Non-Point Source Pollution

Runoff diagram

Non-point source pollution is caused by storm water (rain or melting snow) which picks up contaminants as it travels and flows over land through the watershed.

As storm water travels over a variety of surfaces (yards, roof tops, driveways, parking lots & roadways) it picks up and carries anything in its path including litter, yard waste, oil, fertilizer, animal waste, brake fluid, and more. These pollutants drain, untreated, into local waterways. By taking simple steps at home, you can have a positive impact.
