1 Introduction

1.1 General Introduction

Following the measurement of elevated concentrations of chlorinated solvents in

borehole location BHXX3 which is very close to the secant wall which encloses the

long piles at Pier 1 (P1) it was decided that additional investigation to investigate the

potential for chlorinated solvents (at concentrations approaching saturation (i.e.

presence of DNAPL) was required within the secant wall.

This document presents a conceptual site model (CSM) that specifically relates only to

Pier P1 on the North Approach Viaduct (NAV)of the Mersey Gateway Bridge Project.

The CSM will characterise the chemical concentrations within the P1 secant wall and if

significant risks are identified (i.e. the potential presence of DNAPL which may migrate

down the shaft of the long piles) will be used to inform a remedial options appraisal

(ROA).

The objective of the P1 CSM report is not to assess if the construction works have had

an impact on concentrations of contaminants in groundwater in the area of the P1

structure. This type of assessment and discussion would be undertaken outwith the

CSM and PRA documents and in accordance with the mechanisms set out in the

WQMP. However, to allow comparison of the data to that of the works being

undertaken at P1, a time scale of the works including the installation of the secant wall

piling is provided within Appendix E. A brief summary of the piling activity is included

below for reference:

Piling at P1 time scale summary:

• 22nd January 2015 – 3rd February 2015: Installation of Cofferdams (CFA

Piling);

• 20th February 2015 – 10th March 2015: Bored Piling (Piles 1-6);

• 9th September 2015 - 27th September 2015: MSS Support (Cofferdam CFA

piling); and

• 17th September 2015 - 27th September 2015: MSS Support (Bored piling).



The ROA will assess the options and the best overall approach to remediate the soil

and groundwater contained within the secant pile cut-off wall surrounding the existing

P1 piles, where elevated levels of chemicals of potential concern (COPC) have been

identified, to minimise potential risks to the underlying principal aquifer (Sandstone

bedrock). The COPC are predominantly chlorinated solvents including carbon

tetrachloride and chloroform.

1.2 Background

The secant wall was constructed (as recommended in the Piling Risk Assessment

(PRA) report (MER-DJV-REP-ENV-03-333007_REV9, October 2015) at P1 prior to

the commencement of the piling activities and its design was two-fold:

1. To form a barrier and prevent the migration of elevated concentrations of

COPC inflowing to the P1 structure via groundwater within the granular alluvial

deposits from sources of contamination identified during earlier phases of the

project to the north and west. This barrier extended into the top of the

underlying low permeability glacial clay deposits; and

2. To facilitate the planned construction of the pile cap for which a ‘dry’ dewatered

excavation is required.

Four boreholes BHXX1, BHXX2, BHXX4 and BHXX5 were drilled and installed with

monitoring wells within the secant pile cut-off wall at the P1 structure between

September 2014 and April 2015. Borehole BHXX3, which is located just a few metres

immediately to the north of the secant pile cut-off wall, is also assessed in order to

make a direct comparison between COPC concentrations inside the wall with those

immediately outside of the wall. BHXX3 is the closest borehole to P1 beyond the

secant wall boundary. As this report focuses on ground conditions specifically in the

area inside the secant wall, only BHXX1-BHXX5 have been assessed in this CSM.

Information concerning the CSM of the wider area surrounding P1, is presented in

North Abutment (N1) to Pier P10 Conceptual Site Model Report (Ref. MER-DJV-REP-

ENV-03-333032 Rev 0, August 2015)

It was not possible to undertake ground investigations directly within the P1 footprint in

the early phases of the project due to this area being under water (previously the area

was part of the St Helens Canal). During later phases of groundwater investigation

works (after this section of the St Helens Canal was infilled to form a temporary road /

reclaimed land), BHXX1, BHXX2 and BHXX3 were completed in October 2014, and



BHXX4 and BHXX5 were completed in April 2015. The borehole location plan centred

on the P1 structure is shown on Figure 1. Photographs showing the Pier 1 site area

are presented in Appendix A.

Soil and groundwater sampling were undertaken at each of the locations between the

end of September 2014 and early May 2015. Elevated concentrations of COPC,

specifically carbon tetrachloride, have intermittently exceeded 15,000µg/l in

groundwater from BHXX3 relating to the shallow alluvial deposits. This led to a more

focussed CSM in the area of P1 being developed to better understand the distribution

of elevated concentrations of COPC, in particular chlorinated solvents, which have

also been detected in groundwater samples taken from some of the monitoring wells

(BHXX1, BHXX4 and BHXX5) located within the secant pile cut-off wall surrounding

the P1 structure. The development of the CSM takes account of and makes reference

to the PRA.



