Human Health Risk Assessment representative project experience includes:
Investigation and Human Health Risk Assessment Review for RCRA Closure in Irvine, California
Technical review of the RCRA Facility Investigation, including human health risk assessment and RCRA Corrective Action Measures Study for a former commercial facility in Irvine, California. The former landowner conducted operations that resulted in the subsurface contamination of the property with chlorinated solvents in soil and groundwater, eventually including the closure of the facility under the RCRA Facility program of the Department of Toxic Substances Control. Working for the current landowner, technical review and regulatory agency negotiations have been conducted to facilitate development plans at the property.
Human Health and Ecological Risk Assessment for Former Liquid Bulk Terminal
Development of human health and ecological risk assessments for a former liquid bulk terminal located in Redwood City along the San Francisco Bay. The property includes multiple above ground bulk storage tanks and associated equipment. The risk assessments were conducted to address both the RCRA closure of permitted waste units, as well as the entire facility. The human health risk assessment included evaluation of potential indoor air exposures, while the ecological risk assessment included an evaluation of potential exposure to on-site and nearby ecological habitat. The risk assessments have been reviewed and approved by the Department of Toxic Substances Control.
Human Health and Ecological Risk Assessment for Stockton Channel Redevelopment
Development of a human health and ecological risk assessment for a five-parcel property located along the Stockton Channel. The property was targeted for redevelopment to include recreational and commercial/industrial land uses. In addition to assessment of risks for each parcel, remedial action objectives for soil and groundwater were developed. The risk assessment document was reviewed and approved by the Department of Toxic Substances Control.
Human Health Risk Assessment for Former Mare Island Naval Shipyard
Development of human health risk assessments for 12 sites of a former naval shipyard in Northern California where the area is scheduled for future public reuse including potential residential, commercial, industrial and construction activities. Soils at the sites were affected by PCBs, pesticides, petroleum hydrocarbons, volatile organic compounds, polynuclear aromatic hydrocarbons and heavy metals. As a part of the follow‑on work, human health risk assessments were also developed for two Investigation Restoration (IR) sites at the former naval shipyard with chemical-affected soil and groundwater.
Human Health Risk Assessment for Former Lock Factory
Risk assessment project management of a baseline and a separate redevelopment human health risk assessment for a former industrial facility located in the southern portion of San Francisco under the oversight of the Department of Toxic Substances Control. Volatile organic compounds and metals have affected subsurface soils and shallow groundwater. The baseline human health risk assessment included evaluation of potential risks during operation of the industrial facility. The redevelopment human health risk assessment was developed to address potential future commercial and residential exposures based upon a no remedial action alternative for the now closed facility and future redevelopment Site.
Human Health Risk Assessment for RCRA Closure
Development of a human health and ecological risk assessment for the closure of a RCRA Solid Waste Management Unit located within a former chemical manufacturing facility in Fontana, California where soils were affected by metals. On-site and off-site receptors were evaluated to confirm the adequacy of the site remediation activities conducted for the closure. The RCRA closure was accepted and the site was redeveloped as part of the California Speedway Facility.
Human Health Risk Assessment for West Oakland Redevelopment
Development of a human health risk assessment for a residential and commercial redevelopment project in West Oakland. The site had residual concentrations of metals and organochlorine pesticides in soil, as well as volatile organic compounds in shallow groundwater. Risk-based soil cleanup levels were developed for single family residential, multi-family residential and commercial land use. A combination of soil excavation and mitigation measures to address potential human health risks were implemented to allow the redevelopment project to continue with construction.
Human Health and Ecological Risk Assessment for Union Point Park in Oakland, California
Development of a screening-level human health risk assessment and ecological risk assessment for the Union Point Park Site in Oakland, California as part of the soil and groundwater investigation for the Site. Because the Port of Oakland was proposing to redevelop the property as a public park, potential receptors were identified to focus the evaluation on most probable exposure scenarios rather then default scenarios.
