Liu, J. AND Mike Borst. Three Permeable Pavements Performances for Priority Metal Pollutants and Metals associated with Deicing Chemicals from Edison Parking Lot, NJ - abstract. Presented at EWRI Confernce, West Palm Beach, FL, May 22 - 26, 2016.
Impact/Purpose:
Presentation will give the results of metal concentrations in infiltrate from permeable pavement.
Description:
The U.S. Environmental Protection Agency 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 (PICP), pervious concrete (PC), and porous asphalt (PA)]. Samples of each permeable pavement infiltrate, surface runoff from traditional asphalt (CC), and rainwater (RW) were analyzed in duplicate for 22 metals (total and dissolved). Samples were collected at roughly 1-month intervals for 1.5 years. Although the infiltrate metals concentrations varied by surfaces, the measured concentrations in more than 85% of the permeable pavement infiltrates met the groundwater effluent limitations (GEL) for Lead, Copper, Zinc, Chromium, Cadmium, Nickel and Beryllium. More than 50% of the concentrations in infiltrate samples met the Arsenic and Antimony GELs with no measurable difference were found between concentrations in permeable pavements infiltrates and CC. Concentrations in all permeable pavements infiltrates were less than the Manganese GEL. More than 85% of measured concentrations in PA and PC infiltrate water met the GELs for Aluminum and Iron, whereas only 49% and 22% met these values of PICP infiltrates. Total metal concentrations in PICP infiltrates were statistically larger than CC and RW for Aluminum, Iron, Manganese, Sodium, Magnesium and Calcium. The concentrations in the PA infiltrates were statistically larger than runoff concentrations for Aluminum, Sodium and Calcium. The infiltrate Sodium concentration from PC was statistically larger than runoff concentration.
