The fifth Unregulated Contaminant Monitoring Rule (UCMR 5) was published in the Federal Register on December 27, 2021. Under UCMR5, monitoring for 29 PFAS and lithium will occur between 2023 and 2025. Surface water systems will conduct one year of quarterly monitoring; groundwater systems will collect two samples (5 to 7 months apart) in a 12 month period.
On March 16, 2022 and March 17, 2022, EPA will host (identical) webinars on the UCMR5.
EPA’s description of the webinars:
“….to provide public water systems (PWSs), states, laboratories, and other stakeholders with a comprehensive overview of the UCMR 5 program. The meetings will address: a general introduction to the UCMR program, PWSs subject to UCMR 5 requirements, the analytes to be monitored, monitoring locations and frequency, reporting requirements, ground water representative monitoring plans (GWRMPs), and the laboratory approval program.”
“The number of webinar connections available for the two webinars is limited and will be offered on a first-come, first-served basis. If stakeholder interest exceeds the maximum number of available connections, EPA may schedule additional webinars….”
