Dave Allen from the British Geological Survey (BGS) is working in the Hampshire Avon DTC sub-catchments to develop conceptual models of the hydrogeology of the Hampshire Avon DTC sub-catchments.  This has been funded primarily by their national capability funding, with a small amount from the Hampshire Avon DTC project.

Dave visited the catchment a couple of times in 2012.  On his first visit he explored the target sub-catchments to clarify spring sources, borehole locations and other unknown 'issues' to help in the preparation of selecting the best areas to sample to date recharge waters.  On his second visit, Dave and a team from BGS sampled various spring sources and boreholes for CFCs and SF6s.  This information has been fed into the development of conceptual models of the hydrogeology of the Hampshire Avon DTC sub-catchments.
