Table 1 Concentration-based TN removal efficiencies (%) for four low impact development (LID) technologies (adapted from Collins et al. [42])
LID Technologya | Median |
|---|---|
Green roofs (n = 9) | 7.4% |
Permeable pavement (n = 5) | −2.4% |
Bioretention - Conventional (n = 17) | 25% |
Bioretention - Modified (n = 5) | 54.2% |
