“When water runs off yards, streets, and parking lots into storm sewers or directly into waterways, it carries with it sediments that clog streams and reduce oxygen in the water, as well as chemicals that poison aquatic ecosystems and can render water supplies undrinkable.”
What is Runoff Pollution?
Runoff pollution refers to the contaminants picked up by rainwater and melting snow that washes off the many impermeable surfaces found in urban environments. It is a threat to both the quantity and quality of our water supply.
