Stormwater Illicit Discharge
WHERE DOES STORMWATER POLLUTION OR (ILLICIT DISCHARGE) COME FROM?
There are many different types and sources of stormwater pollution. There are the four
main categories of land uses that have impacts on our water resources.
Commercial - Involves businesses that are retail oriented or perform services for
customers. Examples include auto service shops, gas stations, restaurants and lawn
care services. Motor oil, antifreeze, oil filters and cleaners can all be potentially harmful
to the environment if not recycled. Oil and grease contain hydrocarbon compounds,
some of which can injure or kill aquatic life even at low concentrations.
Industrial – Land uses that involves, manufacturing, production or transportation,
including construction activities. Waste generated at an industrial site, when exposed to
rain or outdoor watering, can wash into rivers, streams and lakes.
Residential - Residential areas and neighborhoods can significantly impact rivers, lakes
and streams due to polluted stormwater runoff. Improper disposal of yard clippings,
fertilizer, pesticides, and herbicides can lead to the exposure of excessive nutrients can
discharge into receiving waters (lakes, rivers, streams, and creeks). Washing your
vehicle on the driveway or street allows a perfect opportunity for the soapy water and
other cleaning chemicals to make their way down the street into a storm drain and the
nearest stream. The household hazardous wastes in and around your home can affect
your family and pets and can be toxic to fish and wildlife. A simple solution to water
pollution is picking up after your dog. When it rains, your pet's "business" is washed
down into the street and storm drain contaminating our rivers, lakes and streams with
unhealthy levels of bacteria.
