  18. UCMR 3 Monitoring Frequency • PWSs must monitor during a consecutive 12-month period between 2013 - 2015 • Number of times a PWS samples is directly related to the sample point source • Surface Water and Ground Water under the Direct Influence of Surface Water – must monitor quarterly during their 12-month schedule (sampling events three months apart) • Ground Water – must monitor twice during their 12-month schedule (sampling events five to seven months apart) • EPA established a monitoring schedule for all PWSs • PWSs can change their pre-determined schedule in SDWARS by November 29, 2012, independently, or after that date with EPA permission

  19. UCMR 3 Monitoring Locations • All samples for UCMR 3 contaminants will be collected at the Entry Point to the Distribution System (EP or EPTDS); in addition three methods will also be collected at the Distribution System Maximum Residence Time (DSMRT)

  20. UCMR 3 Monitoring Locations – Field Blanks Due to susceptibility to outside source contamination, UCMR3 requires field blanks to be processed, extracted and analyzed for three of the List 1 Methods and the List 2 Method if there is a contaminant detected in the associated field sample. Field Blanks will be included with the following methods: • List 1 • EPA Method 524.3 • Collected at the EPTDS • EPA Method 537 • Collected at the EPTDS • EPA 200.8 • Collected at the EPTDS & at the DSMRT • List 2 • EPA Method 539 • Collected at the EPTDS

  21. UCMR 3 Monitoring and Reporting • Small PWSs serving 10,000 or fewer people are not responsible for the costs associated with the analysis • EPA coordinates sample analyses with contracted laboratories • Laboratories submit the data directly to the EPA • EPA examines the quality control results and generates reports • EPA collects samples for only List 3 contaminants • PWS reviews and can act upon data in SDWARS 3

  22. UCMR 3 Monitoring and Reporting Large PWSs serving more than 10,000 people are responsible for the costs associated with the analyses • PWS coordinates sample analyses with an approved laboratory, and that lab sends the data to the Safe Drinking Water Accession and Review System (SDWARS 3) • http://cdx.epa.gov/epa_home.asp • PWS reviews and can act upon data in SDWARS 3

  23. UCMR 3 Reporting Elements

  24. UCMR 3 Reporting Elements • All of the disinfectants that have been added to the water being sampled must be reported by systems for each sampling point with possible choices being: • CLGA – Gaseous chlorine • CLOF – Offsite Generated Hypochlorite (stored as liquid) • CLON – Onsite Generated Hypochlorite (no storage) • GAGC – Chloramine (formed from gaseous chlorine) • CAOF – Chloramine (formed from offsite hypochlorite) • CAON – Chloramine (formed from onsite hypochlorite) • CLDO – Chlorine Dioxide • OZON – Ozone • ULVL – Ultraviolet Light • OTHD – All other Types of Disinfectant • NODU – No Disinfectant Used

  25. UCMR 3 Key Dates – November 29, 2012 • Systems must submit contact information to SDWARS. • Subsequent changes must be submitted within 30 days of the change occurring • Systems can change their monitoring schedule, and review and edit if necessary, inventory information for sampling locations. • After November 29th, systems must request a change (with an explanation) and obtain EPA approval of the change

  26. UCMR 3 Data Reporting • Samples must be analyzed by EPA-approved laboratories. • EPA-approved laboratories will be listed on the UCMR website at: http://water.epa.gov/lawsregs/rulesregs/sdwa/ucmr/ucmr3/laboratories.cfm • Within 120 days of sample collection • Laboratories post data to SDWARS • Within 60 days of lab posting data • PWS reviews and approves the data. If the PWS has not taken action after 60 days, the data are considered approved and ready for state and EPA review

  27. EPA Use of UCMR 3 Data • Updated quarterly by EPA and posted in the National Contaminant Database (NCOD) • www.epa/safewater/databases/ncod/index.html • Data will continue to be added and may be corrected upon further review • Use caution when interpreting the data before the dataset is complete • UCMR 3 is one of the primary sources of occurrence and exposure information the agency uses to develop regulatory decisions for contaminants of concern
