Amalgam Regulations

The Massachusetts Department of Environmental Protection (MassDEP) issued regulations that require most dental practices and facilities in Massachusetts to install and operate amalgam separator systems, recycle mercury-containing amalgam wastes, and periodically certify their compliance with these requirements. The regulations, which took effect on April 24, 2006, were developed with assistance from a stakeholder workgroup including individual dentists, MDS representatives, sewerage authorities, and environmental groups. These regulations apply to all Massachusetts dental practices and facilities that generate or discharge wastewater from mercury amalgam-related processes.
