Great Lakes Coal Tar Sealcoat PAH Reduction Project

This project supports reduction or phase-out of the use of coal tar-based sealcoats for asphalt pavement surfaces. Such actions will reduce loading of polycyclic aromatic hydrocarbons (PAHs) to surface waters and sediments in Great Lakes states and provinces, and reduce hazards to children and vulnerable adults playing, living or working near coal tar-sealed surfaces like drives, parking lots, and playgrounds.

Freshwater Future, a not-for-profit organization in Michigan, is now leading community-based reduction activities across Great Lakes states and provinces. Please visit the Freshwater Future web page for information on how you can get involved. Contact Cheryl Kallio of Freshwater Future at or 231-571-5001 to get started.
