We’ve identified more than 12,500 confirmed or suspected contaminated sites in Washington. Sites range widely in size and complexity — from gas station spills to abandoned mines leaching chemicals into a river, to landfills leaking methane gas, to a smelter plume depositing contaminants over thousands of acres.
Cleanup actions have a powerful impact on human health, communities, and the environment. They help restore habitat for wildlife, and they provide new opportunities for recreation, spur economic development, and put abandoned properties back into use.
