What Can Pavement Sealers & Vendors Do?

What Can Pavement Sealers & Vendors Do?

Coal-tar sealcoats are sprayed or brushed on asphalt parking lots, driveways, and roads every several years to improve their appearance, protect against weather and wear and extend their life.  Studies have shown that as much as 50%-75% of PAH contamination found in the sediment throughout the Great Lakes region comes directly from coal-tar sealants.

Many suppliers and retailers have voluntarily dropped the product from their inventory, and contractors are committing to using asphalt sealcoats. Please commit to phasing out the use of this dangerous product in your company.

The Minnesota Pollution Control Agency and U.S. Geological Survey have useful information and resources on the topic:

  1. Coal-Tar-Based Pavement Sealcoat, Polycyclic Aromatic Hydrocarbons (PAHs), and Environmental Health
  2. Find companies selling or applying safer sealcoat
  3. Make the pledge to reduce the use of coal tar seal-coats!
