Question

Calculate a risk-based groundwater protection standard (in ppm) for the chemical 1,2-dichloroethane. The groundwater comes from a well that is used by a residential homeowner for drinking water. Assume you are determining risk for an average adult who weighs 70 kg. The state where you work has determined that an acceptable Incremental Lifetime Cancer Risk is 1 cancer occurrence per 10^6 people. Use the values for route of intake, exposure frequency, exposure duration, and averaging time in your text. Assume an oral potency factor (cancer slope factor) for 1,2-dichloroethane of 9.2×10^-2 [(mg/kg)/day]^-1.
