1 INTRODUCTION

In February 2014 Apex Drilling Services (APEX) was commissioned by Parsons Brinckerhoff (PB)

on behalf of Torfaen County Borough Council to carry out a ground investigation at Llantarnam

Secondary School. The investigation was required to obtain geotechnical and geo-environmental

information as well as groundwater monitoring for a proposed new school.

The scope of the investigation, which was specified by PB, comprised cable percussive boreholes,

trail pitting, in situ testing and laboratory testing. The investigation was carried out in accordance

with the contract specification, Eurocode 7 and relevant related standards identified below (see

also References). The fieldwork was carried out between 24th and 28th February 2014.

This report presents the factual records of the fieldwork and laboratory testing. The data is also

presented separately in digital format.

2 THE SITE AND GEOLOGY

2.1 The Site

The site is located at Llantarnam Secondary School, approximately 2km south east of Cwmbran

town centre, as shown in Figure 1, Site Location Plan, Enclosure G.

The area of investigation currently comprises of open grassed playing fields. The site is bounded

to the north by steel palisade fencing with the secondary school and a leisure centre beyond.

Residential properties are located to the east, south and west of the site. Access to the site is via

the school entrance on Llantarnam Road.

The topography of the site is generally flat with little difference in levels (see Ground Level on the

exploratory logs, Enclosure A).

The centre of the site is at National Grid reference ST 305 933.


2.2 Published Geology

The published geological map of the area, BGS Sheet 249, show the superficial deposits to

comprise of undifferentiated River Terrace Deposits consisting of sands and gravels with localised

clay and silt deposits.

The solid geology comprises Raglan Marl Formation of the Lower Old Red Sandstone Unit. this

typically consists of reddish brown mudstone, siltstone and sandstone. The strata generally dips

towards the west, at a dip generally between 12 and 18 degrees.

3 FIELDWORK

3.1 General

The fieldwork which was specified by PB was carried out in general accordance with BS 5930+A2

(2010), BS EN 1997-2 (2007), BS EN ISO 22475-1 (2006) and BS 10175 (2011).

Standard Penetration Testing was undertaken during cable percussive boring, the results are

presented within the borehole logs.

Whilst undertaking geo-environmental sampling a best practice policy was observed which

included using new disposable nitrile gloves for each sample interval, ensuring appropriate sample

containers were used, cleaning tools to prevent cross contamination, keeping samples in cool

boxes containing ice packs and dispatching samples at the earliest opportunity, complete with

chain of custody, to the testing laboratory.

No visual or olfactory evidence of contamination was observed in any of the boreholes or trial pits.

The exploratory hole locations were selected by PB. The locations and elevations of the

exploratory holes were surveyed by John Vincent Surveys Ltd. on completion of the fieldwork.

The positions of the exploratory holes are shown on the Exploratory Hole Location Plan in

Enclosure G.


3.2 Exploratory Holes

The exploratory holes are listed in the following table.

SUMMARY OF EXPLORATORY HOLES

TYPE QUANTITY MAXIMUM DEPTH (m)

REMARKS

Light Cable Percussion Borehole 3 6.80 Designated BH1 to BH3

Trial Pits 11 3.20 Designated TP1 to TP11

The exploratory hole records are presented in Enclosure A and should be read in conjunction with

the Key which is included in that enclosure. The records provide descriptions of the materials

encountered in accordance with BS EN ISO 14688-1 (2002) and 14689-1 (2003), for soils and

rocks respectively, as amplified by BS 5930+A2 (2010).

The records also give details of the samples taken together with observations made during

operations. Photographs of the trial pits are presented in Enclosure F.

3.3 Instrumentation and Monitoring

The instruments installed in the exploratory holes are shown on the logs. Records of groundwater

level monitoring, using a dip meter, carried out by Apex Drilling during and after the fieldwork

period are presented in Enclosure B.

Gas monitoring was undertaken by Apex Drilling using a Geotech 2000 gas monitor and GF60 flow

monitor on 3 separate fortnightly visits. Water sampling was undertaken on the first visit after 3

well volumes of water had been purged

A best practice policy was observed during water sampling which included decontaminating of

apparatus using clean water, using appropriate water containers, storing samples in cool boxes

with ice packs and dispatching samples, complete with chain of custody, to the ALcontrol testing

laboratory at the earliest opportunity.


3.4 In Situ Testing

In situ testing was carried out in accordance with the relevant standards as tabulated below. The

testing is summarised in the following table and the results are presented in Enclosure C unless

NOTES 1 Soils and rocks are described in accordance with BS EN ISO 14688-1 (2002) and 14689-1 (2003) respectively as

amplified by BS 5930+A2 (2010).

