UCMR 6 Pre-Proposal Webinar – April 2024
The EPA hosted two identical pre-proposal webinars on Wednesday, April 17 and Thursday, April 18, 2024, to discuss potential approaches for developing UCMR 6, including: the status of drinking water analytical methods and contaminants being considered; possible sampling design; laboratory approval; other potential aspects of the monitoring approach; and included time for public questions and statements.

UCMR 5 accessing data and communicating results webinars – February 2023
The EPA hosted two identical webinars on February 22 and 23, 2023 to provide public water systems (PWSs), states, and other interested stakeholders with information on how to access UCMR 5 data and resources to assist with understanding and communicating monitoring results. The presentation reviewed the reporting requirements for PWSs and data review functionality in the EPA’s web-based Safe Drinking Water Accession and Review System (SDWARS) for large PWS (i.e., those serving more than 10,000 people), small PWS (i.e., those serving 10,000 or fewer people), and state users. The presentation also discussed the plan for sharing specific preliminary PFAS results from small PWSs with states, reviewed how the public can access UCMR 5 data, and highlighted communication resources for the UCMR 5 contaminants from the EPA and other stakeholders.
UCMR 5 implementation webinars – October 2022
The EPA hosted two virtual meetings (via webinar) on October 26, 2022, and repeated the meetings on October 27, to provide public water systems (PWSs) with a comprehensive overview of the UCMR 5 program and the actions they must take to prepare for monitoring. The meetings addressed monitoring schedules and locations, the Safe Drinking Water Accession and Review System (SDWARS), sampling information, and reporting requirements.
- October 2022 Meeting Material for Small PWSs (those serving 10,000 or fewer people):
- October 2022 Meeting Material for Large PWSs (those serving more than 10,000 people):
- The EPA developed a video to assist small PWSs with how to prepare for and schedule UCMR 5 sampling, collect samples for PFAS and lithium analysis while minimizing cross-contamination, and package and ship the UCMR 5 sampling kit to a contracted laboratory for analysis.
UCMR 5 final rule public webinars – March 2022
The EPA hosted two identical virtual meetings (via webinar) on March 16 and 17, 2022, to provide public water systems (PWSs), states, laboratories, and other stakeholders with a comprehensive overview of the UCMR 5 program. The meetings addressed: 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.

UCMR 5 proposal public webinars – April 2021
The EPA hosted two identical webinars on April 6 and 7, 2021, to discuss the proposed UCMR 5. The meeting scope included the proposed monitoring requirements, analyte selection, analytical methods, laboratory approval process, and ground water representative monitoring plans (GWRMPs).
Approach to UCMR 5 - July 2019
The EPA hosted a public meeting and webinar in July 2019 in Cincinnati, Ohio to discuss potential approaches to developing the proposal for UCMR 5 and allow for early stakeholder engagement.

Methods in development – June 2018
The EPA hosted a public meeting and webinar in June 2018 designed to spark innovation on analytical testing procedures for unregulated contaminants in drinking water.
