The Problem with Stormwater Runoff
| Runoff : The water from rain or melted snow that does not infiltrate
the soil but flows over the land surface; precipitation drainage. |
Everything that goes into a storm drain, flows out into
the groundwater, streams, lakes, or river.
In karst areas, sinkholes are nature's storm drains, and the dissolved caves
beneath are like nature's piping system. As groundwater moves through the earth,
wide open spaces such as caves can carry thousands of gallons of water at a time.
This groundwater reemerges on the surface as springs or through wells.
Each time trash, motor oil, anti-freeze, litter, pet waste, fertilizer, yard
and garden debris, household chemicals, and road sand and salt are dumped on
the ground or washed into storm drains, drinking water, groundwater, and aquatic
life are endangered. With every rain or snow these pollutants can be carried
into the groundwater/surface water system.
What You Can Do at Home
- Never dump anything into a storm drain or sinkhole.
- Recycle
motor oil at a local gas station.
- Use fertilizers wisely. Have soil tested
to determine proper amounts.
- Keep pesticide use to a minimum. Use least toxic
alternatives.
- The size and shape of the vegetated zone needed will
depend on the slope of Maintain vegetation on steep slopes to
keep soil in
place.
- Compost yard and garden debris.
- Do not overfill car radiators
and fix leaks.
Pollution from Rooftops
- Roof runoff contains water pollutants such as bird droppings, chemicals
from roofing materials, and heavy metals leached from gutter. In
an EPA study, roof runoff was one of the most toxic samples collected.
- Move
down spouts from roof gutters so water discharges onto grassy
areas away from foundations and septic systems. This will allow
runoff to filter into
the soil, where harmful pollutants are broken down by soil organisms.
