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
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

• 522
Quadrupole GC/MS
• 300.1
Ion-Chromatography
• 218.7
Ion-Chromatography

30
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
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
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
• 524.3 (in duplicate)
• 200.8 (at both the EPTDS and the DSMRT)
• 537
• 539
• 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
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.
• 524.3 (EPTDS)
• Pre-preserved vials filled with reagent water shipped with collection containers
• DO NOT open in the field
• 200.8 (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
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
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.

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 524.3 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

• 200.8 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 200.8 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
62
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)
