Report 15079 Page 1
1. INTRODUCTION
This report sets out the results of the field work and laboratory testing for a ground investigation
carried out by Strata Surveys Limited for Burnley Borough Council Street Scene-Engineering
Services.
The works were carried out under Framework Agreement for Ground Investigation 2011-2014.
The investigation was required in connection with the development of urban derelict ground
A Desk Study Phase 1 Risk Assessment Report was not undertaken as part of this investigation.
Historical maps for an adjacent site have been used to discuss the development of this area.
The object of the investigation was to obtain information on the ground conditions and soil
properties for use in the design and construction of foundations on the site and for the initial
assessment of the potentially contaminated soil risk.
The ground investigation has been carried out in accordance with the relevant standards for ground
investigation. Details of the relevant standards are given in the references to this report.
2. SITE DESCRIPTION
The site is located to the west of Princess Way, is bounded to the north by Holme Road. Bounded
to the west by the River Calder and to the south by the former Waste recycling and Transfer Depot,
to be developed for 2/3 storey offices and workshop accommodation.
Report 15079 Page 2
The site is grassed, with raised mounds from the former demolition and clearance of the old
housing on the site. The site slopes gradually downward from the north east to the south west. The
ground surface is gently undulating.
3. HISTORICAL SETTING
Historical plans for an adjacent site have been used to assess the historical development of the
area.
The 1848 1:10000 map shows the site area in open land, the Calder Vale Works is shown. There
are numerous “old coal pits” showing the importance of coal mining in the area pre 1848
Report 15079 Page 3
The 1893 1:2500 map shows the area heavily industrialised with Bankhouse Iron Works to the
south east, StoneyHolmes Gas Works to the south, Calder Vale Works to the south and
StoneyHolme Shed (cotton works) on the immediate southern boundary. The study area is
occupied by back to back terraced housing.
The 1912 map shows that ne terraced housing has been built above the River Calder to the rear of
Abbey Street.
Report 15079 Page 4
The 1931 map shows the intensive terraced housing of the study area. The river bank of the Calder
seems to have been modified to smooth out the course of the river.
There are no changes shown on the mapping. The 1970 map shows the static arrangement of
housing and factory. The river bank has been engineered with a masonry surfacing
Report 15079 Page 5
The 1982 map shows that the terraced housing has been cleared and the StoneyHolme Shed has
been redeveloped. The old cotton shed is now the “Refuse Destructor”
There are no changes on the site shown on the mapping up to 1997.
Report 15079 Page 6
4. SITE GEOLOGY
The published British Geological Survey (BGS) 1:50000 map for Clitheroe Sheet Number 68 shows
the site is underlain by:
• Drift geology of Recent Alluvium of the River Calder to the western boundary of the site and
Glacial Till (Boulder Clay) below and to the east of the site.
• The bedrock is shows as Pennine Lower Coal Measures Formation - mudstone, siltstone
and sandstone. The map shows that the Burnley Four Feet coal seam to subcrop across
the north west corner of the site with a tend of approximately north south and dipping under
the site. The map shows the local dip of the bedrock to be 5° to the south east.
5. COAL AUTHORITY MINING REPORT
A Coal Authority report was received by Burnley Borough Council, dated 12th February 2010. The
report states:
• The property is in the likely zone of influence from workings in 2 seams of coal at 60m to
290m depth, and last worked in 1959.
• Any ground movement from these coal workings should have stopped by now.
• In addition the property is in an area where the Coal Authority believe there is coal at or
close to the surface. This coal may have been worked at some time in the past.
• There are no known coal mine entries within, or within 20 metres of, the boundary of the
property.
• Records may be incomplete. Consequently, there may exist in the local area mine entries of
which the Coal Authority has no knowledge.
Report 15079 Page 7
6. FIELDWORK
The fieldwork comprised three stages.
1) Machines excavated trial pits, 11 No, undertaken on 2nd and 3rd March 2011
2) Light cable percussion (shell and auger) 150mm diameter boreholes undertaken between 2nd
March 2011 and 25th March 2011.Completed to depths varying between 9.235m and18.185m
below the existing ground surface level using shell, clay cutter and light cable percussion
techniques. A CAT services screen was undertaken followed by a hand excavated services pit
for each borehole prior to the commencement of the borehole.
3) Rotary boreholes were drilled using Open hole/ODEX Casing drilling techniques. Air flush was
used with the boreholes taking groundwater within the bedrock. BHR6 was cancelled due to the
excessive groundwater issuing as noted in previous boreholes.

