The Agricultural Catchment Monitoring
The focus of The Agricultural Catchment Monitoring Program (LOOP) is on the agricultural contribution of nutrients to the aquatic environment. LOOP is part of the National Program for Monitoring the Aquatic Environment and Nature (NOVANA). The monitoring activities include collection of data on national and local agricultural practices, monitoring of water from the root zone, drainage water and shallow groundwater. GEUS’ role as Topic Centre is to deliver scientifically based advice and prepare the reporting of the groundwater quality and quantity in five LOOP catchment areas.

The Pesticide Leaching Assessment Programme
The purpose of the Danish Pesticide Leaching Assessment Programme (VAP) is to investigate whether approved pesticides or their degradation products leach into groundwater in concentrations above the limit value. In addition, other parameters are analysed that may affect pesticide leaching, for example inorganic chemical parameters.
