Perspective for your consideration …What does it look like when it’s fixed…?
The article entitled … EPA: Toxic fuel in water is not a public threat appears in the 9-23-08 issue of the Az Republic … whereas the article below appears in the 9-33-08 issue of the Washington Post … both explore the tentacles associated with PERCHLORATE a cacogenic ingredient which EPA under George W Bush, in particular, declares is not a public health threat.
I want to take this opportunity to encourage and invite everyone to read this document as it may prove to be an eye opener for you – my input follows this document - …. EPA UNLIKELY TO LIMIT PERCHLORATE IN TAP WATER … By Juliet Eilperin…Washington Post Staff Writer …Monday, September 22, 2008… excerpted …. The Environmental Protection Agency, under pressure from the White House and the Pentagon, is poised to rule as early as today that it will not set a drinking-water safety standard for perchlorate, a component of rocket fuel that has been linked to thyroid problems in pregnant women, newborns and young children across the nation.
According to a near-final document obtained by The Washington Post, the EPA's "preliminary regulatory determination" -- which was extensively edited by White House officials -- marks the final step in a six-year-old battle between career EPA scientists who advocate regulating the chemical and White House and Pentagon officials who oppose it. The document estimates that up to 16.6 million Americans are exposed to perchlorate at a level many scientists consider unsafe; independent researchers, using federal and state data, put the number at 20 million to 40 million.
Some perchlorate occurs naturally, but most perchlorate contamination in U.S. drinking water stems from improper disposal by rocket test sites, military bases and chemical plants. A nationwide cleanup could cost hundreds of millions, if not billions, of dollars, and several defense contractors have threatened to sue the Defense Department to help pay for it if one is required.
The new EPA proposal -- which assumes the maximum allowable perchlorate contamination level is 15 times what the EPA had suggested in 2002 -- was heavily edited by officials of the White House Office of Management and Budget. They eliminated key passages and asked the EPA to use a new computer modeling approach to calculate the chemical's risks.
Under a process the OMB initiated in 2004, federal agencies with an interest in chemicals such as perchlorate, such as the Defense Department, have opportunities to weigh in on the EPA's regulatory decisions before they become final: The Government Accountability Office reported this spring that the Pentagon had pressured the EPA for several years not to regulate perchlorate.
"They have distorted the science to such an extent that they can justify not regulating" the chemical, said Robert Zoeller, a University of Massachusetts professor who specializes in thyroid hormone and brain development and has a copy of the EPA proposal. "Infants and children will continue to be damaged, and that damage is significant."
A reference to those studies in the EPA's proposal was deleted by OMB officials. The document states that establishing a drinking-water standard for perchlorate "would not present a 'meaningful opportunity for health risk reduction for persons served by public water systems,' " but it also reveals that many Americans will be exposed to the compound at levels higher than recommended if nothing is done to remove it. Perchlorate impedes the functioning of the thyroid gland, which produces hormones that foster mental and physical development and control metabolism. The notice indicates that the agency plans to finalize its decision by Dec. 1.
The EPA's assistant administrator for water, Benjamin H. Grumbles, said in a statement yesterday, "Science, not the politics of fear in an election year, will drive our final decision."
"Until then, final numbers and strategies are mere speculation," Grumbles added. "We know perchlorate in drinking water presents some degree of risk and we're committed to working with states and scientists to ensure public health is protected and meaningful opportunities for reducing risk are fully considered."
The Senate Environment and Public Works Committee, chaired by Barbara Boxer (D-Calif.), has endorsed legislation requiring the EPA to set a standard for the chemical and to monitor perchlorate in tap water. Yesterday, Boxer lambasted the agency for refusing to establish a federal exposure standard.
"Perchlorate has been a serious, persistent and widespread problem which threatens the health of our families, especially our children," Boxer said. "For the Bush EPA to walk away from this problem and shrug off this danger is, in my view, unforgivable and immoral."
Federal, state and independent scientists have differed over the years as to what represents an acceptable dose of perchlorate in drinking water, though all have set the bar higher than the non-mandatory level in the EPA's new proposal. In January 2002, the EPA issued a draft risk assessment finding that 1 part per billion should be considered safe; in March 2006, the Massachusetts Department of Environmental Protection set a maximum contaminant level of 2 ppb; last year, California adopted a standard of 6 ppb.
A National Academy of Sciences panel prepared a risk analysis in 2005 that, according to the EPA's traditional models, would produce a protective standard of 1 to 6 ppb. The academy's study came under attack because two of the committee's members had financial ties to defense contractors that face legal liability because of perchlorate disposal.
