FEDERAL-STATE TOXICOLOGY RISK ANALYSIS COMMITTEE

What Is FSTRAC?

FSTRAC's mission is to strengthen relationships and cooperation among the EPA, states and Tribes
through the exchange of technical information primarily regarding water-related human health and
risk assessment and also share information on ecological effects related to water quality criteria. FSTRAC
is composed of current representatives from governmental agencies (state, Tribal, federal health and envi-
ronmental agencies, and other regulatory authorities) and representatives from the Association of State
Drinking Water Administrators (ASDWA) and the Association of Clean Water Administrators (ACWA).
The goal of FSTRAC is to share information that supports the development of well-rounded, integrated
approaches to effects assessment, risk assessment, risk management, risk communication, and standard-set-
ting for drinking water, groundwater, and surface water contaminants. Specific objectives of FSTRAC
include:

•	To foster cooperation, consistency, and an understanding of goals and problems in human health and
ecological risk assessment for contaminants in water.

•	To allow the exchange of technical information, including toxicity/exposure data and analysis, and
methodologies and assumptions related to the development and implementation of regulations, criteria,
advisories, and other toxicity values under the Safe Drinking Water Act and the Clean Water Act, and
other state and Tribal rules and policies as applicable.

•	To allow the exchange of information on research priorities and results.

•	To share science policy concerns regarding water-related human health and ecological risk assessment.

Recent Webinars

FSTRAC holds several webinars each year to share
information through presentations and discussions
regarding human health risk analysis and water qual-
ity issues.

the Federal Insecticide, Fungicide, and Rodenticide
Act (FIFRA)/Clean Water Act (CWA) harmonized
approach for pesticides; releasing draft human health
criteria for perfluorooctanoic acid (PFOA), perfluo-
rooctane sulfonate (PFOS), hexafluoropropylene oxide
dimer acid (HFPO-DA), and perfluorobutane sulfonic
acid (PFBS); and releasing a draft risk assessment for
PFOA and PFOS in biosolids. Ms. Flaherty mentioned
that additional OST/HECD priorities for FY 2025
include providing support for aquatic life criteria
development efforts (including metals Cooperative
Research and Development Agreement [CRADA]
bioavailability models and criteria for nickel, lead,
zinc, and cobalt), updating the Metals Aquatic Life
Criteria and Chemistry (MetALiCC) map to include
state water chemistry data, Safe Drinking Water Act
(SDWA) processes (including Contaminant Candidate
List 6, Regulatory Determination 5, and Six Year
Review 4), state-specific nutrient criteria develop-
ment projects, EPA's National Harmful Algal Blooms
(HABs) Program, and biocriteria priorities (including
streamlining development and implementation of bio-
logical condition gradients).

EPA Technical Support Materials (TSM): Developing
Alternative Recreational Criteria for Waters Contaminated
by Predominantly Non-Human Fecal Sources (July Revised
Version) (presented by John Ravenscroft, HECD/OST/OW/
EPA). EPA developed the TSM for predominantly
non-human fecal sources to provide scientifically
defensible, equivalently health protective alterna-
tive values for E. coli and enterococci that reflect the
potential risk from predominantly the non-human
fecal sources. Mr. Ravenscroft noted that this alter-
native method was developed because the health
data used to support the EPA's 2012 Recreational
Water Quality Criteria (RWQC) were collected in
waterbodies predominantly impacted by human fecal
contamination and that non-human fecal contam-
inated water can result in lower human health risk
compared to human fecal contaminated waters at the
same level of the culturable fecal indicator bacteria
(FIB) E. coli and enterococci. Mr. Ravenscroft noted
that these alternative criteria developed using the TSM
would be protective of the recreational designated
use. Mr. Ravenscroft noted that the TSM describes
a risk-based, multi-step approach for documenting

local conditions, estimating the potential for human
illness from recreational exposures in a waterbody
using quantitative microbial risk assessment (QMRA),
and comparing risk estimates to the RWQC. For
additional information, please refer to the EPA's
Technical Support Materials: Developing Alternative
Recreational Criteria for Waters Contaminated by
Predominantly Non-Human Fecal Sources.

