MMU releases water quality report

Tuesday, May 5, 2009

In "Water Quality Report 2008," published April 2009, Marshall Municipal Utilities reported the results of a "source water assessment" by Missouri Department of Natural Resources, which looked for potentials for contamination of MMU's wells.

"In the ... report, we basically report only on those contaminants that we detect that are regulated," said MMU Environmental Services Director Ginny Ismay.

She said MMU added the unregulated substances calcium, magnesium, sodium and potassium to the report.

"We put them in anyway for quick and easy reference," Ismay added.

As stated in the publication, "(d)rinking water, including bottled water, reasonably may be expected to contain at least some small amount of contaminants. The presence of contaminants does not pose a health risk."

The concentration of barium in MMU's wells was reported as 0.044 parts per million, or ppm, which is below the maximum contaminant level, or MCL, of 2.0 ppm.

Fluoride, which is both naturally occurring in water and added to "promote strong teeth," according to the publication, was found to be present at an average of 1.06 ppm. The MCL of fluoride is 4.0 ppm.

Nitrate is toxic to humans in that it renders hemoglobin unable to carry oxygen and is responsible for so-called "blue baby syndrome." In MMU's wells, nitrates were found in concentrations of less than 0.12 ppm, far below the MCL of 10.0 ppm.

Combined nitrate and nitrites also have their MCL set at 10.0 ppm and were found in concentrations of 0.12 ppm.

Haloacetic acids were found in concentrations of 24.1 parts per billion, or ppb, which is less than half the MCL of 60.0 ppb.

Concentrations of total trihalomethanes were found at levels of 54.8 ppb, below the MCL of 80.0 ppb.

Both haloacetic acids and trihalomethanes are a by-product of drinking water disinfection.

Chlorine, which is added to control levels of microbes in water, was found at an average residual level of concentration of 1.36 ppm, which is lower than the maximum residual level of 4.0 ppm. This was the only substance not analyzed in a DNR-certified laboratory, and was instead analyzed onsite by MMU personnel, according to the publication.

Other unregulated contaminants were also found. Calcium was detected at a concentration of 19.5 ppm, magnesium at 17.9 ppm, potassium at 3.47 ppm and sodium at 23.0 ppm.

Copper and lead were found in the system, as is fairly common in areas with older buildings, due to the metals that comprise piping in those buildings.

Copper was found in concentrations at or below 0.081 ppm in 90 percent of areas checked. The MCL for copper is 1.3 ppm.

Lead was found in concentrations at or below 5.2 ppb in 90 percent of areas checked. The MCL for lead is 15 ppb.

Susceptibility to contaminants in drinking water varies from person to person. Those at the greatest risk, according to the document, are the very young and very old and those with compromised immune systems, including persons undergoing chemotherapy, persons with AIDS and those who have undergone organ transplants.

Ismay said consumers can go to the MMU Web site to see determined concentration levels of inorganic chemicals, volatile organic chemicals and synthetic organic chemicals, as well as "other analysis."

"It will show everything that we test for, the testing frequency, when it was last analyzed," she said.

The document directs consumers who want more information about contaminants to call Environmental Protection Agency's Safe Drinking Water Hotline at 1-800-426-4791.

Over 2,440 professionals urge the US Congress to stop water fluoridation until Congressional hearings are conducted, citing scientific evidence that fluoridation, long promoted to fight tooth decay, is ineffective and has serious health risks. See statement: http://www.fluorideaction.org/statement.....

Also, eleven Environmental Protection Agency employee unions representing over 7000 environmental and public health professionals called for a moratorium on drinking water fluoridation programs across the country, and have asked EPA management to recognize fluoride as posing a serious risk of causing cancer in people.

Last election day, 53 US cities rejected fluoridation joining a growing list of communities saying "No," to fluoridation.

-- The Canadian Association of Physicians for the Environment, Canada's leading voice on environmental health issues, released a statement opposing fluoridation.

-- The National Kidney Foundation dropped its fluoridation support replacing it with this caution: "Individuals with CKD [Chronic Kidney Disease] should be notified of the potential risk of fluoride exposure."

-- Researchers reporting in the Oct 6 2007 British Medical Journal indicate that fluoridation never was proven safe or effective and may be unethical.

-- "A qualitative review of ...studies found a consistent and strong association between the exposure to fluoride and low IQ," concluded Tang el al., in "Fluoride and Children's Intelligence: A Meta-analysis" in Biological Trace Element Research

-- Scientific American editors wrote in January 2008, "Some recent studies suggest that over-consumption of fluoride can raise the risks of disorders affecting teeth, bones, the brain and the thyroid gland"

-- A study in the Fall 2008 Journal of Public Health Dentistry reveals that cavity-free teeth have little to do with fluoride intake. Researchers report, "The benefits of fluoride are mostly topical...while fluorosis is clearly more dependent on fluoride intake."

A Tennessee State legislator who is also an MD is urging all Tennessee Water Districts to stop fluoridation, reported a Tennessee newspaper on 11/29/08. At least 30 Tennessee water districts have already complied with his request.

On 1/5/09, the Burlington Board of Health recommended that Burlington cease fluoridation because fluoridation can harm some people.

On 2/10/2009 Skagit County, WA officials reversed their 2007 fluoridation decision.

On 3/3/2009, Plainfield, Vermont bans fluoridation.

Nobel Prize winner in Medicine, Dr. Arvid Carlsson, says, "Fluoridation is against all principles of modern pharmacology. It's really obsolete."

An Online Action Petition to Congress in support of the Professionals' Statement is available on FAN's web site, http://congress.fluorideaction.net

Fluoride jeopardizes health - even at low levels deliberately added to public water supplies, according to data presented in a 2006 National Academy of Sciences' (NAS) National Research Council (NRC) report. Fluoride poses risks to the thyroid gland, diabetics, kidney patients, high water drinkers and others and can severely damage children's teeth. At least three panel members advise avoiding fluoridated water.
