Law, N., R. D. Christianson, L. Fraley-McNeal, G. Hoffman. 2014. Building the Next Generation of Smart BMPs: Media Enhancements for Phosphorus Removal. Watershed Bulletin. Center for Watershed Protection, Ellicott City, MD. The science and practice of stormwater management to improve best management practices to protect and restore water resources is an ongoing field of study. Innovation to develop smart BMPs is an essential component of stormwater management given the high cost of retrofitting urban areas and required pollutant load reductions to meet TMDLs and other local program goals. The focus of this paper is a review of the use of media additives to enhance the phosphorus (P) removal from BMPs and to identify information needs to move this innovation from research to practical application. A review of different types of additives and their pollutant removal capabilities is described along with information needs to move this smart BMP from research into practice.
