Landscaping

file

Fertilizers, herbicides, pesticides, and organic wastes are among the many common stormwater pollutants that can degrade water quality. Stormwater runoff from landscaping activities has been found to contain high concentrations of organic wastes, fertilizers, pesticides, herbicides, and soil that can leave a property that you work. When these materials wash into local waters they poison fish and contaminate the water. Soil and dirt washed from the grounds can also harm aquatic life by clogging the gills of fish, blocking light transmission, lowering water temperatures, and inhibiting photosynthesis. Organics, such as grass clippings and leaves, can cause algae blooms and bacteria growth which degrades water quality.

What can I do?

Use Best Management Practices (BMPs)!
BMPs are techniques or controls used to prevent or reduce the discharge of pollutants, such as fertilizers and herbicidies, into the stormwater conveyance system also known as the storm drain system.

Tips:

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