Overview

• 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.
