I    In 1985, Drs. Joseph Cotruvo, Edward Ohanian, and Penny Fenner-Crisp of the U.S. Environmental
    Protection Agency's (EPA's) Office of Science and Technology, Health and Ecological Criteria Division,
  started FSTRAC to build a better relationship with states and tribes to exchange research priorities and
  results, policy concerns regarding water-related human health risk assessment, and technical information.
  FSTRAC is made up of representatives from state and tribal health and environmental agencies and EPA
  Headquarters and Regional personnel. As described on the EPA FSTRAC Web page (http://www2.epa.gov/
  water-research/basic-information-fstrac), FSTRAC is an integral part of EPA's communication strategy with
  states and tribes. FSTRAC fosters cooperation,  consistency, and an understanding of EPA's and different
  states' and tribe's goals and problems in human health risk assessment. It allows states, tribes and the federal
  government to work together on issues related to the development and implementation of regulations and
  criteria under the Safe Drinking Water Act and Clean Water Act.
Recent Webinars

FSTRAC holds several webinars each year to share
information through presentations and discussions
regarding human health risk analysis and the water
medium of exposure.

September 2015 FSTRAC Webinar
EPA held a FSTRAC Webinar in September 2015
during which the following topics were discussed:

findings. Dr. Donohue also presented the major peer
review comments.

Pharmaceutical Water Screening Values (presented by
Ms. Ashley Suchomel, Minnesota Department of Health):
Ms. Suchomel presented information on a rapid
assessment method required by the Minnesota
Department of Health that could be performed effi-
ciently and with limited information sources to assess
and prioritize a large number of pharmaceuticals,
including commonly prescribed pharmaceuticals not
currently included in water monitoring programs.
She provided information on the pharmaceuticals
assessed, the methods for assessing pharmaceuticals,
results of the assessments, and how to use the derived
water screening values.

EPA Drinking Water Health Advisories for Cyanotoxins (pre-
sented by Dr. Lesley D'Anglada, OW/EPA): Dr. D'Anglada
provided a detailed summary of EPA Health
Advisories for microcystins and cylindrospermop-
sin. These health advisories were published in June,
2015. Along with the health advisories, EPA also
published a cyanotoxin management document as
a companion to the HAs. The document is designed
to provide information and a framework that Public
Water Systems and others can consider to inform their
decisions on managing the risks from cyanotoxins to
drinking water. Additional information is provided
on EPA's CyanoHABs website (http://www.epa.gov/

A Cross-Sectional Study on Low-Level Exposure to Manganese
from Drinking Water and Children's Neurobehavioral
Function (presented by Dr. Maryse Bouchard, Universite de
Montreal): Dr. Bouchard provided background infor-
mation on manganese exposure and neurotoxicity in
occupational settings, mechanisms of toxicity, and
manganese in water and food, as well as information
on the vulnerability of children to manganese and the
neurotoxic effects of manganese in children. She pre-
sented detailed information on the New Brunswick,
Canada, study on low-level exposure to manganese in
drinking water in New Brunswick and children's neu-
robehavioral function, including preliminary results.

Environmental Surveillance and Monitoring - The Next
Frontier for Pathway-Based High Throughput Technology
(presented by Dr. Daniel L. Villeneuve): Dr. Villeneuve
noted that sources of pathway-based bioeffects data
are growing rapidly and that Adverse Outcome
Pathways (AOPs) offer a formal framework for linking
pathway-based bioeffects to hazards of concern for
ecological and/or human health risk assessment. He
noted that AOPs, along with complementary exposure
tools being developed by EPA's Chemical Safety for
Sustainability (CSS) research program, offer potential
new data streams to support water quality guideline
and criteria development.
Incorporation of DU-MIS ("ISM") Investigation Methods in
Environmental Risk Assessments (presented by Dr. Roger
Brewer, Hawai'i Department of Health): Dr. Brewer pre-
sented information on the limitations in the use of
discrete soil sample data, including determining
the extent of contamination, making comparisons
to screening levels, and estimating exposure area
mean. He also provided information on the basics of
"Decision Unit (DU)" and "Multi Increment Sample
(MIS)" (also known as "Incremental Sampling
Methodology or "ISM").

Risk Assessment Issues

Drinking Water
Maine Center for Disease Control & Prevention
More than half of Maine residents rely on a private
well for their drinking water, and about 10% of those
wells have too much arsenic. Therefore it is important
to understand what residents can do to reduce their
exposure to arsenic. Maine CDC receives about 1,000
phone calls each year from residents with questions
about their well water. What many callers want to
know is what they can do to keep their families safe,
and specifically, if it is safe to take a bath in water
high in arsenic. With this context, the Maine CDC
joined with colleagues from the U.S. CDC to assess
remaining arsenic exposure sources among families
that have arsenic in their well water and that have
switched to bottled water or installed an arsenic
treatment system at the kitchen sink. The results of
this study "Assessing arsenic exposure in households
using bottled water or point-of-use treatment systems
to mitigate well water contamination" were published
in Science of the Total Environment this February

In February, HECD released the technical support
document, A Practitioner's Guide to the Biological
Condition Gradient: A Framework to Describe
Incremental Change in Aquatic Ecosystems. This doc-
ument outlines a scientific framework, the biological
condition gradient (BCG), which states, territories,
and tribes can use to interpret biological responses to
increasing effects of stressors on aquatic ecosystems.
The BCG framework can be populated with state or
regional data to develop a quantitative model using
expert judgment that describes ecosystem changes

Drinking Water Contaminant Occurrence
Unregulated Contaminant Monitoring Rule
EPA uses the Unregulated Contaminant Monitoring
Rule (UCMR) program to collect data for contami-
nants suspected to be present in drinking water, but
that do not have health-based standards set under the
Safe Drinking Water Act (SDWA). Every five years EPA
                                                   develops a new list of UCMR contaminants, largely
                                                   based on the Contaminant Candidate List (CCL).

                                                   The third Unregulated Contaminant Monitoring Rule
                                                   (UCMR 3) was published in the Federal Register on
                                                   May 2, 2012. UCMR 3 requires monitoring for 30
                                                   contaminants: 28 chemicals and 2 viruses. The latest
                                                   UCMR 3 data summary, reflecting results reported
                                                   through December 2015, was posted to http://www.
                                                   epa.gov/dwucmr. Updates occur approximately quar-
                                                   terly and EPA anticipates that additional reference
                                                   material will be made available to assist with the
                                                   assessment of the UCMR 3 data. Please keep in mind
                                                   that this dataset is not complete. UCMR 3 monitor-
                                                   ing occurred through December 2015, and data are
                                                   expected to be reported to EPA through the summer
                                                   of 2016. These results are subject to change following

                                                   Rule (UCMR 4) was proposed on December 11,
                                                   2015. The proposal outlines monitoring for 30 chem-
                                                   ical contaminants between 2018 and 2020 using
