Good water quality is important for our health, environment and economy. Preventing pollution is the first step. The number one cause of water pollution in Puget Sound today is from polluted rain runoff that has picked up oil and gas, fertilizers, livestock and pet waste and carried it into our waterways. You can help prevent and filter stormwater at home and on the farm.
