Introduction
This Technical Note is intended to provide a preliminary ground conditions review which aims to assess the potential for shallow groundwater flow from the Phase 1 development to the land immediately adjacent to the eastern boundary which includes a pond owned by a third party. This Technical Note should be read in conjunction with Waterman’s Technical Note (WIE14468-ES007) titled ‘Existing Pond adjacent to Sites Eastern Boundary’ which concludes that:
‘the upstream catchment for the pond is located within the land parcel to the east of the development site. Additionally the lower ground levels within the development site provide a flow route past the existing pond and are considered to convey any overland flows within the development site past the pond to the watercourse further to the north.’
Phase 1 is shown to be undeveloped farmland with the buildings of Park Fields Farm to the south of the site
from the earliest available map dated 1882 (Ref. 1) and which remain relatively unchanged to present day
confirming the greenfield nature of the site.
Discussion
Two phases of intrusive ground investigation have been completed between 2014 and 2016 and are discussed
in the following section along with publically available information for the site. A more comprehensive review
is presented in the Atkins’ Preliminary Geo-environmental Assessment (Ref.1) and Travis Baker’s Site
Investigation Report (Ref. 2).
Geo-environmental Setting
The British Geological Survey (BGS) Sheet 140, Burton-upon-Trent (Ref. 3) indicates that the site is underlain
by Superficial Deposits comprising Glacial Till and Bedrock Deposits of the Mercia Mudstone Group (MMG).
The Environment Agency groundwater vulnerability map in the Envirocheck Report classifies the underlying
Superficial Deposits of Glacial Till as a Secondary Undifferentiated Aquifer.
The Environment Agency describes a Secondary Undifferentiated Aquifer (Ref. 4) as “….assigned in cases
where it has not been possible to attribute either category A or B to a rock type. In most cases, this means that
the layer in question has previously been designated as both minor and non-aquifer in different locations due
to the variable characteristics of the rock type.
The Environment Agency classify the underlying Mercia Mudstone Group as a Secondary B Aquifer which is
described (Ref. 4) as “....predominantly lower permeability layers which may store and yield limited amounts
of groundwater due to localised features such as fissures, thin permeable horizons and weathering. These are
generally the water-bearing parts of the former non-aquifers.”
Recorded Ground Conditions
Six exploratory holes undertaken during recent ground investigation works are considered to be the most
representative of the area closest to the pond location adjacent to the eastern boundary. Two of these
exploratory holes (TP107 & SW3) were undertaken by Atkins (Ref. 1) and the remaining four (LP3-LP5 & TP2)
2
were undertaken by Travis Baker (Ref. 2).The exploratory hole logs and corresponding location plans are
included in Appendix A and B respectively.
Superficial natural drift deposits (Glacial Till) were encountered all of the exploratory holes underlying the
Topsoil. The Superficial Deposits, where penetrated, was proven to depths of between 0.65m (LP03 – Travis
Baker) and 2m bgl (LP04 – Travis Baker).
The Superficial Deposits were noted to be variable both in terms of their composition and in thickness. The
Superficial Deposits typically comprised bands of sandy gravelly clay, clayey sand and gravel and a sand and
gravel. The cohesive materials typically were observed as soft to stiff in consistency.
Mercia Mudstone was encountered underlying the Superficial Deposits within four of the exploratory holes.
The base of the Mercia Mudstone was not proven beyond 5m bgl (LP5).
Where encountered, the Mercia Mudstone was typically encountered as a firm to stiff and very stiff red, red
brown and occasionally mottled grey. It is noted as becoming friable with depth. Some weaker horizons of
fine grained sandstone were encountered during the ground investigations and Travis Baker suggested that
these horizons were considered to represent weathered strata of the Mercia Mudstone Formation.
During excavation of the trial pits, groundwater was only identified in two exploratory holes, at 2m bgl (SW3)
and encountered in TP02 only as a slow seepage (Ref. 2). Soakaway test SW3 was undertaken wholly within
the Superficial Deposits with the results suggesting negligible infiltration potential.
Conclusions
The disparity of shallow groundwater within the exploratory holes along the eastern boundary suggests that
groundwater is present in discrete pockets and therefore unlikely to be in hydraulic continuity across the site.
Furthermore, the negligible infiltration rate recorded within SW3 confirms the predominantly cohesive nature
of shallow surface soils which is consistent with the geology recorded by the BGS. The negligible infiltration
also suggests that waterbodies in the local vicinity are likely to be in low permeable soils and fed predominantly
by overland surface water flow and precipitation. It is therefore considered unlikely that the base flow
groundwater contribution to the pond is significant to the ponds hydrology.
