Barr's Mercury Specialists
The Barr staff members who specialize in mercury issues
make our company one of the preeminent providers of mercury
testing, investigation, impact assessment, and minimization
in the upper Midwest. The following individuals offer our
clients unusual depth and breadth of expertise in the mercury
arena:
- Carol
Andrews,
P.E., an environmental engineer who prior to joining
Barr served as the project manager for the Minnesota Pollution
Control Agency's Mercury Contamination Reduction Initiative;
since joining Barr in 1999 she has co-authored a white paper
("Modeling
the Fate of Mercury in Products") and a report
("Mercury
Reductions via Public/Consumer Outreach"). In addition
to conducting mercury-mass-balance analyses, Carol has worked
on a number of projects aimed at identifying sources of
mercury— (including sources that release mercury to
wastewater) and implementing programs to reduce mercury
releases.
- Harry
Debye, Ph.D., an internationally known toxicologist
with extensive experience in toxicology, epidemiology, multipathway
human-health and ecological risk assessment. Harry has a
thorough understanding of the toxicokinetics, pharmacokinetic
mechanism, and chemical interaction of mercury. He has conducted
evaluations of the environmental fate and transport of mercury,
as well as probability analyses of the potential for and
magnitude of potential human-health and environmental risk
associated with mercury emissions from power-generating
facilities, mining operations, and oil refineries.
- Eric
Edwalds, an air quality scientist, and Paul Taylor,
Ph.D., a
senior chemical engineer, who perform air emission calculations
and conduct air dispersion modeling in support of screening-level
and multipathway risk assessments that require evaluation
of mercury releases, transport, and deposition.
- Paula
Jackson,
a technical writer who prepares educational materials for
business and public audiences on mercury sources and reduction
programs. Paula co-authored the white paper "Modeling
the Fate of Mercury in Products" with Carol Andrews.
- Teresa Perry,
P.E., an environmental
engineer who specializes in assisting clients with strategies
to reduce mercury in wastewater. Her experience includes
assisting the city of Hibbing, Minnesota, with obtaining
a variance for its low-level mercury NPDES limit; the resulting
permit was one of the first in
the state to contain a low-level mercury limit. Teri
is also are helping the city develop a mercury reduction
program, and is completing a mercury treatability study
to determine if additional mercury removal can be obtained
through the wastewater treatment process.
- Tim
Russell, a senior chemical engineer who heads Barr's
air testing group and
has conducted mercury emissions tests at a variety of industrial
facilities to determine mercury emissions. Tim has successfully
designed and executed tests as part of facility mercury-mass-balance
studies.
- Cliff
Twaroski, an air quality scientist with experience in
atmospheric deposition impacts assessment and ecological
risk assessment. Cliff's experience includes developing
a screening analysis for potential local (near-source) mercury
deposition, designing mercury mass-balance sampling, and
estimating mercury deposition. As a member of the Science
Advisory Committee for the University of North Dakota's
Energy and Environment Research Center, Cliff provides technical
review of research proposals related to mercury speciation
and transformation in air emissions, soil, and the water
column.
