    Report Water Pollution


    Every one of us contributes pollution to our streams, lakes, bays and oceans. The wastewater, dirt, and debris of our lives eventually drains downstream. Each of us must minimize our contribution to keep our waterways healthy and enjoyable. Some materials are powerful pollutants like raw sewage, petroleum, or pesticides, but even natural, biodegradable plant materials can add nitrogen to water resources and cause algal blooms and fish kills. Please use the information below to assist you in reporting an incident to the correct agency. Learn More about Reporting Pollution »
