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.
May 2014 Report No 1305 Factual Report Page 3 of 7
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.

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.

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
Alcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light
microscopy and central stop dispersion staining, based on HSG 248 (2005).

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
Sampled on date not provided
Sample holding time exceeded in laboratory
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.

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
Alcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light
microscopy and central stop dispersion staining, based on HSG 248 (2005).

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
Sampled on date not provided
Sample holding time exceeded in laboratory
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.

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
Alcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light
microscopy and central stop dispersion staining, based on HSG 248 (2005).

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
Sampled on date not provided
Sample holding time exceeded in laboratory
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.

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
Alcontrol Laboratories (Hawarden) in-house method of transmitted/polarised light
microscopy and central stop dispersion staining, based on HSG 248 (2005).

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

Incorrect container received
Deviation from method
Holding time exceeded before sample received
Samples exceeded holding time before presevation was performed
Sampled on date not provided
Sample holding time exceeded in laboratory
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.
