Regulatory Determinations
Every five years, the Administrator shall, after notice of the preliminary determination
and opportunity for public comment, for not fewer than five contaminants included on
the CCL, make determinations on whether to regulate such contaminants
SDWA requires EPA to publish a maximum contaminant level goal (MCLG) and
promulgate an NPDWR for a contaminant if the Administrator determines that:
1. The contaminant may have an adverse effect on the health of persons;
2. The contaminant is known to occur or there is a substantial likelihood that the
contaminant will occur in PWSs with a frequency and at levels of public health
concern; and
3. In the sole judgment of the Administrator, regulation of such contaminant
presents a meaningful opportunity for health risk reduction for persons served
by PWSs

UCMR Monitoring Tiers
UCMR approach relies on using one or more of 3 monitoring tiers:
Assessment Monitoring (primary approach to-date)
Screening Survey
Pre-Screen Testing
Based on:
Availability and complexity of analytical methods
Laboratory capacity
Sampling frequency
Characteristics of PWSs performing the monitoring
Other considerations (e.g., cost/burden)

Frequently Asked Question
How does EPA determine if a PWS monitors under UCMR 5?
The determination of whether a PWS is required to monitor under
this rule is based on the type of system (e.g., community water
system, non-transient non-community water system, etc.), and its
retail population, as indicated by SDWIS/Fed on February 1, 2021, or
subsequent corrections from the State.
vvEPA

Environmental Protection
Agency
Office of Water
Frequently Asked Question
I purchase 100% of my water, am I subject to UCMR 5?
&
Yes. Purchasing 100% of your water that is supplied to customers does not
exclude a PWS from UCMR 5. 40 CFR 141.40(a)(2) specifies UCMR 5 applicability.
PWSs that purchase any of their water supply (i.e., 0-100%) and serve more than
10,000 people are required to monitor. Systems that serve 3,300 to 10,000
people are required to monitor if appropriations are provided to EPA. Systems
that have a retail population of <3,300 are only required to monitor if they are
selected as part of the nationally representative sample and notified by EPA.

Rule
RE: Medium PWS Registration for U.S. EPA's Fifth Unregulated Contaminant Monitoring
Rule
Dear Public Water System:
Our records indicate that your public water system (PWS) is subject to the requirements of the
next Unregulated Contaminants Monitoring Rule (UCMR 5). published on December 27.
2021 (86 FR 73131). UCMR 5 requires certain PWSs to collect drinking water samples for 29
per- and polyfluoroalkvl substances (PFAS) and lithium analysis during a 12-month period
between 2023 and 2025. This notification provides you with information to access the UCMR
5 internet-based reporting system, the Safe Drinking Water Accession and Review System
(SDWARS 5). so that your account will be ready to support your pre-sampling and monitoring
responsibilities.
The Safe Drinking Water Act (SDWA) requires the U.S. Environmental Protection Agency
(EPA) to establish criteria for a program to monitor unregulated contaminants in drinking
water and to identify contaminants to be monitored every five years. The UCMR dataset is one

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - October 2022 Small Public Water Systems Implementation
Small PWS Notifications
As described in the final UCMR 5, EPA's ability to support monitoring at all small PWSs serving 3,300 to
10,000 people depends on additional appropriations in fiscal years 2024 and 2025
EPA's current funding supports:
Monitoring at the representative national sample of 800 PWSs serving <3,300 people (PWSs notified of
confirmed participation)
Monitoring at ~400 randomly selected PWSs serving 3,300 to 10,000 people (PWSs notified of confirmed
participation)
Prioritizing these PWSs allows EPA to ensure a national random sample for small PWSs serving 210,000
people, irrespective of future appropriations
Monitoring at PWSs serving 3,300 to 10,000 people with sampling scheduled in 2023
These PWSs received the second notification either through SDWARS (if already registered), email, or
physical mailing the week of June 20, 2022
The remaining PWSs will be notified approximately 6 months prior to their scheduled sampling year to
confirm their participation (i.e., by July 1, 2023, for 2024 sampling and by July 1, 2024, for 2025 sampling)
pM United States

mI Agency
Frequently Asked Question
Do the small PWSs have to pay for the monitoring if EPA does not
receive the necessary appropriations?
No. If EPA does not receive appropriations to support the full scope of UCMR
small system monitoring, EPA will reduce the scope of that monitoring for the
PWSs serving 3,300 to 10,000 people.

PWSs will be required to collect samples based on the traditional UCMR sampling
frequency and timeframe
UCMR 5 samples will be collected at non-emergency entry points to the distribution
system (EP or EPTDS) for all contaminants (finished water)
Water Source
Timeframe
Frequency
Surface water, ground water under the direct
influence of surface water, or mixed sources systems
Year-Round
Systems must monitor 4 times during a consecutive
12-month monitoring period.
Sample events must occur 3 months apart.
Ground water systems
Systems must monitor 2 times during a consecutive
Year Round 12 month monitoring period.
Sample events must occur 5 7 months apart.

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - October 2022 Small Public Water Systems Implementation
Frequently Asked Question
I receive water from another water system via a consecutive
connection. Where should I take my entry point to the distribution
system (EPTDS) sample?
EPA advises samplers to collect from the closest location to the EPTDS that can be
readily, safely, and consistently accessed. The PWSs should contact the UCMR Message
Center (UCMR5@glec.com) with additional questions/concerns.

