Amalgam contains mercury. Mercury is a potent neurotoxin that bioaccumulates in fish and shellfish and ultimately affects human health and the environment.
The United States Environmental Protection Agency (USEPA) has set a national standard that will reduce the discharge of mercury containing dental amalgam from dental practices to sewer plants. The standard includes mandatory use of amalgam separators or similar devices, and Best Management Practices (BMP's) endorsed by the American Dental Association (ADA). Compliance with this rule is phased in over 3 years.
Depending on your specific practice, different requirements and deadlines must be achieved.
