INNOVATIVE RESEARCH FOR A SUSTAINABLE FUTURE
  Advanced Materials and Solids Analysis Research Core (AMSARC)
  Providing EPA researchers and collaborators with the latest technology
  What is AMSARC?
  The Advanced Materials and Solids
  Analysis Research Core (AMSARC),
  centered at the U.S. Environmental
  Protection Agency's (EPA) Andrew
  W. Breidenbach Environmental
  Research Center in Cincinnati, Ohio,
  is the foundation for the Agency's
  solids and surfaces analysis
  capabilities. The state-of-the-art
  analytical equipment that
  comprises AMSARC will benefit
  researchers in all of EPA's
  laboratories in Cincinnati, as well as
  other EPA research centers across
  the nation. It is expected that
  AMSARC will establish a stimulating
  and collegial environment for
  conducting cutting edge research
  that will benefit continued progress
  toward global sustainability,
  materials management, pollution
  prevention, and public health.

  Mission
  Cutting-edge research tools offer
  great flexibility and breadth to
  EPA's research. AMSARC
  technology supports various EPA
  projects, including water quality
  research,  corrosion control, green
  chemistry, bacteria and
  nanomaterials characterization,
  arsenic removal from drinking
  water, and many others. The
  mission of AMSARC is to support
  EPA's materials science and
            engineering-related research
            activities while fostering
            multidisciplinary research
            collaborations. AMSARC will assist
            EPA's scientists and engineers to
            develop innovative solids analysis
            and preparation techniques and
            maintain proficiency with state-of-
            the-art practice techniques.

            Collaboration and Use
            Because AMSARC is not a
            standalone entity, staff will not be
            specifically associated with it.
            AMSARC users include principle
            investigators and analysts that use
            or rely on the instruments to
            complete their research.
            Specifically, EPA research staff in
            Cincinnati, including engineers,
            chemists, and technicians, make-up
            the workforce tied to activities
            within AMSARC. Contract staff,
            students, and postdoctoral
            researchers also constitute
            AMSARC users.
            Beyond research on specific
            projects, some staff members also
            have the responsibility of being a
            contact person for one or more
            AMSARC instruments. That is, they
            have been identified as an expert
            on a specific instrument. As an
            expert, they may also  provide
            training to other users, approve
            skills of potential instrument users
            before they independently use the
instrument, and offer technical
assistance to others.
In all aspects of our work, from
problem identification and research
design, and through to
implementation, we must involve
the widest span of disciplines to
bring different perspectives to the
table.  Research planning involves
extensive outreach to stakeholders
to obtain input, and collaboration
with EPA's program offices, which
establish standards to protect
public  health and the environment,
and the Agency's regional offices,
which  support and enforce the
implementation of regulations.
