Factual Report on Ground Investigation at Cole Green Inert Landfill Tarmac


1 INTRODUCTION

This investigation was carried out on the instructions of Royal Haskoning DHV (the Engineer)

on behalf of Tarmac (the Client).

The purpose of the work was to investigate ground conditions to determine the geotechnical

parameters of the site and to provide information on potential risks to human health and

controlled waters.

The work included an intrusive investigation, laboratory testing and the preparation of this

report, which contains a description of the site and the works carried out, the exploratory hole

logs, in-situ and laboratory testing results.

The ground investigation has been carried out using intrusive ground investigation techniques in

general accordance with the recommendations of BS5930: 1999 Code of Practice for Site

Investigations (including Amendment A2, 2010). Whilst every attempt is made to record full

details of the strata encountered in the exploratory holes, techniques of hole formation and

sampling will inevitably lead to disturbance, mixing or loss of material in some soils and rocks.

A comprehensive desk study, other than an inspection of geological maps, has not been

requested or undertaken as part of this investigation. Nor has a Preliminary Risk Assessment

been completed by Structural Soils Limited.

All information given in this report is based on the ground conditions encountered during the site

work, and on the results of laboratory and field tests performed during the investigation.

However, there may be conditions at the site that have not been taken into account, such as

unpredictable soil strata, contaminant concentrations, and water conditions between or below

exploratory holes. It should be noted that groundwater levels, gas concentrations and gas flows

usually vary due to seasonal, atmospheric and/or other effects and may at times differ to those

measured during the investigation.

This report was prepared by Structural Soils Limited for the sole and exclusive use of Tarmac in

response to particular instructions. Any other parties using the information contained in this

report do so at their own risk and any duty of care to those parties is excluded. No liability will

be accepted after a period of 6 years from the date of the report.



2 SITE DESCRIPTION

2.1 Location and Topography

The site is located to the south-east of Welwyn Garden City, Hertfordshire; immediately south of

Cole Green Lane and adjacent to Holwell Hyde Lane (see Site Location Map in Appendix A).

The site is situated to the west of B. P. Mitchell’s aggregate processing yard and is bounded to

the north and east by Cole Green Way, which forms part of National Cycle Route 61. The British

National Grid Reference of the site is TL 263 117.

Vehicular access to the site is gained through a locked gate on Holwell Hyde Lane. A public

footpath also originates at this point. The site is approximately 5.9 hectares in size (see

Exploratory Hole Location Plan in Appendix A) and is set at an average elevation of 80.8m

above Ordnance Datum.

Historically, the site was utilised as a landfill site, with landfill operations ceasing in the 1980s.

At the time the investigation took place, the site consisted of an open grassed area which slopes

gently downwards towards the south-west. Several methane venting pipes have been installed

around the site from previous works that have been undertaken. There are a number of natural

drains which cross the site, one of which runs adjacent to Holwell Hyde Lane. There is also a

fishing lake situated just beyond the south west corner boundary of the site.

The site is currently used as an informal public space and is utilised mainly by dog walkers.

2.2 Geology

Information on the geology of the site was obtained from the following sources published by the

the British Geological Survey (BGS):

BGS survey map (sheet 239, scale 1:50,000 published 1978).

The BGS digital geology map, which utilises the most up to date names for geological

units (www.bgs.ac.uk/data).

The BGS Lexicon of Named Rock Units, which provides typical descriptions for most

geological units (www.bgs.ac.uk/lexicon).

The site is shown to be underlain by the following descending sequence of strata:

3 FIELDWORK

3.1 Scope of Works

The following works were completed between 23rd

November and 21st December 2015 at

locations shown on the Exploratory Hole Location Plan in Appendix A:

TABLE 2: SCOPE OF INTRUSIVE WORKS

Number Exploratory Hole Hole Numbers

4 Cable Percussion Boreholes. BHIL01 to BHIL04

10 Machine Dug Trial Pits. TPIL01 to TPIL10

The exploratory holes typically encountered the following descending sequence of soils: Made

ground (clay capping and landfill material) underlain by gravelly clay, above gravel and chalk.

