Toxins in California Tap Water Causing Cancer

Toxins contained in California tap water could be the cause of around 15,500 cancer cases over the course of a lifetime, a shocking new study has claimed.

Researchers from the Environmental Working Group (EWG) say chemicals such as arsenic and hexavalent chromium (Chromium 6), as well as radioactive elements such as uranium and radium, have been found in their analysis of the state's drinking water.

According to EWG scientists, carcinogens and other toxic contaminants were detected in more than 2,700 California community water systems. They estimated that 7,251 cancer cases will be caused over a lifetime in California solely due to the amount of arsenic found in the water. Statewide, nearly two-thirds of drinking water systems contained at least two cancer-causing contaminants, according to the research.
