Common pollutants of concern and sources in stormwater runoff. Adapted from USGS, 2014.
Link to this table.
| Contaminant | Contaminant source1 |
|---|---|
| Nitrogen | Naturally occurring from vegetation decomposition. Anthropogenic sources include fertilizers, farm-animal waste, faulty septic systems |
| Chloride | Salts applied to roads and parking lots during the winter. Natural sources include mineral dissolution |
| Copper | Industrial and domestic waste, mining, mineral leaching, automobile parts and fluids |
| Zinc | Industrial waste; automobile parts and fluids |
| Manganese | Found naturally in sediment and rocks. Anthropogenic sources include mining waste, industrial waste, automobile parts and fluids |
| Nickel | Naturally occurring. Anthropogenic sources include stainless steel and alloy products, mining, refining, automobile parts and fluids |
| Cadmium | Small amounts are naturally occurring. Anthropogenic sources include industrial discharge, mining waste, automobile parts and fluids |
| Chromium | Old mining operations; fossil-fuel combustion; mineral leaching; automobile parts and fluids |
| Pesticides | Residential use of lawn care products; commercial landscaping; animal wastes; municipal right-of-ways; agriculture; feedlots |
| Cyanide | Road salt; fertilizer production |
| PAHs2 | Auto emissions; elicit discharges; asphalt pavement (driveways, roadways and parking lots) with coal tar sealants3 |
| VOCs2 | Crude oil; insecticides; varnishes; paints; gasoline products; degreasers; municipal maintenance activities |
| Oil and grease | Gasoline products; plastics; dyes; rubbers; polishes; solvents; crude oil; insecticides; inks; varnishes; paints; disinfectants; paint removers; degreasers; automobile fluids |
| Microbes (including fecal coliform, E. coli, and pathogens) | Domestic sewage; animal waste; plant or soil material |
1The list of sources is for stormwater runoff only
2PAHs=polyaromatic hydrocarbons; VOCs=volatile organic compounds
