On April 14, 2011, the Environmental and Energy Study Institute (EESI), Water Environment Federation (WEF), andOffice of Rep. Lloyd Doggett (D-TX) held a briefing featuring new studies by the U.S. Geological Survey (USGS) which found coal tar-based pavement sealants as a major source of polycyclic aromatic hydrocarbons (PAHs) in urban lakes across the country. PAHs are a significant environmental topic because several are probable human carcinogens, they are toxic to fish and other aquatic life, and their concentrations have been increasing in urban lakes in recent decades.
This briefing was held in cooperation with the USGS Office of Water Quality and its National Water-Quality Assessment (NAWQA) Program.
