Developed a scope of work and sampling and analysis plan to support a site-specific human health and ecological risk assessment of contaminants associated with historic fuel oil release in upland, wetland, and aquatic habitats.

Conducted an ecological risk assessment and provided technical support to the feasibility study of former army base, which included four upland areas of concern and one containing marine sediments. Characterized risk to aquatic organisms, fish, and wildlife through a combination of empirical investigation and modeling. Developed cleanup numbers in sediment and soil for polychlorinated biphenyls (PCBs), DDT, dieldrin, and lead that would be protective of ecological receptors at the former army base.

Managed an ecological risk characterization for a boat yard in southeastern Massachusetts. The assessment evaluated exposures of ecological receptors to metals, PCBs and tributyltin (TBT) in sediment and the food chain. The work included collection of representative aquatic organisms, sediment toxicity tests, exposure pathway analysis, selection of contaminants of concern, fate and transport analysis, and the identification of toxicological endpoints, and combining these elements in a risk characterization.

Managed a human health and ecological risk assessment for a property along the Mystic River near Boston, Massachusetts. The assessment evaluated exposures of ecological receptors to arsenic, lead, polynuclear aromatic hydrocarbons (PAHs), extractable petroleum hydrocarbons (EPH) and PCBs in groundwater, soil and sediment. Considered future uses of property in human health risk assessment.

Conducted an ecological risk assessment for a Brownfields site, which abuts the Chelsea River in Chelsea, Massachusetts. The property was a lithographic facility that produced wrappers and labels and is being redeveloped for residential and retail use. Conducted an exposure pathway analysis, selection of contaminants of concern, fate and transport analysis, and the identification of toxicological endpoints and a risk characterization.

Conducted an ecological risk assessment for a large, eutrophic water body with metal contaminated sediments in Massachusetts. Characterized risks to benthic invertebrates, planktonic invertebrates, fish and wildlife using site-specific information on the water body and three reference areas. Site-specific data included body burdens of metals in fish, submerged aquatic vegetation, and freshwater clams; sediment and water column bioassays; benthic and planktonic invertebrate community assessments over two season; synoptic survey of fish communities; field observations of wildlife; and food chain modeling to wildlife.

Conducted an ecological risk assessment for a site containing wetlands in Gloucester, Massachusetts. Evaluated the potential risk from metals and PAHs in the sediment and wetland soil to the environment based on a comparison to background levels and evaluations for aquatic life and wildlife based on site-specific information (e.g., toxicity test bioassays, bioaccumulation tests, and food chain modeling). Developed cleanup numbers in sediment and soil for chromium that would be protective of ecological receptors at the site.

Managed a human health and ecological risk assessment for a former incinerator facility in northeast Massachusetts. Dioxins, furans, PAHs and certain metals were found in soils and sediments above background levels. Potential risks from these chemicals to a recreational fisher, trespasser, utility work, construction work and parking lot landscaper were evaluated. The environmental characterization, which was conducted for a nearby pond, evaluated risk to aquatic organisms and semi-aquatic wildlife based on body burdens of contaminants in fish and benthic invertebrates, and on estimated exposure to contaminated sediment and prey.

Collected and evaluated data on metal concentrations in fish tissues to estimate the potential for risk to human health and ecological receptors (e.g., fish and wildlife) that may use a large lake at a former army base in Alabama.

Conducted an extensive review of the available information on the toxicity of dioxin-like compounds to birds. Compiled a database of dose-response relationships that was used to develop a species sensitivity distribution for effects to avian species.

Co-authored a literature review of scientific studies on the ecological effects of engineered nanomaterials.

Reviewed literature on the effects of cyclodiene pesticides on fish and relationships between fish tissue residue levels and effects to support the development of tissue residue levels that are protective of fish.

Reviewed literature on the evaluation and consideration of the effects of non-chemical stressors in dredging projects for preparation of a manuscript with US Army Corps of Engineers on applying risk assessment approaches to non-chemical stressors related to dredging.

Conducted an environmental evaluation of a proposed water desalination plant adjacent to the Mediterranean Sea. Described the potential impacts of the desalination plant processes (e.g., wastewater discharge) on the surrounding marine environment based on a review of the ambient conditions. Described the potential impacts from the surrounding Mediterranean environment (e.g., nuisance algal blooms) to the proposed desalination plant. Provided recommendations for mitigating those potential impacts to the water desalination plant and the surrounding aquatic environment.
