The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for PWSs
Objective of UCMR Program
• Collect nationally representative occurrence data for
unregulated contaminants that may require regulation
under the SDWA
•	Consider data collected as part of future EPA decisions on
actions to protect public health
•	Provide data to States, local governments and to the public
for their use in decisions regarding public health protection
National occurrence data publically available:
https://www.epa.gov/dwucmr/occurrence-data-unregulated-
contaminant-monitoring-rule
November 2017	U.S. Environmental Protection Agency
UCMR Approach
•	UCMR approach relies on using one or more of 3
monitoring tiers
•	Assessment Monitoring (List 1)
•	Screening Survey (List 2)
•	Pre-Screen Testing (List 3)
•	Based on:
•	Availability and complexity of analytical methods
•	Laboratory capacity
•	Sampling frequency
•	Relevant universe of PWSs
•	Other considerations (e.g., cost/burden)
•	UCMR 4 only involves Assessment Monitoring

545
One sample analyzed for total
microcystins by EPA Method
546 (Adda ELISA)
Three samples collected at the

potential microcystin analysis
and one for
cylindrospermopsin/anatoxin).
EPA Method 546 result
evaluated (minimum
reporting level for total
microcystins = 0.3 |ig/L)
ELISA result >0.3 [ig/L
ELISA result <0.3 |ig/L
EPTDS result reported to EPA
and the 544 sample will not
be analyzed for this particular
sampling event
EPTDS result will be reported to EPA
and the other microcystin sample
must be analyzed using Method 544
to identify particular microcystin
congeners
November 2017	U.S. Environmental Protection Agency	27
Cyanotoxin Resampling
• If a sample is invalid, it should be resampled if it can be
re-collected prior to the next scheduled sampling event
(~2 weeks). In those cases, where it proves impractical
to resample, PWSs should enter a comment in SDWARS
outlining the circumstances of the missing result.
•	Example: A PWS sample has a 546 (ELISA) result > 0.3 (ag/L.
but method 544 is invalid. If re-collection cannot happen prior
to the next scheduled sampling event, a resample for 544 is
not required. The results for method 546 should be reported.
•	Example: A PWS sample for method 546 is invalid. If re-
collection can happen prior to the next scheduled sampling
event, it is recommended to resample both 546 and 544.

The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for PWSs
HAA Sampling Locations: Approach
•	Systems must:
•	Input inventory into SDWARS based on current D/DBPR monitoring
requirements and status (routine or reduced)
•	Use inventory from first sampling event for subsequent sampling
events
•	Comply with the UCMR 4 frequency requirements even if on reduced
D/DBPR monitoring
•	Systems can:
•	Take UCMR 4 HAA/indicator samples and D/DBPR compliance samples
at the same time
• PWSs can change their sampling schedules in SDWARS without EPA approval
priorto December 31, 2017. After that, you must contact
UCMR Sampling Cooidinator(5>epa.gov
•	Use one lab for UCMR 4 and D/DBPR analysis IF the UCMR 4 approved
lab is also certified to analyze compliance samples (using EPA Method
552.3 or 557) in your State
November 2017	U.S. Environmental Protection Agency	31
HAA Indicator Sampling Locations: Approach
• Sample for TOC and bromide at:
•	Source water influent locations representing untreated
water entering the water treatment plant (i.e., a
location prior to any treatment)
•	The same time as HAA samples (or as close as is
feasible)
•	Entry points associated with 100% purchased water
(consecutive connections) do not need to be sampled
for TOC and bromide

TOC and Bromide Sampling Locations
•	GW Systems not subject to D/DBPR TOC sampling
requirements
•	Take UCMR 4 indicator samples at ALL influents
entering treatment train
•	Can use combined taps prior to treatment
•	if have an approved GWRMP only need to take
indicator samples representing those EPs
•	Only take indicator samples from active wells at time of
collection
* Add a comment in SDWARS for the non-active locations
November 2017	U.S. Environmental Protection Agency
HAA and Indicator (TOC & Br) Resampling
•	HAAs: Resample only location(s) that did not produce valid
results for ali analytes
•	TOC and Br: Resample only location(s) that did not produce
valid results
•	Example: A PWS has four HAA distribution system locations
and two TOC and Br source water locations. One of the HAA
locations is invalid and one of the TOC locations is invalid.
Only resample those locations that are invalid.
• The sampler should re-collect the HAA and TOC samples at the
same time (or as close as is feasible).
•	Example: The same PWS (described above) only has an
invalid TOC sample at one location. Only resample that TOC
location.

