Madisonville, January, 2017 - EPA has published the fourth Unregulated Contaminant Monitoring Rule (UCMR 4) in the Federal Register on December 20, 2016. McCoy & McCoy Laboratories, Inc. has submitted the application to begin the process to become an approved laboratory for UCMR 4. MMLI has been a leader in the drinking water monitoring program since the 1996 Safe Drinking Water Act was enacted.
UCMR 4 requires monitoring for 30 chemical contaminants between 2018 and 2020 using analytical methods developed by EPA and consensus organizations. This monitoring provides a basis for future regulatory actions to protect public health.
