It has been so long since the federal law regulating tap water has been updated that since 2004, more than one-fifth of the U.S. population has consumed tap water that the government classifies as toxic, but still approves for human consumption.
“People don’t understand that just because water is technically legal, it can still present health risks,” said Pankaj Parekh, director of water quality for the City of Los Angeles.
Even though more than 60,000 chemicals are used in the United States each year and most have never been tested for human safety, the Safe Water Drinking Act regulates only 91 different toxins. Many of these are regulations have not been updated since the 1980s or even since the law was first passed in 1974. The law does not take into account newer findings that certain chemicals can be more toxic in combination than separately.
