What is Chromium 6?

Hexavalent chromium (chromium(VI), Cr(VI), chromium 6)
refers to chemical compounds that contain the element chromium in the +6 oxidation state (thus hexavalent).1)Hexavalent Chromium:

Chromium-6, the cancer-causing chemical best known for its role in the Erin Brockovich story, has been found at higher-than-recommended levels in the tap water supplying two-thirds of all Americans, according to a report from the Environmental Working Group.

“The difficulty with chromium-6 is how to set a standard to protect human health during windows of development,” Andrews said.

Even in small amounts, chromium-6 can cause skin burns, pneumonia, complications during childbirth and stomach cancer. 2)What is chromium-6 and how did it infiltrate America’s drinking water? :



In Chicago's first ever testing for the toxic metal contaminant, results show that the city's local drinking water contains levels of hexavalent chromium more than 11 times higher than the health standard set in California in July 2011. The results of the test showed that the water which is sent to over 7 million residents had average levels of 0.23 ppb of the toxic metal. California's Office of Environmental Health Hazard Assessment designated the nation's new "public health goal" limit as 0.02 ppb. Echoing their counterparts in other cities where the metal has been detected, Chicago officials stress that local tap water is safe and suggest that if a national limit is adopted, it likely would be less stringent than California's goal. The Illinois Environmental Protection Agency (Illinois EPA) has developed a chromium(VI) strategic plan which outlines tasks in order to reduce the levels of chromium(VI) in Illinois' drinking water. One of which is to work with the U.S. EPA to provide significant technical assistance to the City of Chicago to ensure they quickly develop an effective chromium(VI) specific monitoring program that makes use of the U.S. EPA-approved methods.3)Hexavalent Chromium:

Chicago's Chromium-6 Reports:

The Chicago Department of Water Management has begun quarterly monitoring for chromium-6. Federal regulators and the drinking water industry are presently researching chromium-6, also referred to as hexavalent chromium, in an attempt to discover at what levels it might pose a health risk in drinking water. Chromium-6 is a naturally occurring contaminant and an industrial chemical that has been linked to cancer.

Currently, there are no regulations or requirements to test for chromium-6 in drinking water. The EPA did issue a guidance statement on January 11, 2011. That statement recommended surface water systems like Chicago sample the source water, plant treated water, and water in the distribution system on a quarterly basis.

The Chicago Department of Water Management is voluntarily following the EPA’s recommendations. The EPA is developing a risk assessment for chromium-6 via ingestion; results should be available later this year. The risk assessment will form the basis of any regulations that may be developed for this element. The Chicago Department of Water Management is prepared to respond, immediately to any new regulations, for chromium-6, to protect public health and meet federal and state water quality standards.4)Chicago's Chromium-6 Reports:

ALERT: Bottled Water Recall

Water recalled after possible E.coli contamination

A bottling company has announced a voluntary recall of several brands of bottled water after E.coli was found in one of its source springs.

On June 10th, Far Away Springs in Auburn, Pennsylvania, which provides water to Niagara, discovered contaminants, namely E Coli, in their water source. They failed to notify their partners about this contamination in a timely manner, and now Niagara is recalling thousands of their bottled water products “out of an abundance of caution” for the safety of consumers. The company stressed that no contamination has been found in its product or at its plants.

Niagara Bottling is voluntary recalling water bottled in its Pennsylvania plants between June 10 and June 18, 2015 and sold under these brands:

  • 7-Eleven
  • Acadia
  • Acme
  • Big Y
  • Best Yet
  • Morning Fresh
  • Niagara
  • Nature’s Place
  • PriceRite
  • Shaw’s
  • ShopRite
  • Superchill
  • Western Beef Blue
  • Wegman’s

The affected products have codes that begin with the letter F or A. The first digit after the letter indicates the number of the production line. The next two numbers indicate the day, then the month in letters, the year and then the time, based on a 24-hour clock.

Example: A610JUN15 2000

According the Niagara’s official public notice, bottled water with these codes should be boiled for at least one minute and then cooled before it is consumed.

Again and again we’re seeing that the only way to be completely certain about what is in the water you and your family drink, is to take matters into your own hands. With a premium water distiller in your home you can rest assured your drinking water is safe.

Summer Brings Threat of Toxic Blue-Green Algae

by Al Meder

Each year one is likely to read of the “Toxic Blue Green Algae” that appear in many of our lakes. Last summer, Lake Erie hit the headlines and the 400,000 residents of Toledo could not use their tap water at all for three days.

With summer now upon us, the publicity is sure to rise again, and not just around Lake Erie. Most states have this algae problem, as I have pointed out in an earlier blog.

To one who is educated in biology, there is not one problem here but rather two. While green algae blooms occur frequently, there is another culprit which is often referred to as “blue-green algae” when technically it is not. The culprit is in fact bacteria with the name “cyanobacteria”. Cyanobacteria are also green and the toxins produced by the cyanobacteria are what the authorities in Toledo last summer were concerned about. The cyanobacteria and algae get grouped together by news reporters because both are blue-green in color.

But cyanobacteria are a serious concern.

“Cyanobacteria can produce neurotoxins, cytotoxins, endotoxins, and hepatotoxins (i.e. the microcystin producing bacteria species microcystis), and are called cyanotoxins” ……..Wikipedia.
The cyanobacteria were the reason the authorities cautioned residents against “boiling the water” before drinking it. Boiling, in fact, concentrates the cyanotoxins in the water being boiled while the steam produced is actually free of toxins.

We had the science department of the University of Nebraska test this water last year after it had been put through a Pure Water distiller, and as we expected, “distillation effectively lowered the concentration of the three cyanotoxins below instrument detection limits.”

It is for this reason that those consumers in Toledo who had a well-designed water distiller, could keep on drinking the water from Lake Erie when other residents could not.
