&EPA United States Environmental Protection Agency The Third Unregulated Contaminant Monitoring Rule (UCMR 3) Fact Sheet for Screening Survey Monitoring (List 2 Contaminants) Overview of the Rule * Title: Revisions to the Unregulated Contaminant Monitoring Rule for Public Water Systems; 77 FR 26072, May 2,2012. *J* Purpose: To collect occurrence data for contaminants suspected to be present in drinking water but that do not have health-based standards set under the Safe Drinking Water Act (SDWA). Screening Survey monitoring addresses contaminants with analytical methods that rely on sophisticated technology that may not be as widely used in drinking water laboratories. The UCMR program is the primary source of drinking water contaminant occurrence data used by EPA in regulatory determinations. *»* Description: UCMR 3 includes Screening Survey monitoring for seven List 2 hormones using an EPA-approved analytical method. List 2 contaminants are always associated with a Screening Survey sampling design. Public water systems (PWSs) subject to Screening Survey monitoring will sample within a 12-month period during 2013 - 2015. *»* Utilities Affected: Applicability is based on retail population served for community water systems (CWSs) and non-transient non- community water systems (NTNCWSs). Screening Survey monitoring will be conducted by all systems serving more than 100,000 people; 320 randomly selected systems serving 10,001 to 100,000; and 480 randomly selected systems serving 10,000 or fewer. *»* Occurrence Data: The analytical results from UCMR 3 are stored in the National Contaminant Occurrence Database (NCOD). For a summary of the NCOD results, tips for querying NCOD, and health effects information (including reference concentrations) please refer to the UCMR 3 Data Summary document.

EPA 815-B-11-001. January 2012 Office of Water (MS-140) EPA 815-F-16-002 May 2016 ------- Screening Survey Monitoring *J* Time frame: One consecutive 12-month period during January 2013 - December 2015 (monitoring can span more than one calendar year, as long as conducted during a consecutive 12-month period). *»* Frequency: Ground Water. Monitoring will occur twice in a consecutive 12-month period; sample events must occur 5-7 months apart. Surface Water or GUDI: Monitoring will occur in 4 consecutive quarters, with sampling events occurring 3 months apart. *J* Location: Entry point to the distribution system (EPTDS) for all contaminants. *J* Laboratories: Samples must be analyzed by EPA-approved laboratories. Critical Deadlines and Requirements Due Date Requirement Report Contact through Sampling SDWARS1 Coordinator2 Following Rule Publication October 1,2012 Systems must submit contact information to SDWARS. (Any subsequent changes must be submitted within 30 days of the change occurring). Laboratories seeking approval must submit a registration form to participate in the laboratory approval process. Ground water systems that wish to monitor from representative August 1,2012 EPTDSs must submit either state-approved, UCMR 2-approved or propose a new representative sampling plan. October 1,2012 Deadline for systems to change their monitoring schedule (after October 1, systems must provide an explanation for the requested schedule change and obtain EPA approval of the change). X (after October 1) PWSs review/edit if necessary, inventory information for sampling locations. X (after October 1) Following Sample Collection With in 120 days of sample collection Laboratories post data to SDWARS. With in 60 days of lab posting data PWSs review and approve the data. If the PWS has not taken action after 60 days, the data are considered approved and ready for state and EPA review. 1. Safe Drinking Water Accession and Review System 2.

CWSs may include their public notice within their CCRs. Details on these reporting requirements can be found in the document: Revised Public Notification Handbook (EPA816-R-09-013). Under the Consumer Confidence Report (CCR) Rule, as specified in 40 CFR§141.153(d), CWSs must report the monitoring results whenever unregulated contaminants are detected. CCRs are delivered to all billing customers each year by July 1. (The CCR Rule does not apply to non-community water systems). Details on these reporting requirements can be found on the CCR Home Page.
