A new study by the Environmental Working Group reveals that nearly one in five Americans is exposed to drinking water with elevated nitrate levels, primarily from agricultural runoff. - 6,114 public water systems across the U.S.
have high nitrate levels, affecting 62 million people. - Nitrates are linked to colorectal cancer, thyroid disease, and birth defects, even at low concentrations.
- States with highest exposure include California, Kansas, and Texas, where CAFOs are prevalent. - Climate change worsens the problem, and proposed Farm Bill cuts could reduce conservation funding.
