18 UCMR 3 Monitoring Frequency PWSs must monitor during a consecutive 12-month period between 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 18

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) 19 List 1: Assessment Monitoring Contaminants Contaminant Type Sampling Location Type EPTDSDSMRT EPA 524.3: Volatile Organic Compoundsx EPA 537: Perfluorinated Compoundsx EPA 522: Synthetic Organic Compoundsx EPA 300.1: Chloratexx EPA 200.8: Metalsxx EPA 218.7: Chromium-6xx List 2: Screening Survey Contaminants Contaminant Type Sampling Location Type EPTDSDSMRT EPA 539: Hormones x

20 UCMR 3 Monitoring Locations – Field Blanks List 1 EPA Method Collected at the EPTDS EPA Method 537 Collected at the EPTDS EPA Collected at the EPTDS & at the DSMRT 20 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 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 21

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) PWS reviews and can act upon data in SDWARS 3 22

23 UCMR 3 Reporting Elements 23 UCMR 3 Reporting Elements Public Water System Identification Code Disinfection TypeSample Analysis Type Public Water System Facility Identification Code Sample Collection DateAnalytical Results - Sign Water Source TypeSample Identification CodeAnalytical Results - Value Sampling Point Identification Code ContaminantLaboratory Identification Code Sampling Point Type Identification Code Analytical Method CodeSample Event Code As a one-time reporting requirement, PWSs must report the U.S. Postal Service Zip Code(s) for all areas being served water by that PWS.

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 24

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 25

26 UCMR 3 Data Reporting Samples must be analyzed by EPA-approved laboratories. EPA-approved laboratories will be listed on the UCMR website at: es.cfm es.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 26

27 EPA Use of UCMR 3 Data Updated quarterly by EPA and posted in the National Contaminant Database (NCOD) 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 27

30 UCMR 3 Methods Assessment Monitoring (List 1 Contaminants) primarily utilize common analytical method technologies used by drinking water laboratories GC/MS 522 Quadrupole GC/MS 300.1Ion-Chromatography 218.7Ion-Chromatography ICP-MS 537LC/MS/MS 30

31 UCMR 3 Methods Screening Survey (List 2 Contaminants) primarily uses common analytical method technologies used by drinking water laboratories. 539 LC-ESI-MS/MS Pre-Screen Testing (List 3 Contaminants) uses newer method technologies not as commonly used by drinking water laboratories. For UCMR 3 these PWSs are ground water systems that: Serve less than 1,000 people Do not disinfect Are located in areas of karst or fractured bedrock 31

32 UCMR 3 Sampling Information Partnering with your selected laboratory is crucial to your success! Complete and Accurate detail on the Chain of Custody and bottle labels is critical for successful data uploads to SDWARS Following the collection schedule Understand the collection and preservation instructions (Method 522 requires a 2 step preservation process) Be certain that both you and your selected laboratory clearly understand the field blank protocols 32

33 UCMR 3 Sampling Information Properly handling Field Blanks is critical to avoid costly and time consuming recollections. Four Methods require field blanks with each sample (in duplicate) (at both the EPTDS and the DSMRT) Collection protocols differ depending on the method Any field sample with a detect requires analysis of the associated field blank Field Samples with a detect greater than >1/3 MRL requires re-collection 33

34 UCMR 3 Sampling Information Both the sample collector and the primary PWS contact (if not the same person) need to know and understand the Field Blank protocols (EPTDS) Pre-preserved vials filled with reagent water shipped with collection containers DO NOT open in the field (EPTDS and DSMRT) Bottle filled with reagent water shipped with collection containers At the collection site, OPEN the Field Blank, recap, and return with the field samples to the laboratory 537 and 539 (EPTDS) Pre-preserved bottles with reagent water as well as a empty bottle shipped with collection containers At the collection site, transfer the preserved reagent water into the corresponding empty container and return with the field samples to the laboratory 34

35 Sampling Instructions Before Sampling Read all instructions thoroughly as there are multiple sampling procedures required. Remove refrigerant packs from shipping container and place in freezer. The packs must be frozen before returning samples to the laboratory. Plan to have samples collected just prior to the normal pick-up time of your overnight carrier. 35

36 Sampling Instructions Sampling Steps 1.If your sampling point has a faucet with an aerator, it must be removed prior to collection of the samples. 2.Flush the cold water sampling line approximately 10 minutes immediately prior to sampling. 3.Do not touch inside the cap or around the edge of the bottle. 4.Slow the water stream before collection. 5.Refer to the method-specific sampling instructions described below. 6.Indicate sampling date, time, site, and name of sampler on both the bottle labels and the enclosed Chain of Custody. 7.Information on the Chain of Custody and labels must match and be complete. 8.Caution: Bottles and vials may contain chemical preservatives. Avoid skin contact! 36

61 Why is UCMR 3 Testing Expensive? EPA made assumptions that laboratories would take steps with all field blanks to ensure that if analysis of any of the blanks becomes necessary, required holding times would not be exceeded. These assumptions include: All field blanks would be analyzed All 537 and 539 blanks would be extracted EPA’s conservative assumption that all 537 and 539 Field Blanks will be extracted Extraction is only part of the process, it only covers a portion of the total cost if a sample does end up requiring analysis such as Costs associated with additional analytical batches Additional staff salaries for analysis, peer review, client notifications, report generation, and reporting to the client and SDWARS 61

62 Why is UCMR 3 Testing Expensive? (cont.) ParameterCAS # Number of Finished Water samples Analyzed Number of Detects > UCMR3 MRL UCMR3 MRL % w/ Detects >MRL Chromium ug/L 76% Cobalt ug/L 6% Molybdenum ug/L 51% Strontium ug/L 96% Vanadium ug/L 57% Field Blanks were NOT mentioned in EPA’s cost assumptions. Based on a high rate of occurrence as illustrated in the table above, expect field blanks for to require analysis. A Field Blank that requires analysis is not different than a field sample and cost the laboratory the same amount to analyze. Assuming a PWS has just 1 EPTDS and 1 DSMRT, this makes four analyses

63 UCMR 3 Costs - Budgeting & Planning There is no doubt that UCMR 3 is an inexpensive regulation. There are, however, a few things that you can do to spread the cost out and minimize the potential for additional costs. Adjust your schedule in SDWARS so collections fall over 2 fiscal years instead of 1 12 consecutive months does not mean those twelve months must be in the same calendar year If you are required to perform Assessment Monitoring (List 1), a SW supply can collect the last two quarters of one year and the first two of the next year If you are required to perform Screening Survey monitoring, you could collect all of your List 1 samples in one year and all of your List 2 samples in the next year Memorize the Field Blank protocols, this will reduce the likelihood of contamination during collection and potentially avoid additional laboratory fees (some may bill all or a percentage for sample and Field Blank analysis if it is invalid due to contamination during collection) 63