Superfund Radiation Risk Assessment Approach to Assess
Human Consumption of Homegrown Food and Game
and Efforts to Assess Tribal Consumption of Plants and
Animals to Improve Assessments (presented by Stuart
Walker, OSRTI/EPA). Mr. Walker provided an overview
of the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA)
Superfund tools for conducting risk assessment at
radioactively contaminated sites, the Preliminary
Remediation Goals for Radionuclides (PRC) calcula-
tor and the Dose Compliance Concentrations (DCC)
calculator, and how they are used to protect humans
consuming home grown food (produce and ani-
mals) and humans consuming recreational game. He
noted that the EPA Superfund program has become
more involved in remediating uranium mines at
sites on Tribal lands and concerns have been raised
that existing Superfund calculators do not capture
all Tribal food exposures. Mr. Walker indicated that
this concern has been echoed at the classes that the
EPA has conducted on radiation risk assessment and
from panels on "Indigenous Perspectives on Risk
Assessment" at the Waste Management Symposium.
He described two EPA intern projects that identified
numerous Tribal exposure pathways that are not
already included in the PRC calculator, consisting of
73 additional produce categories, 64 additional animal
product categories, and one ceremonial category. Mr.
Walker mentioned that the EPA is currently evalu-
ating these additional produce and animal product
categories and that he anticipates that these categories
could be included in "site-specific mode" in the PRC/
DCC calculator. He noted that there are future plans
to evaluate the inhalation of smoke from ceremonial
plants and application of paints and dyes to the skin.

Derivation of Water Quality Values for Perfluorohexane
Sulfonate (PFHxS) and Perfluorononanoic Acid (PFNA)
(presented by Kevin D. Cox, Michigan Department of
Environment, Great Lakes, and Energy). Mr. Cox men-
tioned that Michigan's "Rule 57" Water Quality Values
(WQVs) for protecting humans, wildlife, and aquatic
life are calculated using a narrative procedure. Mr.
Cox mentioned that WQVs are applicable to the Great
Lakes, the connecting waters, and all other surface
waters of the state (unless site-specific values have
been derived). He noted that the human non-cancer
WQVs developed for PFHxS were 59 ng/L (drinking
water) and 210 ng/L (non-drinking water) and that the
human non-cancer WQVs developed for PFNA were
19 ng/L (drinking water) and 30 ng/L (non-drinking
water). Mr. Cox mentioned that these WQVs used
the same key studies and critical effects that had been
used to develop Michigan's drinking water maxi-
mum contaminant levels in 2019. He noted that the
bioaccumulation factor values used in calculating the
WQVs were developed using data from Michigan's Fish
Contaminant Monitoring Program and surface water
monitoring efforts. Mr. Cox mentioned that limited
aquatic toxicity data resulted in development of aquatic
life screening values for both PFNA and PFHxS.

Human Health Risk Assessment for 1,4-Dioxane in Drinking
Water Summary (presented by Frannie Nilsen, North Carolina
Department of Environmental Quality). Dr. Nilsen men-
tioned that the 1,4-dioxane monitoring results from
the EPA's Unregulated Contaminant Monitoring
Rule 3 (UCMR 3) led states with high rankings to
reevaluate 1,4-dioxane industrial sources, rules
related to water quality standards, and discharge
limits in affected permits. She noted that the North
Carolina Department of Environmental Quality
began monitoring across the state and that many
sites began monitoring independently. Analysis of

these monitoring results indicates that most North
Carolinians outside of the Cape Fear River Basin are
not exposed to 1,4-dioxane at concentrations above
the UCMR 3 national average but that some within
the Cape Fear River Basin are exposed to the third
highest drinking water concentrations in the nation.
Dr. Nilsen mentioned that the cancer slope factor of
0.1 mg/kg-day provided in the EPA IRIS assessment
was derived using the most health protective modeling
approach and will provide science-based protection
to North Carolinians from exposure to 1,4-dioxane
in their drinking water. She noted that a risk charac-
terization using the exposure data and health-based
values for the cancer endpoint is described in the
1,4-Dioxane in Drinking Water Legislative Report,
and the results indicate that North Carolina's residents
are exposed to 1,4-dioxane concentrations that maybe
two times the national average in drinking water and
as much as four times national averages in surface and
groundwater. Dr. Nilsen mentioned that regulatory
attention focused on reducing concentrations has led
to decreased 1,4-dioxane environmental and drinking
water exposure in the Cape Fear River Basin and that
public outreach efforts regarding 1,4-dioxane expo-
sure in drinking water resulted in many locations in
North Carolina decreasing 1,4-dioxane exposure out-
side of the Cape Fear River Basin.

