California Sets Limits for Perchlorate Levels in Water

>From <> 3/19/04

California First State to Announce Perchlorate Limits

Last week, California regulators announced a "public health goal"
that will lead to formal regulations restricting levels of
perchlorate -- a toxic chemical used in rocket fuel that damages
thyroid glands -- in the water supply, thus becoming the first state
to define such standards. The recommendation, 6 parts per billion,
prompted much debate. Environmental groups had hoped for a more
stringent standard, like the 1 ppb standard the U.S. EPA has
provisionally adopted, pending a more comprehensive study by the
National Academy of Sciences. The California Department of Health
Services will now develop an official regulatory standard, taking
into account the recommendation, the NAS study, and the costs of
cleaning widely polluted water supplies like the lower Colorado
River. The Pentagon is lobbying the state -- and the U.S. EPA -- not
for the 1 ppb standard, nor the 6 ppb, but for ... 200 ppb. We wish
that were a typo.
