Drinking water interests in Denmark
Areas of special drinking water interest (OSD) are assigned the highest priority for drinking water supply. They are delineated according to criteria including future water demand, groundwater quality, natural protection, and the preservation of existing abstraction infrastructure. The spatial extent of OSD areas may be adjusted as new knowledge becomes available through fee-financed groundwater mapping under the Environmental Objectives Act § 8a. Within these areas and abstraction catchments for public waterworks, action plans are developed under Chapter 3 of the Water Supply Act. Areas of drinking water interest (OD) represent regions with groundwater of suitable quality for drinking water, primarily relevant for smaller utilities and local abstraction.
The data are provided as a vector Dataset and are accessible via OGC web services. Source data are obtained from the Danish Environmental Protection Agency’s groundwater delineations (as of November 2022) and reflect the state of knowledge at publication time.

Lineage describes the origin and history of the dataset – i.e. how the data was obtained, which sources were used, and which treatments or transformations were performed. The purpose is for others to understand where the data comes from and how reliable it is.
1. Brief description of the data sources (e.g. field surveys, existing databases, public registers).
2. Important processing steps that the dataset has undergone (e.g. reprojection, generalization, quality control).
3. Any external contributors or reference to original datasets if GEUS has not collected the data itself.
Example of a good lineage statement:
"The dataset is based on geological mapping carried out by GEUS in the period 2000–2020. Data has been checked for consistency and reprojected to ETRS89 / UTM zone 32N. For external data, the source and publication are documented."