Report 15079 Page 8
Undisturbed 100mm diameter samples were taken in the cohesive strata1(OS-T/W(100mm with
liner). Standard penetration tests were carried out, in accordance with BS EN ISO 22476-3:2005
(formerly BS 1377 Part 9:1990), in the granular strata and in the cohesive strata, which were too
hard to sample by the 100mm diameter method and to prove bedrock. Selected disturbed samples
and bulk samples were also taken and together with the undisturbed samples and samples from the
standard penetration tests returned to our laboratory for inspection and testing as appropriate.
Groundwater samples were obtained where ground conditions allowed.
Detailed results of the strata met, depths and levels of changes, thickness of strata, samples taken,
groundwater observations and standard penetration test (SPT) N values are given on the Light
Cable Percussion borehole record sheets in Appendix 2.1. The detailed results of the Standard
Penetration Test (SPT) are presented in the table in Appendix 2.2. The records of the Rotary Open
Hole boreholes are presented in Appendix 2.3. The records of the Machine Excavated trial Pits with
record photographs are presented in Appendix 2.4.
The positions of the boreholes are given on the Borehole Location Plan in Appendix 4.
A Site Location Plan is given in Appendix 5.

8. SUMMARY OF GROUND CONDITIONS
The Light Cable Percussion boreholes show the following sequence of strata.
Topsoil Generally thin 0.1-0.3m brown clayey and sandy, some
contamination with brick fragments.
Made Ground Generally summarised and demolition spoil (uncontrolled) with
areas of infilled cellars to the historic housing.
The Made Ground is a mix of brick rubble slate, wood plaster,
sandstone flags old cast iron drainage pipe, pottery with sand and
occasional plastic.
The old road surfacing of gritstone setts was found in TP6,TP7 and
TP8.
The thickness of the Made Ground ranges from 0.9 -2.0m plus in
the trial pits and from 2.2m to 2.4m in the Light Cable Percussion
boreholes.
Alluvial Sand Directly underlying the Made Ground in BH1 only. Present from
2.4m comprising loose becoming medium dense brown silty slightly
clay fine and fine-medium grained Sand. With depth there is
variable gravel content. The N value ranges from 6 at 3.0m to 24 at
2.0m.
Alluvial Clay and Silt. In BH4 from2.3m to 7.3m is a soft and very soft gravelly sandy
Clay. The cu is 36kN/m2 at 2.10m and 17kN/m2 at 3.2m. between
3.7m and 4.2m is a band of loose slightly silty fine-coarse sand and
fine-medium gravel.
Below 4.2m is loose (SPTN 6-9) brown/grey clayey slightly gravelly
fine sandy Silt.
In BH6 from 2.2-3.7m soft and very soft fine-medium sandy fine-
medium gravelly with a thick 0.8m band of medium dense fine-
coarse grained sand and fine-medium Gravel with occasional
cobble
Glacial Sand and Gravel In BH1 from 5.0m the Alluvial Sand grades into a Medium dense
and dense fine-coarse gravelly fine-medium grained Sand. The N
value at 6.0m was 31 and at 6.7m 18.
In BH2 from 5.9-7.7m, below the Glacial Clay are loose grey clayey
fine-medium Sand and grey clayey fine-medium sandy fine-coarse
angular and subangular Gravel. The N value is 70 and 75
In BH4 from 7.3m to 13.5m the grey slightly clayey fine-medium
sandy fine-coarse Gravel with occasional cobbles. Increasing
mudstone content with depth.
Report 15079 Page 11
SPTN in the range 26-94.
BH5 from 7.6-9.10m and from 13.0m to 16.7m below the Glacial
Clay are thick horizons of very dense fine-coarse Sand and fine-

