The Wisconsin Department of Natural Resources (DNR) expects as many as 90 of the state’s 500 sewerage districts will need to develop and implement a Mercury Pollutant Minimization Program (MPMP) to reduce mercury flow to the greatest extent possible in the coming years. How this impacts dentists will depend on whether their sewerage district must comply with MPMP requirements.
