  • Full Profile

    Tom Biksey serves as a project manager and technical expert on multi-disciplinary environmental assignments throughout the world. These projects include both baseline information development and spatial and temporal analysis of existing and projected impacts on human and ecological receptors. As manager and senior technical lead on these projects, he interacts directly on the client’s behalf with U.S. Environmental Protection Agency and state regulatory agencies as well as various international, regional, and local departments and authorities. In addition, through his overseas assignments in Australia, United Kingdom, United Arab Emirates, Bahrain, Oman, Qatar, Spain, Portugal, Nigeria, Sweden, Yemen, and Venezuela, Tom has an appreciation of the cultural and technical challenges of international work.

    In his primary role, Tom provides technical input from work plan through remedial alternative selection and risk communication, and has designed and conducted ecological and human health risk assessments for site investigations and remedial response actions at regulated and non-regulated facilities. The significance of the potential risks characterized is the key cost-benefit factor for determining the level of effort required for any additional risk assessment phases versus overall site cleanup costs. To meet client expectations, he focuses the risk assessments in a cost-effective manner that demonstrates responsibility for assessment of impacts and ensures environmentally sound protective strategies. His overall approach provides the risk manager with the information necessary to eliminate unwarranted remediation activity through the identification of aggressive remediation goals for realistic risk-reduction. Tom also conducts risk analysis in support of insurance liability and coverage, and REACH compliance.

    Tom’s primary responsibilities include human health and ecological risk assessments, sediment and water quality issues, and natural resources assessments. In addition, he provides expert testimony and legal support on projects including recovery of cleanup costs and safe remediation of sites. As a client advocate, he reviews and develops comments on proposed regulations and guidance documents, and provides overall technical guidance to project teams developing risk-based solutions to environmental management issues. He has developed position papers, participated on technical guidance development committees, chaired and presented technical sessions at conferences, peer-reviewed technical manuscripts, and conducted technology transfer workshops and seminars. He has published extensively in the scientific literature, and he is an adjunct professor and undergraduate research advisor.

    Tom also provides technical and negotiating support to clients pursuant to regulatory permitting, due diligence, fate and transport modeling, natural resource assessments, NEPA activities, and licensing requirements. Actions included revising carcinogenic criteria, FIFRA preemption, determining metal bioavailability, forensic investigations, conducting thermal variance studies, and investigating fish kills. He participated in studies for permitting applications that included QSAR analysis, hydrodynamic and sedimentation modeling, jurisdictional wetlands, oil field decommissioning, and wetland treatment systems. To aid the client in managing and analyzing complex data sets, he has designed and developed data base management systems for application with GIS programs.

    Key Projects

    Ecological risk assessor for Fish and Wildlife Impact Analysis (FWIA) pursuant to an Order on Consent with the New York State Department of Environmental Conservation (NYSDEC) for an operable unit. The FWIA describes the ecology of the site and the surrounding environment including fish and wildlife resources and associated flora and fauna for the ecological communities within the study area, and evaluates the exposure to, and ecological effects of identified constituents of concern on the identified ecological receptors. The objective of the FWIA, currently in the Step 3C phase, is to present conclusions relative to the potential ecological risk posed by the site and provide information useful to risk managers to support remedial decisions related to the site.

    Conducted an ecological study to determine if a complete exposure pathway existed linking residual constituents in onsite tributaries to a receiving creek or directly to ecological receptors at a Superfund site. The purpose of this study was to provide the USEPA, New York State Department of Environmental Conservation (NYSDEC), and United States Fish and Wildlife Service (USFWS) with the best available information to make a risk management decision regarding the potential impacts associated with sediment removal to either the creek or directly to ecological receptors. Based on these results, the NYSDEC and the USFWS recommended to the EPA that sediment excavation is not warranted except for one small area in an onsite tributary. EPA agreed with the conclusion. Thus, a cost-effective exit strategy for the sediments was negotiated that ensured environmentally sound protective strategies and eliminated unwarranted remediation activity through the identification of aggressive remediation goals for realistic risk-reduction.

