The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for Labs
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	11
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

Sampling Locations - Cyanotoxins
One sample analyzed for
cylindrospermopsin and
anatoxin a using EPA Method
545
One sample analyzed for total
microcystins by EPA Method
546 (Adda ELISA)
Three samples collected at the
EPTDS for cyanotoxins (two for
potential microcystin analysis
and one for
cylindrospermopsin/anatoxin).
EPA Method 546 result
evaluated (minimum
reporting level for total
microcystins = 0.3 |ig/L)
November 2017
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 Labs
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 Coordinator(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	37
HAA and Indicator (TOC & Br) Resampling
•	HAAs: Resample only location(s) that did not produce valid
results for all 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

QC Tips
•	Smaller files are easier to troubleshoot
•	Keeping batches together makes file generation easier (e.g. everything
that is extracted together is analyzed together)
•	QC associated with "Approved" analytes/samples cannot be altered or
resubmitted. Submitting all field samples in a batch within one file can
make it easier to keep track
•	For sample types where a result is required (e.g. internal standards
reported as a percent recovery), the ResultBeiowMRL value should
always be "N"
•	For methods without an extraction, leave the extraction batch ID and
date null
•	Internal standard/surrogate recoveries and %CV are reported as a
percentage and should be rounded to the nearest whole number (e.g.
report 98.5% as 99% and 98.4% as 98%)
•	EPA recommends 3 significant figures for concentrations and 2
significant figures for standard deviations

QC Tips
•	Continuing Calibration Checks:
•	Report the analysis batch ID and date for the extraction batch ID and date fields
•	For methods where there is an option, report the IS value as compared to the most recently
analyzed CCC
•	Submit only valid data that is bracketed by passing CCCs
•	Method 546:
•	Each sample type should have a %CV reported with it
•	One CCC Low result is required and no other CCCs
•	Two LFB Mid results are required and no others
•	Two LRB results are required
•	Method 544: results cannot be reported when method 546 is

Timing of Reporting Results
•	Large systems
•	Laboratory posts results to SDWARS within 120 days of
sample collection
•	Systems review, approve and submit to State and EPA
within 60 days of laboratory's post
•	Small systems
•	EPA will still manage laboratory contracts for small
water systems
•	Laboratory posts results to SDWARS within 120 days of
sample collection (shorter for contracts)
•	Systems access their data in SDWARS

Risk Communication
Brenda Parris, LJSEPA
Overview
•	Reference Concentrations
•	Consumer Confidence Reports
•	Public Notification requirements
November 2017	U.S. Environmental Protection Agency	130
65 of 75
-------
The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for Labs
Risk Communication
•	UCMR reference concentrations are compiled from publically available EPA
sources
•	Review the supporting documentation referenced in the UCMR Data Summary
(updated quarterly)
•	Examples of secondary sources
•	Drinking Water Standards and Health Advisories
•	CCL 4 Contaminant Information Sheets
•	Human Health Benchmark for Pesticides (HHBPs)
•	Examples of sources where you can find additional information on the
critical study, other health effects, chemical properties, sources, exposure
etc.
•	Integrated Risk Information System (IRIS)
•	Office of Pesticides Program (OPP)
•	Office of Water - Drinking Water Contaminant Human Health Information
•	Agency for Toxic Substances & Disease Registry (ATSDR)
•	UCMR 4 Compendium
November 2017	U.S. Environmental Protection Agency	131
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	132
66 of 75
-------
The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for Labs
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
November 2017	U.S. Environmental Protection Agency	133
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)).

-------
The Fourth Unregulated Contaminant Monitoring Rule (UCMR 4): SDWARS Webinar for Labs
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 HAAS is regulated,
UCMR 4 HAAS results do not need to be reported on CCR,
•	If the UCMR 4 HAAS monitoring is scheduled to coincide
with the D/DBPR HAAS compliance monitoring (i.e., if the
monitoring serves both purposes), those results would be
reported on the CCR as D/DBPR data.
November 2017	U.S. Environmental Protection Agency	135
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.

Step 5: Upload File. In order to submit your analytical results file to SDWARS it must be in
text or XML format. Click on the text or XML links for help formatting your analytical results
file. After your file is in text or XML format click Choose File to browse for your file. Once
your file is selected click Upload. If your file is correctly formatted and there are no issues
with your data criteria, then the database will proceed to Quality Control (QC) review. If
your file doesn't meet the format criteria you will be redirected to a screen listing
formatting errors. Files that do not meet the format criteria cannot be loaded into SDWARS
and must be corrected before resubmission.
QC will only be processed once the file has passed the formatting criteria.
If your analytical results fail QC requirements, then an error message will be displayed.
Depending on the file specifications your data will be placed in hold or loaded into SDWARS
directly if your data passes all QC requirements. Data that doesn't pass QC requirements
will be automatically placed in hold and can be edited either in the Enter Data section or
via file correction.
We will take a closer look at file specifications and QC requirements later in this
presentation.

If your file doesn't meet the format criteria you will be redirected to a File Rejected screen
where you can review your file details. Correct your file and reload it. In order to proceed
with the Quality Control (QC) check of your data, you need to perform any corrections
indicated on the File Rejected page and then resubmit your file. Each error message will
display a code (seen here in blue at the top of each box) as well as the lines impacted and a
brief description. The screen will only show up to 25 errors. If there are more than 25
errors present, an email will go to your MyCDX inbox notifying you of this.

Once a file is successfully uploaded the File Upload Results screen will appear. Here you
can view the results of the file validation checks. Each Sample Kit ID can be reviewed by
selecting the corresponding tab on the left. A green check indicates that the data passed
the QC checks and you will see the drop down to approve data on the right under Status. A
red prohibition circle (as seen here) indicates that the data need to be reviewed and/or
edited. When selected, a blue link on the right under Status labeled QC Errors will produce
a pop-up window describing the errors (we will see this on the next screen).
You can expand or collapse the methods within a sample using the +/- arrows in the right
hand side.

Clicking the QC Errors link will produce this pop-up which contains QC Sampling Errors.
Each error is a brief description of the issues pertaining to that sample. Please note that if
batch QC is incorrect, the errors will be repeated for each analyte (within each sample) that
was impacted by that batch. In this example, method 200.8, the analytes fail because no
CCC Mid was reported. This also means all other analytes in samples that have the same
analysis batch ID will also fail and show this same error message.

Step 8: Review Data. You can search using the laboratory's Sample ID or by conducting an
Advanced Search, The Sample ID search function allows you to look for a specific
laboratory Sample ID. The Advanced Search function lets you limit your search by using
one more of the checkboxes under the Advanced Search section. Both the Collection Start
and End Date must be in the MM/DD/YYYY format as listed in the instructions. You can use
the wildcard percent symbol (%) to search for all of your data in those search fields that do
not have a drop-down list. Click Search to display up to 250 analytical results. If your search
exceeds 250 results, you must refine your search criteria to limit the array of data. Or click
Download Results to export all the data of your specified search.
Use the Review Data search function to review any data that your lab has submitted,
regardless of status. You will not be able to take any action on items that are in a review
status of Lab Approved or higher but you will be able to search for those results. Lab hold
data is also viewable through this search. You can additionally search by status if needed.

This view does look similar to the view in the Enter/Edit Data section but the key
differences are that the possible search results are different (this section can display data in
all statuses as we just discussed). You cannot edit any data in this view, only approve data
that is still in lab hold and has passed QC. Select a Status for each analytical result. The
Approve All button will set all lab hold statuses on the page to Approve.
Data that indicates Range Check has a Range Check Violation and must be reviewed/edited
in order to be lab approved.
