Proposed UCMR5

The proposed Unregulated Contaminant Monitoring Rule 5 (UCMR5) was published in today’s (March 11, 2021) Federal Register (Proposed UCMR5 Federal Register_2021-03-11).  Public comments are due by May 10, 2021.   The proposed monitoring includes 29 PFAS and lithium.  EPA is proposing that PFAS would be measured using EPA Methods 533 and 537.1.  EPA anticipates the monitoring would occur during 2023 to 2025.

Monitoring would be one year of quarterly monitoring for surface water and groundwater under the direct influence of surface water systems, and two samples (5 to 7 months apart) in a 12 month period for groundwater systems.

EPA will host two identical virtual meetings (via webinar) on April 6th (9:00 am to 12:30  pm, ET) and April 7th (1:00 to 4:30 pm, ET)  2021, to discuss the proposed UCMR5. The meeting will include information on “proposed monitoring requirements, analyte selection, analytical methods, laboratory approval process, and ground water representative monitoring plans (GWRMPs).”
