-of custody to the EMT laboratory. JRE field personnel completed all field work

with reference to section 5.6 of the EPA monitoring manual, including the following:

• The water level within each monitoring well was measured using a Waterline water level dip meter to

determine the static water level and calculate the volume of water within each monitoring well.

• At least three borehole volumes of groundwater were purged from each monitoring well using

dedicated waterra tubing and inertial foot valves to ensure that the samples were representative of

true groundwater conditions.

• During purging pH, conductivity and temperature were monitored using calibrated equipment (pH

meter and conductivity meter) to determine when stabilisation had occurred.

• Purged water was disposed of away from the monitoring well to prevent recirculation.

• The observed condition of the sample and any odours from the borehole were noted as part of the

field sample sheet.

• Dedicated sampling equipment (i.e., waterra tubing) was used for each monitoring well to avoid the

risk of cross contamination.

• All reusable equipment (e.g., water level meters) were thoroughly cleaned after use using a non-

phosphate laboratory detergent and then fully rinsed with water.

• Samples for chemical analysis were transferred to appropriately labelled sample containers (and

preserved where required).

• Samples were transferred by JRE to a chilled cooler box immediately following sample collection. All

samples were labelled with a unique sample identification number and transported to the contract

laboratory under appropriate chain of custody documentation.

2.3. Regulatory Framework

The regulatory standards used to assess groundwater quality reflect relevant standards that are

presently in place in Ireland and the European Union (EU) and are contained in the following Regulations:

• European Communities Environmental Objectives (Groundwater) Regulations, 2010 – S.I. No. 9 of

2010; and

• European Communities Environmental Objectives (Groundwater)(Amendment) Regulations, 2016

– S.I. No. 366 of 2016

Where regulatory standards did not exist for a particular chemical parameter the analysis results were

compared to EPA guidelines to assess the sample quality. The guidelines used for comparison when

regulatory standards could not be applied included:

• Towards Setting Guideline Values for the Protection of Groundwater in Ireland - Interim Report,

Environmental Protection Agency, 2003.

2.3.1. Trigger levels

Based on historic groundwater sampling results for the CWMF site, Clare County Council submitted

proposed trigger levels for ammonia, potassium, total organic carbon (TOC) and iron to the EPA for

approval in early 2021. In April 2021 the EPA approved the groundwater trigger levels outlined in Tables

B through E. The analysis results are also compared to the trigger levels in the Tables below.

3. RESULTS

The analysis results tables for the groundwater samples collected at CWMF as part of the Waste Licence

compliance sampling programme are provided in Appendix I and the associated laboratory reports are

provided in Appendix II.

3.1. Field Parameters

Monitoring and sampling of all groundwater wells was completed on April 20th, May 25th and June 15th

2021. The results of the site monitoring program indicated the following:

• The depth to groundwater (below ground surface [bgs]) at the CWMF site in April 2021 ranged

between 2.80 m (BH4) and 22.46 m (BH11D) bgs. In May 2021 groundwater elevation ranged

between 2.74 m (BH4) and 22.42 m (BH11D) bgs and in June 2021 groundwater elevation ranged

between 2.85 m (BH4) and 22.47 m (BH11D) bgs;

• The pH values for groundwater wells sampled in April ranged between 6.54 (BH4) and 7.92

(O’Loughlins). In May the pH in groundwater ranged between 6.47 (MacInerney) and 7.88 (BH11D).

In June the pH in groundwater ranged between 6.52 (O’ Loughlin) and 7.85 (BH11D).

• Electrical conductivity readings were less than the 2016 Groundwater Regulation threshold value

of 1,875 µS/cm for all sampling events between April and June 2021. All readings in Q2 were less

than the EPA Guideline Value 1,000 µS/cm for electrical conductivity.

• Dissolved oxygen concentrations in groundwater samples collected in May 2021 ranged between

32% saturation (BH12S) and 56% saturation (Marrinan 2).

Electrical conductivity, pH and dissolved oxygen concentrations measured during all groundwater

monitoring and sampling events were within the applicable regulatory limits and/or EPA guideline limits

included in section 2.3 of this report.

3.2. Ammoniacal Nitrogen

Groundwater samples were collected on a monthly basis to assess concentrations of ammoniacal

nitrogen (NH4-N) in both on-site and off-site monitoring wells. The results of the analyses were

compared to the European Communities Environmental Objectives (Groundwater) (Amendment)

Regulations, 2016 and the results are outlined below.

