Cancer-causing contaminants may be in your drinking water, according to a new study published in the journal Heliyon. Scientists at the Environmental Working Group (EWG) analyzed pollutants in tap water from 2010 to 2017. They found 22 carcinogenic contaminants — including arsenic, disinfection byproducts, and radioactive contaminants, such as uranium and radium — in drinking water nationwide, which researchers estimate could, over the course of an average lifetime (about 70 years), lead to 100,000 cases of cancer. In the study, EWG scientists calculated the cumulative health effects of these carcinogens in more than 48,000 community water systems in the U.S. (not including the 13.5 million Americans who rely on private wells for drinking water). The World Health Organization places processed meat in the same category as tobacco smoking and asbestos when it comes to carcinogenicity. Although the three groups are not considered equally dangerous, processed meat has been proven to cause colorectal cancer. Studies show that “every 50 gram portion of processed meat eaten daily increases the risk of colorectal cancer by about 18 [percent],” the U.N. agency notes. Rese...