The scope of investigation and choice of investigation equipment was decided by Royal

Haskoning DHV in consultation with Structural Soils Ltd. Sampling and in-situ testing details

were specified by Royal Haskoning DHV.

As the site was classified as a “Red Site” by the British Drilling Association (BDA), appropriate

health and safety measures were employed during the site works. These measures included a

decontamination unit, aquifer protection in the boreholes, use of appropriate respiratory PPE and

disposable Tyvek overalls when sampling landfill materials, personal gas alarms and the use of

impermeable membranes at the exploratory positions.

The positions were selected by Royal Haskoning DHV, set out by Structural Soils Ltd. and

adjusted where necessary to take account of buried or overhead services, or other restrictions

The exploratory holes were logged by an engineer in accordance with the recommendations of

BS5930: 1999 (Amendment A2, 2010, which incorporates the requirements of BS EN ISO

14688-1, 14688-2 and 14689-1), and CIRIA Report C574 Engineering in Chalk. Detailed

descriptions, together with relevant comments, are given in the logs included in Appendix B.

Prior to the commencement of any exploratory hole or intrusive test, all positions were checked

for buried services by a specialist utility surveyor using a cable avoidance tool (CAT), signal

generator (‘genny’), and ground penetrating radar (GPR).

Inspection pits were hand dug at exploratory locations where noted on the relevant exploratory

hole logs.



On completion of the works, a survey of the exploratory hole locations was undertaken using

specialist Global Positioning System (GPS) equipment. The coordinates of each exploratory

hole were measured relative to British National Grid, and the level relative to Ordnance Datum.

These are shown on the exploratory hole logs contained in Appendix B which have been printed

with a reduced level column.

3.2 Cable Percussion Boreholes

The boreholes were drilled using a cable tool percussion drilling rig and were 300mm in

diameter, reducing to 150mm diameter when through the landfill material. Aquifer protection

measures were employed during drilling in the form of bentonite sealing plugs installed at the

base of the landfill material. The final depths of the boreholes were between 15.50m to 28.50m.

Small and bulk disturbed soil samples were taken from the boreholes at regular intervals.

100mm diameter undisturbed samples were also recovered from suitable strata within the

boreholes in accordance with BS EN ISO 22475-1. These samples were recovered using a thin

walled UT100 sampler.

Standard Penetration Tests (SPT) were carried out at specified intervals (see In-Situ Testing,

below).

Drilling equipment was jet-washed between boreholes at a specified location agreed with Royal

Haskoning DHV to help prevent cross contamination between boreholes.

3.3 Trial Pits

Machine dug trial pits were excavated using a wheeled mechanical excavator and were

approximately 2.50m x 0.60m in plan and up to 4.50m deep.

Small and bulk disturbed soil samples were taken from the trial pits at regular intervals. Water

samples were taken at each water strike. Hand vane and/or hand penetrometer tests were carried

out in the cohesive strata (within the pit where safe to do so, else on excavated material).

As with the boreholes, the excavator was also jet-washed to help prevent cross contamination.

3.4 Backfill, Monitoring Wells and Installations

Upon completion, 50mm diameter gas/groundwater monitoring wells and were installed in the

exploratory boreholes, the design having been decided by Royal Haskoning DHV. The

installation details are shown on the exploratory hole logs in Appendix B.



The monitoring well details are summarised in Table 3 below:

Cover Notes

BHIL01 50 9.00 1.50 to 9.00 Upstanding




Upon completion, the trial pits were backfilled with arisings, compacted in layers by the

excavator bucket. Excess arisings that could not be placed back into the trial pits were

stockpiled on an impermeable membrane and covered over pending further waste classification

assessment on the agreement of Royal Haskoning DHV and Tarmac. This stockpile was fenced

off to prevent access by members of the public and any wildlife present on site.

3.5 Chemical Contamination Sampling

Samples for contamination testing were taken from the exploratory holes by a Royal Haskoning

DHV geoenvironmental engineer present on site during the site works.