In the EPA's proposed rule, the administration assumes that perchlorate contamination of 15 ppb is safe. But its regulatory document states that "between 16,000 and 28,000 pregnant women" and 900,000 to 2 million Americans could be exposed to higher levels.
The EPA document also finds that bottle-fed infants would be exposed to more than five times the level the National Academy of Sciences deemed safe -- 700 nanograms per kilogram of body weight per day -- if parents mix formula with drinking water containing perchlorate levels of 15 ppb.
OMB officials said during the drafting process that there was "no need" for detailed data to flesh out a table suggesting that infants would be exposed to perchlorate levels above the academy's recommendation.
To determine safe levels of exposure, the administration opted not to use the academy's "reference dose," a formula that includes a tenfold safety factor to protect children and vulnerable populations, and instead used a computer model developed by the Chemical Industry Institute of Toxicology. EPA officials initially inserted language in the document calling this a "novel approach," but the OMB deleted that language.
Federal officials have yet to determine the extent of perchlorate contamination nationwide, but it is known to be widespread. The GAO, which produced a 2005 report calling for a better federal tracking system for perchlorate, found that limited EPA data show the chemical compound has polluted the soil, groundwater and drinking water in 35 states and the District and has contaminated 153 public water systems in 26 states.
So how does perchlorate play out in Arizona…? Well under the leadership of Governor Napolitano and her ADEQ Director, Steve Owens, we’re going to study this some more in the meantime taking NO action.
Perchlorate has been discovered in drinking wells north of the Az Canal on Tatum while these two have huddled, yet Arizona is NOT prepared to establish a perchlorate quality standard for potable (drinking) water…?
That perchlorate levels exceeding 480 ppb are found in Lake Mead, one of the principal water storage reservoirs for the potable (drinking) water serving metro Phoenix and Tucson and still Arizona under this team sworn to serve and to protect us, they are NOT prepared to establish a perchlorate quality standard for potable (drinking) water…?
As both Napolitano and Owens are attorneys, perhaps they are waiting for the Arizona Supreme Court to make some determination which they can then hide behind…? Or maybe they require a more overt form of proof on the cacogenic qualities of perchlorate, like carcasses of dead, dying, disease, disabled men, women and children…?
It is unconscionably for Arizona’s Governor and her Director of Environmental Quality do nothing on the one hand, while proclaiming to the world at large our water is - safe - and we have all the water we need. The two of you, indeed have learned well the mantra about lying… “If you tell a lie long enough, loud enough and often enough, the people will believe it” … Adolph Hitler

.NO IT IS NOT IN OUR BACK YARD, BUT AT THE VERY LEAST “SIN” CITY IS AT LEAST ACKNOWLEDGING THEY HAVE A PROBLEM WHICH IS MORE THAN ARIZONA IS EVEN WILLING TO CONSIDER …?
LAS VEGAS SUN … 9-29-08 … Joel Schoenmann … ENVIRONMENT…EXCERPTED … Cleaners’ chemical lingers in water, soil …Huge ‘plume’ traced to business under bankruptcy protection …A massive plume of pollution under acres of homes, roads and a golf course in central Las Vegas is the worst of 28 sites in the valley contaminated by the same chemical. The gas-like mass of perchloroethylene, PCE, also known as tetrachloroethylene, or TCE, is emblematic of the intersection of older, less regulated Vegas — indeed, the entire nation — with a world of science that discovers dangers in commonplace practices of years past.
The sites identified by the Nevada Environmental Protection Division include two at Nellis Air Force Base, three at casinos and 19 at current or former dry cleaning businesses. The chemical is widely used for metal degreasing as well as for dry cleaning fabrics. Inhalation of its fumes can cause neurological, liver and kidney problems, according to the EPA. Studies have found that prolonged exposure increases the risk of cancer. The EPA is currently reassessing its potential carcinogenicity. Perchloroethylene remains in use in the dry cleaning industry, though other solvents with less harmful effects are also being used. Dry cleaners are now asked to take special precautions against site contamination to prevent PCE from getting into drinking water. In 1991, California declared perchloroethylene a toxic chemical, and its use will become illegal in that state in 2023.

The Arizona vision to serving and protecting the public as well as providing environmental protection is to not acknowledge that TCE and PERCHLORATE and PCE are carcinogenic and something the public ought to be made aware of and a pro-active posture taken to address and remediate it.
Arizona believes, what the public doesn’t know, can’t hurt them…? And besides, when the Governor and State Legislature don’t address it, then they don’t need to budget for it and you know how they “balance” your state’s budget…?
… People should never be afraid of their government, government should always be afraid of the people …
