Non-Storm Water runoff is any activity or event which results in a release, leak, flow, escape or the placement of any material (liquid or solid) other than rain water into our storm drains, roadside ditches and creeks. It is important to prevent pollutants from entering our storm drain systems in order to protect public health and our local waterways. Storm drain systems include streets, curbs and gutters, storm drains, roadside ditches, and creeks.

The following are examples of the different types of pollutants reported to Sonoma County:

• Soil and sediment
• Paints and solvents
• Garbage or Trash
• Detergents and soapy wash water
• Concrete and asphalt compounds
• Fuel, oil, and grease
• Pool and spa discharges
• Animal waste
• Hazardous chemicals
• Sewage or Septic discharges