    Prepared a risk-based plan to evaluate wastefill material that slumped into the Buffalo River, and that remains between the river and a slurry cutoff wall. The overall objectives of the plan was to characterize potential risks to human and ecological receptors, evaluate the effectiveness of remedial measures conducted to date, and identify environmentally sound and cost-effective measures for addressing the wastefill materials. A conceptual site model was prepared to describe the complex interrelationships of soil, groundwater, sediments, and potential receptors by qualitatively evaluating the general exposure scenarios that would apply to the wastefill area. The objective was to estimate the type and magnitude of potential human and ecological exposure to the identified COIs based on current and foreseeable conditions, and to consider all institutional and engineering controls, as well as similar controls that are applicable within the Buffalo River watershed. A risk perspective compared the absolute risks from the wastefill materials to the relative risks from other sources of COIs in the river.

    Benthic ecologist for the Georges Bank Benthic Monitoring Program and the Mid-Atlantic Outer Continental Shelf Environmental Assessment Program for the United States Minerals Management Service’s oil development program.

    Project manager for the Phase 1 Environmental Baseline Study (EBS) and the Health, Safety, and Environmental (HSE) Assessment of Decommissioning of Arzanah Oil Field for Zakum Development Company (ZADCO), and the Phase 2 EBS and On Site Environmental Information Management System (EIMS) and Geographic Information System (GIS) for Abu Dhabi Marine Operating Company (ADMA-OPCO).

    Project environmental scientist O&G projects in Russia (Environmental Status Assessment for Sakhalin Energy Investment Company in Sakhalin Island, estimate of impact on the environment (OVOS)) and Columbia (Environmental Risk Assessment for Release from Amoco Facility in Bogota, impact to indigenous populations and ecological receptors).

    Environmental scientist in Nigeria, Oman, Qatar, and Venezuela where he participated in international O&G technical conferences, and O&G environmental assessment, remediation, and sustainability technology transfer meetings.

    Project manager and risk assessor in Australia for a number of projects as both a third party reviewer, and in conducting the risk assessment. He assessed mangrove and oyster communities for a remediation action plan at a shipyard in northern NSW where the main contaminant of concern is tributyltin (others include lead, copper and zinc) in soils and sediments.   Tom also worked on several projects that included a groundwater to surface water exposure pathway, and examined the spatial and temporal extent of affected aquatic environments downstream from industrial and commercial facilities.  In Mascot, the Botany groundwater management zones and Botany Sand Beds Groundwater Embargo Area were important receptors for discharges to the canal and Cooks River.  Investigations in the Sandy Point/H.M.A.S Cerberus area included development of a conceptual site model of the sediment exposure pathway that included the source of the metals, the release pathways from landfills, and the aquatic and terrestrial ecological species that may be exposed to the metals in the surface waters (including wetlands) of the adjacent creek. Tom has developed and reviewed site-specific soil and groundwater operational and management plans that include protective measures for activities by receptors potentially exposed in soil, groundwater, and surface water.

    Risk assessment support of a PRP cost allocation evaluation for a Superfund landfill site. The goal of the evaluation was to develop a fair and objective discussion of cost allocation for all activities associated with an Order on Consent requiring remedial investigation and feasibility study activities at the site. The Order of Consent is with the State of New York and is considered an approved state action settlement for purposes of 42 USC 9613(f). The evaluation consisted of two phases. The first phase included a review of site files, an internet research, and construction of an Access database summarizing the file chronology, PRP participants, background information on the PRP participants, PRP related constituents of interest, industry-related constituents of interest, and site analytical data. The next phase of the project will include a probability analysis and evaluation of Gore factors and other court approved allocation decision tools to develop a PRP allocation percentage for each of the activities required under the Order of Consent.

    Evaluated potential exposure pathways associated with residual concentrations of PCBs on concrete floors within a redevelopment building in Minneapolis, Minnesota.  The analytical results of the characterization sampling and evaluation of potential exposure pathways were used to propose risk-based cleanup objectives for interior surfaces for both low and high occupancy receptors.

