Stormwater is water from precipitation
that flows across the ground when it rains or when snow and
ice melt. Some of the water seeps into the ground. Water
that is not absorbed and thus flows across the surface to storm
drains, streams, and rivers is called runoff.
Runoff can pose a threat to the quality
of water in our streams and rivers because of the pollution
it carries. Every drop of precipitation that strikes the
soil loosens particles that wash away and end up as sediment
in streams. Sediment and other debris clog fish gills, damage
fish habitat, and block the light needed for plants to survive.
In addition to sediment, runoff carries other
pollutants it encounters on the ground and pavement. Common
pollutants include oil, gasoline, and antifreeze dripped by
cars and trucks; chemicals used on lawns and gardens; litter
from improperly disposed trash; and livestock and pet waste.
- Landscape with grass, shrubs, trees, and other plants
to hold the soil together, lessening the chance of erosion.
- Retain and maintain natural wooded areas, including
the forest floor, to filter runoff.
- Use mulch and other soil amendments to increase absorption
of runoff.
- Pick up pet waste and dispose of it with your household
garbage.
- Have your soil tested every three years and fertilize
accordingly.
- Recycle used motor oil, and keep your car in good
repair.
- And always remember that storm drains are not trash cans.
They lead directly to streams, depositing runoff and all of
the pollutants carried with it. Please don’t dump in
storm drains!
