Liu, J. AND Mike Borst. Performances of Metal Concentrations from Three Permeable Pavement Infiltrates. WATER RESEARCH. Elsevier Science Ltd, New York, NY, 136:41-53, (2018). https://doi.org/10.1016/j.watres.2018.02.050
Permeable surfaces allow for stormwater to infiltrate into the subsurface and reduce the volume of surface runoff. This paper characterizes the metal concentrations in rainwater, surface runoff, and the infiltrate from three different permeable pavements. The metal concentration from the Edison parking lot was compared to existing standards (GEL and MCL) to determine the potential impact of permeable pavement infiltrates on groundwater and, when the system included an underdrain, surface waters. This work also evaluated the use of permeable pavements as a stormwater management strategy and showed the advantages and disadvantages of each. Cities, communities, planners, engineers, and regulators considering the use of a permeable parking lot for stormwater management could apply these results.
The U.S. Environmental Protection Agency designed and constructed a 4000-m2 parking lot in Edison, New Jersey in 2009. The parking lot is surfaced with three permeable pavements: permeable interlocking concrete pavers, pervious concrete, and porous asphalt. Water sampling was conducted over a period of 6 years from infiltrates of the three permeable pavements, surface runoff from traditional asphalt, and rainwater, and were analyzed for 22 metals (total and dissolved). The ability of permeable pavement to reduce metal concentrations infiltrating into groundwater was assessed.
