Each time it rains, water washes over our streets, driveways and yards picking up pollutants along the way and flowing into our storm drains. This runoff may contain pollutants such as motor oil, yard clippings, pet waste, litter, lawn chemicals, anti-freeze, or other materials, which can pollute our water supply as well as clog pipes and culverts which can lead to flooding. Known as “Non-Point Source Pollution”, it is the largest threat to our waterways today. Sometimes, pollutants are dumped directly into storm drains by neighbors who don’t know any better. Sometimes, they are washed off of roofs, driveways, streets and parking lots by rainfall runoff. Contrary to popular opinion, our storm drains are NOT connected to treatment systems. Whatever enters the drain is discharged directly, untreated, into our local waterways!