9. GEOTECHNICAL ASSESSMENT
Foundation Assessment
No details of the proposed development or the proposed development elevation.
The site was formerly occupied by terraced housing that dates back to the late 19th Century. The
terraced housing was demolished some time in the 1980s.
The investigation has shown that the street surfacing (gritstone setts) remain in place and that
some of the old houses had cellars and these have been infilled with the demolition material.
Underlying the Made Ground the natural geology comprises Recent Alluvium, a very weak
sequence of very soft and soft sandy gravelly Clay and loose clayey silty gravelly Sand that can be
attributed to the course of the river Calder and the remainder of the site is underlain by Glacial Till
(Boulder Clay). The Glacial Till is both firm and stiff-very stiff sandy gravelly Clay and medium
dense and dense Sand and Gravel.
We would consider that the nature and variability of the natural shallow soils will generally preclude
the use of a conventional spread foundation. Therefore we consider that there are two main options
for foundations on this site.
1) Piled foundations. End bearing piles taken through the Alluvium and Glacial Till to reach
the weathered mudstone, where shallow. In the areas where the mudstone is deeper a
piled foundation using both end bearing and shaft adhesion.
2) Vibro-consolidation. The weaker soils and deeper Made Ground would be consolidated
and the ground strengthened with stone columns. The nature of the weaker Alluvial soils
and the proximity of the engineered course of the River Calder will require careful design
assessment to avoid damaging the river bank.
As discussed above the whole area has been reclaimed after the demolition of the old terraced
houses including the infilling of cellars with the demolition spoil. Any new access roads will require
to adopt a full capping layer in the design.
The trial pits showed that there is no perched groundwater and in the boreholes groundwater was
only encountered as a water strike in boreholes along the river side at a depth of BH1 7.9m and
BH4 8.0m.
Mining Related Issues
Detail of the ground conditions encountered in the bedrock, are given on the borehole record sheets
and summarised above.
Report 15079 Page 15
The geological map shows that the Burnley Four Foot Coal Seam could dip under the site at
shallow bedding of 5° to the south east.
No open voids were encountered in any of the boreholes. BH1Rand BH5R were the only two
completed to design depth (40m). Coal was encountered in BH1R 15.5-16.0m, BH4R 18.1-18.8m
and 26.1-26.6m BH5R 26.4-26.8m. The maximum coal seam thickness penetrated was 0.5m and
does reach the 1.2m of the Burnley Four Foot.
Weakened and broken ground was encountered in all of the boreholes which could indicate that
there has been mining of the thicker coal. In BH2R the fast penetration was between 15.6-21.2m
and the borehole was collapsing from 22m. In BH3R the weakened ground was between 19.7m and
20.1m with the borehole collapsing around the drill. In BH4R the weakened ground was below the
Coal from 19.9m to 20.9m, at 25m the drill encountered a high groundwater inflow that precluded
further drilling.
As noted above there were no open voids that would be attributed to coal mining but there is
evidence of broken ground. If the site is to be piled it is possible that pile penetration could come
into the zone where there is weakened mudstone.
We would consider it prudent to consider adopting a zoned grouting programme prior to any piled
foundation works.
If the ground improvement foundation solution option was chosen then we would consider that there
will be no requirement to consolidate the weakened bedrock.
Concrete in Aggressive Ground
With reference to BRE Special Digest 1 the site should be considered as brownfield with mobile
groundwater.
The testing for sulphates shows moderate concentration of soluble sulfate in the Made Ground and
low-moderate sulfate content in the ground water.
