Problem: The following questions are based on the CT DEEP Remediation Standards. What is taken into consideration for the calculation of the Direct Exposure Criterion for a carcinogenic substance? Draw the chemical structure of 1,1,1-Trichloroethane, 1,1,2-Trichloroethane, Trichloroethylene, and Vinyl Chloride. What are the groundwater cleanup standards for these compounds? Why do you think they are so different given the similar chemical structure? What is the direct exposure residential remediation standard for Benzene? What is the GA pollutant mobility standard for Benzene? Why are these different? (hint: think about the potential means of exposure to humans) Based on the Superfund Site Case Study youtube video, what are the steps that you go through for a Remedial Assessment and Cleanup?
