Site Event/Activity record ECH6329 - Nantwich Waterlogged Deposits, Cheshire: Phase 2 Interim Report (Report No. 4)

A fourth, interim report on the results of Phase 2 of the Nantwich waterlogged Deposits Project, whose purpose is to develop an effective methodology to monitor the condition of the waterlogged deposits in Nantwich over a three-year period and to update the strategy to manage these remains effectively. In September 2013 a variation was agreed by English Heritage, extending the duration of the project for a further two years, so that in total five years of monitoring data will be gathered. The details relating to Phase 1 of the Nantwich Waterlogged Deposits project are recorded in a separate report1 completed in November 2009, followed by three annual interim reports234 which summarised the works undertaken as part of Phase 2 between 2011 and 2013. These previous reports should be read in conjunction with the present report. This report presents a summary of the fieldwork undertaken as part of the project during 2014, which comprised the following key elements:  Collecting groundwater samples from each of the fifteen separate dipwell locations for geochemical laboratory analysis;  Completing quarterly monitoring at all of the eighteen dipwells for depth to groundwater, water quality parameters and ground gas concentrations.