Therefore the Site Design Sulphate Class is DS1 and the Aggressive Chemical Environment for
Concrete (ACEC) is AC1s.
Report 15079 Page 16
10. CONTAMINATION ASSESSMENT
CONTAMINATED SOIL
The current legislation for the assessment of Contaminated Land is Part IIA of the Environmental
Protection Act (1990) Contaminated Land Regime and the development controls of the relevant
Town and Country Planning acts. EA/DEFRA has produced four reports and assessment software
to assist in the assessment of the potential harmful effects of contaminated land to the users of the
land and the risk to the general environment. The EA/DEFRA has withdrawn all published SGV
(Soil Guidance Values) for certain target compounds and contaminants and these are used for a
Generic Risk Assessment. Updated TOX reports have been issued.
For assessment of the results of contamination tests we make reference to the Atrisksoil©
commercial database for Generic Assessment Criteria (GAC). Atkins have derived ATRISKSOIL©
SSVs based on the 2009 SC050021/SR3 “Updated background to the CLEA model and
SC050021/SR2 (the TOX report) for commercial/industrial, residential without plant uptake and
residential with plant uptake. We have based these on the default assumptions provided in the
CLEA report which we understand will be used in development of the Soil Guideline Values by
Defra and the Environment Agency.
In the assessment of the results of testing comparisons to publish Generic Assessment Criteria
from EA published SGV (Soil Guidance Value) for certain target compounds and the Atkins
AtriskSoil© database of Generic Assessment Criteria’s (GAC).
SGVs represent ‘intervention values’; and provide indication that soil concentrations above this level might represent an
unacceptable potential risk to the health of site-users, depending on land-use and that further investigation and possibly
remediation is required (copper and zinc are known to be phytotoxic in nature and not covered under CLEA).
Atkins has developed Soil Screening Values (SSVs) applicable to the UK for common contaminants not currently covered by
SGVs issued by Defra and the Environment Agency. Full justification is provided to support their use.
The disposal of construction spoil that is considered waste will need to be assessed in line with
current Land Fill regulations. The Landfill (England and Wales) (Amendment) Regulations 2004
have introduced a set of analysis requirements for the classification of waste into
• Inert Waste
• Non-reactive hazardous Waste
• Hazardous Waste.
If excavation spoil is to be taken off site for disposal additional testing for the Waste Acceptance
Criteria will be required.
This investigation of contaminated soil must only be considered as the preliminary phase of works
where there is an identified contamination hazard. The results of the analyses of a sample can only
be relied on as evidence as to what is in the sample and not what may be in the surrounding or
adjacent area. Additional works may be necessary to assess the hazard of any contamination on
Report 15079 Page 17
site and the local environmental impact. Additional investigation may be necessary to evaluate the
extent and hence volume of any contaminated soil. The assessment of the contaminated soil must
take account of the limited access as part of the of the contamination investigation.
As noted above no detailed design has been seen from which the risk model can be selected. For
preliminary assessment purposes we have adopted the most conservative risk model of residential
with home-grown vegetables. If the EPP development will result in predominantly hard landscaped
areas with greenspace for association only then a more appropriate risk model can be assessed.
The site was been developed from open land, adjacent to a large cotton mill, in the late 1800s. The
terraced housing was demolished in the 1980s and has remained as open space since.
No Asbestos Fibres were visually identified in the soil samples analysed.

