Impact/Purpose:
This research describes the results of long-term monitoring of the infiltrate from three permeable surfaces for nutrients. Nutrients are an environmental concern in many surface and groundwaters. Understanding the differences in the infiltrate concentrations will allow communities to select a permeable surface appropriate to the location. Long trends provide insight in the applicability of short term studies available in the literature. The results will be of interest to stormwater control measure designers, regulators, and the public
Description:
There is limited information about long- term effects of permeable pavement parking lots on concentrations of nutrients in infiltrates. A 0.40-ha parking lot that contained three types of permeable pavement including permeable interlocking concrete pavement, porous asphalt and pervious concrete was constructed in 2010 at a U.S. EPA facility in Edison, New Jersey. This study was conducted from October 2010 to August 2017 and samples were collected and analyzed for different nutrients. Water quality samples were collected from the rainfall, parking- lot runoff, and infiltrates from three impervious pavements. For all analytes, there were no differences between permeable interlocking concrete paver and pervious concrete median concentrations. The results showed, that none of the pavements reduced total nitrogen (TN) concentration. The porous asphalt infiltrate had the smallest median phosphate concentration. Data showed distribution of species is changed and supported nitrification process. Nitrogen species showed slowly increasing trends in rainwater, pervious concrete and permeable interlocking concrete paver infiltrates while phosphate showed a slightly increasing trend in rainwater and porous asphalt infiltrates. It is recommended that the communities select a more suitable permeable surface based on the nutrients and stormwater targets .
