Stormwater

oil-runoff-into-storm-drainPolluted stormwater runoff causes more than half of the pollution in our waterways, according to the U.S. Environmental Protection Agency. 

Sometimes the solution is a relatively easy fix, especially in residential or small business situations.  However, when dealing with commercial, industrial and construction, the problems are often more complicated.  Hopefully this website, along with the Neponset Stormwater Partnership will help to address the issues related to preventing stormwater pollution.

Stormwater pollution begins when rain water or snow melt flows over land or hard surfaces and does not seep into the ground, instead carrying pollutants such as bacteria, nutrients, metals, and chemicals into local waterways, affecting the cleanliness and health of the water that we rely on for drinking and recreation.

Stormwater runoff generally does not go to a sewer treatment plant to be cleaned. In most cases, polluted runoff gets discharged directly to the nearest river, stream, pond or wetland, adversely affecting plants, fish, animals, and people.

Problems stemming from stormwater pollution include:

  • Sediment can cloud the water and make it difficult or impossible for aquatic plants to grow. Sediment also can destroy aquatic habitats.
  • Excess nutrients can cause algae blooms. When algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Fish and other aquatic organisms can’t exist in water with low dissolved oxygen levels.
  • Bacteria and other pathogens can wash into swimming areas and create health hazards, often making beach closures necessary.
  • Debris—plastic bags, six-pack rings, bottles, and cigarette butts—washed into waterbodies can choke, suffocate, or disable aquatic life like ducks, fish, turtles, and birds.
  • Household hazardous wastes like insecticides, pesticides, paint,
    solvents, used motor oil, and other auto fluids can poison aquatic life. Land animals and people can become sick or die from eating diseased fish and shellfish or ingesting polluted water.
  • Polluted stormwater often affects drinking water sources. This, in turn, can affect human health and increase drinking water treatment costs.
