A groundwater well is used to provide drinking water for an elementary school where children drink an average of 3 liters of water per day. The aquifer sits downgradient of an abandoned pesticide plant that is now a Superfund site. Water there is being treated (via pump and treat) before being re-injected into the aquifer. Assume no significant degradation between the abandoned site and the schoolyard. Assume that 12% of the chemical is absorbed through the stomach wall and apply a safety factor of 10. Use Table 8-1 of the EPA Exposure Factors Handbook for the age range of a child: 6 to <11 years of age.... From table 8-1 Body Weight is 31.8kg

The primary pesticide of concern is alachlor, CASRN 15972-60-8:

NOAEL=1 mg/kg-day RFD = 1x10^-2 mg/kg-day

What should be the minimum remediation goal (mg/l) of the treatment effort? (4 pts) What would be the potential health effect(s) of not reaching the goal? (4 pts)
