                    science  BRIEF
EPA scientists develop science and tools to help communities identify and
prioritize environmental health issues
     Issue:
     Community groups want to understand their
     exposures and risks to environmental
     pollutants. They also want to know how to
     effectively reduce exposures to pollutants
     with the highest risks. If relevant science-
     based tools are not readily available,
     decisions may be based solely on the
     perception of exposures and risk.  EPA
     scientists are developing tools to improve
     community access to scientific information.

     Community involvement is crucial in
     defining and prioritizing environmental
     health issues for specific areas or groups of
     people.  Community groups and members
     can supply local knowledge and interpret
     results in the context of local decision-
     making. Because of this, communities are
     playing an increasingly central role in
     defining environmental problems and
     identifying the information needed to address
     these problems. Involvement of communities
     is equally important where evidence indicates
     disproportionate exposures or risks are
     caused by localized contaminants or other
     environmental conditions.

     To support communities with this process,
     user-friendly tools are needed that provide
     environmental exposure and health-related
     information.  To ensure these tools are
     scientifically sound, research is necessary to
     advance the science to take into account the
     many factors that may impact human
     exposure and health risks within a
     community — including chemical and non-
     chemical factors.
                                                   Science Objective:
                                                   EPA is developing the Community-Focused
                                                   Exposure and Risk Screening Tool
                                                   (C-FERST) — a GIS & resource access Web
                                                   tool to support cumulative human exposure
                                                   and risk screening assessments, and help
                                                   build sustainable, healthy communities. It is
                                                   designed to assist communities with the
                                                   challenge of identifying and prioritizing
                                                   issues, and making decisions about exposures
                                                   and risks within their community. C-FERST
                                                   supports EPA's priorities for cleaning up
                                                   communities and working for environmental
                                                   justice to protect vulnerable groups of people.

                                                   C-FERST provides a framework for
                                                   collaborative research and information
                                                   sharing to understand community-based
                                                   exposures and risks.  It will be used to assess
                                                   exposures to multiple chemical factors and,
                                                   eventually, will incorporate non-chemical
                                                   factors. Ultimately, it is anticipated that the
                                                   improved science and user-friendly tool will
                                                   empower environmental managers and
                                                   community residents to make decisions about
                                                   environmental issues specific to their location
                                                   that result in better-informed decisions.

                                                   Application and  Impact:
                                                   C-FERST will link to and build upon other
                                                   community-focused  tools to help identify
                                                   human exposures within a community and
                                                   help prioritize issues for taking action to
                                                   improve public health.

                                                   C-FERST has been developed in
                                                   collaboration with certain projects of the

-------
EPA-coordinated community program called
CARE (Community Action for a Renewed
Environment). The CARE grant and
technical assistance program
(www.epa.gov/care) offers an innovative way
for communities to reduce pollution in their
local environment.

During C-FERST's development, EPA
scientists will listen to community residents
and local officials to refine the tool. In 2011,
EPA scientists will work with several CARE
communities to test and refine the tool. C-
FERST ultimately will offer information for
the general public. Future users could include
community members and leaders, as well as
federal, state, or local agencies working with
community partners.

Eventually, C-FERST users will be able to
view maps and community reports  for
environmental issues such as  air toxics, diesel
exhaust, lead, environmental tobacco smoke,
water pollution, fish consumption, residential
pesticides. Users will also be  able to view
cumulative risk estimates for  lung cancer,
asthma, and early neurotoxicity effects. As
the tool is refined and populated with
available information, users will be able to:

Consider/identify  environmental issues by:
   •   Viewing guidance, and learning about
       issues other communities have
       considered
   •   Accessing information about
       environmental, health, social and
       economic issues
   •   Accessing methods for local
       monitoring

Access fact sheets  for environmental issues
of concern including:
   •   EPA and other federal fact sheets for
       over 40 community environmental
       issues

Visualize exposure/risk via mapping tools
that allow users to:
   •   Map environmental concentrations,
       human exposures, and health risks
   •   Overlay pollutant sources
    •   Overlay demographic data for
       identifying vulnerable populations
    •   Add local data
    •   View potential impact of solutions

Generate environmental issue profiles with
the help of:
    •   Fact sheets, web-links, local exposure
       estimates, maps, and community
       solutions available in a consistent
       report format for each selected issue

Prioritize your community's issues by:
    •   Viewing community data table
    •   Accessing examples of risk ranking
       approaches

Explore potential solutions including:
    •   Links to fact sheets on exposure/risk
       reduction actions
    •   Information on promising practices
       for sustainable community solutions

Link to other community-relevant tools
including:
    •   A searchable compendium of
       community-relevant tools, and Web
       links to other tools.
