Dental waste program | Technical assist ance for dentists | Useful links for dentists | Update your practice's contact information 

## The dental waste program Dental practices that discharg e mercury into the King County sewage system must be in co mpliance with the county limits for mercury. To demonstrate compliance a dental office can install an approved amalgam separator unit or sample its wastewater and apply for a permi t to discharge. Our program conducts compliance inspections at dental offices on an ongoing basis.

Has the installation of Amalgam Separator Units in King County made a difference?
