The National Pollutant Removal Performance Database, version 2 (Winer, 2000) consisted of 139 individual best management practice (BMP) performance studies published through 2000. An update of the database has since been conducted to include an additional 27 studies published through 2006. The source information for these additional studies is listed in the References section of this document. The updated database was statistically analyzed to derive the median and quartile removal values for each major group of stormwater BMPs (Figures 1-7).
