Chromium Six

Hexavalent Chromium Is Statewide Concern.
Each location had more than 0.02 parts per billion, however all were compliant with maximum contaminate level guidelines. Confused?

Purity Bay Provides Solutions To Address Chromium 6

There are Several Forms of Chromium, One Is Good & One Is Bad.
Chromium occurs in the environment is primarily in one of two valences. Chromium(VI) and chromium(III) are used for chrome plating, dyes and pigments, leather tanning, and wood preserving. A less common form used for making steel is metallic chromium(Cr 0).

The health hazards associated with exposure to chromium are dependent on its state of oxidation.
Nearly 70 million Americans are believed to have hexavalent chromium in their drinking water. In fact, a study of U.S. tap water by the Environmental Working Group detected chromium-6 in the drinking water of 31 of 35 cities tested.

Our Leaders weighed the health factors against costs of removing the Chromium(VI). We can still expect our water bill to increase significantly to meet the currently inadequate guidelines.
The Good: Trivalent Chromium (III)
Occurs naturally and is an essential nutrient.
According to Web MD: “Drinking hard tap water supplies chromium to the body.” Web MD also states: “Chromium is a mineral our bodies use in small amounts for normal body functions, such as digesting food. It exists in many natural foods including brewer’s yeast, meats, potatoes (especially the skins), cheeses, molasses, spices, whole-grain breads and cereals, and fresh fruits and vegetables.” However, Web MD is referring to Chromium(III).

For most people eating food that contains chromium(III) is the main route of intake, because it occurs naturally in many vegetables, fruits, meats, yeasts and grains. Chromium(III) is an essential nutrient for humans and shortages may cause heart conditions, disruptions of metabolisms and diabetes. But the uptake of too much chromium(III) can cause health effects as well, for instance, skin rashes

Chromium (VI)/hexavalent Chromium : A DANGER TO HUMAN HEALTH!
The Most Important Thing You Can Do Is To Limit Your Exposure To The Contaminated Water.
This is the same toxic element in the movie Erin Brockovich. This movie was based on real life events. Hexavalent Chromium is the same cancer causing contaminate that was called the “safe” chromium, by PG&E and a judge ordered a settlement of $333 million dollars in 1993.

How does chromium(VI) get into my water supply?

Chromium(VI) can occur naturally might be present in some groundwater aquifers. Most Chromium(VI) has reached water supplies from industrial uses such as metal plating, stainless steel production, etc. Chromium compounds have been released to the environment via leakage, poor storage, or improper disposal practice at many places with this issue. In short, chromium(VI) occurs in nature, but it’s also a by-product from industry, such as chrome-plating.

According to article by ATSDR :

“It can be absorbed by the lung and gastrointestinal tract, and even to a certain extent by intact skin. Human occupational experience clearly indicates that, when inhaled, chromium compounds are respiratory tract irritants, resulting in airway irritation, airway obstruction, and lung, nasal, or sinus cancer. Dose, exposure duration, and the specific compound involved can determine chromium’s adverse health effects.”
Dose, Exposure Duration, And General Sensitivity Of The Individual involved Can Determine Chromium’s Adverse Health Effects.

What are the health risks from bathing/showering in water contaminated with Chromium(VI)? Skin exposure to high levels of Chromium(VI) may cause skin irritation. In some individuals, skin exposure to Chromium(VI) may cause allergic contact dermatitis. A scientific study showed that a person is not exposed to a significant amount of Chromium(VI) from breathing steam while showering (Finley et al. 1996). This is only one study.

“The respiratory tract is the major target organ for chromium(VI) following inhalation exposure in humans. Shortness of breath, coughing, and wheezing were reported in cases where an individual inhaled very high concentrations of chromium trioxide,” according to the ATSDR.
“Other effects noted from acute inhalation exposure to very high concentrations of chromium(VI) include gastrointestinal and neurological effects, while dermal exposure causes skin burns in humans,” also stated by ATSDR.

Chromium Can Be Measured in Hair, Urine, and Blood. If you are Experiencing any of The Following, Inform Your Doctor!

Chromium Allergic Dermatitis Is Characterized By:
dryness, erythema, fissuring, papules, scaling, small vesicles, and swelling

  • Other Symptoms to Look Out For are:
  • Cancers: lung, nasal, sinus, respiratory, lung (if exposed greater than 20 years)
  • Breathing problems, such as asthma, cough, shortness of breath, or wheezing.
  • Pulmonary sensitization
  • Severe dermatitis & painless skin ulcers
  • Renal tubular damage
  • Liver abnormalities
  • Cardiovascular collapse

Again, please see a doctor and test your chromium levels if you are concerned with a possible exposure to Chromium(VI). A private laboratory can also provide testing of your drinking water.


Happy Customers

Exceptional Water Quality!

“Tyler and Jaime at Pure Solutions are professional in every detail. They help to find out what is needed and wanted and deliver a workable, affordable solution to handle any problems with the water. Highly recommended.”

Best Product on Market!

“My father has built houses for over 40 years and he has assured me that a water processor is an essential addition to a healthy home (and it adds to the resale value). I know for a fact that we made the right decision when we purchased our Purity Bay water processor.”

Best Decision I Made!

We have purchased the Purity Bay water filter system and it has done wonderful things for our family: our water is softer; water boils and heats faster (we had to turn our water heater temperature down); clothes are softer and easier to iron; we use less soap, shampoo and conditioner, which in turn saves us money.
