Industrial and Commercial

Industrial and Commercial wastes are among the many common stormwater pollutants that can degrade water quality. Stormwater runoff has been found to contain high concentrations of metals, organics, oil and grease. When these wastes wash into our waters they can kill aquatic organisms. Metals such as chromium, cadmium, lead, and zinc have the potential to contaminate drinking water supplies as well as bioaccumulate in aquatic life. Organics such as engine degreasers, cleaners, and other solvents can also degrade water quality.

NEW: Rainy Season Preparation Letter: 

Review your Best Management Practices (BMPs) in preparation for the rainy season, October 1-April 30. See the rainy season preparation letter for helpful information.

Use Best Management Practices (BMPs)! 

BMPs are techniques or controls used to prevent or reduce the discharge of pollutants, such as fertilizers, pesticides, and organic wastes, into the stormwater conveyance system also known as the storm drain system. The helpful documents below and the Guidance Handbook To Reduce Water Pollution are references to help reduce pollutants to our stormwater system and local waterways.

Helpful Information and Documents:



  • Avoid over watering after fertilizer application. 
  • Use less-toxic alternatives.
