 Assessment of Stormwater Best Management Practices
Level 3 - Synthetic Runoff Testing
An assessment method that doses the stormwater BMPs with a prescribed amount of synthetic stormwater. Measurements such as flow rate and mass of pollutant retained by the stormwater BMP are made. Synthetic runoff testing can be used to assess the performance of a stormwater BMP with regard to runoff volume reduction (e.g., through infiltration) and pollutant retention efficiency. Below are some examples of synthetic runoff testing of a proprietary device:
