What impact does impervious The volume and velocity of stormwater runoff
cover have on water quality? increases as natural vegetation is replaced
with roads, buildings, parking areas and other
impervious surfaces. The increase in
stormwater runoff leads to an increase in
pollutants, such as sediment and phosphorus
that are carried to waterways, which has a
negative effect on water quality.
