Pollutant removal percentages for filtration BMPs.
Link to this table
| Practice | TSS Low-Med-High | TP Low-Med-High | TN4 | Metals3 (average of Zn and Cu) | Bacteria3 | Hydrocarbons3 |
|---|---|---|---|---|---|---|
| Media Filter1 | 75-85-90 | 30-50-55 | 35 | 80 | 35 | 80 |
| Vegetative Filter2 | see here | see here | 35 | 80 | 35 | 80 |
1 For example, sand, mixed sand/peat and other geologic media
2 Grass filter/swale
3 Not enough information given in databases to differentiate type of filter so both combined for this entry
