* Taken from EPA (1996).
† Concentration that is not expected to cause any adverse noncarcinogenic
effects up to 7 years of exposure, with a margin of safety.
** Drinking water equivalent level. A lifetime exposure concentration protective
of adverse, noncarcinogenic health effects. Assumes all exposure is through drink-
ing water.
†† The concentration of a chemical that is not expected to cause any adverse
noncarcinogenic effects over a lifetime of exposure, with a margin of safety.
*** TNT and RDX are in cancer group C (limited evidence from animal studies
and inadequate or no data in humans) and HMX is in cancer group D (inad-
equate or no human or animal evidence of carcinogenicity).
