For years, California officials have been working to set the nation's first-ever safety standard for the carcinogenic metal hexavalent chromium (chromium-6), commonly found in the state's drinking water. Last week (Dec. 31), after specifically evaluating the pollutant’s threat to infants, public health officials sharply lowered their proposed “public health goal” to 0.02 parts per billion (ppb) of chromium-6 in drinking water.

After our May 16 blog about consultant Dennis Paustenbach's possible appointment to an EPA panel on asbestos, we received a letter from Dr. Paustenbach's attorney. It says our use of the word "fraud" in describing the involvement of Dr. Paustenbach's company, ChemRisk, in the publication of a since-retracted study on chromium-6 in drinking water was "false and defamatory."

EWG is disturbed to learn that Dennis C. Paustenbach is on the "Short List" of potential appointees to the Asbestos Panel of the EPA Science Advisory Board. EPA's Ispecifies that appointees to the Panel should display "absence of financial conflicts of interest" and "absence of an appearance of a lack of impartiality." Based on evidence of his work for defendant corporations in lawsuits over asbestos exposure, his studies that consistently aim to refute or minimize the scientifically established risks of asbestos exposure, and other evidence detailed below of a lack of adherence to scientific and professional ethics, it is clear that Dr. Paustenbach is unfit to serve on the Panel.

He's back. Dennis C. Paustenbach, a.k.a. Dr. Evil, the science-for-hire consultant who rarely met a chemical he didn't like, is on the short list of potential appointees to the EPA Science Advisory Board Asbestos Panel. The panel has a crucial task: advising EPA's upcoming risk assessment for airborne asbestos, a killer that takes 10,000 American lives a year.

Dear Dr. Paustenbach: We were stunned to read in The Scientist your rationale for hiding the funding source of the chromium-6 article under the names of JianDong Zhang and ShuKun Li in the April 1997 Journal of Occupational and Environmental Health (JOEM). Essentially your defense is, "Everybody does it."
