UCMR 5 (Unregulated Contaminant Monitoring Rule 5) was published by the EPA on December 27, 2021. UCMR 5 requires sample collection for 30 chemical contaminants - 29 PFAS chemicals and lithium - between 2023 and 2025. This new data will lead to a better understanding of our drinking water and how to prioritize improvements.
While sampling for UCMR 5 isn't set to begin until 2023 (and carrying through 2025), we're already working with clients to help them develop a plan and budget for the UCMR 5 requirements. Scroll down to contact us with your questions or to schedule a discussion for your organization.
All public water systems (PWS) serving more than 10,000 people are required to perform sampling on a quarterly or semi-annual basis for one year.
To continue our legacy as a preferred UCMR testing laboratory, along with our previous UCMR 4 accreditation we are also now a UCMR 5 accredited testing lab.
Microbac employs a consultative approach to deliver a wide range of solutions to meet your water testing priorities:
During UCMR 4, Microbac successfully analyzed over 6,500 samples from public water systems through our comprehensive UCMR 4 test kit. Your dedicated, hands-on Microbac point of contact for UCMR 5 guides you through the entire scope of required testing with complete transparency at every step from shipping to reporting results.
Unlike other companies, Microbac's UCMR 5 program is one flat price and we do not charge to report results to the EPA's central data exchange (CDX).
"I would like to take a moment to let you know that through the questions and quote phase, my Microbac point of contact was very informative and a big part of my selection process. I am looking forward to the smooth road ahead!"

"Thank you for meeting with me and training me on UCMR 4 sampling. The UCMR 4 sample kit and sampling instructions put me at ease for these sampling events. The Microbac Team put a great deal of thought into simplifying the sampling and analysis process from beginning to end. As a Water Operator, I really appreciated this."

All samples must be tested for 29 PFAS contaminants through EPA 537.1 and EPA 533. Testing for lithium through EPA 200.7 is also required.