2 Geology

2.1 Introduction

The geology is shown on schematic cross sections which bisect P1 from North to

South and from East to West and are presented as Figure 2. The “BHXX” series

borehole logs are presented in Appendix B.

In summary, the geological sequence within the P1 structure comprises Made Ground,

Alluvial Deposits, Glacial Deposits and Sherwood Sandstone bedrock, as outlined

below.

2.2 Made Ground

Made Ground was encountered ranging in thickness from 3.5 to 4.6m. Made Ground

was described as ‘road stone’ in BHXX1 and predominantly comprised limestone

gravel (temporary fill material). The composition of Made Ground was similar at the

other borehole locations.

2.3 Alluvial Deposits

The alluvial deposits ranged in thickness from 5.7 to 6.5m and extended to a generally

uniform depth of 10.2m bgl corresponding to an elevation of -2.2m AOD. Note that the

secant wall extends approximately 0.3m below the base of the alluvium into the top of

the glacial clays at a depth of approximately 10.5m bgl (-2.5m AOD) in order to form

an effective barrier to groundwater flow within the permeable alluvial deposits.

The alluvium can be divided into an upper cohesive layer and lower granular layer.

The relatively thin upper cohesive layer is represented by predominantly firm sandy

clay between 0.2 and 2.0m in thickness, and is underlain by a granular layer

consisting of fine to coarse sands of greater thickness (4.5 and 5.6m).

Boreholes BHXX3, BHXX4 and BHXX5 terminated at the base of the alluvium.

2.4 Glacial Deposits

Within the deeper boreholes (BHXX1 and BHXX2), glacial deposits comprising inter-

bedded layers of gravelly clays and sands were encountered as shown on the

geological cross sections. The glacial deposits extended to a depth of 43.9m bgl in

BHXX2.



The glacial deposits can be divided into an upper cohesive layer of gravelly clay

(approximately 2.5m to 3.0m in thickness), overlying a predominantly granular layer of

sand with gravelly clay lenses (approximately 5.0m to 6.0m in thickness), which in turn

overlies cohesive gravelly clay.

2.5 Sandstone

Depth to bedrock (Sherwood Sandstone) was proven in BHXX2 and was encountered

at 43.9m bgl. The borehole log described the solid geology as thin to thick laminations

of reddish brown fine to medium-grained sandstone. BHXX2 extended to a maximum

depth of 53.8m bgl.



3 Hydrogeology

3.1 Introduction

Each of the four boreholes within the P1 structure was installed as monitoring wells

which screen the encountered strata (alluvial deposits, glacial sands and sandstone)

as follows:

• BHXX4 and BHXX5 both screen the shallow groundwater body associated with

the sandy alluvial deposits (7.5 to 10.7m bgl) with a screen length of 3.2m.

• BHXX1 has a 1m screen interval against the glacial sand deposits (17.7 to

18.7m bgl)

• BHXX2 has a 10.0m screened section against the deep sandstone bedrock

aquifer (43.8 to 53.8m bgl).

Outside of the P1 structure, BHXX3 was screened across the shallow groundwater

body associated with the sandy alluvial deposits (8.5 to 11.5m bgl) with a screen

length of approximately 3.0m.

3.2 Groundwater Strikes

Within the P1 structure a groundwater strike was encountered in just one of the

boreholes, BHXX4, at 3.2m bgl in the made ground, with groundwater rising to 3.0m

bgl over a 20 minute period.

A groundwater strike was also recorded in the BHXX3 (beyond the secant wall) at

5.7m bgl at the interface between the upper cohesive alluvial clays and the underlying

alluvial sands, rising to 4.7m bgl after a period of 20 minutes.

3.3 Groundwater Elevations

The depth to groundwater measurements and corresponding groundwater elevations

are presented in Table 1 for BHXX1 to BHXX5 and summarised below. BHXX3 was

originally part of the wider groundwater monitoring network (decommissioned/ grouted

in August 2015), while the four monitoring wells within the P1 structure were destroyed

within one month of their installation as a result of construction activities. As such, a

more comprehensive dataset of groundwater levels is available for BHXX3 from

November 2014 to May 2015, while limited datasets are available for BHXX1 and



BHXX2 (relating to November 2014), and groundwater levels were recorded on two

occasions (29th April 2015 and 5th May 2015) at BHXX4 and BHXX5.

