Groundwater Mapping

Groundwater is one of Denmark's most vital natural resources, supplying the majority of our drinking water. The Danish groundwater mapping initiative ensures sustainable management and protection of this resource, safeguarding it for future generations.

What is Groundwater Mapping?

Groundwater mapping involves detailed studies to understand the distribution, quantity, and quality of groundwater. This mapping is critical for identifying areas suitable for drinking water extraction and areas vulnerable to contamination. In Denmark, this process is managed by the Danish Environmental Protection Agency (Miljøstyrelsen).

Why is Groundwater Mapping Important?

  • Drinking Water Security: Over 99% of Denmark's drinking water comes from groundwater. Accurate mapping ensures safe extraction and monitoring.
  • Environmental Protection: Groundwater mapping supports efforts to reduce pollution and maintain ecosystems reliant on groundwater.
  • Land Use Planning: Data from groundwater mapping informs agricultural, industrial, and urban planning to prevent contamination and over-extraction.
