Geochemical Data Collection in LOOP6. MapField, 2019-2020. Results from The Innovation Fund Denmark project: MapField – Field-scale mapping for targeted Nregulation and management (8855-00025B)

This report summarizes existing data and results of the field campaigns carried out in 2019 to collect geochemistry data for the MapField project. The geochemistry data includes groundwater chemistry, sediment chemistry, and nitrate reduction rates. We drilled boreholes to collect groundwater and sediment samples. The primary objectives of the geochemistry data collection are to capture transport and evolution of nitrate in the subsurface at the field scale and to quantify the rates of nitrate reduction. This geochemistry data will be input data for an integrated hydro-geochemistry modelling. Here, we describe the methods and results.