2 For fine soils consistency determined in the field by the logger is reported for those strata where undisturbed samples are available. The consistency is qualified and given (in brackets) when, in the opinion of the logger, the sample is disturbed but the assessed consistency is reasonably representative of the in situ conditions; in these circumstances it will normally underestimate consistency in situ. No consistency is given where the samples available are too disturbed to allow a reasonable assessment.

3 Evidence of the occurrence of very coarse particles (cobbles and boulders) is presented on the logs, however, because of their size in relation to the exploratory hole these records may not be fully representative of their size and frequency in the ground mass.

4 The declination of bedding and joints is given with respect to the normal to the core axis. Thus in a vertical borehole this will be the dip.

5 The assessment of SCR, RQD and Fracture Spacing excludes artificial fractures

6 Strata legends are in accordance with BS 5930+A2 (2010).

7 Water level observations of discernible entries during the advancing of the exploratory hole are given at the foot of the log and in the Legend column. The term "none observed" is used where no discrete entries are identified although this does not necessarily indicate that the hole has not been advanced below groundwater level. Under certain conditions groundwater cannot be observed, for instance, drilling with water flush or overwater, or boring at a rate much faster than water can make its way into the borehole (ref BS5930+A2:2010, Clause 47.2.7). In addition, where appropriate, water levels in the hole at the time of recovering individual samples or carrying out in situ tests and at shift changes are given in the Records column.

8 The borehole logs present the results of Standard Penetration Tests recorded in the field without correction or interpretation. However, in certain ground conditions (eg high hydraulic head or where very coarse particles are present) some judgement may be necessary in considering whether the results are representative of in situ mass conditions.

These descriptions are only intended to act as a cross check if sample identities are questioned, and to provide a log of

sample matrices with respect to MCERTS validation. They are not intended as full geological descriptions.

We are accredited to MCERTS for sand, clay and loam/topsoil, or any of these materials - whether these are derived from

naturally ocurring soil profiles, or from fill/made ground, as long as these materials constitute the major part of the sample.

Other coarse granular materials such as concrete, gravel and brick are not accredited if they comprise the major part of the

sample.

Superseded Report:

Appendix

1. Results are expressed on a dry weight basis (dried at 35ºC) for all soil analyses except

for the following: NRA and CEN Leach tests, flash point LOI, pH, ammonium as NH 4 by the

BRE method, VOC TICS and SVOC TICS.

2. Samples will be run in duplicate upon request, but an additional charge may be incurred.

3. If sufficient sample is received a sub sample will be retained free of charge for 30 days

after analysis is completed (e-mailed) for all sample types unless the sample is destroyed

on testing. The prepared soil sub sample that is analysed for asbestos will be retained for a

period of 6 months after the analysis date. All bulk samples will be retained for a period of 6

months after the analysis date. All samples received and not scheduled will be disposed of

one month after the date of receipt unless we are instructed to the contrary. Once the initial

period has expired, a storage charge will be applied for each month or part thereof until the

client cancels the request for sample storage. ALcontrol Laboratories reserve the right to

charge for samples received and stored but not analysed.

4. With respect to turnaround, we will always endeavour to meet client requirements

wherever possible, but turnaround times cannot be absolutely guaranteed due to so many

variables beyond our control.

5. We take responsibility for any test performed by sub -contractors (marked with an

asterisk). We endeavour to use UKAS/MCERTS Accredited Laboratories, who either

complete a quality questionnaire or are audited by ourselves. For some determinands there

are no UKAS/MCERTS Accredited Laboratories, in this instance a laboratory with a known

track record will be utilised.

6. When requested, the individual sub sample scheduled will be analysed in house for the

presence of asbestos fibres and asbestos containing material by our documented in house

method TM048 based on HSG 248 (2005), which is accredited to ISO17025. If a specific

asbestos fibre type is not found this will be reported as “Not detected”. If no asbestos fibre

types are found all will be reported as “Not detected” and the sub sample analysed deemed

to be clear of asbestos. If an asbestos fibre type is found it will be reported as detected (for

each fibre type found). Testing can be carried out on asbestos positive samples, but, due

to Health and Safety considerations, may be replaced by alternative tests or reported as No

Determination Possible. The quantity of asbestos present is not determined unless

specifically requested.

7. If no separate volatile sample is supplied by the client, or if a headspace or sediment is

present in the volatile sample, the integrity of the data may be compromised. This will be

flagged up as an invalid VOC on the test schedule and the result marked as deviating on

the test certificate.

