November 1, 2022, the Division of Drinking Water (DDW) posted a copy of the new PFAS Monitoring Order. This Monitoring Order rescinds DDW’s two previous PFAS Monitoring Orders: (1) Order DW 2021-0001 and (2) Order DW 2020-0003.
This new PFAS monitoring order requires quarterly monitoring with the first sample collected before March 31, 2023. Also enclosed is the template cover letter to public water systems, and the two attachments to the Monitoring Order (Exhibit A is a list of sources that are to be monitored and Exhibit B is a list of detection levels for purposes of reporting results in Consumer Confidence Reports). Monitoring is to be conducted using EPA Method 533.
