16 UCMR Schedule Plan Unregulated Contaminant Monitoring Rule 2 (UCMR 2) Safewater Home UCM Home UCMR 2 Home Fact Sheet Regulation Contaminant List Reporting Methods Laboratories Meetings & Materials Fact Sheet - Proposed Rule Unregulated Contaminant Monitoring Regulation (UCMR 2) monitoring is proposed to occur during and includes 26 unregulated contaminants and nine associated analytical methods to be used in this monitoring cycle. The UCMR program was developed in coordination with the Contaminant Candidate List (CCL). The CCL is a list of contaminants that are not regulated by national primary drinking water regulation, are known or anticipated to occur at public water systems, and may warrant regulation under the Safe Drinking Water Act. The data collected through the UCMR program is being stored in the National Contaminant Occurrence Database (NCOD) to support analysis and review of contaminant occurrence, to guide the CCL selection process, and to support the Administrator's determination of whether to regulate a contaminant in the interest of protecting public health. Background About this regulation How did EPA select these contaminants? What are the major differences between UCMR 1 and 2? What are the environmental and public health benefits? What is the EPA Laboratory Approval Program for UCMR 2? Background The Safe Drinking Water Act (SDWA), as amended in 1996, requires EPA to establish criteria for a program to monitor unregulated contaminants and to identify no more than 30 contaminants to be monitored every five years. EPA identified and published unregulated contaminants for the previous UCMR cycle (i.e., UCMR 1), and a revised approach for monitoring, in the Federal Register dated September 17, UCMR 1 established a tiered monitoring approach, and required all large public water systems (PWSs) and a representative sample of small PWSs (serving 10,000 or fewer people) to monitor for unregulated contaminants from (The original unregulated contaminant monitoring program ( ) utilized State primacy and required PWSs serving greater than 500 people to monitor.)