A review of groundwater elevations relating to the different strata are presented in the

sections below.

3.3.1 Alluvial Deposits

Three monitoring wells, BHXX3, BHXX4 and BHXX5 screen the alluvial deposits.

BHXX3 is located outside of the secant wall and inferred up hydraulic gradient of

BHXX4 and BHXX5, located inside the secant wall structure.

The depth to groundwater was measured at all three locations on the 29th April 2015

(prior to the well development of BHXX4 and BHXX5) and levels ranged from 3.70 to

3.95 m below top of casing (btoc). The corresponding groundwater elevations fit the

general trend in groundwater flow with groundwater elevation of 4.55m AOD at

BHXX3 decreasing to 4.30m AOD and 4.07m AOD at BHXX4 and BHXX5,

respectively.

On the following monitoring event (5th May 2015), this trend was not observed. The

groundwater elevation at BHXX3 rose very slightly by 0.17m to 4.72m AOD, while

within the secant wall groundwater levels rose by between 1.0 and 1.3m in BHXX4

and BHXX5 to 5.25m AOD and 5.35m AOD, respectively. It is notable that the

groundwater level within the secant wall is much higher than externally and therefore

is considered to be hydraulically isolated.

Given that the purpose of the secant wall is to act as a barrier and prevent the

movement of groundwater into and from the area within the structure, it is likely to act

as a ‘sealed bucket’ resulting in the input of waters within the secant wall artificially

raising groundwater elevations within P1. The downward infiltration of groundwater

into the underlying strata will be limited by the low permeability layer of glacial clay

deposits at the base of the alluvium.

Unfortunately, BHXX4 and BHXX5 are no longer in the groundwater monitoring

network, having been destroyed by construction activities (notably their installation

was never intended to be permanent) so it is not possible to assess this further.

However, this groundwater elevation data does suggest that the secant wall is working

as an effective groundwater flow barrier.



It is proposed that the greater rise in groundwater levels within the secant wall to that

outside on the 5th May 2015 and the potential for a linkage between the wider groundwater

outside of the secant wall and that within, be explored, including the potential for construction

activities at the site having had an effect on groundwater levels. This investigation

should be undertaken as part of the remediation works, verification of the remediation works,

or in the verification of the construction activities at P1 in line with the mechanisms set out

within the WQMP.

3.3.2 Glacial Sands

Groundwater level monitoring data for BHXX1 representing the deeper glacial sands

unit were collected in November 2014 and groundwater elevations (potentiometric

surface) of between 2.04 and 2.09 m AOD were measured on three occasions.

Measured groundwater levels in the glacial sands are approximately 2m lower than

those measured in the overlying Alluvium (on 30 April 2015) and indicate that the

intervening Glacial Clay layer acts as a good hydraulic barrier to groundwater flow.

The Glacial Sands are also known to be tidally influenced (refer to REP-ENV-03-

333032 Rev 0, August 2015) which could explain the lower heads measured within

this unit and highlight that they have a good permeability (compared to other horizons)

and a good connection to groundwater discharge zones (ultimately the River Mersey).

3.3.3 Sandstone

Within P1, only one monitoring well, BHXX2, was advanced to the deep sandstone

bedrock that was encountered at 43.9m bgl. Three rounds of groundwater level

monitoring were undertaken in November 2014 and the potentiometric surface was

between 4.05 to 4.19m AOD.

The groundwater elevation (potentiometric surface) associated with the sandstone

bedrock is approximately 2m higher than those measured in the overlying glacial sand

deposits. This is expected due to the depth of the sandstone and it being confined by

substantial thickness of low permeable glacial clay deposits. .

3.4 Groundwater Flow Direction

Based on data collected from previous ground investigations (see PRA), the regional

groundwater flow direction within the sandstone bedrock is inferred towards the south



east. The groundwater flow direction within the glacial sands and alluvial deposits in

the vicinity of the P1 structure is less well understood (due to the lack of monitoring

wells in the area which screen the same groundwater unit). The groundwater body

within the alluvial deposits (with potentiometric surface at approximately 5m bgl) could

be influenced by shallow groundwater migration from within the made ground where

cohesive alluvium between the two strata is limited or not present. In addition there is

known to be some tidal influence on groundwater flow (MER-DJV-REP-ENV-03-

333007_REV9, October 2015).