Per- and Polyfluoroalkyl Substances (PFAS) in Final Treated
Solids (Biosolids) from 190 Michigan Wastewater Treatment
Plants (presented by Matt Reeves, Western Michigan
University). Dr. Reeves noted that the purpose of this
study was to characterize the concentration, distri-
bution, and variability of PFAS in final treated solids
(biosolids) using the results from the analysis of 350
samples collected for the Michigan Department of
Environment, Great Lakes, and Energy's Biosolids
Studies. He mentioned that the biosolids samples
were collected from a geographically diverse range
of wastewater treatment plants (WWTPs) serving
communities of various sizes and industrial activity.
Dr. Reeves noted that the study approach consisted of
analyzing PFAS signatures of freshly generated sam-
ples of biosolids at the end of the wastewater treatment
process. He described the conclusions for this study,
including that perfluorooctane sulfonate (PFOS)
was the most frequently detected PFAS in biosolids

in 2018-2022 (95% detection) throughout Michigan
despite the voluntary manufacturing phase-out in the
early 2000s; state-wide variability in biosolids PFAS
concentrations was primarily controlled by carboxyl
compounds of chain lengths C8-C12, and second-
arily controlled by short-chain carboxyls and PFOS;
usage of perfluorosulfonic acid (PFSA) replacement
compounds contributed to broad variance in biosolids
concentrations within Michigan WWTPs; and trends
in PFAS enrichment in biosolids for individual PFAS

vary at least three orders-of-magnitude, and generally
increase with compound hydrophobicity.

EPA Releases Final PFAS Aquatic Life Criteria
and Benchmarks

The EPA completed another commitment in its PFAS
Strategic Roadmap, finalizing science-based water
quality criteria and benchmarks for 10 PFAS that will
help states and Tribes protect fish and other aquatic
life from these chemicals. These water quality crite-
ria and benchmarks are not regulatory, nor do they
automatically become part of a state's water quality
standards. States and Tribes can consider using them
to develop water quality standards which inform the
implementation of other Clean Water Act programs,
like wastewater discharge permits.

The EPA's final perfluorooctanoic acid (PFOA) and
perfluorooctane sulfonate (PFOS) freshwater aquat-
ic-life criteria recommendations, published under
Clean Water Act Section 304(a)(1), are based on the
latest scientific knowledge about protecting freshwater
fish and other organisms from the effects of short-
term and long-term exposure to PFOA or PFOS. The
best available science indicates that PFOA and PFOS
levels in the environment appear to be significantly
below levels that would affect aquatic life, except in
areas where there is known contamination such as
Superfund sites.

The agency derived benchmarks to protect aquatic
life from short-term exposures to eight individual
PFAS in freshwaters (perfluorobutanoic acid [PFBA],

perfluorohexanoic acid [PFHxA], perfluoronona-
noic acid [PFNA], perfluorodecanoic acid [PFDA],
perfluorobutanesulfonic acid [PFBS], perfluorohex-
anesulfonic acid [PFHxS], hexadecafluoro-2-decenoic
acid [8:2 FTUCA], and pentadecafluorodecanoic acid
[7:3 FTCA]). The agency also developed aquatic life
benchmarks for short-term exposure to PFOA and
PFOS in saltwater environments. Like criteria, aquatic
life benchmarks are the highest science-based con-
centrations that would allow fish and other aquatic
species to live, grow, and reproduce. However, the
EPA develops these informational numeric bench-
marks under Clean Water Act Section 304(a)(2) when
there are limited high quality toxicity data available
and data gaps exist for several families of aquatic
organisms.

View the EPA's final PFAS aquatic life criteria and
benchmarks.

