Tools for this tag

A contaminated area is an area contaminated by chemical agents. Examples include chemical dumps, tailings ponds, and former heavy-industry areas that may still be toxic.

Additional usages:

  • When combined with amenity=drinking_water, indicates a contaminated drinking water source that is still used as a drinking water source despite contamination. If the drinking water source is no longer used because of the contamination, it is not drinkable and thus amenity=drinking_water would be incorrect.
  • When used with natural=water or waterway=*, indicates a contaminated water feature.
