"[T]he groupings in Regulatory Guide 1.86 were primarily based on 
instrumentation detectability and are quite broad. . . ."

"Also, since detectability, inhalation (through association with maximum 
permissible concentrations in air), and ingestion (through association with 
maximum permissible concentrations in water) were primarily bases for 
Regulatory Guide 1.86, . . . ."
