| Practice | TSS Low-Med-High4 | TP Low-Med-High4 | TN5 | Cu5 | Zn5 |
|---|---|---|---|---|---|
| Media Filter2 | 5-11-16 | 0.06-0.10-0.19 | 1.1 | 0.008 | 0.060 |
| Vegetative Filter3 | 13-20-44 | 0.15-0.24-0.36 | 1.1 | 0.008 | 0.060 |
1 All concentration values in mg/L which equals parts per million
2 For example, sand, mixed sand/peat and other geologic media
3 Grass filter/swale
4 See Appendix N discussion
5 Not enough information given in databases to differentiate type of filter so both combined for this entry
