Parking Lot and Storage

file

Pollutants resulting from water running off parking lots and storage facilities are among the many common stormwater pollutants that can degrade water quality. Pollution generated from vehicles parked and stored create a variety of wastes. Stormwater runoff from this waste 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.

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 oil, antifreeze, and solvents, into the stormwater conveyance system also known as the storm drain system.

Tip:

  • Clean oily deposits and dry sweep-up trash and debris regularly.
