| Pollutant Category | Constituent | Treatment Capabilities
(Low = < 30%; Medium = 30-65%; High = 65 -100%) |
|---|---|---|
| Metals1 | Cr, Cu, Zn | High2 |
| Ni, Pb | ||
| Nutrients | Total Nitrogen, TKN | Medium/High |
| Bacteria | Fecal Coliform, E. coli | High |
| Organics | High |
1 Results are for total metals only
2 Treatment capabilities are based mainly on information from sources that referenced only metals as a category and did not provide individual efficiency for specific metals
