International Activities: Dr Troast was senior scientist and regulatory affairs specialist on USAID contract No.
GS-10F-0112K ( Jordan Industrial Manifest Program) assisting leaders of the Ministry of the Environment and
other Ministries within the Kingdom of Jordan to understand the movement of hazardous waste within the
Kingdom, researching methods for the destruction of hazardous waste, designing a reportable quantities system for
tracking hazardous waste, and designing analytical laboratory practices including designing a GLP manual for the
Royal Scientific Society (RSS) of Jordan to use to provide oversight for the Ministry of the Environment
(MOEnv). Dr Troast was the representative for the project and reported directly to the Ministerial working group
and to the leadership of the RSS when critical junctures were reached. Dr Troast provided outreach assistance as
needed and provided working models of critical agreements to facilitate the design of information between
Ministries who were being charged with the control of hazardous waste within the Kingdom.
Dr Troast was a lecturer for Forum Training and Consulting in Greece, an internationally recognized organization
providing seminars to industrial leaders and senior technical staff . Dr Troast’s lecture areas included risk control
and risk management concepts for hazardous waste practices, regulatory philosophies for toxic and hazardous
materials, and technical concerns for lead and metals and asbestos.
Domestic Activities: Dr Troast while working at the USEPA was a senior scientist for the Remedial cleanup or
Superfund program. He was the Chair of several review committees dealing with enhanced procedures for
measuring and reporting lead and metals exposure and determining risks from these exposures. Dr Troast also
re-structured the remedial program’s emphasis on asbestos remediation and organized and chaired several national
meetings which brought together federal and State agencies to discuss asbestos toxicity and exposure
characteristics especially as they related to the fiber types. He directed the model improvements was a major
proponent of the use of the Risk assessment tool for lead, the Integrated Exposure Uptake and Biokinetic Model,
which was the only accepted risk assessment model used by EPA. This model is still a major tool for estimating
children’s blood lead. He was a co-contributor to the EPA’s Adult Lead Model which is the corresponding model
used for estimating body burden for adults. Dr Troast, in conjunction with Jobe Consulting Group, has taken
leadership roles on assessing chemical use and hazards in the National Forests for the US Forest Service. Dr Troast
has assisted several law firms with interests in lead and lead paint toxicity and asbestos exposure.
Adjunct Professor in Biology and Environmental Science
January 2005 – Dec 2012
Dr Troast has lectured at Lord Fairfax CC, Warrenton, VA and Germanna Community College, Fredericksburg
VA. He teaches Environmental Science, Anatomy and Physiology, and Biology.
Guest Lecturer for Genomics and Bioinformatics
George Mason University, Manassas, VA
College of Sciences, Department of Biotechnology and Informatics
January 2004 – May 2007
Sr. Environmental Scientist,
1990-2005(retirement)
US EPA, Office of Emergency and Remedial Response (OERR)
Chair of the Superfund Asbestos Task Force, Chair of Metals Technical Review Workgroup, Member of
EPA Genomic Taskforce, Member EPA Regulatory Workgroup
Dr Troast was responsible for the interagency coordination for and oversight of Superfund and hazardous waste
activities that crossed over to other program responsibilities, such as those to control industrial waste water and
provide clean drinking water. As a member of the Genomic Workgroup, Dr Troast developed regulatory guidance
for interpreting genomic based toxicological data and had these data published and adopted by EPA. During Dr
Troast’s tenure as Chair of the Metals Workgroup, he managed the development of a new computer model used
extensively by EPA and other Federal programs to predict risks from lead to children and adults from
environmental releases into waste streams and drinking water. Dr Troast began the review of in vitro methods for
establishing exposure parameters for metals. This review was completed post-retirement and published outside of
EPA. While he chaired the Asbestos Task Force, the group developed new methods for asbestos sampling, and for
identifying asbestos fibers in the environment, and developed a new exposure/risk paradigm to account for
differing toxicity values among the various forms of asbestos, and developed a revised risk assessment method
used for amphibole asbestos. Dr Troast also chaired numerous national conferences and public meetings for both
the Metals and Asbestos programs and these meetings were well received by the scientific community, concerned
citizens and local governments.
Member of the ILSI Health and Environmental Sciences Institute (HESI) work group 2001-2005
As a member of this workgroup which was comprised of comprised of leading industry and Federal scientists
the charge was to develop a basis for a mutual understanding of applying genomic data to toxicology. A major
concern was to harmonize data assessment among the Federal programs that use the information for health and
safety reviews.
Office of Pesticides and Toxic Substances, Chemical Testing Branch (TSCA) 1980-1989
As branch and section leader Dr Troast had oversight for the analysis of chemical and toxicological data supplied
by industry using the authorities of TSCA sections 4, 5 and 8 to determine whether further data was required to
fully understand and characterize the potential toxicity of chemicals that were potentially released via industrial
processes to near-by populations. A key function was the design of the testing requirements for chemicals whose
database was viewed as unacceptable under the standards of the Toxic Substances Control Act. Chemical testing
programs were tracked and managed according to the rule that was published requiring that affected industries to
develop the data. Studies were analyzed and recommendations made for further action if required.
Legislative Fellow
1987-1988
Dr Troast was selected by US Office of Personnel Management to serve as a LEGIS Fellow for the second session
of the 97th Congress. In this capacity Dr Troast served with Senator Gordon Humphrey (R-NH) as a legislative
aide focusing on environmental legislation pending before the US Senate. Significant actions included legislation
on Amending the Clean Air Act, The Clean Water Act, Toxic Air Pollutants, Asbestos in Schools, and Radon.
Office of Pesticide Programs (FIFRA) US EPA
1973-1980
Responsibilities included reviewing scientific supporting data for pesticide applications, and establishing criteria
for removing or limiting pesticide usage based upon toxicological data.
