The Center for Watershed Protection has created a comprehensive database of pollutant removal performance for present best management practices such as; dry ponds, wet ponds, wetlands, filtering, bioretention, infiltration (pervious pavement), & open channels. This Database is in its third version and can be viewed via the following link:
National Pollutant Performance Database v3
The pollutant removal values for pervious pavement within this document are summarized as follows:
Total Phosphorus (TP) = 65%
Soluble Phosphorus (Sol P) = 85%
Total Nitrogen (TN) = 42%
Nitrogen as Nitrate & Nitrite (NOx) = 0%
Copper (Cu) = 86%
Zinc (Zn) = 66%
Bacteria = N/A
