The Environmental Protection Agency is conducting a test on three different types of porous pavement to devise ways to control runoff from parking lots and streets.
"The EPA's first test site is its Edison, N.J., facility, where the agency has replaced a 3,995-square-meter section of parking lot with three different types of permeable pavement-interlocking concrete pavers, porous concrete and porous asphalt-and planted several rain gardens (pdf) with varying vegetation for the study. (Note: Interlocking concrete pavers are often called porous pavers, although the pavers themselves are not porous.) Researchers will over time evaluate the effectiveness of each pavement type and the rain gardens in removing pollutants from stormwater, and how they help water filter back into the ground, according to the agency."
