The reply posted that says the EPA cleanup level for residential under
Superfund is 400 ppm is not  correct.   The 400 ppm is a soil screening 
level, not a cleanup level.   We use the 400 ppm essentially to decide 
whether to go forward with further site characterization.   As part of 
our evaluation we run the results through a model (the IEUBK) to 
determine the risk and the appropriate cleanup level based on the 
Superfund risk range.   Consequently, due to site differences one could 
have a cleanup level of 300 ppm, 400 ppm,  500 ppm or higher.