8. If appropriate preserved bottles are not received preservation will take place on receipt .

However, the integrity of the data may be compromised.

9. NDP -No determination possible due to insufficient/unsuitable sample.

10. Metals in water are performed on a filtered sample, and therefore represent dissolved

metals -total metals must be requested separately.

11. Results relate only to the items tested.

12. LODs for wet tests reported on a dry weight basis are not corrected for moisture

content.

13. Surrogate recoveries -Most of our organic methods include surrogates, the recovery

of which is monitored and reported. For EPH, MO, PAH, GRO and VOCs on soils the

result is not surrogate corrected, but a percentage recovery is quoted. Acceptable limits for

most organic methods are 70 -130 %.

14. Product analyses -Organic analyses on products can only be semi -quantitative due to

the matrix effects and high dilution factors

employed.

15. Phenols monohydric by HPLC include phenol, cresols (2-Methylphenol, 3-Methylphenol

and 4-Methylphenol) and Xylenols (2,3 Dimethylphenol, 2,4 Dimethylphenol, 2,5

Dimethylphenol, 2,6 Dimethylphenol, 3,4 Dimethyphenol, 3,5 Dimethylphenol).

16. Total of 5 speciated phenols by HPLC includes Phenol, 2,3,5-Trimethyl Phenol,

2-Isopropylphenol, Cresols and Xylenols (as detailed in 15).

17. Stones/debris are not routinely removed. We always endeavour to take a

representative sub sample from the received sample.

18. In certain circumstances the method detection limit may be elevated due to the sample

being outside the calibration range. Other factors that may contribute to this include

possible interferences. In both cases the sample would be diluted which would cause the

method detection limit to be raised.

19. Mercury results quoted on soils will not include volatile mercury as the analysis is

performed on a dried and crushed sample.

Identification of Asbestos in Bulk Materials & Soils

The results for identification of asbestos in bulk materials are obtained from supplied bulk

materials which have been examined to determine the presence of asbestos fibres using

Alcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light

microscopy and central stop dispersion staining, based on HSG 248 (2005).

The results for identification of asbestos in soils are obtained from a homogenised sub

sample which has been examined to determine the presence of asbestos fibres using



-Fibrous Tremolite

-Fibrous Anthophyllite

-Fibrous Actinolite

Blue AsbestosCrocidolite

Brown AsbestosAmosite

White AsbestosChrysotile

Common NameAsbestos Type

-Fibrous Tremolite


-Fibrous Actinolite





Visual Estimation Of Fibre Content

Estimation of fibre content is not permitted as part of our UKAS accredited test other than :

-

Trace -Where only one or two asbestos fibres were identified.

Further guidance on typical asbestos fibre content of manufactured products can be

found in HSG 264.

The identification of asbestos containing materials and soils falls within our

schedule of tests for which we hold UKAS accreditation, however opinions,

interpretations and all other information contained in the report are outside the

scope of UKAS accreditation.

Sample Deviations

Container with Headspace provided for volatiles analysis

Incorrect container received

Deviation from method

Holding time exceeded before sample received

Samples exceeded holding time before presevation was performed

Sample holding time exceeded due to sampled on date

Sample Holding Time exceeded - Late arrival of instructions.

Asbestos

General20. For the BSEN 12457-3 two batch process to allow the cumulative release to be

calculated, the volume of the leachate produced is measured and filtered for all tests. We

therefore cannot carry out any unfiltered analysis. The tests affected include volatiles

GCFID/GCMS and all subcontracted analysis.

21. For all leachate preparations (NRA, DIN, TCLP, BSEN 12457-1, 2, 3) volatile loss may

occur, as we do not employ zero headspace extraction.

22. We are accredited to MCERTS for sand, clay and loam/topsoil, or any of these

materials - whether these are derived from naturally occurring soil profiles, or from fill /made

ground, as long as these materials constitute the major part of the sample. Other coarse

granular material such as concrete, gravel and brick are not accredited if they comprise the

major part of the sample.

23. Analysis and identification of specific compounds using GCFID is by retention time

only, and we routinely calibrate and quantify for benzene, toluene, ethylbenzenes and

xylenes (BTEX). For total volatiles in the C5 -C12 range, the total area of the

chromatogram is integrated and expressed as ug /kg or ug/l. Although this analysis is

commonly used for the quantification of gasoline range organics (GRO), the system will

also detect other compounds such as chlorinated solvents, and this may lead to a falsely

high result with respect to hydrocarbons only. It is not possible to specifically identify these

non-hydrocarbons, as standards are not routinely run for any other compounds, and for

more definitive identification, volatiles by GCMS should be utilised.