Water samples were also taken from the monitoring wells by Royal Haskoning DHV.

All samples were placed in appropriate contamination sample containers that were supplied by

the laboratory. Containers for volatiles testing of soil samples were filled to capacity. Any

water sample containers (with preservatives where required) were filled to capacity to minimise

volatilisation. All samples were then kept in cool boxes with ice packs and were transported to

the laboratory under Chain of Custody documentation, as promptly as possible to maintain

sample integrity.

3.6 In-Situ Testing

Standard Penetration Tests (SPT) were carried out in the exploratory holes, where noted in the

preceding sections, in accordance with BS EN ISO 22476-3 using a hammer which had been

calibrated for efficiency. The calibration certificate is included in Appendix C. Seating drives

have been recorded in increments of 75mm in accordance with recommended UK practice.



The SPT N-values are reported on the exploratory hole logs, on which the serial number of the

hammer used is recorded. The full results are presented in tabular format on the Summary of

Standard Penetration Tests in Appendix C, on which the normalised N60 values are also reported,

which are the equivalent N-value for a hammer delivering 60% of the theoretical drop energy.

Plots showing both N and N60 values versus depth and versus elevation are also included.

Where 50 test blows failed to achieve 300mm of penetration, the SPT N-value equivalent to that

for 300mm of penetration has been extrapolated and reported on the exploratory hole logs using

the guidance contained in CIRIA Report The Standard Penetration Test (SPT) - Methods and

Use (1995).

3.7 Monitoring and Post Fieldwork Environmental Sampling

Gas concentrations and groundwater levels were recorded in the monitoring wells by Royal

Haskoning DHV during the site works.

A single round of post-site work gas and groundwater monitoring was completed by Structural

Soils Ltd at the request of Royal Haskoning DHV on 8th

January 2015.

An infrared gas meter was used to measure concentrations of carbon dioxide (CO2), methane

(CH4) and oxygen (O2) in percentage by volume. Initial and steady state concentrations were

recorded. An integral flow meter was used to measure borehole flow rates (initial and steady

state) in litres per hour (l/hr). In addition the atmospheric pressure before and during monitoring,

together with the weather conditions were recorded. The results together with the temporal

(weather) conditions are tabulated in Appendix F.

The monitoring results are presented as follows: -

1(1): Gas flow within the monitoring well recorded in l/hr.

1(2): CO2, CH4, O2 and Lower Explosive Limit (LEL) concentrations in %.

1(3): Water level within the monitoring well.

The bracketed number signifies the order in which the readings were collected from the

installation.

At the time of writing, any future monitoring visits to the site are to be completed by Royal

Haskoning DHV.



4 LABORATORY TESTING

Samples for potential geotechnical testing were returned to Environmental Scientifics Group Ltd,

a UKAS accredited laboratory. Samples collected by a Royal Haskoning DHV

Geoenvironmental Engineer for potential contamination testing were sent directly from site to

Alcontrol Limited, an MCERTS and UKAS accredited chemical testing laboratory.

Geotechnical and contamination laboratory tests were scheduled by Royal Haskoning DHV.

4.1 Geotechnical Laboratory Testing

Geotechnical laboratory testing was generally carried out in accordance with BS1377: 1990,

Methods of Test for Soils for Civil Engineering Purposes, Parts 1 to 8. The number of tests

completed and the test methods used are summarised below. Where non-standard procedures

REPORT NOTES

Notes - Soil chemical analysis All results are reported as dry weight (<40°C). For samples with Matrix Codes 1 - 6 natural stones and brick and concrete fragments >10mm are removed or excluded from the sample prior to analysis and reported results corrected to a whole sample basis. For samples with Matrix Code 7 the whole sample is dried and crushed prior to analysis. Notes - General

