STORM WATER

Storm water is the runoff of water originated during precipitation of rain or snow. It is the water that flows over impervious surfaces that prevent the water from soaking into the ground, such as roads, sidewalks, and driveways.

Storm Water Pollution

Storm water runoff picks up debris, chemicals, oils, and other pollutants which flow into sewer systems or directly into lakes, streams, rivers, wetlands or coastal water. These contaminants end up in water bodies used for swimming, fishing, and drinking. The contaminated storm water runoff causes adverse effects to plants, animals and people alike.

Residential Contaminants

The storm water runoff from residential property winds up in storm drains that carry the untreated water directly into local water bodies. Many household products contain chemicals, such as insecticides, pesticides, paint, solvent, motor oil, and detergents. Excessive use of fertilizers also pollute streams, in addition to leaves, lawn and yard clippings. Even pet waste can be a problem, as it can be a major source of bacteria and excess nutrients in local waters. Flushing pet waste is the best solution.Water Way with Drain

Commercial Contaminants

Improperly maintained erosion control causes excessive sediment and debris in storm water runoff. The construction vehicles can leak fuel, oil and other fluids that can be carried via storm water into local water bodies. It is important to divert storm water away from construction sites.

Agriculture Issues

Overgrazed pastures contribute to excessive sediment in local water bodies and the use of fertilizers and pesticides kill aquatic animals and lead to destructive algae blooms. Livestock contaminate waterways with bacteria, making the water unsafe for human contact.
