Event mean concentrations for total phosphorus. This table was updated October 31, 2019. We retained data from the previous table, but we recommend using the median values from a literature review (3rd column). To see supporting information used to derive this table, link here.

| Land cover/land use | Range (mg/L) | Median from literature review (mg/L)1 | Recommended value (mg/L)1 | Notes |
|---|---|---|---|---|
| Commercial | 0.20 - 0.34 | 0.17 | 0.20 | If applicable to models being used, adjust curve numbers/runoff coefficients when calculating loads |
| Industrial | 0.23 - 0.55 | 0.235 | 0.235 |
|
| Residential | 0.26 - 0.38 | 0.36 | 0.325 | Concentrations vary widely depending on local conditions |