Analyzing TOC and Bromide Samples
• Laboratory Approval Registration closed February 21,
2017 (except TOC and bromide)
•	Laboratories (including PWS labs) that only wish to analyze
TOC and/or bromide may apply for authorization through
December 1, 2017
•	These PWS laboratories must complete registration and
submit documentation that they are authorized to analyze
TOC and/or bromide compliance monitoring samples under
the Stage 2 D/DBPR by December 15, 2017
•	These PWS laboratories will receive a CRK separately from
their PWS CRK to enter their TOC and/or bromide data into
SDWARS4
•	UCMR Lab Approval (Sepa.gov
November 2017	U.S. Environmental Protection Agency	39
Two Types of Representative Sampling
• All approved representative locations must be loaded
into SDWARS by PWS no later than December 31, 2017
*	Ground Water Representative Monitoring Plans (GWRMPs)
- large ground water systems with multiple EPTDSs can
sample at representative sampling locations rather than at
each EPTDS if prior approval is received
• GWRMP sampling plans and renewals are due to
UCMR Sampling Coordinator(5)epa.gov
•	Representative Connections - systems that purchase water
with multiple connections from the same wholesaler may
select one representative connection from that wholesaler

The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for PWSs
NOTIFICATION LETTER
January 3, 2017

RE: Unregulated Contaminant Monitoring for Surface Water (SW) and Ground Water Under the Direct Influence of Surface Water (GWUDI) Systems Seiving over 10,000 Persons
Dear Public Water System:
The purpose of this letter is to notlty your public water system (PWS) of its monitoring requirements under the revision to the Unregulated Contaminant Monitoring Rule (UCMR4). The U.S.
Environmental Protection Agency (EPA) published the final rule detailing the upcoming monitoring of unregulated contaminants at PWSs on December 20, 2016, establishing a new list of
contaminants to be monitored and the conditions for that monitoring. This rule benefits public health by providing EPA and other interested parties with scientifically valid data on the national
occurrence of selected contaminants in drinking water. This dataset is one of the primary sources of information on occurrence, levels of exposure and population exposure EPA uses to develop
regulatory decisions for contaminants in the public drinking water supply.
Under the UCMR4, all community water systems and non-transient, non-community water systems serving more than 10,000 persons must participate in Assessment Monitoring (AM). Our
tecoids indicate thot your surface watei system must monitoifoi .ill List 1 contaminants: metals, pesticides, semi-volatile organic chemicals (SOCs). alcohols (AM 1). halo acetic
acids (HAAs) (AM 2). and cyanotoxius (AM 3)
What miistyoui PWS complete in SDWARS before Decemhei 31. 20177
Similar to reporting under UCMR3, PWSs will use the Central Data Exchange (CDX) (httpsJcdx.epa.gov/) to access the updated version of the Safe Drinking Water Accession and Review
System (SDWARS4). PWSs are required to:
enter your official and technical contact information;
•	review and, if necessary, update your sample location data by adding missing locations (e.g., Stage 1 and Stage 2 Disinfectants and Disinfection Byproduct Rules sampling
locations for the HAAs), indicating ineligible locations or editing basic information about the locations; and
¦	review and, if you wish, revise your monitoring schedule assigned by the EPA.
What miistyoui PWS do dining UCMR4 monitoiing?
Your PWS must ensure that samples are properly collected, packaged and shipped to a UCMR4 EPA approved laboratory. Your PWS is also responsible for providing the data elemenls required
for each sampling location (e.g., disinfection type, treatment type etc.) in SDWARS. Once data are posted to SDWARS by your laboratory, your PWS will have 60 days to review and act upon
these results. If you choose not to review these results in this time frame, they will be considered final. Additionally, community water systems are required to address their UCMR monitoring
results in their annual Consumer Confidence Report (CCR) whenever unregulated contaminants are detected (https://wwv.epa.gov/ccr).
Where can I find moie information about UCMR4?
EPA recommends that you review the complete rule and supporting reference materials addressing UCMR4 at https://www.epa.gov/dwucmr/fourth-unrequlaled-contaminant-monltorinq-njle.
•	The "Revisions to the Unregulated Contaminant Monitoring Rule (UCMR4) for Public Water Systems and Announcement of Public Meeting" [EPA-HQ-OW-2015-0218; FRL-9956-
71-O.W);
¦	UCMR4 implementation fact sheets: Metals, Pesticides, SOCs, and Alcohols (AM 1), Haloacetic Acids (HAAs) (AM 2), Cyanotoxins (AM 3) and General Information;
•	EPA approved laboratories for UCMR4 (the list will be updated as additional laboratories are approved);
•	Outreach materials and announcements for stakeholder meetings and trainings.
Analytical results from UCMR are publically available in the National Contaminant Occurrence Database (NCOD); for a summaty of the NCOD results, tips for querying NCOD, and health effects
information please refer to the UCMR Data Summary document.
This notification letter is being sent to you as the official representative of this PWS. If someone else at your PWS needs this information, such as the plait operatoi. please provide
them with a copy of this letter. Your cooperation in meeting these lequiiements is appieciated.
F or questions regarding SDWARS or CDX, please contact the CDX Help Desk at 1-888-890-1995. For implementation or general questions, please contact the UCMR M essage Center at
1-800-949-1581 or UCMR4@glec.com. Thank you foryour cooperation.

