Concerned about PAHs in Parking Lot Sealcoats? - Environmental - Ecology and Nature Protection
There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content. In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff. Sitelab can be used to quickly check the concentrations of polycyclic aromatic hydrocarbons and determine if it's made from coal tar or alternative petroleum based black top sealants. Got samples? We'll test them for free! Contact Sitelab Corporation for details.
