Risk Assessment for a 1,400-Acre Historical Chemical Production Site in Ohio
- Challenge: A historical chemical production site in Painesville, Ohio, once included a chromate production facility, coke oven, carbon tetrachloride plant, cement plant, soda ash plant and research laboratory. The site needed to be investigated for residential, recreational and commercial/industrial redevelopment in accordance with the Ohio EPA (OEPA) Voluntary Action Program. Cardno ChemRisk was asked to assist.
- Approach: Cardno ChemRisk performed a complex risk assessment that involved multiple chemicals, media and exposure scenarios. The work included an end-use specific human health risk assessment for each study area and an investigation of the ecological impacts to the Grand River and Lake Erie.
- Findings: Human health risk was determined for various residential, recreational and commercial redevelopments under the OEPA Voluntary Action Program (VAP). Chemicals of concern in the study areas included carcinogenic Polycyclic Aromatic Hydrocarbons (c-PAHs), Polychlorinated Biphenyls (PCBs), vinyl chloride, mercury, arsenic, benzene, naphthalene, toluene and pesticides.
- Value: Cardno ChemRisk assisted in negotiating appropriate exposure scenarios with the OEPA and provided a quantitative assessment of risk that helped both the client and the OEPA develop an appropriate remediation strategy to support property redevelopment in a health-protective manner.
