Stormwater is the result of standing water from the accumulation of heavy rain and snow precipitation.
Stormwater runoff carries many substances that pollute our waters.
Some substances, including pesticides, fertilizers, oil, industrial waste, and soap, are harmful in any quantity.
In sufficient quantities, others, including sediment runoff from construction sites, bare soil, agricultural land, pet waste, grass clippings and leaves can harm creeks, rivers and lakes .
Runoff from various human activities such as lawn watering, car washing, and malfunctioning septic tank can also pollute land and surface waters. Some of this stormwater runoff eventually ends up in our rivers, sounds and the ocean with devastating results.
