Tamara D. Lunsman, Ph.D.

Senior Environmental Toxicologist

Email VCard Bio

Dr. Lunsman has over 10 years of experience in aquatic toxicology, water quality, and environmental fate and pathways.  Her expertise includes evaluating environmental risks of pharmaceuticals and other industrial chemicals and products, conducting environmental hazard assessments, green chemistry and sustainability, and regulatory ecotoxicity testing.  Her primary responsibilities include reviewing and interpreting ecotoxicity data and applying this information to evaluate site-specific or chemical-specific risks.  Dr. Lunsman has an interdisciplinary background in ecological site characterization and remediation, environmental impact analysis, wetland restoration, and regulatory compliance.  Dr. Lunsman has 7 years experience managing multidisciplinary natural resource projects for over 15 National Environmental Policy Act (NEPA) documents and natural resource assessments.

Representative Projects

Ecological Risk Assessment:  Provided ecological risk support and risk-based remedy negotiation activities at a site containing a swale impacted by historic PCB contamination.  Compiled information from a wetland survey and habitat function and value assessment to identify relevant ecological exposure pathways.  Conducted an ecological risk assessment, leveraged existing data, considered habitat quality, and estimated ecological risks following planned remediation efforts to comply with standards.

Hazard Categorization:  Compiled best available toxicological data on various ecological endpoints to contribute in the determination of hazard categorizations on chemicals.  Performed quality control and quality assurance for the ecotoxicology section of hazard assessments and classified according to the United Nations Globalized Harmonized System (GHS) guidelines.  In the absence of toxicological data, professional judgment was used to determine hazards.

Regulatory Workshop Development:  As part of US EPA's National Ambient Air Quality Standards (NAAQS) review for ozone, assisted with the formation of a presentation for an open panel forum/educational workshop covering three documents:  the Welfare Risk and Exposure Assessment (WREA), the Policy Assessment (PA), and the Proposed Rule (PR).

Regulatory Review:  As part of US EPA’s National Ambient Air Quality Standards (NAAQS) review for ozone, prepared regulatory comments on the proposed rule, the welfare risk and exposure assessment, and the policy assessment.

Environmental Impact Assessment:  Provided technical expertise and managed a team of experts to support several Environmental Impact Statements (EISs) for the Naval Facilities Engineering Command (NAVFAC).  Included the preparation of several Biological Evaluations (BEs) in compliance with Section 7 of the Endangered Species Act and Letters of Authorization (LOAs) pursuant to the Marine Mammal Protection Act (MMPA) to assess the potential impacts of naval exercises in sites located along the US east coast.

Pharmaceutical Environmental Risk Assessment: Evaluated the environmental risk associated with the societal use of an active pharmaceutical ingredient for a major pharmaceutical company,  compliant with European (EMA) and US (FDA) risk assessment guidelines. Oversaw the collection of additional environmental fate and toxicity test data.
