Is Coal Tar Waste Toxic?

Yes, coal tar contains high concentrations of PAHs (polycyclic aromatic hyrdocarbons). PAHs make up more than 50 percent of the raw coal tar. The EPA has designated 16 PAHs as priority pollutants and seven of those as probable human carcinogens. Nearly all seven of these PAHs are in raw coal tar. While in sediment, coal tar is not a public health concern. Once it is dredged, coal tar could pose a health risk if the dredged soils are not properly disposed of in an authorized landfill designed to ensure the waste cannot migrate into the environment.