    Multi-phase investigation for delineation and characterization of PCB affected industrial soils at a chemical plant in West Virginia was conducted in accordance with the Part 40 of the Code of Federal Regulations (CFR), Part 761.61, for characterization of potential PCB affected sites within unknown release source.  Remedial strategies potentially include risk-based closure, capping, and institutional controls.  Source identification was a key focus of the investigation due to the unknown release source.

    Corrective action risk-based closure activities in an aluminum foundry in Kentucky were completed for residual PCBs from hydraulic fluid including PCB-sludge in onsite landfill, and PCB-affected groundwater infiltrating basement walls.  Extensive site-specific sampling and regulatory negotiations were essential in focusing potential exposure and risk-based receptor management plan for an acceptable, realistic risk management solution.

    Clean closure of affected soil and groundwater from PCB underground storage tank releases in a former PCB repair facility in Cincinnati, Ohio, included the challenge of PCB-affected soil beneath an active industrial facility.  Institutional controls and risk-based assessment procedures are key to an acceptable exposure level for commercial and utility workers.

    On-going site investigation and risk assessment tasks pursuant to operations at a repair and refurbish facility in Florida for various types of electrical equipment including motors, transformers, and generators.  Site-specific exposure areas were established to facilitate development of receptor-specific cleanup standards for PCBs in surface and subsurface soils, and associated intermittent drainage channel.  Off site delineation includes sensitive human and ecological receptors to evaluate the potential risks associated with the current and probable future land use.

    Risk assessor and project manager for the evaluation and peer review of both human health and ecological risk assessment for chlorinated solvent sites, both in the United States and Australia.  Over half of the risk assessments he has conducted included a chlorinated solvent exposure pathway.  His projects are for clients from the industrial and commercial service industry that routinely used chlorinated solvents such as tetrachloroethylene, trichloroethene, and vinyl chloride.  He has developed site-specific exposure scenarios based on a conceptual site model developed for the risk assessment, especially for industrial and commercial sites that include contaminated land and groundwater resource issues.  Tom has used vapor intrusion modeling to determine the potential risks to indoor receptors from chlorinated solvents in groundwater, soils, and soil gas.   In addition, he has addressed direct contact with affected groundwater including exposures in showers, ingestion, and dermal contact.  In a variety of other risk assessments, exposure areas were developed that were based on the unique exposure duration and frequency parameters for a variety of workers.  These exposure parameters were related to differences in work activities, and incorporated fate and transport models to define exposure point concentrations.  Tom has also addressed the uptake of chlorinated solvents in fish exposed to affected groundwater discharging to fisheries, and to human receptors consuming agricultural products exposed to affected groundwater used to irrigate the crops.  Tom has developed site-specific soil and groundwater management plans that include protective measures for activities by receptors potentially exposed to chlorinated solvents in soil and groundwater.

    Risk assessor for in New Jersey conducting Baseline Ecological Evaluations (BEEs) at sites throughout the state pursuant to the Site Remediation Program (SRP) under the New Jersey Department of Environmental Protection (NJDEP) that includes the Industrial Site Recovery Act (ISRA) and the Hazardous Site Remediation Act.  The BEEs included the evaluation of metals, volatile and semi-volatile organic compounds, polychlorinated biphenyls, and pesticides in soil, groundwater, and surface water and sediments.  In addition, several of these sites also included the evaluation of the human health exposure pathway.  The BEEs for these sites demonstrated acceptable risks to ecological receptors and helped move the sites toward closure.

    In support of litigation activities for his clients, Tom provided expert witness testimony with regards to claims of damage from contaminated commercial properties in Indiana, coordinated legal support pursuant to risk assessment and natural resources damage assessments for a Superfund claim at a gold mining site, opined on a civil action in support of summary judgement for the Welsh landfill Superfund site, and provided forensic evaluations pursuant to a natural resources damage claim for a pipeline client in southwester Pennsylvania.
