A score for the overall quality of local surface water (rivers, lakes, streams), ranging from 0 to 10, with higher numbers indicating cleaner waterways.
This score measures the freshwater you actually swim in, fish in, or live next to, not literally tap water. Buyers care about it for recreational water use, property value next to clean water, contamination risk to private wells, and the overall environmental health of the area.
In Finland this is the Finnish Environment Institute's 2022 ecological classification of each water body, on England's classes.
