Washington state is now the largest government in the country to ban the cancer-causing industrial waste. The asphalt sealant is used on surfaces such as driveways, parking lots, and even playgrounds. One US Representative is seeking a nationwide ban. "The Washington state legislation and Doggett’s drive for a nationwide ban flowed from studies by the U.S. Geological Survey, which showed that components of the toxic sealants are increasing in many waterways, while levels of most pollutants are declining."
Looks like you haven't made a choice yet.