3.2.1. Southern Area Wells

Monitoring well BH11D is located immediately at the southwest corner of the closed landfill body with

monitoring wells BH2, BH3 and BH13 located down gradient to the southwest. The analytical results for

samples collected from these wells indicated the following;

• The NH4-N concentrations in BH11D were less than the 2016 Groundwater Regulation limit (0.175

mg/l) for two (2) of the Three (3) submitted samples in Quarter 2, 2021. The sample collected in April

(0.22 mg/l) was greater than the 2016 Groundwater Regulation limit but did not exceed the ammonia

trigger action level for that well.

July 14th, 2021

Samples were collected from on-site monitoring wells located further to the south of the main landfill

body and close to the site road (i.e., BH2, BH3 and BH13),

• Concentrations of NH4-N in BH2 for Q2 were greater than the Regulatory limit in April (0.22 mg/l)

and May (0.32 mg/l) but were less than the limit in June (0.08 mg/l). No results exceeded the

ammonia trigger action level for that well.

• Concentrations of NH4-N in BH3 for Q2 were all greater than the Regulatory limit with

concentrations ranging between 0.35 mg/l (April) and 0.47 mg/l (May). No results exceeded the


• Concentrations of NH4-N in BH13 for Q2 were all greater than the Regulatory limit with

concentrations ranging between 0.37 mg/l (May) and 0.39 mg/l (April). No results exceeded the


The NH4-N concentrations found in BH11D, BH3, BH2 and BH13 were consistent with historic results for

these monitoring wells and no results exceeded the approved action trigger levels for wells BH11D, BH3,

BH2 and BH13.

Each of the three wells BH2, BH3 and BH13 are located below ground surface and have a manhole cover

to protect the well standpipes. Volumes of infiltrated surface water runoff exist in the base of each

manhole that has the potential to percolate into the underlying aquifer and may affect groundwater

sample quality. It is considered that if the elevated NH4-N concentrations in BH3 and BH13 were due to

the migration of landfill leachate then the concentrations in BH11D (i.e., at immediate boundary of the

waste body) would be significantly higher than those in wells located further from the waste body. The

elevated concentrations in down gradient wells BH2, BH3 and BH13 may be due to historic fertilization

regimes for the upgradient forestry or from adjacent peat-based soils.

3.2.2. West / Southwest Area Wells

Monitoring wells BH12S, BH12D and BH4 are located to the southwest and BH1a is located west of the

main landfill area; the analysis results for all wells indicated the following:

• The concentration of NH4-N in BH1a during all three (3) monitoring events in Q2, 2021 were greater

than the 2016 Groundwater Regulation limit with concentrations ranging between 0.47 mg/l (April)

and 0.48 mg/l (May & June). No results exceeded the ammonia trigger action level for that well.

• The NH4-N concentrations in BH4 during all three (3) monitoring events in Q2 were less than the

2016 Groundwater Regulation limit (0.175 mg/l).

• The NH4-N concentrations in BH12D during all three (3) monitoring events in Q2 were less than the


• The NH4-N concentrations in BH12S during all three (3) monitoring events in Q2 were less than the


The NH4-N concentrations found in BH12S, BH12D, BH4 and BH1a were consistent with historic results

for these monitoring wells.

3.2.3. Southeast Area Wells

Monitoring well BH8D is located immediately at the southeast corner of the closed landfill body and BH5

is located further down gradient, south from BH8D. The analysis results for both wells indicated the

following:

• The concentrations of NH4-N in BH5 were less than the 2016 Groundwater Regulation limit of 0.175

mg/l for all three (3) sampling events in Q2, 2021.

• The NH4-N concentration in BH8D in April (0.29mg/) and May (0.18 mg/l) were marginally greater

than the 2016 Groundwater Regulation limit (0.175 mg/l) and the NH4-N concentration in June

(<0.03 mg/l) was less than the 2016 Groundwater Regulation limit (0.175 mg/l). No results exceeded

the ammonia trigger action level for that well.

NH4-N concentrations in BH5 and BH8D are consistent with previous analytical results.

3.2.4. Northwest Area Wells

Monitoring wells BH6aD, BH6aS, BH14 and BH15 are located to the northwest of the main landfill area.

The analytical results for these wells indicated the following:

• NH4-N concentrations at BH6aD were greater than the 2016 Groundwater Regulation limit for all

sampling events during Q2 with concentrations ranging between 0.42 mg/l (May) and 0.43 mg/l

(April and June). No results exceeded the ammonia trigger action level for that well.

• The NH4-N concentrations in BH6aS were less than the 2016 Groundwater Regulation limit of 0.175

mg/l) for all samples collected in Q2, 2021.

• NH4-N concentrations at BH14 were greater than the 2016 Groundwater Regulation limit for all

sampling events during Q2 with concentrations ranging between 0.33 mg/l (April) and 0.35 mg/l

(June). No results exceeded the ammonia trigger action level for that well.

