- The fifth and latest list (UCMR 5)was published on March 11, 2021, and includes 30 new chemical contaminants that must be monitored between 2023 and 2025 using specified analytical methods.
- Safe Drinking Water Act now requires that UCMR include all large PWSs (serving >10,000 people), all PWSs serving between 3,300 and 10,000 people, and a representative sample of PWSs serving fewer than 3,300 people.
- Large systems must pay for their own testing, and US EPA will pay for analytical costs for small systems.
- Labs must receive EPA UCMR approval to conduct analyses on UCMR 5 contaminants.
AEL was certified to provide analytical services for the upcoming sampling period (2023-2025). No matter what size Public Water Drinking System AEL can help you maintain compliance. AEL is a UCMR Approved Lab.
