#Chromium 6 how to#
We recently wrote a more in depth article on how to filter chromium 6 from water. Reverse osmosis is also a viable way to remove chromium 6 from water for people who are willing to accept the drawbacks, including low flow rate. A new generation of water filters that use chromium 6 removal media are extremely effective at filtering chromium-6 (and other contaminants) from water. Filtration pitchers and common fridge filters DO NOT filter chromium-6 from water. If you want to remove chromium-6 from your water, you need to filter it using a high end water filter. Boiling water also does not reduce/remove chromium-6. Unlike lead, which leaches into water from pipes, chromium-6 comes from the source water itself, so flushing pipes does not reduce concentrations of chromium-6 in drinking water. What Can I Do To Reduce Exposure To Chromium-6? There is no sudden rise in chromium-6, the media coverage is just shining light on an existing situation.
Are the Recent News Articles the Result of a Recent Spike in Chromium-6 Concentrations? Part of the challenge in formulating a proper regulation is that advanced detection procedures and equipment are required to measure things at part per trillion concentrations. To put it in perspective, California (which has tighter regulatory conditions that the EPA) has set a proposed limit of 20 parts per trillion for chromium-6, a level that is 10,000 times lower than what the current EPA regulation is for total chromium. The structure of this regulation is flawed because it treats non-toxic forms of chromium in the same manner as highly toxic chromium-6. In 1991 EPA set a Maximum Contaminant Level (MCL) for total chromium (all kinds) in drinking water of 200 parts per billion. Unfortunately, chemicals containing chromium-6 are useful in a number of industrial processes, which means that chromium-6 can enter drinking water supplies through waste streams that enter rivers and ground water. Industries that generate chromium-6-containing waste include: steel production, leather tanning, textile manufacturing, wood preservation, and electroplating.
#Chromium 6 movie#
In popular culture, chromium-6 is the chemical that was at the center of the Erin Brockovich story, which was made into a movie starring Julia Roberts. There is no reason to be throwing away stainless steel cookware!Ĭhromium-6 (or hexavalent chromium), on the other hand, is an extremely toxic form of chromium, and is known to cause cancer, even at very low concentrations. These are the types of chromium used to make stainless steel and are found in dietary supplements. chromium metal, trivalent chromium) are not toxic. So what is chromium-6? Chromium comes in a variety of chemical “flavors.” Most forms of chromium (e.g. Is Chromium-6 the Same Thing as “Regular” Chromium? The purpose of this article is to address a lot of these FAQs, including the answer to "what is chromium-6?," and to discuss how to remove chromium 6 from drinking water. Since The Environmental Working Group recently released a report about the prevalence of chromium-6 in drinking water supplies, our email and support line have been filled with questions about the toxic heavy metal.