NCOD and Data Summary Document
After UCMR 5 monitoring starts, EPA will update the NCOD and publish a "Data Summary"
approximately quarterly at the link below
The Data Summary will summarize the NCOD results at a national level (e.g., the number of
PWSs with results above the MRL), provide data field definitions, and tabulate health-based
information from EPA risk assessments for the UCMR 5 contaminants alongside MRLs to help
inform interpretation of results
Health-based reference values (e.g., EPA lifetime health advisory values) are reported as
concentrations in water, if available, or reference doses
MRLs are the lowest concentrations that laboratories can report for a UCMR 5 contaminant
EPA will continue to look for ways to improve the document to make sure we are providing
stakeholders with the most appropriate information
National occurrence data publicly available:

Public Access to UCMR Results
Annual Consumer Confidence Reports (CCRs)
Required by 40 CFR ง141.153(d)(7) for community water systems (CWSs)
Detected unregulated contaminants, for which monitoring is required: the table(s)
must contain the average and range at which the contaminant was detected (i.e.,
measured > the UCMR MRL). The report may include a brief explanation of the reasons
for monitoring for unregulated contaminants
Example language: Unregulated contaminants are those for which EPA has not
established drinking water standards. The purpose of unregulated contaminant
monitoring is to assist EPA in determining the occurrence of unregulated contaminants
in drinking water and whether future regulation is warranted

Frequently Asked Question
Can a PWS use State-required PFAS monitoring results for UCMR 5?
PWSs may be able to conduct PFAS sampling that meets the needs of both State-required and UCMR 5
monitoring, with the understanding that UCMR 5 requirements must be met including:
PFAS samples must be analyzed by an EPA-approved UCMR 5 laboratory using EPA Method 533
and Method 537.1 to conduct the analysis for the respective PFAS, as required under UCMR 5
Sampling must take place during the 2023-2025 UCMR 5 monitoring period and follow UCMR 5
sampling frequency requirements
State-required MRLs must be equal to or lower than the UCMR 5 MRLs
EPA offers flexibility for PWSs to reschedule their UCMR 5 monitoring, and PWSs may do so to
coordinate it with their State-required monitoring. PWSs wishing to conduct "dual purpose" monitoring
(i.e., concurrently meeting the State and UCMR 5 needs) may contact their State or EPA, as
appropriate, if there are questions about whether both requirements are being met

Frequently Asked Question
Why do I need to report Zip Codes for all areas being served water by my PWS?
EPA will continue to collect U.S. Postal Service Zip Code(s) for UCMR 5, as collected
under UCMR 3 and UCMR 4, to support potential assessments of whether or not certain
communities are disproportionately impacted by particular drinking water
contaminants. The specification for this one-time reporting requirement is established
in 40 CFR 141.35(c)(1) and (d)(1) for large and small systems, respectively.

To distribution
FedEx
(800) 463-3339
Freeze ice packs for at least 72 hours prior to sam-
pling. Do not sample until ice packs are frozen solid.
Samples arriving at the lab too warm is the #1
reason for having to re-sample!
Only sample on Monday, Tuesday or Wednesday.
Check the entry point to the distribution system
sample location. Ensure that any supplies or tools
needed to open and flush the tap are available.
Samples must be shipped the same day they are
collected unless they are refrigerated overnight.
Arrange with FedEx to pick up your samples or plan to
drop them off at a staffed FedEx Express location.
^ Don't rinse out or overfill the bottles
There are preservatives in the bottles that need to be dissolved into the
sample (that's why they need to be shaken). Overfilling can dilute the
preservative concentration in the bottle.
Don't contaminate the bottles, lids, or samples
Refer to the kit lid for additional precautions to minimize the possibility
of contaminating your samples.
Do not touch the inside of the cap or bottle.
Do not touch the bottle to the faucet.
Do not place the lids in a pocket.
Set bottle lids face up on a clean surface while sampling.
(Q) Date all sample bottles using the supplied pen
The lab needs to know when the samples were collected so they are
analyzed before they expire.

Why must I collect these samples?
This sampling is required by EPA for public water systems. It is not voluntary. If you are
interested in learning more about the program, search for "UCMR5" online and visit EPA's UCMR
homepage.
What is being monitored for in the water samples?
Your drinking water is being tested for PFAS compounds and lithium.
I forgot/can't sample during my scheduled week. What should I do?
Call Great Lakes Environmental Center at (231) 525-0521 or email UCMR(3)GLEC.com
It's hot out. What should I do?
Chill the samples in a refrigerator for a couple hours before putting them in the shipping
container. Make sure the sample location on the bottles matches the sample location on the box
and paperwork when you're packing the kits for shipment.
How do I view my results?
To view your analytical results, inventory and schedule, log into the Safe Drinking
Water Accession and Review System (SDWARS) using the Central Data Exchange (cdx.epa.gov).

Abstract
EPA-HQ-OW-2020-0530
The Environmental Protection Agency (EPA) uses the Unregulated Contaminant Monitoring Rule (UCMR 5) to collect occurrence data
from public water systems 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) UCMR 5 provides the EPA and other interested parties with scientifically valid data on the
occurrence of selected contaminants In dnnking water This data set is one of the primary sources of nationally representative occurrence
data used to guide Agency decisions about emerging contaminants in the public drinking water supply