The construction of the secant wall structure also is anticipated to have an impact on

the groundwater flow behaviour within the alluvial deposits. First of all, groundwater

level monitoring data suggests that rainfall-recharge could be causing an artificial rise

in groundwater within the secant wall. Secondly, there is unlikely to be any change in

hydraulic gradient (i.e. will remain flat) inside the confines of the secant wall, as the

groundwater flow path has been severed. The piezometric head should be

maintained at a level below the blinding concrete which crates the formation level for

the pile cap since the excavation will be dewatered to facilitate construction.



4 Hydrology

Following the infilling of St Helens Canal, P1 is currently in an area of reclaimed land

while the construction phase of the Mersey Gateway Project is carried out.

Bowers Brook, a tributary of the River Mersey, and St Helens Canal are in close

proximity to the structure, with the brook running parallel with, and north of St Helens

Canal. The brook in this area is culverted with an open overflow channel above with a

number of interception trenches to allow flood water within the culvert to rise into the

channel / recede from the channel. Additional detail is contained within the Ramboll

reports: Bowers Brook Research Report (Ref: B4027E/AW/RE/R/027, Rev -, dated

February 2014); and Bowers Brook Interpretative Report (Ref: B4027E/AW/RE/R/028,

Rev -, dated September 2014).



5 Assessment of Contamination

5.1 Field Observations

The following observations indicating visual or olfactory evidence of contamination

were noted on the borehole log for BHXX1 (Glacial Sands):

• Mild organic odour (not known if from a natural or anthropogenic origin) was

noted in BHXX1 between 3.5 and 3.8m bgl within the gravelly clay alluvial

deposits (potentially the base of the Made Ground).

• An organic odour (potentially relating to a natural source) was noted between

8.5 and 9.5m bgl within the sandy alluvial deposits containing traces of organic

matter.

• A strong sulphurous odour was noted from 17.6 to 18.7m bgl within the glacial

sand deposits.

There was no visual or olfactory evidence of contamination noted on the other

borehole logs within the secant wall structure (BHXX2 (sandstone), BHXX4 and

BHXX5).

5.2 Assessment of Soil Chemical Data

Soil samples relating to BHXX1-BHXX5 were submitted to Scientific Analysis

Laboratories Ltd (SAL) for analysis between October 2014 and April 2015. A selection

of soil samples were taken from different depths. The depths ranged from 3.8m to

40.0m and were mostly from the superficial deposits below the Made Ground with a

few deeper samples representing the glacial deposits taken from BHXX2. As the

source of the Made Ground was clean, natural quarried stone (used in the reclamation

of the canal to construct a temporary haul road) this zone was not targeted.

The soil samples were tested for a number of analytical suites, namely phenols, total

petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH), volatile

organic compounds (VOC), semi-volatile organic compounds (SVOC), metals and

inorganics. The analytical suites were selected based on findings during previous

phases of ground investigations works (refer to the PRA for more details).

The soils data are presented in Table 2. The lab reports are presented in Appendix C

for reference.



5.2.1 VOC in Soils

Chloroform was detected in soils samples from all five borehole locations. The soil

samples which exhibited the chloroform were from towards the base of the alluvial

deposits and top of the glacial deposits (sample depths from 8.0 to 13.5m). The

highest concentration of chloroform was 0.43 mg/kg in BHXX2 at 10.1m depth. Similar

concentrations were also reported in BHXX3 (0.35mg/kg at 10.5m), BHXX4

(0.16mg/kg at 10.3m) and BHXX5 (0.22 mg/kg at 10.0m).

At two borehole locations, BHXX1 and BHXX3, carbon tetrachloride was reported at

the base of the alluvial deposits at concentrations of 0.068 and 0.058 mg/kg,

marginally above the method detection limit (0.05mg/kg).

Tetrachloroethene was reported in two soil samples from one borehole location,

BHXX4, at concentrations of 0.073 and 0.077 mg/kg (sample depths of 10.0m and

5.2m, respectively.

These VOCs (chloroform, carbon tetrachloride and tetrachloroethene) were detected

from the alluvial deposits (and on occasions the top of the underlying glacial clay

deposits). The analytical data indicates that these VOC were not identified within soil

samples taken from the deeper glacial deposits.

Carbon disulphide was tested in soils samples from just two of the boreholes, BHXX4

and BHXX5. Concentrations ranged from 0.5 to 260mg/kg in BHXX4 with highest

concentration reported in the soil sample at 10.0m at the base of the alluvial deposits.

