Relative pollutant reduction from sand filter systems for metals, nitrogen, bacteria, and organics.
Link to this table
| Pollutant | Constituent | Treatment capabilities1 |
|---|---|---|
| Metals2 | Cadmium, Chromium, Copper, Zinc, Iron, Nickel, Lead | Medium/High3 |
| Nitrogen | Total nitrogen | Low/medium |
| Total Kjeldahl nitrogen | Medium | |
| Bacteria | Fecal coliform, e. coli | Medium |
| Organics | High |
1 Low: < 30%; Medium: 30 to 65%; High: >65%
2 Results are for total metals only
International Stormwater Database, (2012)
3 Treatment capabilities for Cd and Cr are based on results of a single study by Kurz, 1998. This study shows low (9.3%) removal rates for Cr.
