US EPA regulates dental mercury discharge

December 15th, 2016 by michael

EPA issued a new rule to control dental mercury releases from  entering municipal treatment plants, the nation’s waters and the fish Americans eat. EPA’s rule requires dental clinics to install amalgam separators and implement “best management practices.”  The Agency expects compliance will reduce mercury discharges by over 10 tons per year. “Mercury from dental clinics is the largest source of mercury in municipal wastewater, the largest consumer use and also the largest reservoir of mercury in use today,” MPP’s director said in a statement. “Amalgam separators are easy to install and maintain.  They are also a practical, affordable and available technology for capturing mercury.” According to EPA, removing mercury at dental offices—where it is concentrated and easy to manage—is both an economical and common sense solution to prevent releases.  EPA estimates that the average annual cost of the rule per dental office is about 800 dollars.
