Pervious concrete as a paving material has generated tremendous interest due to its ability to allow water to flow through itself to recharge groundwater and minimize storm water runoff.

According to a recent study in Texas by the U.S. Geological Survey National Water-Quality Assessment (NAWQA) Program and the City of Austin, the black emulsion sealcoat applied to asphalt pavement has extremely elevated concentrations of polycyclic aromatic hydrocarbons (PAHs) and can significantly affect the quality of downstream water resources.
