| Despite their low wastewater discharges when compared to traditional industries, dental offices are often the focus of mercury investigations due to high concentrations associated with amalgam usage. Through the implementation of many Best Management Practices (BMPs) to address mercury, silver, lead and other wastestreams, many dentists have significantly reduced their environmental discharges. The references in this section are intended to provide additional guidance on these BMPs as well as provide some background to the nature of the environmental problems and cite case studies of successful practices. |
