Unified Interior Regions

Wisconsin

Through advanced research and long-term monitoring, three Wisconsin-based USGS centers-the National Wildlife Health Center, the Upper Midwest Environmental Sciences Center, and the Upper Midwest Water Science Center-provide the scientific information needed by managers, decision makers, and the public to protect, enhance, and restore ecosystems, water resources, and wildlife health in the Midwest.

Gray patches show where sealcoat has worn off
January 1, 0000

Sealcoat wear indicated by bare asphalt patches

The abrasive action of car tires and snow plows causes sealcoat to wear off. Here, light-colored patches indicate where the sealcoat has worn off and the underlying asphalt shows through. Applicators generally recommend reapplication every 3 to 5 years. Read more about coal-tar-based sealcoat and PAHs here.

Black sealcoated pavement contrasts with unsealed pavement
January 1, 0000

Black newly applied sealcoat contrasts with unsealed asphalt

Newly applied coal-tar-based sealcoat is dark black, sharply contrasting with the unsealed asphalt parking lot below. Coal-tar-based sealcoat is a potent source of polycyclic aromatic hydrocarbons (PAHs)

Worn sealcoated pavement around storm drain
January 1, 0000

Worn sealcoat around a storm drain.

Coal-tar-based sealcoat, a potent source of polycyclic aromatic hydrocarbons (PAHs), abrades into fine particles with time.  Here, runoff containing abraded particles goes down a storm drain and is delivered to a nearby lake. Read more about coal-tar-based sealcoat and PAHs here.

Worn sealcoat in Milwaukee, WI

Coal-tar-based sealcoat, a potent source of polycyclic aromatic hydrocarbons (PAHs), abrades into fine particles with time.  Here, runoff containing abraded particles goes down a storm drain and is delivered to a nearby lake. Read more about coal-tar-based sealcoat and PAHs here.
