States Eye New Perchlorate Standards Amid Uncertainty Over EPA Action

摘要

Several states are stepping up efforts to set drinking water standards for the rocket fuel ingredient perchlorate given uncertainty about when, or if, EPA will pursue regulatory options to limit the risks of exposure to the chemical.rnNew Jersey officials are backing away from an earlier decision not to set a drinking water standard for perchlorate and saying they may begin a new rulemaking to establish a standard based on a pending final EPA analysis of the science on the chemical's risks due out this summer. Separately, California's health hazard office is expected to soon issue its response to an activist petition asking it to strengthen its existing perchlorate drinking water limit.