Concentrations ranged from 8.4 to 56mg/kg in BHXX5 and, similarly, the highest

concentration was from a soil sample at 10.0m. Carbon disulphide concentrations

decreased significantly in samples below 10m in the underlying glacial clay deposits.

5.2.2 Metals in Soils

Some elevated metal concentrations were detected at the base of the Made Ground in

BHXX2 at 3.8m, namely arsenic (380mg/kg), copper (380mg/kg), lead (390mg/kg) and

zinc (2,300 mg/kg).

Low to non-detect concentrations of metals were detected in deeper samples

collected from the underlying Alluvium, Glacial deposits and Sandstone bedrock.



5.2.3 Other analytical suites

Though some aliphatic and aromatic TPH fractions (carbon banding C16-C21 and

C21-C35) and PAH compounds were reported at low concentrations near to the limit

of detection in the shallowest soil sample (BHXX2 at 3.8m), TPH and PAH were not

detected in any of the other soil samples analysed by the laboratory. Phenols and

SVOC were not detected in any of the soil samples above the limit of detection.

5.3 Assessment of Groundwater Chemical Data

The groundwater sampling rounds undertaken at BHXX1-BHXX5 are as follows:

• BHXX1 and BHXX2: Three rounds on the 7th, 17th and 24th November 2014.

• BHXX3: Four rounds on 18th and 24th November 2014, 1st December 2014

and 29th April 2015.

• BHXX4 and BHXX5: Two rounds of groundwater monitoring on 29th April 2015

and 5th May 2015.

Note that additional chemical data are available for BHXX3 as this monitoring well was

part of the wider groundwater monitoring network until it was decommissioned in

August 2015. However, data from only four monitoring rounds from coincident

sampling events have been assessed in order to make direct comparisons with limited

dataset available which represents conditions inside the secant wall.

Since some monitoring wells have been destroyed it is not possible to understand how

concentrations vary spatially at any one given time at all five monitoring locations.

With this current dataset an assessment of the impact of the secant wall on

contaminant concentrations in groundwater is somewhat limited.

All groundwater samples were submitted to Envirolab for chemical analysis and tested

for the same analytical suites as for the soil samples. The results for the monitoring

rounds listed above are presented in Table 3 and summarised below. The lab reports

are presented in Appendix D for reference.

5.3.1 VOC in Groundwater

The highest concentrations of VOC in groundwater were reported on the 29th April

2015 in BHXX3, BHXX4 and BHXX5 associated with the alluvial deposits. Similar

carbon tetrachloride concentrations of 53,525µg/l and 54,234µg/l were reported in



BHXX4 and BHXX3, respectively (i.e. both inside and outside the bounds of the

secant wall). This is a significant increase in carbon tetrachloride concentration at

BHXX3 for the sample from 29th April 2015, as sampling and testing from the initial

three monitoring rounds in November and December 2014 gave concentrations of

between 509 and 1,316µg/l. A groundwater sample from BHXX5 reported

concentrations of 107 and 413µg/l indicating a wide variation in concentrations within

the Alluvial Sands. It is possible that the spikes in VOC concentrations (see Section

5.5 for more details) are related to the presence of globules of DNAPL within the

groundwater samples. These concentrations significantly exceed the Water

Framework Directive (WFD) Environmental Quality Standard (EQS) for fresh water

(2010) which is set at 12µg/l for carbon tetrachloride.

The next highest VOC concentrations were reported for chloroform with 14,723µg/l

reported in the sample from BHXX4 on 29th April 2014. On the same date 670µg/l and

2,330µg/l of chloroform were reported in samples from BHXX3 and BHXX5. These

concentrations exceed the EQS of 2.5µg/l.

Elevated carbon disulphide concentrations were reported in samples from BHXX4 at

1,547 and 1,486µg/l on 29th April 2015 and 5th May 2015. These concentrations are at

least an order of magnitude greater that those recorded in samples from BHXX3 and

BHXX5.

Relatively low concentrations of tetrachloroethene (between 2 and 59µg/l) were

reported in samples from BHXX3, BHXX4 and BHXX5.

Dichloromethane was reported in samples from BHXX4 at 54 and 58µg/l. Lower

concentrations were reported in samples from BHXX5 (21µg/l) on 29th April 2015 but

were not detected on the following monitoring round. This VOC was not detected in

any of the groundwater samples from BHXX3. Dichloromethane is a biodegradation

product of chloroform, so its presence could suggest that conditions are favourable for

natural attenuation processes within the alluvial deposits. Between 29th April and 5th

May 2015 there was a reduction in chlorinated solvent concentrations in BHXX4 and

BHXX5 within the bounds of the secant wall, however, it is not possible to discern

trends from two monitoring rounds over a very short period of time.

