EPA Seeks Comment on Preliminary Perchlorate Drinking Water Decision
Agency Plans to Issue a Perchlorate Health Advisory

(Washington, D.C. – Oct. 3, 2008) The U.S. Environmental Protection Agency conducted extensive review of scientific data related to the health effects of exposure to perchlorate from drinking water and other sources and found that in more than 99 percent of public drinking water systems, perchlorate was not at levels of public health concern. Therefore, based on the Safe Water Drinking Act criteria, the agency determined there is not a "meaningful opportunity for health risk reduction" through a national drinking water regulation.

The agency is seeking comment on its preliminary determination not to regulate perchlorate in drinking water at a national level. EPA will make a final determination for perchlorate after considering information provided in the 30-day public comment period.

While fewer than one percent of the drinking water sources have perchlorate levels above the health reference level, EPA is committed to working with states and localities to ensure public health is protected. States have the right to establish and enforce drinking water standards and EPA encourages state-specific situations to be addressed at the local level. EPA intends to issue a health advisory at the time it issues its final regulatory determination for perchlorate, to assist states with their local response.

A regulatory determination is a formal decision by EPA as to whether it should initiate development of a national primary drinking water regulation for a specific contaminant under the Safe Drinking Water Act. EPA has drinking water regulations for more than 90 contaminants. Every five years, EPA develops a Contaminant Candidate List of contaminants to consider for regulation and then makes regulatory determinations on some of the contaminants based on scientific information on health effects, occurrence in drinking water and the opportunity for risk reduction.

A health advisory provides technical guidance to federal, state, and other public health officials on health effects, analytical methods and treatment technologies associated with drinking water contamination. Health advisories also contain guidance values that are concentrations of a contaminant in drinking water that are likely to be without adverse health effects.

TEMPERATURES GETTING COLDDER/ARCTIC ICE INCREASING?

     Columnist Debra J. Saunders has a column worth reading in today's San Francisco Chronicle:

Here's another reason why people don't trust newspapers. When science reporters write about, say, hormone therapy or drinking red wine, they report on studies that find that hormones or red wine can be good for you, as well as studies that suggest otherwise. Any science involving complex organisms is rarely black and white.

When it comes to global warming, newspapers play up stories that reinforce the prevalent the-sky-is-falling belief that global warming is human-caused and catastrophic. But if a study or scientist does not portend the end of the world as we know it, it rarely rates as news.

"It's not even science any more; it's anti-science." [David] Bellamy [an Australian botanist] notes that official data show that "in every year since 1998, world temperatures have been getting colder, and in 2002, Arctic ice actually increased." Exhibit B: MIT Alfred P. Sloan Professor of Atmospheric Sciences Richard S. Lindzen recently wrote, "There has been no warming since 1997 and no statistically significant warming since 1995."
