A Consistent BMP Performance Evaluation Process

When compared to other water pollution sectors, addressing stormwater pollution remains a relatively young discipline. Our collective knowledge of stormwater BMP performance is comprised of a patchwork of studies that relies upon many different methods and protocols in arriving at the reported results.  While we have undoubtedly learned a lot about many different types of BMPs, many unknowns remain and comparing different types of BMPs side by side can be particularly difficult as a result of differences in monitoring methodology.  There are numerous variables that can impact actual BMP performance as well as our ability to accurately measure said performance.
