This report documents the efforts to evaluate simple predictive relationships affecting concentrations of indicator organisms in stormwater runoff based on environmental conditions. It describes the breadth of surface water resources affected by bacterial stressors and identifies the needs for continued research on understanding related engineering approaches. Combined in this report are bench- and pilot-scale data to assess first-order equations to better predict the performance of constructed wetland and retention pond best management practices (BMPs).
