What is it about?
We looked for about 1000 trace organic compounds in groundwater to see if these were related to land use and pollution sources in two areas in southern England. In different parts of the Oxford floodplain we could detect compounds coming from an old landfill, from the sewered area and from agriculture. In a rural area we could detect agricultural pesticides and compounds from a cattle shed or from a sewage works outfall.

Why is it important?
The different types of compounds originating from activities at the surface can be used as tracers to help us to understand how groundwater is moving about at a local scale.
