Calculate a risk-based groundwater standard (in ppb) for the chemical 1,2-dichloroethane for a residential homeowner where the person’s well used for drinking water is contaminated with 1,2-dichloroethane. Assume the risk is for an average adult who weighs 70 kg. The state where you work has determined that an acceptable risk is one cancer occurrence per 106 people. Use the values for route of intake, exposure frequency, exposure duration, and averaging time provided for residential use in the following table 6.14

Calculate a risk-based groundwater standard (in ppb) for the chemical 1,2-dichloroethane for a residential homeowner where the person’s well used for drinking water is contaminated with 1,2-dichloroethane. Assume the risk is for an average adult who weighs 70 kg. The state where you work has determined that an acceptable risk is one cancer occurrence per 106 people. Use the values for route of intake, exposure frequency, exposure duration, and averaging time provided for residential use in the following table 6.14. Assume an oral slope factor for 1,2-dichloroethane of 9.2x10-2 per (mg/kg)/day.