site and the local environmental impact. Additional investigation may be necessary to evaluate the
extent and hence volume of any contaminated soil. The assessment of the contaminated soil must
take account of the limited access as part of the of the contamination investigation.
As noted above no detailed design has been seen from which the risk model can be selected. For
preliminary assessment purposes we have adopted the most conservative risk model of residential
with home-grown vegetables. If the EPP development will result in predominantly hard landscaped
areas with greenspace for association only then a more appropriate risk model can be assessed.
The site was been developed from open land, adjacent to a large cotton mill, in the late 1800s. The
terraced housing was demolished in the 1980s and has remained as open space since.
No Asbestos Fibres were visually identified in the soil samples analysed.

It can be seen that there are elevated Poly-Aromatic Hydrocarbons (PAH) in some samples, with
the most likely source of the Poly-Aromatic Hydrocarbons (PAH)’s coming from coal ashes and
cinders in the demolition fill.
However, soil samples when inspected in the laboratory have been identified as having a
hydrocarbon odour. This may be from spilt hydrocarbon fuels, tar used for road and pavement
construction or from spent tar. A sample from BH1 at 2.0m showed a particular observable odour

CONCLUSIONS
The site has been assessed using a conservative Risk Model of Residential. Depending on the final
design for the proposed end use a less stringent risk model may be appropriate.
The investigation has confirmed that the site of the former terraced housing was demolished and a
significant proportion of the demolition spoil has been left on site, probably used to up-fill the cellars
of the old properties. At BH1 and BH4 there is deep Made Ground that may represent the fill placed
when the River Calder course was engineered and lined with stone pitching.
The tests have shown that the principal contaminants are Arsenic (maximum concentration
54mg/kg) and Lead (maximum concentration 900mg/kg). These concentrations exceed the Parks
Risk Model but not Commercial / Open Space / Playing Fields.
Report 15079 Page 20
To mitigate the effects of contamination an Engineered Cover System can be adopted. The
Engineered Cover System comprises a system to break the pathway of Receptor and Source and
to allow dilution from soil mixing. An ECS would have a total thickness of between 450mm and
600mm.

Terminology Used in Soil Descriptions
The procedure and principles given in BS EN ISO 14688 part 1 & 2 and the amended BS 5930 (1999) Revision Section 6 in accordance to have beenadopted in producing the soils description contained in this report.A soil’s characteristics are based on the particle size grading of the coarser particles and the plasticity of the finer particles. The classification is thereforebased on the following.While describing a soil the main characteristics should be preferably stated in a standard word order, however the word order can be adjusted if required forclarity.
a) Mass characteristics b) Material characteristics c) Stratum Name
1a) Relative density / consistency 1b) Colour1c) Geological formations, age and type ofdeposit where possible
2a) Discontinuities2b) Particle shape, size grading andcomposition.
3a) Bedding3b) Soil name (capital e.g. SAND),based ongrading and plasticity.

Relative density of sands and gravel may only be determined by the standard penetration test scale in terms of N-Values, however it should not be used forvery coarse soils. The use of empirical relationships between standard penetration test ‘N’ values and strength of fine soils may also be useful but should notbe used to provide strength descriptors on field records.An undrained strength can be given on the field record when measurement of the undrained shear strength is made in the field by hand vane or in thelaboratory by triaxial test.Silts depending on their grading, may behave either as a coarse soil or fine soil; consistency term ( density/strength) shall be used accordingly.
Description of Discontinuities and Beddding.
When describing discontinuities the type should be stated e.g. fissures, faults, shear planes and the spacing detailed as below. Their persistence, opennessand surface texture (e.g. rough, smooth, polished, striated) should be described and where possible orientation and trend should be stated.

Terminology Used in Soil Descriptions - cont.Material Characteristics of Soils.
Material characteristics refer to those characteristics that can be described from visual and mutual examination of disturbed or undisturbed samples.Characteristics include colour, particle shape, particle grading and particle composition.ColourColour given should be an overall impression. Colour differences can be emphasised separately by the use of terms such as spotted, mottled, streaked ormulti-coloured. Details of colours are given below:-Tertiary descriptor- Light / DarkSecondary descriptor- Pinkish, reddish, yellowish, orangish, brownish, greenish, bluish, greyishPrimary descriptor- Pink, red, yellow, orange, brown, green, blue, white, grey, black(Changes due to oxidization, desiccation for example should be noted.)
Particle Shape:- The recommended terms to describe particle shape of gravel size or larger particles are as followsAngularity Form Surface texture.
Very- angularAngular Flat / Tubular rough
Sub-angular elongated smoothSub-rounded cubic
Rounded
The surfaces of the particles may bedescribed for example as etched,pitted, honeycombed or polished
Well roundedParticle Grading:-Coarse: The distribution of particle sizes within sands and gravel should be described stating predominant size fraction present e.g. fine tomedium SAND. Subangular elongated smooth fine gravel. Absence of these adjectives means that they are all present in roughly equal proportion.Very Coarse: The proportion of cobbles in a boulder deposit (or visa-versa) may be quantified using the terms with a little, with some, or with much; verycoarse soils with secondary finer material (coarse and fine soil) should be described likewise e.g. COBBLES with much sandy CLAY.
Finer material (coarse and fine soil) with very coarse secondary fraction should be described as followsFraction Percentage by mass Term
Boulders< 5
5 to 20> 20
Low boulder contentMedium boulder content
High boulder content
Cobbles< 10
10 to 20> 20
Low boulder contentMedium boulder content
High boulder contentIt is recommended that the dominant secondary fraction comes immediately before the principal soil term. To avoid ambiguity, if any of the constituent sizes
require qualifying adjectives, these should be added in separate sentences after the main description; such as the estimated percentage proportion orconsistency,
e.g.’’ Gravelly very clayey SAND. Gravel (10%) is fine of rounded quartz. Clay is firm’’.Principal Soil Type and Secondary Constituents.The soil name is based on particle size of the coarse fraction and/or the plasticity of the fine fractionThe basic soil types and their subdivisions are defined by the range of their particle sizes as shown.