Risk Communication
•	The reference concentration:
•	Does not represent an "action level" (EPA requires no
particular action based simply on the fact that UCMR
monitoring results exceed draft reference
concentrations)
•	Should not be interpreted as any indication of Agency
intent to establish a future drinking water regulation at
this or any other level
•	Decisions whether or not to regulate the
contaminant in drinking water will continue to be
made following the Agency's Regulatory
Determination process
November 2017	U.S. Environmental Protection Agency	121
Risk Communication
•	The intent of the UCMR reference
concentrations is to provide, where
possible, context around the detection
of a particular UCMR contaminant
above the MRL
•	EPA will continue to look for ways to
improve the UCMR Data Summary to
make sure we are connecting you to the
most appropriate information and
messaging materials
•	Follow State, Consumer Confidence
Report and Public Notification
requirements

The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for PWSs
Public Access to UCMR Results
• UCMR results can be viewed by the public:
•	At https://www.epa.gov/dwucmr
•	In annual Consumer Confidence Reports (CCRs)
• Required by §141.153(d)(7) Community water systems (CWSs)
•	Unregulated contaminants detected during UCMR monitoring must be
reported in a CWS's CCR following the year they were received. For
additional information see 40 CFR Subpart 0 and
https://www.epa.gov/ccr.
•	Detected unregulated contaminants, for which monitoring is required
(except Cryptosporidium), the table(s) must contain the average and
range at which the contaminant was detected. The report may include
a brief explanation of why the CWS is monitoring for unregulated
contaminants and this explanation can provide context for reference
concentrations.
•	TOC and bromide are not UCMR 4 contaminants (only indicators) (40
CFR 141.40(a)(3) table 1 footnote e), and are not required to be
reported on a CCR (40 CFR 141.35(b)(1)).
November 2017	U.S. Environmental Protection Agency	123
Public Access to UCMR Results: CCR
•	Recommend that the UCMR 4 results (including UCMR 4
HAA6 Br and HAA9 results) be reported in the CCR in a
section separate from the compliance-monitoring results
for regulated contaminants.
•	Since CCR requirements for UCMR apply to detection of
unregulated contaminants, and since HAA5 is regulated,
UCMR 4 HAA5 results do not need to be reported on CCR.
•	If the UCMR 4 HAA5 monitoring is scheduled to coincide
with the D/DBPR HAA5 compliance monitoring (i.e., if the
monitoring serves both purposes), those results would be
reported on the CCR as D/DBPR data.

-------
The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for PWSs
Example CCR 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.
Preparing Your Drinking Water Consumer
Confidence Report Guidance for Water
Suppliers: "Unregulated contaminant
monitoring helps EPA to determine where
certain contaminants occur and whether the
Agency should consider regulating those
contaminants in the future." EPA is exploring
possibilities for clearer risk communication.
November 2017	U.S. Environmental Protection Agency
Public Access to UCMR Results
• In Public Notification
•	Required by §141.207 for CWS and NTNCWS
•	PWSs must notify persons served of the availability of the
results no later than 12-months after monitoring results are
known
•	Follows Tier 3 public notice §141.204(c), (d)(1) and (d)(3)
• Special requirement- notice must identify a person and the
telephone number to contact for information on monitoring
results
•	CWSs may include their public notice within their CCRs

November 2017	U S environmental Protection Agency	58
You must complete every field marked with an asterisk (*). All contact information is
confidential and is only available to regulatory authorities. You must click Save Changes for
the information to be added to the database. Use the Receive Auto Email Notifications(s)
checkboxes at the bottom of the screen if you wish for the contact to receive email
message reminders about certain critical tasks such as schedules, posted data and missing
additional data. These contacts will not have accounts in SDWARS and will not
automatically be a PWS representative in SDWARS. You can nominate your contacts so they
can additionally take actions and review data in SDWARS.
Please note there are three contact types for each PWS account. An individual PWS is
required to have at least 2 contacts (one official and one technical).
Mailing information is not required but EPA appreciates this information.

Step 4: Add Inventory. There are 3 options for adding your inventory which can seen here
in red boxes. When adding your inventory please ensure that all required sample locations
for UCMR 4 are included which means all entry points (EP) to the distribution system and
for those PWSs monitoring the HAAs, their stage 2 distribution system locations and intakes
(IN) prior to treatment. An intake sample is not required for consecutive connections.
There is some light blue functional text that reads (more...) next to the red arrow on the
top right. If you click on that, additional instructions on how to add and review inventory
will pop-up.
As a reminder, you may add and edit your inventory through SDWARS until December 31st,
2017. After that date, you will be able to review the inventory and make minor edits (which
we will see in a few slides) but adding and removing locations should be done through the
UCMR Sampling Coordinator.
