40 CFR 141,35
SDWARS 5 PWS users will get an automated email notification when analytical results are posted
Small PWS Analytical results
Per contracts with EPA, laboratories post results to SDWARS within 60 days of sample collection
EPA will review results, pay the laboratory, and approve the small PWS data
Results then become viewable in SDWARS to PWS, State, and others in EPA
Large PWS Analytical results
Posted to SDWARS by the large PWS's contracted laboratory within 90 days from the sample collection date
The large PWS is responsible for ensuring their laboratory posts the results to SDWARS in this time
Large PWS has an opportunity to review and approve/reject data in SDWARS within 30 days from when the
laboratory posts the data
Following PWS approval, or expiration of the 30-day optional review period, the results become viewable
in SDWARS for State and EPA review

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - Accessing Data and Communicating Results
"Health-Based Reference Values" Document
The purpose of this document is to provide context around UCMR 5 results in relation to EPA
established minimum reporting levels (MRLs) and, if available, health-based reference values, or
"HBRVs" (i.e., reference concentrations and reference doses [RfDs])
It is considered a "living document" that will be routinely updated as new health-based information
becomes available
EPA will soon propose a National Primary Drinking Water Regulation (NPDWR) for PFAS; the Agency is using
the 2022 EPA lifetime health advisory (HA) levels for PFAS in drinking water as "reference concentrations"
for UCMR 5 and will update the values when the final NPDWR is promulgated
UCMR is an occurrence study and EPA often does not have full knowledge of the health effects for
these unregulated contaminants
The document "Health-Based Reference Values for UCMR 5" is publicly available at:

UCMR 5 Minimum Reporting Levels (MRLs)
Calculated using analytical data from multiple laboratories that participate in EPA's
MRL-setting studies
The goal of the MRL approach is to create a consistent, high-quality UCMR dataset using
results reported by many laboratories across the country
MRLs are the lowest concentrations that laboratories may report to EPA during UCMR 5
monitoring
MRLs are not associated with contaminant health effects information
Some MRLs are below lifetime HA levels for PFAS (e.g., PFBS, Gen X chemicals) and
others are above (e.g., PFOS, PFOA)

Health-Based Reference Values (HBRVs)
Depending on the available health and toxicological information for a UCMR 5 contaminant,
a reference concentration (e.g., a lifetime HA level, health reference level [HRL]) in drinking
water may be available
The current reference concentrations are derived using a reference dose (RfD) (i.e., a non-
cancer endpoint) and additional assumptions about body weight and drinking water intake

indication of future Agency actions

Lithium is on EPA's CCL 5, a priority list of drinking water contaminants that may require future regulation under SDWA
Available data for lithium demonstrated a relatively high occurrence above the health reference level (HRL) compared to
other contaminant candidates, supporting the inclusion of lithium on CCL 5 and in UCMR 5 monitoring
vvEPA

Agency
Office of Water
CCL 5 Health Reference Level (HRL) for Lithium
The CCL program derives HRLs for screening purposes using available data
HRLs are not final determinations about the level of a contaminant in drinking water that is necessary to protect
any particular population and, in some cases, are derived prior to development of a complete exposure assessment
During its development of CCL 5, EPA derived an HRL for lithium in drinking water of 10 ng/L, based upon EPA's
2008 Provisional Peer-Reviewed Toxicity Value (PPRTV) assessment
The provisional RfD is based on adverse health effects at therapeutic doses which are much higher than estimated
average intake from drinking water or dietary sources
At the time of publication of the PPRTV assessment, research had not addressed the health effects of lithium at
average environmental intake levels
The CCL 5 Rapid Systematic Review of literature (conducted October 2019) identified 46 animal toxicological and 189 human
epidemiological studies potentially relevant to lithium; these studies may provide information related to quantifying dose-
response relationships between lithium exposure and adverse health effects, but further evaluation is needed

EPA Lifetime Health Advisories (HAs) for PFAS
Lifetime HAs are designed to protect all people, including sensitive populations and life
stages, from adverse health effects resulting from exposure throughout their lives to
contaminants in drinking water
Calculated to offer a margin of protection against adverse health effects
Take into account other potential sources of exposure (e.g., food, air, consumer products)
Establish levels at or below which no adverse effects are expected
HAs are non-enforceable and non-regulatory
Provide technical information to PWSs, States, and public officials on health effects, analytical
methods, and treatment technologies
States may have their own advisory levels or regulations for PFAS that PWSs will need to be
aware of