The description of plasticity may be carried out using terms providedin BS EN ISO14688-1 2002
The description of ‘finer material’ is made ignoring the very coarse fraction; descriptions with cumulative proportions of various fractions, excluding cobblesand boulders, exceeding 100% are incorrect.
Coarse soils:-
Very coarse soils:-
For mixtures involving very coarse soils, the principal soil type name in the fine material may also be given in capital letters, e.g. COBBLES with some sandyCLAY
The location of individual cobbles and boulders should be noted on the logs. The term large boulder does not have an upper size limit, so dimension shouldbe stated wherever available.
Minor constituents: where soil contain minor quantities (less than about 10% in fine soil and 1% coarse) which are relevant to geology can be included beforethe principal soil type using ‘slightly micaceous’ or ‘very shelly’ or at the end of description using qualitative terms such as ‘rare’, ‘ occasional’ or ‘frequent’,e.g.’SAND with rare gravel size brick fragments’.
Man-made soils: are the soils which are placed by man and can be divided into those composed of reworked natural soils and those composed of man-madematerials. ‘Fill’ is placed in controlled manner, and ‘made ground’ is placed without strict engineering control. Description of such soils should includefollowing
.
a) Origin of the materialb) Presence of large objects e.g. concrete,
mortar etcc) Presence of voids/ collapsible hollow
objectsd) Chemical waste and hazardous
substancese) Organic matter f) Odours smell
g) Striking colour tints h) Any dates readable on buried papers etc.i) Signs of heat or combustion under ground
e.g steam emerging from boreholej) Structure, variability and mention of
placement.

Page 1 – The Standard Penetration Test
���������&������������� �
The full procedure of carrying out the Standard Penetration Tests (SPT) is given in BS 1377:1990 : Methods of Testsfor Soils and Civil Engineering Purposes Test 9:3.
Essentially the tests consists of driving a 50mm external diameter split barrel sampler into the soil using a 65kg hammer dropping760mm. The penetration resistance is expressed as the number of blows required to obtain 300mm penetration (test drive)below a seating drive of 150mm through any disturbed ground at the bottom of the borehole.
The number of blows for the 300mm test drive penetration is recorded on the borehole logs as the N - value.A full record of the number of blows required to drive the sample at 75mm intervals throughout the total 450mm drive is alsotabulated along with the groundwater levels at the time of test.
The test is normally performed on sands, but may also be used in gravels, weak rocks and glacial tills in which case the drivingshoe may be replaced by a cone. When attempting the standard penetration tests in very dense materials or weathered bedrockit may be necessary to terminate the test before completion to prevent damage to the equipment.
In these circumstances it is important to distinguish how the blow count relates to the penetration of the sampler.This may be achieved in the following manner:
a) Seating Drive - using standard blows the seating drive is apenetration of 150mm or 25 blows whichever is first reached
b) Test Drive - the number of blows required for a furtherpenetration of 300mm. If 300mm cannot be achieved in 50blows the test can be terminated Record the number of blowsper 75mm for both seating and test drives. If either theseating drive or the test drive is terminated before fullpenetration record the depth of penetration for the 25 blowsor 50 blows respectively
c) In soft rock the test drive should be terminated after 100blows if a penetration of 300mm has not been achieved
The N - value obtained from the Standard Penetration Tests may be used to assess the relative density of sands andgravels in accordance with Clause 41.3.2 of BS 5930:1999 : Code of Practice for Site Investigation as follows:
�����&��$�/�7���� �.����( �)**��
&����������
Very Loose 0 - 4
Loose 4 - 10
Medium Dense 10 - 30
Dense 30 - 50
Very Dense Over 50
In soft strata when the sampler assembly is lowered to the bottom of the borehole on the drive rods with the drive assembly ontop the sampler may penetrate under self-weight. This initial penetration should be measured and recorded. If the initialpenetration exceeds 450mm omit the seating and test drives and report the N value as zero.

