MassDEP released drinking water guidelines today for five PFAS chemicals and sent the following information to Public Water Suppliers and other parties.
 

From the Waste Site Cleanup perspective, the background information on the development of the guideline will also serve as background information for Waste Site Cleanup’s soon-to-be-proposed MCP Method 1 GW-1 Standard for PFAS. 

MassDEP expects to keep us up-to-date throughout the summer on the status of the proposed MCP revisions and MassDEP’s approach to PFAS.
