What the dataset contains
Contaminated land in Placepoint
Properties registered with contaminated land, and municipal and private/industrial landfills. Distributed by Miljødirektoratet and run as the Grunnforurensningsdatabasen (contaminated land database). The dataset comes from two main sources: planned mapping of localities with known or suspected contamination, and reports from building and excavation cases, orders to investigate, or the owner's own initiative.
For a developer, the dataset is a required check at the zoning stage: plots with registered contamination trigger a requirement for an action plan under the Pollution Control Act and chapter 2 of the Pollution Regulations, and can require extensive groundwork before construction. For valuers and brokers, it is information that belongs in the sales prospectus and the valuation. Part of Placepoint's Pollution map layer. Related: Wastewater facilities, NADAG – ground investigations, Mineral resources.

About the datasetHow often is contaminated land updated?
Real time. The update frequency follows the source and is shown on the dataset in Placepoint.
Where does the data come from?
From Miljødirektoratet. We collect the data, check its quality and link it to the correct property, with the source and date on every field.
How do I see contaminated land for a property?
Look up the address in Fusion and turn on the Pollution map layer. The dataset is there as a separate layer, and the details appear in the property panel when you click on the map.
Can I get the dataset programmatically?
Yes. The same data is available in Placepoint API and in Placepoint AI through MCP, so you can bring it into your own systems and agents.
