Encore Millions of Americans Experiencing Higher Levels of Nitrate in Drinking Water - a podcast by Jill Buck

The EPA set legal limits on nitrate levels in 1962 to prevent acute cases of methemoglobinemia, which causes an infant to suffer from oxygen deprivation in the blood after ingesting excessive nitrate. More recent studies have found correlations to additional human health risks. An Environmental Working Group (EWG) investigation found that nitrate contamination in drinking water has grown steadily worse. Data obtained under public records laws shows that between 2003 and 2017, tests detected elevated levels of nitrate in the tap water supplies of more than 4,000 community water systems in California, Illinois, Iowa, Kansas, Maryland, Nebraska, Oklahoma, Pennsylvania, Texas and Wisconsin. Those water systems supply tap water for more than 45 million Americans. Tune in as we discuss this new report with EWG Senior Economic Analyst, Anne Weir Schechinger.
