Pollution prevention

Services and information to help reduce pollution in our environment such as chemicals, soapy water, oil, trash, animal waste and dirt, and where to report pollution.

We work with businesses to keep pollution out of the environment with Best Management Practices (BMPs). Pollution includes dirt, animal waste, trash, oil, soapy water, and chemicals.

When it rains, water picks up what it touches, including pollution. Polluted stormwater is the leading threat to Washington’s environment, especially its waters, because pollutants are not removed from stormwater.
