Study Finds Arsenic in Drinking Water Increases Heart Disease Risk

New research highlights that even low levels of arsenic exposure can significantly raise cardiovascular disease risk, prompting calls for stricter regulations.

Research shows that long-term exposure to arsenic in drinking water, even below the federal limit of 10 µg/L, increases the risk of heart disease.
The study involved nearly 100,000 participants in California, revealing a 5-6% increased risk at arsenic levels between 1 and 5 µg/L.
Those exposed to arsenic levels between 5 and 10 µg/L faced a 20% higher risk, while exposure at or above the limit doubled the risk.
Arsenic contamination is a nationwide issue, with nearly half of U.S. drinking water wells showing levels above 1 µg/L.
Researchers urge a reevaluation of current EPA standards, suggesting that even lower arsenic levels may pose significant health risks.
