Enacted in 1974, SDWA authorized the Environmental Protection Agency (EPA)
to set enforceable health standards for contaminants in drinking water
National Primary Drinking Water Regulations (NPDWRs)
The 1986 SDWA amendments were the basis for the original "UCM" program
State drinking water programs managed the original UCM program
Public water systems (PWSs) serving >500 people were required to monitor

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

PWS Types
Public Water System (PWS): provides water for human consumption through
pipes or other constructed conveyances to at least 15 service connections or
serves an average of at least 25 people for at least 60 days a year
Community Water System (CWS): PWS that supplies water to the same population
year-round
Non-Transient Non-Community Water System (NTNCWS): PWS that supplies water
to at least 25 of the same people at least six months per year but not year-round
(e.g., schools)
Transient Non-Community Water System (TNCWS) (not generally included in UCMR
sampling and not included in UCMR 5): PWS that provides water where people do
not remain for long periods of time (e.g., gas stations, campgrounds)

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)
Assessment Monitoring is the only tier under UCMR 5

Assessment Monitoring
Primary objective is to determine national contaminant occurrence in PWS-supplied drinking
water for the purpose of estimating national population exposure
Primary tier and largest in scope
Generally relies on analytical methods that use more common techniques and are expected to
be widely available
Consistent with the AWIA provisions, monitoring for UCMR 5 includes:
Small
Nationally representative sample of 800 systems serving <3,300 people
Census of systems serving 3,300 to 10,000 people, if they are notified and confirmed by EPA
Large
Census of systems serving >10,000 people

PWS Notifications
Notifications were sent to ALL PWSs subject to UCMR 5 (~10,300)
Notifications informed PWSs of their UCMR requirements and included:
Instructions on how to access EPA's web-based data reporting system, the Safe
Drinking Water Accession and Review System 5 (SDWARS 5)
Actions that ALL PWSs must take in SDWARS 5 to prepare for their monitoring
Most PWSs received their notification through email from UCMR@epacdx.net during
the week of January 18th, 2022. Please check your junk/spam folders. Emails were
sent to multiple contacts at each PWS, if available.
PWSs without a valid email address were physically mailed a notification the week of
February 22, 2022. The letter was addressed to the PWS, not a specific person.

Small PWS Notifications - Confirmed
EPA has funding available to support monitoring at the representative national
sample of 800 PWSs serving <3,300 people and has notified those systems that
their participation is confirmed
EPA also has funding available to support monitoring at ~400 randomly selected
PWSs serving 3,300 to 10,000 people and has similarly notified those systems
Prioritizing these systems allows EPA to ensure a national random sample for
small PWSs serving ^10,000 people, irrespective of participation by other small

Other Small PWS Notifications-Tentative
As described in the final UCMR 5, EPA's ability to support monitoring at the other small
PWSs serving 3,300 to 10,000 people depends on additional appropriations in fiscal
year 2022 and future years. With the expectation that those systems will participate in
UCMR 5, but allowing for the funding uncertainty, EPA has notified those PWSs of their
participation in January and February 2022. Those notifications included the following
additional information:
Those PWSs will be notified approximately 6 months prior to their scheduled sampling year
to confirm their participation in UCMR 5 (i.e., by July 1, 2022, for 2023 sampling; by July 1,
2023, for 2024 sampling; and by July 1, 2024, for 2025 sampling)
Those PWSs must still prepare for their tentatively scheduled sampling and must complete
the pre-sampling reporting requirements in SDWARS 5 by December 31, 2022

Sampling Schedules
EPA initially drafted schedules for large and small PWSs

small PWSs during review of State Monitoring Plan
Large PWSs have opportunity to review and modify their schedule through
December 31, 2022
Starting in 2023, large PWSs must contact EPA at UCMR Sampling Coordinator(a)epa.gov to
request schedule changes and provide a reason

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 M
-------
The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - March 2022 Meeting Presentations for Implementation
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.
pM United States

mI Agency
Frequently Asked Question
I am a wholesaler with no retail population, am I subject to UCMR 5?
No. UCMR 5 applies to public water systems (PWSs), defined as systems that
provide water for human consumption through pipes, or constructed conveyances,
to at least 15 service connections or that regularly serve an average of at least 25
individuals daily at least 60 days out of the year. Under CFR 141.35(a), as revised
by EPA for UCMR 5, a PWS' "population served" is defined as the retail population
served directly by the PWS as reported to the Federal Safe Drinking Water
Information System (SDWIS/Fed).

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.

mI Agency
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(a)glec.com) with additional questions/concerns.

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - March 2022 Meeting Presentations for Implementation
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.
pM United States
Environmental Protection
mI Agency
Frequently Asked Question
Will EPA provide materials specific to sampling procedures for PFAS?
The Agency will prepare outreach material for PWSs on PFAS sampling for UCMR 5,
including instructions to reduce cross-contamination and demonstrating UCMR 5
sampling procedures. EPA will provide this material in the UCMR 5 Laboratory
Manual, SDWARS 5 User Guide, and in future stakeholder meeting materials.

