Main chemical pollutants observed in the urban water environment (After Göbel and others 2007)
| Pollutant group | Substances |
| Suspended solids | Suspended solids may consist of clay, silt, airborne particulates, colloidal organic particles, plankton and other microscopic organisms |
| Biodegradable organics | Composed principally of proteins, carbohydrates, and fats, biodegradable organics are measured most commonly in terms of Biological Oxygen Demand |
| Nutrients | Nitrogen and phosphorus |
| Priority pollutants | About 100 organic or inorganic compounds selected on the basis of their known or suspected carcinogenicity, mutagenicity, teratogenicity or high toxicity |
| Poorly biodegradable organics | Alkanes, Aromatics, Chlorinated alkanes, Chlorinated aromatics, Polycyclic Aromatic Hydrocarbons (PAH), Substituted PAHs, Pesticides, Phenolic compounds, Petroleum hydrocarbons, Pesticides, Pharmaceuticals |
| Heavy metals | Copper, Cadmium, Chromium, Lead, Mercury, Nickel, Tin, Zinc |
| Dissolved inorganics | Salts, Oxygen |
