Hundreds of wells that provide water to millions of residents in California's Central Valley are tainted with a chemical that some experts say is one of the most powerful cancer-causing agents in the world, NBC News reported.
Tuesday, the State of California is set to take the first step to regulate the substance — called 1,2,3, TCP — but test data compiled by an activist group show it has also been detected by utilities across the country.
Some who live in this lush farmland believe the chemical is to blame for the health problems of their family members and neighbors.
"The word that really captures all of it is 'outrage,'" Jerry Tinoco, 45, who is from the city of Arvin, told NBC News. He says at least three close family members have been diagnosed with cancer. "It's a man-made chemical, so someone is to blame."
