Contaminants from Four New Pervious and Impervious Pavements in a Parking-lot
A previous account (Thompson and James, 1994) described the design, construction and instrumentation of four different pavements - asphalt (AS), concrete brick (CP), and three-inch and four-inch thick concrete paver stones with infiltration cells (E3 and E4) - in both a typical parking-lot and in a laboratory. Sampling of runoff from both sets of four pavements was subsequently carried out, and the analytical results used to estimate the flux of 23 contaminants including heat (Thompson, 1995). This chapter reports the interim conclusions obtained from the parking-lot pavements for the first year after installation.
