Performed project for Alcoa evaluating ecological risks associated with air emissions of sulfur dioxide, hydrogen fluoride, PAHs, and particulate material from a proposed aluminum smelter in Reyðarfjörður, Fjarðabyggð, Iceland. The primary objective of this predictive risk assessment was to determine whether there would be consequential differences in the level of risk posed by air emissions from the smelter operation with and without seawater scrubbers. The ecological risk assessment incorporated spatially and temporally explicit exposure modeling in a probabilistic framework to evaluate risks to plants, birds, and mammals. The risk assessments concluded that the smelter would not pose consequential risk to ecological receptors under either scenario; however, exposure to all constituents would be considerably higher for a smelter with seawater scrubbers.
Conducted a baseline ecological risk assessment for Operable Unit 3 of the Horseshoe Road and Atlantic Resources Corporation Superfund sites in Sayreville, New Jersey. Assessment evaluated risk to invertebrates, fish, and wildlife in the marsh and intertidal portions of the Raritan River that are adjacent to the sites from exposure to PCBs, metals, PAHs, and pesticides.
Conducted an ecological scoping assessment of chemicals from historical mining operations at a site in Grass Valley, California. The chemicals of potential concern were arsenic, lead and mercury in soils. The scoping assessment identified habitats on the site that support plants and wildlife and delineated potentially complete exposure pathways of the chemicals of concern to receptors in these habitats.
Performed a screening-level ecological risk assessment for The City of Sitka, Alaska for a former municipal solid waste incinerator. Operation of the facility and past waste handling practices had been linked to the detection of metals and PCDD/Fs at concentrations greater than the Alaska Department of Environmental Conservation (DEC) residential cleanup levels within onsite and offsite soils and an adjacent wetland area. The assessment evaluated whether adverse impacts to the environment could occur now or under reasonably likely future use, as a result of direct or indirect exposure to site-related chemicals.
Evaluated sediment contamination and ecological risks of metals (e.g., copper, zinc, and butyltins) and organic substances (PAHs and PCBs) at two major shipyards in San Diego Bay. Site-specific studies included sediment triad assessment and sampling of resident biota for bioaccumulation and histopathology analyses.
Managed and conducted an ecological risk assessment on behalf of Beazer East, Inc. for a former Koppers Company wood treatment facility located near Newport, Delaware. The work involved assessing effects of PAHs and metals on wetland and terrestrial flora and fauna, developing site-specific ecotoxicity thresholds for sediment and soil, and evaluating residual risk associated with different remedial alternatives. Also managed an evaluation of issues relevant to potential natural resource damage claims for the site and an identification of potential restoration alternatives.
