STORMWATER
Stormwater is the largest source of pollutants, such as road salt,
heavy metals, gasoline, nutrients, and antifreeze, in the drinking
water supply. Because it does not come from a single source, pollution
from surface water runoff is hard to detect and control. It is also
more damaging to fish, wildlife and their habitat as well as drinking
water supplies. Impervious surfaces are nearly 100% hydrologically
active-meaning they generate surface runoff- and usually involve permanent
impacts to the land that result in the land not being able to be returned
to its natural state. Once an impervious surface is constructed, it
will affect the quantity, velocity and quality of stormwater resulting
in impacts to nearby waterbodies.