Table 1, Page 22 gives details of the equipment used for the two test methods, i.e. DPH (dynamic probing heavy) and DPSH(dynamic probing super heavy). The DPSH method equates to the Standard Penetration Test (SPT) and the DPH is theconventional dynamic probe test (DPT).
The test method requires the recording of the blows required to drive the 90º cones and driving rods into the soil over an intervalof 100 mm. At the end of each 1.0m rod the torque resistance of the rod shall be measured and recorded.

Durability of Concrete in Aggressive Ground and Groundwater Conditions
Reference should be made to BRE Special Digest 1: 2005 for the detailed assessment of the potential forSulfate and Acid attack on concrete.Figures C4 C5 and C6 give the procedure for assessing the Aggressive Chemical Environment (ACEC)based on the nature of the site and the potential hazards on the site.Sites are “greenfield without pyritic soil”, “greenfield with pyritic soil”, “brownfield without pyritic soil” and“brownfield with pyritic soil”. Thus suitable samples of soil and groundwater should be selected for analysesof Soluble Sulfate (2:1 water soil extract) and pH (1:2.5 water soil extract).The table extracts below give the relevant information from the document.

RECORD SHEET SYMBOL KEY
SAMPLES/TESTS U Undisturbed 100mm open tube driven sample (depth records recovered length from start of test).
OS-T/W(100mm with liner) * Indicates a sample with Nil Recovery {x.xx} indicates the water at the sample depth.
D Small disturbed sample (depth records the interval of sample). ES EW Environmental samples (SOIL/WATER). Small disturbed samples for contamination analysis
comprising glass and plastic tubs. B Large disturbed sample (Bulk) depth records recorded interval. S Standard penetration test (SPT; BS EN ISO 22476-3) recovered as a small disturbed sample.
* Indicates a sample with Nil Recovery. {x.xx} indicates the water at the sample depth.
C Solid Cone Penetration test, in rock and coarse granular soils. W Water sample. L Continuous Dynamic Sample 84mm 1.0m long
FIELD RECORD COLUMN This column is used to present depth related information of site activity. The column will always show progress, details of water strikes and rises, field records of the SPT test and the Undisturbed sample blows. Other data may be present in this column and details of codes will be given in the remarks box at the bottom of the record sheet page.
Water Level Codes
M1 2.00 Water strike (with sequential number of the strike) recorded depth. T1 1.90 Temporary rest level after 20 minutes with recorded depth.
Progress Codes
-{07/08/2002}-Records the date at the depth of the borehole when the borehole takes more than one day to complete. Also indicated on completion. Recorded for start of second day and subsequent shifts.
(TSL 3.00m) Represents the water rest level at the start of the shift (AM) or the end of the borehole shown with the date of observation.
Field Records
1,2-3,4,5,6 Detailed SPT records for each 75mm test interval (incomplete penetration tests will be recorded showing blows for measured penetration).
[U60] U100 open tube sampler blows to drive the sampler the full length
ROTARY CORE DRILLING RECORDS
Details of the rock fracture state are given in the Mechanical Log portion of the sheet SCR TCR and RQD are described in BS EN ISO 22475-1 (and BS 5930 Section 44.4.4) If is average fracture spacing over a particular lithology, Where the core is fully broken 0 indicates Non-Intact
MONITORING INSTALLATIONS
Standpipe piezometer or groundwater monitoring wells and water level information may be shown on the standard record sheet or a separate installation sheet. Bentonite seals, filter zones and installation depths are indicated. Details of installation are given in the report.
Legend symbols are those given BS5930:1999 (ISO 710-1-7) but for clarity may only the show major constituent.
Strata descriptions are compiled by visual examination of samples obtained during boring, after BS EN 14689-1:2003 and BS EN ISO 14689-1:2003: Geotechnical investigation and testing. Identification and classification of
rock. Identification and description. Laboratory test results where applicable.
