Stormwater that does not soak into the ground becomes surface runoff.
Runoff becomes polluted as it runs along roads, parking lots, roofs, lawns and farms.
Runoff contains pollutants such as automotive fluids, fertilizers and pesticides, bacteria, sediments, litter, and pet waste.
Surface runoff flows into a storm sewer that eventually flows into waterways (rivers, streams, lakes, oceans).
Runoff is typically not treated before it enters the waterways.
Landscape architects are now developing new options to reduce runoff including porous pavement, biodetention ponds, flow through planters, French drains, green roofs, use of native plants, reduction of lawn areas, rain gardens and bioswales.
Plants and soil filter water and improve water quality.
Water quality is the physical, chemical and biological characteristics of water.
The water you drink is affected by stormwater. Rochesterian’s can become an H2O Hero – learn more here.
