Monitoring programmes

In different programmes, GEUS monitors the groundwater quality, as well as the agricultural nutrient contribution to the aquatic environment. We are also part of the Danish Pesticide Leaching Assessment Programme.

Groundwater monitoring

GEUS is the Danish specialist data centre for groundwater and wells, and participates in the national groundwater-monitoring programme (GRUMO), the main purpose of which is to provide data on the quality and quantity of the groundwater. The monitoring includes wells and the collection and test of water samples for e.g. nitrates and pesticides.

Land monitoring programme

The focus of the land monitoring programme (LOOP) is on the agricultural contribution of nutrients to the aquatic environment. LOOP is part of the National Programme for monitoring the aquatic environment and nature (NOVANA). The land monitoring includes collection of data on agricultural practices and monitoring of water from the root zone and drainage water. GEUS’ role is to deliver professional advice based on 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.