A number of other VOCs, namely chloromethane, cis-1,2-dichloroethene,

trichloroethene, 1,1-dichloropropene and 1,1,2,2-tetrachloroethene, were reported



only in groundwater samples from BHXX4 although concentrations just marginally

exceeded detection limits.

A large variation in COPC concentrations was reported in BHXX4 and BHXX5,

although these boreholes are located 9m apart and occupy a small volume of

groundwater which is confined by the secant wall. The predominant groundwater flow

direction in the area of P1 is assumed to be towards the south-east and so BHXX4

and BHXX5 were likely to be positioned cross gradient with respect to direction of any

plume of COPC in groundwater. It is possible that BHXX4 was located within the

COPC plume whereas BHXX5 was located on the edge of it. Since groundwater flow

is prevented by the secant wall structure, the mixing of COPC in groundwater within

the secant wall is assumed to be minimal and will occur mainly by diffusion processes,

which are very slow.

The concentrations of VOCs in groundwater from the underlying glacial sands

(BHXX1) were generally less than those reported in the alluvial deposits. However,

concentrations of two VOCs, chloroform (270 to 838µg/l) and carbon tetrachloride (71

to 215µg/l), were above their respective EQS of 2.5µg/l and 12µg/l, respectively.

VOCs were not detected in groundwater samples from the sandstone strata (BHXX2).

In summary, the data provides evidence that a migration pathway for COPC, such as

chloroform and carbon tetrachloride in groundwater, exists from the alluvium to the

underlying glacial sand deposits. Given the consistent approximate 2.5m thickness of

glacial clay measured at the P1 location, it is considered that this migration pathway

may be present at a different location up-hydraulic gradient of this area.

5.3.2 Metals in Groundwater

Within the alluvial deposits, concentrations of dissolved arsenic in groundwater

samples were particularly high, at between 7,480 and 9,780µg/l, in BHXX3. Inside the

secant wall arsenic was reported at 1,370 and 2,400µg/l at BHXX4, and between 14

and 73µg/l in BHXX5. With the exception of one sample, these results exceed the

EQS of 50µg/l for arsenic.

Elevated arsenic concentrations were also detected within the glacial sands (BHXX1)

ranging from 99 to 421µg/l, These data may also indicate that a migration pathway

from the alluvial deposits across the glacial clays to the glacial sands may be present.



Very low levels of arsenic (3µg/l) were reported in groundwater from the sandstone

bedrock (BHXX2). This is likely to be indicative of natural conditions given that

regional groundwater quality databases indicated mean concentrations for arsenic of

11.5µg/l and a maximum of 355µg/l recorded within the Triassic Sandstone aquifer of

the Liverpool area (BGS 2005).

A few other metals were detected within groundwater samples but they only

marginally exceeded the EQS and were not considered to be of significance:

• Alluvial Sands:

o Maximum mercury concentration of 0.4µg/l in BHXX5 compared to EQS of

0.05µg/l; and

o Maximum zinc concentrations at 21µg/l in BHXX4 compared to EQS of

8µg/l.

• Sandstone Bedrock:

o Maximum chromium concentration of 14µg/l in BHXX2 compared to EQS

of 3.4µg/) Regional sandstone quality data indicates mean concentrations

of 1.7µg/l and a maximum of 42.8µg/l (BGS 2005);

5.3.3 SVOC in Groundwater

Di-n-octyl phthalate in groundwater samples from BHXX4 and BHXX5 at 47 and

56µg/l respectively on 29th April 2015 exceeded the EQS (20µg/l). This compound was

detected once in BHXX1 on 7th November 2015 at 17µg/l and has not been detected

in the other groundwater samples. No other SVOCs were detected in the groundwater

samples.

5.3.4 Other analytical suites

PAH compounds were not detected in any of the groundwater samples, nor were

phenols. Relatively low concentrations of heavy-end aliphatic and aromatic TPH

fractions (predominantly carbon banding C21-C35) in groundwater have been

reported in samples from BHXX3 and BHXX4 (Alluvial Sands).



