On February 22, CSWAB participated in the initial meeting of the PFAS Technical Advisory Group hosted by the Wisconsin DNR in Madison. The goal of the group is to examine the what, where, when and how of PFAS investigation and remediation by sharing concerns, identifying current and proposed practices and strategizing on issues requiring solutions.
After the meeting, CSWAB shared information about state lifetime Health Advisory Levels (HALs) which serve as technical guidance to assist regulators with water consumption advisories and groundwater remediation decisions.
CSWAB is familiar with the topic as we have successfully petitioned for more than a dozen HALs — many associated with munitions contamination at the former Badger Army Ammunition Plant.
Following are source documents with highlighted text pertaining to Wisconsin HALs, including our most recent petition for the summed-total concentration of PFAS in groundwater and drinking water.
