City water supplies around the U.S. were recently tested for a particular cancer-causing compound. An analyze released by the EWG released Monday found that hexavalent chromium contaminated municipal water supplies in 31 of 35 locations tested. Hexavalent chromium, also known as chromium-6, achieved notoriety within the film “Erin Brockovich.”.
What hazards exist with hexavalent chromium
The Environmental Working Group states that the hexavalent chromium gets into our water supply by being dumped by steel and pulp mills, metal-plating and leather-tanning industries. EWG paid labs to test normal water in 35 locations known to be contaminated by the cancer-causing compound, which leaches into groundwater from eroding soil. Stomach cancer and chromium-6 have been found by An Environmental Working Group scientist to have a correlation. The highest levels of hexavalent chromium were found in Norman, Okla., Honolulu, Hawaii, Riverside, California, Madison, Wis., and San Jose, Calif.
The investigation into chromium-6
The Environmental Working Group analyze is the 1st nationally assessment of hexavalent chromium in municipal water supplies. As the Environmental Protection Agency is intending to regulate the limit of chromium-6 in water the analyze went public. The National Institutes of Health classified hexavalent chromium as a possible cause of cancer back in 2008. 0.06 parts per billion is the limit CA already put on hexavalent chromium back in 2009. The EWG research found that in Norman pubic drinking water exceeded that limit by 200 times. The limit CA put on their water was exceeded in 25 of the 35 cities used for the research.
Environmental Working Group advice: reverse osmosis water filtration
Hexavalent chromium is the cancer-causing compound that starred within the movie “Erin Brockovich.” Chromium 6 was in the water supply in Hinckley, California, and Brockovich in real life did sue Pacific Gas and Electric for contamination and won. The award to Brockovich was over $330 million in damages. Until the EPA regulates hexavalent chromium in drinking water, the EWG suggests a water filter. Thinks like chromium and other heavy metals can be removed through reverse osmosis water filters. For a reverse osmosis water filter you will pay around $120 to $300.