5.4 Summary of Compounds of Potential Concern

The compounds of potential concern (COPC) are found in groundwater associated

with the alluvial deposits (and to a significantly lesser degree the glacial sands) and

relate to the following VOC, SVOC and metals:

• Chloroform;

• Carbon tetrachloride;

• Tetrachloroethene;

• Carbon Disulphide;

• Dichloromethane;

• Di-n-octyl phthalate; and

• Arsenic

5.5 Evidence of Dense Non-Aqueous Phase Liquids (DNAPL)

Chlorinated solvents are typically used as neat liquids which have a density greater

than that of water. As a result chlorinated solvents are commonly known as dense

non-aqueous phase liquids, or ‘DNAPL’. When they are released into the ground,

they do not form floating layers but rather have the ability to migrate to depths below

the groundwater table. They can form pools of discrete DNAPL within geologic media

before slowly dissolving into flowing groundwater to produce dissolved-phase plumes

of COPC. More typically, DNAPL form ganglia or strings and are difficult to detect

using traditional techniques. AECOM are not aware of any discrete DNAPL layers

being detected, e.g. by using an oil-water interface probe during groundwater

monitoring events completed in the vicinity of P1 to date.

Although it is rarely possible to observe DNAPL (as free phase droplets in samples), it

is possible to infer the potential presence of DNAPL at the site using other lines of

evidence. The reported chlorinated solvent concentrations in groundwater have been

compared against their respective solubility data using guidance in Section 7.7 of the

EA’s R&D Publication 1331. The chlorinated VOC concentrations data for four

groundwater samples (two samples each from BHXX4 and BHXX5 on 29th April 2015

and 5th May 2015) are presented in Table 4.

1 An illustrated handbook of DNAPL transport and fate in the subsurface, R&D Publication 133, Environment Agency, June 2003



The concentration reported for carbon tetrachloride in groundwater from BHXX4 on

29th April 2015 (53,525µg/l) was 6.3% of its aqueous solubility. The percentages are

greater when taking into consideration the additive effect of all of the chlorinated

solvents that were reported in groundwater (6.6% for this particular sample).

In general, groundwater concentrations of chlorinated solvents that exceed 1% of their

aqueous solubility are indicative of the potential presence of a residual DNAPL in the

vicinity of the sample location, which could therefore be present within the water-

bearing alluvial deposits at P1.



6 Conceptual Site Model

6.1 Introduction

The CSM is based on current ground conditions based on the latest information

available at the time of writing.

6.2 Source

The Made Ground local to P1 is imported road stone as part of the land reclamation

works that were undertaken to facilitate the construction phases of the Mersey

Gateway Bridge. COPC were not identified in the soil samples taken from the

underlying natural deposits. However, elevated concentrations of COPC were

reported in the groundwater samples, in particular those from the alluvial deposits

(BHXX4 and BHXX5). The review of the data available suggests that the source (or

potentially multiple sources) of the COPC is located up hydraulic gradient (i.e. to the

northwest) of P1. Refer to Sections 6.3 and 7.3 of the PRA document for more details

on potential source areas.

Details about the source (including its origin, age, size, volume of COPC released to

the ground and timescales) remain unknown. As such the spatial extent (both laterally

and vertically) and flow path of the plume of COPC migrating in groundwater primarily

through the alluvial deposits in the area surrounding P1 also remains unknown.

6.3 Pathway

Based on the limited data available, the main pathway for the COPC is via

groundwater within the alluvial deposits. The construction of the secant wall (a series

of overlapping piles) has trapped chlorinated solvents within the P1 structure by virtue

of severing the pathway of contaminant movement via groundwater flow within the

alluvial deposits.

Concentrations of COPC within the glacial sand deposits (BHXX2) were generally

lower than those reported in the alluvial deposits. However, concentrations of

chloroform and carbon tetrachloride were in excess of the EQS in the glacial sands

indicating that a migration pathway for COPC in groundwater through the alluvial

deposits to the underlying glacial clay and sand deposits is already present (again

probably in areas up-hydraulic gradient of the P1 structure). These COPC, however,

were not detected in groundwater samples collected from the sandstone bedrock



strata (principal aquifer) indicating that the thick layers of glacial clays (of relatively low

permeability) currently affording protection to the underlying sandstone bedrock by

means of attenuation. It is likely that the main component of groundwater flow will be

laterally within the alluvial deposits. However, the secant wall barrier is locally

preventing migration via this flow path.

6.4 Receptors

In terms of controlled waters receptors, groundwater within the secant wall is laterally

cut off from surrounding surface water features. As outlined in the report section

above, a viable pollutant linkage to the underlying bedrock (principal aquifer) is

considered unlikely.

