Many people drink water straight from their tap, assuming it to be safe. Unfortunately, just because it’s clear and tastes normal does not mean it’s pure. Far from it, research conducted by the Environmental Working Group (EWG) revealed hundreds of contaminants coming out of the average U.S. faucet, many at levels above what may cause health risks but below the threshold of legal action.

While the Safe Drinking Water Act was put into place in 1974 to presumably keep Americans’ tap water safe, not one chemical has been added to the list of regulated chemicals in drinking water since 1996. Nneka Leiba, director of EWG’s Healthy Living Science Program, told USA Today:

EWG analyzed data from U.S. agencies and the U.S. Environmental Protection Agency (EPA) on drinking water tests conducted from 2010 to 2015. The tests came from nearly 50,000 water utilities in 50 states and tested for 500 different contaminants. In all, 267 were detected, including:2

  • 93 linked to an increased risk of cancer
  • 78 associated with brain and nervous system damage
  • 63 connected to developmental harm to children or fetuses
  • 38 that may cause fertility problems
  • 45 linked to hormonal disruption

EWG’s analysis revealed many alarming trends, like the fact that nearly 19,000 public water systems detected lead at levels above 3.8 parts per…