Additional State Access to Small PWS Results:
Early Availability of Preliminary UCMR 5 PFAS Results Above HA Levels
* EPA established contracts with laboratories to analyze UCMR 5 samples from small PWSs (i.e., EPA pays
for sample analyses and shipping) and receives the laboratory-approved preliminary results
EPA will provide States with preliminary UCMR 5 PFAS results above an EPA HA level before results are
available in SDWARS and encourages the sharing of this early information with the small PWSs
EPA's strategy for communicating preliminary results from small PWSs is intended to work in conjunction with
State information and will be updated as new information becomes available
It is still important for States to have an active SDWARS account to view all PWS results, inventory, sampling
schedules, and receive direct communications from EPA
Large PWSs contract directly with laboratories to analyze their UCMR 5 samples and have access to their results
prior to EPA. Large PWSs can also make arrangements with their contracted laboratory for "early" notification
(i.e., before their laboratory posts the results to SDWARS).

Overview of PWS and State Access to Small PWS Results
OGWDW emails EPA Region preliminary PFAS results above an HA level in a
report for each State on a monthly basis (possibly starting in March 2023
depending on the data received)
Region provides State with preliminary reports and supplemental resources
State
Shares preliminary report(s) from EPA and/or populated template with
the small PWS, as appropriate (PWS is automatically notified via SDWARS
when EPA-reviewed results are available)
Accesses EPA-reviewed results via an active SDWARS account
Small PWS
Receives an early notification via State about preliminary PFAS
results above HA levels, as appropriate
Receives real-time notification via SDWARS about EPA-reviewed

Starting mid-2023, EPA will update the National Contaminant Occurrence
Database (NCOD) with UCMR 5 results and publish a "Data Summary"
approximately quarterly at the web page shown below
The Data Summary will include the NCOD results at a national level (e.g., the
number of PWSs with results above the MRL and above HBRVs)
The initial Health-Based Reference Values document (see slide 51) will be
incorporated into the quarterly UCMR 5 Data Summary

The Fifth Unregulated Contaminant Monitoring Rule (UCMR 5) - Accessing Data and Communicating Results
Other Consumer Access to Results:
Consumer Confidence Reports (CCRs)
Annual Consumer Confidence Reports (CCRs)
Required by 40 CFR 141.153(d)(7) for community water systems (CWSs)
For required unregulated contaminant monitoring: the CCR table(s) must contain the average and range at which
the contaminant was found (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
EPA's CCR Compliance Help web page provides guidance and tools for CWSs
Water Research Foundation's UCMR 5 Toolkit includes CCR guidance and example language (see slide 80)
CWSs are responsible for being aware of and complying with their State's requirements, if any

Public Notification (PN)
Required by 40 CFR 141.207 for all PWSs (i.e., CWSs and NTNCWSs) subject to UCMR
PWS must notify people served of the availability of all UCMR results no later than 12 months after they are known
Follows Tier 3 PN prescribed in 40 CFR 141.204 (c), (d)(1), and (d)(3)
Special notice requirement must identify a person and the telephone number to contact for information on the
unregulated contaminant monitoring results
CWSs may include their public notice within their CCRs if timing and delivery requirements are met
EPA's PN Compliance Help web page has resources for PWSs including a handbook and Tier 3 PN template

PFAS and Water
Water quality is regulated to protect public health and
drinking water quality is public information. Thus,
water often provides the first clues about
health-related trends we need to pay attention to.
Water also connects all of us. Vast as it may seem, our
world is a closed system There is no such thing as
"new" water. All water is shared, and it flows in and
out of streams, rivers, oceans, and each of us Along
the way. it often carries the things that we put in it.
including chemicals like PFAS
Water utilities are responsible for maintaining water
quality according to regulations while also keeping
drinking water affordable Treatment to remove PFAS
from water can happen at utilities and in our homes -
using technologies like activated carbon and reverse
osmosis - but this treatment can be expensive Our
country's regulatory process helps make sure we are
delivering the safest water at a cost that is affordable
to all Your water utility's website is the best place to
find reliable information about relevant regulations
and our local drinking water quality.
