1. Brief description of problem: Groundwater Dependent Terrestrial Ecosystems (GWDTEs) monitoring to assess if they have been significantly damaged as a result of groundwater pollution. Evidence for groundwater body status related to GWDTE protected areas. At present, there is a lack of information on the impact of groundwater quality on the GWDTE. Drilling required at WRAYSBURY & HYTHE END GRAVEL PITS, FRAY'S FARM MEADOWS, SAWBRIDGEWORTH MARSH, RYE MEADS, MOOR HALL MEADOWS, TEWINBURY, DENHAM LOCK WOOD, SARRATT BOTTOM.
2. Brief description of services required: It is proposed to drill some new boreholes in areas where there is a paucity of groundwater quality information and we think there may have been potential source areas and to undertake up to 2 rounds of surface and groundwater monitoring of some existing boreholes. These boreholes would need to be up to 8 metres deep to intersect the aquifer and 100 mm diameter. We would proposed up to 3-4 new boreholes per location (see Appendix A for locations) 1) Wraybury & Hythe End Gravel Pits 2) Moor Hall Meadows 3) Tewinbury 4) Sarratt Bottom 5) Denham Lock Wood & Fray’s Farm Meadows 6) Ryemeads
