UCMR 3
At UL, we take pride in our technical expertise and experience to analyze for emerging contaminants, as well as our in-depth understanding of the proposed Unregulated Contaminant Monitoring Rule 3 (UCMR 3). This knowledge allows us to serve as a resource for our customers as they develop and implement their monitoring schedules. Our customers and regulatory agencies also have the confidence that the data generated by UL will meet the compliance requirements of this rule.
Key facts regarding UCMR 3
Like UCMR 1 & 2, UCMR 3 is designed to collect occurrence data on chemicals identified in the Contaminant Candidate List. These chemicals are not regulated by national primary drinking water regulations, but are known or anticipated to occur at public water systems, and may warrant regulation under the Safe Drinking Water Act. Below are some things to keep in mind as your system prepares to comply with UCMR 3:
Assessment Monitoring — EPA is proposing to require all public water systems (PWSs) serving more than 10,000 people, and a representative sample of 800 PWSs serving 10,000 or fewer people, to conduct Assessment Monitoring for 28 chemicals (List 1) during a 12-month period in January 2013– December 2015.
