New USGS Report: Runoff from coal-tar-based sealant is toxic to aquatic life.  
The U.S. Geological Survey recently published two studies in Environmental Science and Technology and Science of the Total Environment indicating that runoff from pavement with coal-tar-based sealant is toxic to aquatic life, damages DNA, and impairs DNA repair.Coal-tar-based sealants are painted or sprayed on parking lots, driveways, and playgrounds to protect underlying asphalt and improve the appearance. These sealants contain high levels of polycyclic aromatic hydrocarbons (PAHs) that are probable human carcinogens and are toxic to aquatic life.

For more information visit the U.S. Geological Survey page about PAHs and coal-tar-based sealants.

PREP is part of the U.S. Environmental Protection Agency’s National Estuary Program, a joint program between local, state and federal agencies established under the Clean Water Act with the goal of protecting and enhancing nationally significant estuarine resources. PREP is supported in part by an EPA matching grant and is housed within the School of Marine Science and Ocean Engineering at the University of New Hampshire.
