Predictors selected in multivariate regressions for pathogen concentrations in three Milwaukee, Wisconsin area streams, 2007–2008.
| Pathogens | Predictor variables | Standardized coefficient |
|---|---|---|
| Human viruses | Maximum flow | 7.60 |
| Cos(T)a | 4.26 | |
| Precipitation intensity | 0.36 | |
| 3-day antecedent rainfall | 0.006 | |
| 10-day antecedent rainfall | − 0.002 | |
| Sum of human and bovine viruses | Event or low flow | 3.75 |
| Cos(T) | 2.00 |
