Practical ways to lessen pollution and to use landscaping and management to manage storm runoff.
You don’t need a heavy rainstorm or a Hurricane Fran or Floyd to send pollutants rushing toward North Carolina’s streams, wetlands, lakes, estuaries, and the Atlantic Ocean. A garden hose or sprinkler alone can supply enough water.
The next time you are home during a rain shower, head outdoors with your boots and umbrella and watch where the rainwater goes. Does water soak into the ground quickly, or does it collect in puddles and flow off lawns and driveways? Do you see a stormwater superhighway? Is your rooftop connected to a gutter system that is adjacent to a sidewalk or driveway that drains into a concrete-lined ditch? Soil type affects how water infiltrates (soaks into the ground). As you might expect, water quickly infiltrates sandy soil, such as in the coastal plain or sandhills, but has a hard time seeping into fine-grained clay soils, such as those found in the piedmont or the rocky soils of the mountains.