(GWRMP) Program
Applications from PWSs are now being accepted
PWSs with multiple ground water EPTDSs can sample at representative locations rather
than at each EPTDS, with EPA approval
A representative EPTDS is associated with a ground water well that:
Is in close proximity to and draws from the same source as the wells it represents (i.e., same
aquifer)
Is representative of the highest annual volume and most consistently active wells
Will be in use at the scheduled sampling time

Frequently Asked Question
I have a consecutive connection with multiple connections from the
same wholesaler. What do I do?
PWSs that purchase water with multiple connections from the same wholesaler
may select one representative connection from that wholesaler, as specified in 40
CFR 141.40(a)(3) Table 1, footnote c. The entry point to the distribution system
(EPTDS) representative sampling location must be representative of those that
receive the highest annual volume. If the connection selected as the
representative EPTDS is not available for sampling, the PWS must sample an

Frequently Asked Question
How does a PWS establish a GWRMP for UCMR 5?
There are three ways for a PWS to establish a GWRMP for UCMR 5. All three require the PWS to initiate
the process six months prior to the PWS's scheduled sample collection date by sending an email to
UCMR Sampling Coordinator(a)epa.gov.
1) The PWS may use a GWRMP from a previous UCMR cycle by emailing EPA to confirm this intention and
that no significant changes have occurred to the ground water EPTDSs since the GWRMP was approved.
2) The PWS may request to modify a previous GWRMP if significant changes have occurred to the ground
water EPTDSs. The PWS must email EPA all appropriate information supporting the changes, which may
include a revised site map or historical water quality data, consistent with the criteria outlined in the
instructions for preparing a GWRMP (available in the docket).
3) The PWS may submit a proposal for a new GWRMP by sending an email to EPA listing the proposed
representative ground water sampling EPTDSs and containing all appropriate supporting information,
consistent with the criteria outlined in the GWRMP instructions.

Frequently Asked Question
Why do I need to report Zip Codes for each service area?
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.

Frequently Asked Question
How does EPA determine reporting limits for UCMR analytes?
EPA establishes the minimum reporting level (MRL) using data from multiple laboratories performing "Lowest
Concentration Minimum Reporting Level" (LCMRL) studies to identify their capability. The MRL is the minimum
quantitation level that, with 95% confidence, can be achieved by capable analysts, by at least 75% of the
laboratories nationwide using a specified analytical method. Each single-laboratory LCMRL is the lowest true
concentration for which the future recovery is predicted to fall, with high confidence (99%), between 50 and
150% recovery
Simultaneous application of precision and accuracy
Established to achieve quality and consistency across all UCMR laboratories, while allowing for appropriate
national laboratory capacity
MRLs are generally established as low as is feasible, typically lowerthan current health reference levels (HRLs)
and health advisories (HAs)
EPA will consider adjusting MRLs if there is confirmed and recurring evidence that an MRL is
unattainable/impractical

Frequently Asked Question
Can laboratories use EPA Method 200.8 instead of EPA Method
200.7 to analyze UCMR 5 samples for lithium?
No. EPA Method 200.8 is not validated for lithium analysis in drinking water and
thus cannot be used to meet the requirements of UCMR 5 monitoring.
pM United States
Environmental Protection
mI Agency
Frequently Asked Question
When will the request for contract proposals for the small-system sample analyses be announced?
EPA engaged the laboratory community early in the development of UCMR 5, held public meetings, and
offered five PT studies. All of these opportunities have been communicated to the laboratories to
encourage participation early in the approval process. EPA released the request for proposal on
February 17, 2022, with proposals due from laboratories on March 17, 2022. EPA expects demand for
laboratory support to increase significantly based on the greater number of PWSs participating in
UCMR 5. EPA estimates that the number of participating small water systems will increase from the
typical 800 to approximately 6,000. In preparation for this increase, EPA has solicited proposals and will
award contracts to laboratories to support small-system monitoring prior to the end of the PT program.
As in previous UCMR programs, EPA expects that laboratories awarded contracts by EPA will be required
to first be approved to perform all methods.

Prior to the start of UCMR 5 sample collection in January 2023, EPA will
publish a "Reference Concentration" document to summarize the publicly
available health information from EPA resources for the UCMR 5 contaminants
EPA will continue to look for ways to improve the document to make sure
we are providing stakeholders with the most appropriate information and
messaging materials
After monitoring starts, EPA will update the NCOD and publish a Data
Summary approximately quarterly (posted at https://www.epa.gov/dwucmr)
The Data Summary will summarize the NCOD results at a national level
(e.g., the number of PWSs with results above the MRL and/or reference
concentration) and provide data field definitions

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
w
What efforts will be made to assist with risk communication for PFAS?
1. Information Compendium for Contaminants for UCMR 5
A summary of the contaminant prioritization process and contaminant-specific information (e.g., health effects) that EPA gathered for
the UCMR 5 analyte list (https://www.regulations.gov/document/EPA-HQ-OW-2020-0530-Q126).
2. Reference Concentrations
EPA intends to publish (and routinely update, as new data becomes available) "reference concentrations" on the UCMR website prior to
UCMR 5 monitoring (during 2022). The reference concentrations are based on publicly-available health information from EPA sources to
provide context around results above the MRL. MRLs are based on the capability of the analytical method and are typically lower than
the current health values. This ensures that the occurrence data reported to EPA will support sound decision making, including those
cases where new health effects information might lead to lower health values (https://www.epa.gov/dwucmr/occurrence-data-
unregulated-contaminant-monitoring-rule).
3. Template to Communicate Detections
The Agency intends to provide a template for PWSs to consider using in communicating with their customers about the detection of
PFAS in drinking water and provide other supporting material as risk-related information becomes available. PWSs should be aware that
some States may have requirements for communicating PFAS monitoring results to consumers and/or reporting them to the State.

More Details ป
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
