Groundwater chemistry data for the fourth River Basin Management Plan (Vandområdeplan 4)

Groundwater chemistry datasets for the fourth River Basin Management Plan 2027-2032 (Vandområdeplan 4, VP4), to be used primarily in the qualitative risk, status, and trend assessments. Some of the data could also support tasks under the quantitative status assessments. These datasets were prepared as part of the project “Etablering af kemiske grunddata til Vand-områdeplan IV”, funded by The Danish Agency for Green Transition and Aquatic Environment (Styrelsen for Grøn Arealomlægning og Vandmiljø, SGAV, 2025).