This report shall not be reproduced, except in full, without written approval from Envirolab. Subscript "A" indicates analysis performed on the sample as received. "D" indicates analysis performed on the dried sample, crushed to pass a 2mm sieve, unless asbestos is found to be present in which case all analysis is performed on the sample as received. All analysis is performed on the dried and crushed sample for samples with Matrix Code 7 and this supersedes any "A" subscripts. All analysis is performed on the sample as received for soil samples which are positive for asbestos and/or if they are from outside the European Union and this supercedes any "D" subscripts. Superscript "M" indicates method accredited to MCERTS. If results are in italic font they are associated with an AQC failure. These are not accredited and are unreliable. A deviating samples report is appended and will indicate if samples or tests have been found to be deviating. Any test results affected may not be an accurate record of the concentration at the time of sampling and, as a result, may be invalid. TPH analysis of water by method A-T-007 Free and visible oils are excluded from the sample used for analysis so that the reported result represents the dissolved phase only. Asbestos in soil Asbestos in soil analysis is performed on a dried aliquot of the submitted sample and cannot guarantee to identify asbestos if present as discrete fibres/fragments. Stones etc. are not removed from the sample prior to analysis. Quantification of asbestos is a 3 stage process including visual identification, hand picking and weighing and fibre counting by sedimentation/phase contrast optical microscopy if required. If asbestos is identified as being present but is not in a form that is suitable for analysis by hand picking and weighing (normally if the asbestos is present as free fibres) quantification by sedimentation is performed. Where ACMs are found a percentage asbestos is assigned to each with reference to 'HSG264, Asbestos: The survey guide' and the calculated asbestos content is expressed as a percentage of the dried soil sample aliquot used. Predominant Matrix Codes: 1 = SAND, 2 = LOAM, 3 = CLAY, 4 = LOAM/SAND, 5 = SAND/CLAY, 6 = CLAY/LOAM, 7 = OTHER, 8 = Asbestos bulk ID sample. Samples with Matrix Code 7 are not predominantly a SAND/LOAM/CLAY mix and are not covered by our BSEN 17025 or MCERTS accreditations. Secondary Matrix Codes: A = contains stones, B = contains construction rubble, C = contains visible hydrocarbons, D = contains glass/metal, E = contains roots/twigs. IS indicates Insufficient sample for analysis. NDP indicates No Determination Possible. NAD indicates No Asbestos Detected. N/A indicates Not Applicable. Superscript # indicates method accredited to ISO 17025. Analytical results reflect the quality of the sample at the time of analysis only. Opinions and interpretations expressed are outside the scope of our accreditation. Please contact us if you need any further information.

Structural Soils Limited (Hemel Hempstead)18 Frogmore RoadHemel Hempstead

562072

This report shall not be reproduced, except in full, without written approval from Envirolab.

All analysis is performed on the dried and crushed sample for samples with Matrix Code 7 and this supercedes any "A" subscripts.

Superscript "M" indicates method accredited to MCERTS.

For complex, multi-compound analysis, quality control results do not always fall within chart limits for every compound and we have criteria for reporting in these situations.

If results are in italic font they are associated with such quality control failures and may be unreliable.

A deviating samples report is appended and will indicate if samples or tests have been found to be deviating. Any test results affected may not be an accurate record of the concentration

at the time of sampling and, as a result, may be invalid

Predominant Matrix Codes: 1 = SAND, 2 = LOAM, 3 = CLAY, 4 = LOAM/SAND, 5 = SAND/CLAY, 6 = CLAY/LOAM, 7 = OTHER.

Samples with Matrix Code 7 are not predominantly a SAND/LOAM/CLAY mix and are not covered by our BSEN 17025 or MCERTS accreditations.

Secondary Matrix Codes: A = contains stones, B = contains construction rubble, C = contains visible hydrocarbons, D = contains glass/metal, E = contains roots/twigs.

IS indicates Insufficient sample for analysis, NDP indicates No Determination Possible and NAD indicates No Asbestos Detected.

Superscript # indicates method accredited to ISO 17025.

Analytical results reflect the quality of the sample at the time of analysis only. Opinions and interpretations expressed are outside the scope of our accreditation.
