The Pollutant Removal Efficiency Conundrum

Over the last several years, there has been considerable debate regarding the science of measuring the performance of a best management practice (BMP)–as a percent removal efficiency (%RE) measured by influent and effluent event mean concentration (EMC), as an effluent concentration, or as a mass balanced removal efficiency.
