The Environmental Working Group (EWG), a nonprofit research and advocacy organization, analyzed more than 60,000 samples of drinking water taken from taps across the United States. Thousands of local water utilities gathered the samples from 2013 to 2015 as part of a U.S. Environmental Protection Agency (EPA) program.
Over 75 percent of the water samples contained levels of chromium-6 above 0.02 parts per billion. That’s the threshold at or below which California state scientists say chromium-6 would pose a “negligible” cancer risk over a lifetime of consumption.
“Chromium-6 is so widespread, in terms of its distribution across drinking water sources,” David Andrews, a senior scientist at EWG, told Mashable.
There are two main types of chromium compounds. Chromium-3, or trivalent chromium, is a naturally occurring compound and an essential human nutrient. Chromium-6 also occurs naturally, but is manufactured for use in steel making, chrome plating, manufacturing dyes and pigments, preserving leather and wood and, as in the Brockovich case, lowering the temperature of water in the cooling towers of electrical power plants. Chromium-6 is also in the ash from coal-burning power plants, which is typically dumped in unlined pits that a 2011 report by the nonprofit Earthjustice said may threaten hundreds or thousands of water supplies and private wells. And recent research has suggested that some methods of treating water supplies to remove other contaminants may actually increase levels of chromium-6.
Human studies by government and independent scientists worldwide have definitively established that breathing airborne chromium-6 particles can cause lung cancer, and the U.S. Occupational Safety and Health Administration sets strict limits for airborne chromium-6 in the workplace. Whether inhaled or ingested, it can also cause liver damage, reproductive problems and developmental harm. Studies have found that exposure to chromium-6 may present greater risks to certain groups, including infants and children, people who take antacids, and people with poorly functioning livers.
Just another reason why we promote reverse osmosis water for home filtration. To see if your area is effected with Chromium-6 click the above link to view the map. Clean water is essential for good health. I don’t want trace amounts of pharmaceuticals, heavy metals, fluoride, or any unnecessary chemicals in my water. If you are concerned about heavy metal toxicity from either water source or other environmental sources a hair analysis is a good tool to start with for an evaluation. Many patients of mine I find are being exposed to certain toxic metals and absorb them like a sponge. There are different chelation angles to help rid individuals who have these toxic metal build ups in their body. Between chemicals and heavy metal exposures it is just very important to make sure your detox pathways are open to clear these.