• BH15 contained NH4-N concentrations less than the 2016 Groundwater Regulation limit in Q2, 2021

with concentrations less than the laboratory limit of detection (i.e., <0.03 mg/l) for all three (3)

sampling events.

It is considered that if a persistent impact from leachate migration from the landfill existed it would be

evident in all wells in this area. Therefore, the marginally elevated NH4-N concentrations may be due to

other factors. The area around the wells is heavily forested. In the past it was a common forestry

management practice to significantly fertilise newly planted areas. Therefore, there may be residual

migration of nutrients into the groundwater table in the wells indicating elevated concentrations (e.g.,

BH6aD). All analysis results for NH4-N were consistent with historic results and no results exceeded the

approved ammonia trigger action levels.

3.2.5. Background Wells

One (1) on-site background monitoring well (BH9c) and four (4) off site wells (i.e., O’Loughlin Marinan

1, Marinan 2 and McInnerney) were sampled during Q2 2021. It should be noted that the off-site wells

are historical shallow groundwater wells that are open to surface infiltration and may not be fully

representative of true groundwater conditions. The analytical results for these wells indicated the

following;

• The NH4-N concentrations in all samples from BH9c in Q2 (i.e., results ranged between 0.20 mg/l

and 0.21 mg/l) were marginally greater than the 2016 Groundwater Regulation limit of 0.175 mg/l

but no results exceeded the ammonia trigger action level for that well.

• The samples collected at the O’ Loughlins well indicated that NH4-N concentrations were less than

the 2016 Groundwater Regulation limit of 0.175 mg/l for all three sampling events in Q2, 2021.

• The samples collected at the McInnerney well indicated that NH4-N concentrations were less than

the 2016 Groundwater Regulation limit of 0.175 mg/l for all three sampling events in Q2, 2021.

• The samples collected at the Marinan 1 well during the April (0.70 mg/l) and June 2021(0.23 mg/l)

monitoring indicated that NH4-N concentrations were greater than the 2016 Groundwater

Regulation limit of 0.175 mg/l but was less than the limit May (0.09 mg/l). No results exceeded the

ammonia trigger action level for that well

• The samples collected at the Marinan 2 well during the April (0.19 mg/l) and June 2021(0.21 mg/l)

monitoring indicated that NH4-N concentrations were greater than the 2016 Groundwater

Regulation limit of 0.175 mg/l but was less than the limit May (0.08 mg/l). No results exceeded the

ammonia trigger action level for that well

Historically, water samples collected from the off-site shallow wells indicated that the concentrations of

NH4-N fluctuate in each well based on the activities taking place around the well locations (e.g., cattle

grazing). Each of the external wells are located on agricultural land and water quality is influenced by

surface runoff or vertical migration of contaminants from the surrounding lands (e.g., fertilizers or

manures spread on the land). All analysis results for NH4-N were consistent with historic results and no

results exceeded the approved ammonia trigger action levels.

3.3. TON & TOC

Quarterly groundwater samples were collected from all nineteen (19) monitoring wells in May, 2021 to

assess concentrations of total oxidised nitrogen and total organic carbon. The results indicated the

following;

• All monitoring wells sampled contained concentrations of TON that were less than the laboratory

detection limit of 0.2 mg/l.

• Four (4) of the nineteen (19) monitoring well locations contained detectable concentrations of total

organic carbon (TOC). The wells with detectable TOC were BH4 (9 mg/l), Marinan 1 (5 mg/l),

Marinan 2 (19 mg/l) and McInnerney (15 mg/l). All other monitoring well locations contained

concentrations of TOC that were less than the laboratory detection limit of 2 mg/l. All analysis

results for TOC were consistent with historic results and no results exceeded the approved TOC

trigger action levels.

3.4. Inorganics

Quarterly groundwater samples were collected from all nineteen (19) monitoring wells in May, 2021 and

submitted for iron, potassium, chloride and sodium analysis. No standards are included in the 2010 or

2016 Groundwater Regulations for iron or potassium so the results for these parameters were compared

to the EPA Guideline Values for the Protection of Groundwater in Ireland Interim Report, 2003 (EPA

Groundwater Guideline Values). The analysis results indicated the following:

• All of the 19 submitted samples contained sodium concentrations less than the Regulatory limit of

150 mg/l with concentrations ranging between 6.1 mg/l (Marrinan 2 & McInnerney) and 61.2 mg/l

(BH1a).

• All of the 19 submitted samples contained a potassium concentration less than the EPA

Groundwater Guideline Value of 5 mg/l. Submitted samples contained potassium concentrations

that ranged between 0.9 mg/l (BH4 and BH12D) and 3.4 mg/l (O’ Loughlin).