In this specific instance the COPC (i.e. chlorinated solvents) within the P1 structure

are not considered to pose potential risks to surface waters or human health

receptors.

However, the purpose of the secant wall was to prevent chlorinated solvents from

migrating into the P1 foundations and thence to the underlying strata penetrated by

the proposed piling. It is therefore apparent that a plume of groundwater impacted with

chlorinated solvents was already in situ when the secant wall was constructed.



7 Conclusions

The conclusions drawn from this CSM concerning the P1 structure are as follows:

• A number of COPC are trapped within the water bearing alluvial deposits

within the area bounded by the secant wall (a series of overlapping piles) at

P1. The COPC that have been identified in groundwater samples taken from

monitoring wells BHXX4 and BHXX5 are:

o Chloroform;

o Carbon tetrachloride;

o Tetrachloroethene;

o Carbon Disulphide;

o Dichloromethane;

o Di-n-octyl phthalate; and

o Arsenic

• The data provides evidence that a migration pathway for COPC, such as

chloroform and carbon tetrachloride in groundwater, exists from the Made

Ground through the alluvium to the underlying glacial till deposits. This

pathway is likely to be located in areas up-hydraulic gradient of the P1

structure.

• A large variation in concentrations was reported in BHXX4 and BHXX5,

although these boreholes are located 9m apart and occupy a small volume of

groundwater which is confined by the secant wall. The predominant

groundwater flow direction in the area of P1 is assumed to be towards the

south-east and so BHXX4 and BHXX5 were likely to be positioned cross

gradient with respect to direction of any plume of COPC in groundwater. It is

possible that BHXX4 was located within the COPC plume whereas BHXX5

was located on the edge of it. Since groundwater flow is prevented by the

secant wall structure, the mixing of COPC in groundwater within the secant

wall is assumed to be minimal and will occur mainly by diffusion processes,

which are very slow.

• The concentration reported for carbon tetrachloride in groundwater sampled

from BHXX4 on 29th April 2015 (53,525µg/l) was 6.3% of its aqueous

solubility. The percentages are greater when taking into consideration the

additive effect of all of the chlorinated solvents that were reported in

groundwater (6.6% for this particular sample). These concentrations are



greater than the 1% threshold and could be indicative of the possible

presence of a DNAPL within the alluvial deposits in the vicinity of this well.

• The groundwater level within the secant wall rose by between 1.0 and 1.3m in

BHXX4 and BHXX5, but this was not observed in BHXX3 outside the secant

wall. It is considered possible that rainfall-recharge could artificially raise

groundwater elevations within P1, as this additional water is trapped by the

secant wall barrier. The downward infiltration of groundwater into underlying

strata will be attenuated by the low permeability layer of glacial clay deposits

at the base of the alluvium. In addition, construction activities at the site could

also have a local impact on groundwater levels within the P1 structure.

• The exact origin of the COPC within the P1 structure remains unknown. The

groundwater flow direction within the alluvial deposits is not well understood

and therefore the presence or otherwise of a flow path for COPC migrating in

groundwater remains unclear. The findings indicate that layers of glacial clays

(of relatively low permeability) below the alluvial deposits will inhibit the

downward migration of COPC and afford protection to the underlying

sandstone bedrock. It is likely that the main component of groundwater flow

will be laterally within the alluvial deposits. However, the secant wall barrier is

locally preventing groundwater movement via this flow path.

• The COPC within the P1 structure are not currently considered to pose a

potential risks to surface waters or human health receptors.

It is apparent that a plume of groundwater impacted with chlorinated solvents was

already in situ when the secant wall was constructed. The purpose of the secant wall

was to prevent chlorinated solvents from migrating into the P1 foundations and thence

to underlying strata via the piling. However, this is not to say that the construction

works associated with the secant wall have not exacerbated the impact of existing

contaminants in the P1 area.

Assessment of the potential that construction works have had an impact on

concentrations of contaminants in groundwater in the area of the P1 structure would

be undertaken outwith the CSM and PRA documents and in accordance with the

mechanisms set out in the WQMP.

This CSM will be used to inform the remedial options appraisal and remedial strategy

which will follow in a separate document. The remedial strategy will provide details of



the measures required to mitigate and minimise the potential risks to controlled waters

from the P1 piling installation works.

REPORT NOTES

Notes - Soil chemical analysis All results are reported as dry weight (<40°C). For samples with Matrix Codes 1 - 6 natural stones >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 supercedes any "A" subscripts. All analysis is performed on the sample as received for soil samples 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 a 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. 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.
