Stormwater
Sources
Stormwater comes from rain and anything else that the rain carries along with
it when it runs along the ground. This water is usually only filtered for
large objects and ends up entering the rivers, streams and other bodies of
water. In this mainly untreated state it affects not only the home of many
aquatic animals, but your own drinking and bathing water as well.
What is Point-Source and Non-Point Source Pollution?
Stormwater can include water from both point-sources and from non-point
sources. Point-source locations can create such pollutants as chemical runoff,
oil leaks, sewage and bulk trash. Non-point sources cause pollution from car
fluid leaks, fertilizers from farms, pesticides from gardens, paint, if dumped
into the sink or toilet in your home, trash from littering, and
"natural" litter, such as grass clippings, leaves or animal
feces.
What are the Environmental Impacts
Stormwater pollution harms plants, animals and human beings. Impacts on plants and
animals are:
- reduction of light penetration caused by sediment in the water, which
affects photosynthesis, the process that allows plants to use light as their
source of energy
- supply of oxygen becomes reduced when green waste decays in water, taking
vital oxygen away from plants, fish and other aquatic animals
- soil pollution clouds up waterways, causing fish to suffocate by clogging
their gills
- litter clogs waterways and causes toxicity as it breaks down. It affects
the health of birds, fish and other animals and plants that live in the
waterways.
Impacts on humans are:
- bacterial risk, making it dangerous to swim immediately after rain
- ugly pollution destroys the visual amenity of our waterways
- pollutes drinking and bathing water.
What Can You do to Stop Non-Point Source Pollution?
There are many things that people can do to stop this pollution.
- Changing or stopping everyday activities such as littering or dumping unused paint down
the drain can help.
- Make every effort to put trash into the proper receptacles, and recycle whenever possible.
- Clean up after your dog when taking him or her for a walk.
- Stop using chemicals on your lawn, or if necessary, use environmentally friendly products.
