Pollution Prevention Information for Residents

Did you know that the soap and oil that goes down the storm drain when you wash your car is harmful to water quality and to the fish and other life in the creeks? And the pesticides you spray on your yard, if sprayed right before a rain can wash off and kill beneficial insects in the creeks? Please click here for a flyer about pollutants typical for a home and yard.