Acute 6PPD-q and 6PPD Aquatic Life Screening
Values for Freshwater

The EPA's Office of Water (OW) devel-
oped acute aquatic life screening values
for two widely distributed rubber-tire
associated compounds, N-(1,3-Dimethylbutyl)-
N'-phenyl-p-phenylenediamine-quinone
(6PPD-q) and N-(l,3-Dimethylbutyl)-N'-phenyl-
p-phenylenediamine (6PPD). The screening values
are based on the latest scientific knowledge about
the short-term (acute) toxicity of 6PPD-q and 6PPD
to aquatic organisms, including sensitive species

like coho salmon, in freshwaters of the United
States. While data limitations do not allow the
EPA to derive recommended 6PPD-q and 6PPD
water quality criteria for fresh or estuarine and
marine waters that follow the EPA's Guidelines

methods at this time, the agency has derived
screening values using the best available toxicity
data. For additional information, refer to the fol-

EPA's Unregulated Contaminant Monitoring Rule
(UCMR): Sixth Quarterly Release of Nationwide
Data on 29 PFAS and Lithium, Future Rule
Development, and Data Finders

•	On October 28th, the EPA published the sixth set
of drinking water data collected at public water
systems (PWSs) for 29 PFAS and lithium under
the fifth UCMR (UCMR 5). Over 1.1 million
analytical results are available for 7,237 PWSs to
date, representing approximately 55% of the total
results expected. The UCMR 5 data will ensure
science-based decision-making and help the EPA
better understand national-level exposure to the
29 PFAS and lithium, where and to what extent
PFAS co-occur with each other, and if commu-
nities are disproportionately impacted by these
contaminants in drinking water. The agency
will continue to publish results quarterly via the
UCMR 5 Data Finder, UCMR 5 Data Summary,
and data text files until completion of data report-
ing in 2026. The UCMR 5 resources and website
with answers to common questions also reflect
that six of the 29 PFAS for which monitoring data
are being collected are part of the EPA's April
2024 final National Primary Drinking Water
Regulation (NPDWR). PWSs will be required

to comply with the PFAS NPDWR Maximum
Contaminant Levels starting in April 2029.

•	Development for the next UCMR cycle (UCMR
6) is underway, with an anticipated proposed rule
publication by late 2025, final rule publication by
late 2026, and monitoring timeframe from 2027 to
2031. In early 2024, the EPA published a Federal
Register notice regarding the status of drinking
water analytical methods and hosted a related
webinar to discuss potential UCMR 6 monitoring

approaches, contaminants being considered, and
laboratory approval.

• Data from past UCMR monitoring cycles (UCMR
1-4) can be easily searched for and downloaded
using the EPA's UCMR Archival Data Finder or
accessed via standardized data text files.

Six-Year Review 4 of Drinking Water Standards

In July 2024, the EPA announced the results of the
fourth cycle of its Six-Year Review of existing national
primary drinking water regulations (NPDWRs).

Based on the agency's review of existing NPDWRs,
the EPA determined that there are no additional can-
didates identified for regulatory revision. The Safe
Drinking Water Act (SDWA) requires the EPA to
conduct a review every six years of existing NPDWRs
and determine which, if any, are appropriate for revi-
sion. The purpose of the review is to evaluate available
information for regulated contaminants to determine
if any new information on health effects, treatment
technologies, analytical methods, occurrence, expo-
sure, implementation, and/or other factors provides
a basis to support a regulatory revision that would
improve or strengthen public health protection.

The EPA did not include in this Six-Year Review cycle
the recently promulgated per-and polyfluoroalkyl
substances (PFAS) regulations. The PFAS regula-
tions, promulgated in April 2024, established six new
NPDWRs. The EPA anticipates that once the PFAS
regulations go into effect and sufficient information
regarding compliance monitoring becomes available,
those NPDWRs will be subject to a more detailed reg-
ulatory review under a future Six-Year Review cycle.

The EPA's Office of Water (OW) is sharing its existing
SOP and DERs for systematic review of ecological
toxicity data for aquatic life and aquatic-dependent
wildlife. The SOP and DERs provide information on
the systematic review and documentation process
OW uses with ecological effect studies when devel-
oping Ambient Water Quality Criteria and other
values for the protection of aquatic life and aquat-
ic-dependent wildlife. The SOP is generally consistent
with procedures developed by the EPA's Office of

MDH's PFAS and Infant Formula Study

The Minnesota Department of Health conducted a
small study investigating potential PFAS contami-
nation in powdered infant formula. MDH scientists
tested 17 formulas for various PFAS and found a
detectable level of PFOS in one formula. An exposure
analysis indicates the single PFOS detection in pow-
dered infant formula is not a major source of PFOS
relative to other sources, and a subsequent risk assess-
ment comparing various formula-fed infant scenarios
to the Minnesota Department of Health's 2024 PFOS
reference serum concentration (2.6 ng/mL) concludes
that PFAS from powdered formula likely does not pose
a significant risk to infants. The publication is open