• All of the 19 submitted samples contained a chloride concentration less than the 2016 Groundwater

Regulation threshold value of 187.5 mg/l with concentrations ranging between 7.3 mg/l (BH4) and

49.7 mg/l (BH9c).

• four (4) of the 19 submitted samples contained an iron concentration greater than the EPA Guideline

value of 200 µg/l (i.e., BH1a- 238 µg/l; BH4- 291 µg/l; Marrinan 1- 239 µg/l and Marinan 2 – 420

µg/l). The remaining fifteen (15) samples contained iron concentrations less than the EPA Guideline

value limit of 200 µg/l. Samples from Marinan 1 and Marinan 2 were less than the Trigger Action

levels for those wells.

3.5. Phenols

No standards are included in the 2010 or 2016 Groundwater Regulations for phenols. Therefore, the

results for the quarterly sampling programme completed in May 2021 were compared to the EPA

Guideline Values for the Protection of Groundwater in Ireland Interim Report, 2003.

All submitted groundwater samples in Q2, 2021 contained concentrations of phenols less than the

laboratory detection limit of 0.15 µg/l and less than the EPA groundwater guideline value of 0.5 µg/l

3.6. Microbiology

Quarterly groundwater samples were collected in May, 2021 and submitted for E. coli and Total Coliform

analysis with the results compared to the applicable groundwater quality standard. The analysis results

indicated the following:

• Eight (8) of the 19 submitted samples contained Total Coliforms greater than the Regulatory limit of

0 MPN/ 100ml (i.e., BH2 – 21.3 MPN/100ml, BH3 – 2419 MPN/100ml, BH4 – 2419 MPN/100ml, BH5

– 2419 MPN/100ml, BH6aS – 1 MPN/100ml, O’ Loughlin – 2419 MPN/100ml, Marrinan 1 – 770

MPN/100ml and Marrinan 2 – 2419 MPN/100ml). All other samples contained Total Coliform counts

of 0 MPN/100 ml.

• Three (3) of the 19 submitted samples contained concentrations of E. coli concentrations greater

than the Regulatory limit of 0 MPN/100 ml (i.e., BH3 – 14.1 MPN/100ml, BH4 – 488 MPN/100ml,

and Marinan 2 – 35 MPN/100ml). All remaining wells contained E. coli concentrations of 0

MPN/100ml.

4. QUALITY ASSURANCE / QUALITY CONTROL

Groundwater sampling was completed according to JRE’s preferred operating procedures (POPs). Upon

collection, groundwater samples were immediately transferred to appropriate laboratory prepared

bottles, containing appropriate preservatives where required, and stored in chilled coolers for shipment

with chain-of-custody documentation.

NOTE

NOTES TO ACCOMPANY ALL SCHEDULES AND REPORTS

21/5924

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 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.

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

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

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

All analysis is reported on a dry weight basis unless stated otherwise. Limits of detection for analyses carried out on as received samples are not

moisture content corrected. 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.

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

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.

% 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.

Sufficient amount of sample must be received to carry out the testing specified. Where an insufficient amount of sample has been received the

testing may not meet the requirements of our accredited methods, as such accreditation may be removed.

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.

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.

WATERS

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

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.


All samples should be submitted to the laboratory in suitable containers with sufficient ice packs to sustain an appropriate temperature for the

requested analysis. The temperature of sample receipt is recorded on the confirmation schedules in order that the client can make an informed

decision as to whether testing should still be undertaken.

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

blanks.

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.

REPORTS FROM THE SOUTH AFRICA LABORATORY

Any method number not prefixed with SA has been undertaken in our UK laboratory unless reported as subcontracted.

Measurement uncertainty defines the range of values that could reasonably be attributed to the measured quantity. This range of values has not

been included within the reported results. Uncertainty expressed as a percentage can be provided upon request.

ABBREVIATIONS and ACRONYMS USED

ISO17025 (UKAS Ref No. 4225) accredited - UK.

ISO17025 (SANAS Ref No.T0729) accredited - South Africa

Indicates analyte found in associated method blank.

Dilution required.

MCERTS accredited.

Not applicable

No Asbestos Detected.

None Detected (usually refers to VOC and/SVOC TICs).

No Determination Possible

Calibrated against a single substance

Surrogate recovery outside performance criteria. This may be due to a matrix effect.

Results expressed on as received basis.

AQC failure, accreditation has been removed from this result, if appropriate, see 'Note' on previous page.

Results above calibration range, the result should be considered the minimum value. The actual result could be significantly

higher, this result is not accredited.
