Study Finds Early-Life Filtered Water Added 3.2 Months to U.S. Men's Lifespans

Researchers reported that city water filtration in early life extended older American men's lifespans by an average of 3.2 months, according to a study in the American Journal of Health Economics.
Social Security death records for men born between 1975 and 2005 were matched to each person's birth city and year against historical filtration rollouts to estimate the long-run effect of clean water.
Mid-20th-century census data also linked early filtered-water exposure to greater height, more education and higher income, suggesting childhood clean water shaped later physical and socioeconomic outcomes.
The findings are limited to men, a subset of U.S. cities and a specific historical period, so the size and timing of the benefit may not carry over to women, rural areas or other countries.

Clean Water in Childhood Increases Lifespan: Insights from the 2026 Study and Historical Data
Overview
This report highlights new research showing that early-life exposure to drinking water filtration can significantly improve human health and longevity. The study finds that access to clean water during childhood not only increases lifespan but also supports better physical and cognitive development, leading to improved life outcomes. However, many communities still lack safe water, resulting in severe health consequences worldwide. With about one in four people globally without safely managed drinking water at home, the report underscores that clean water is a fundamental factor for long-term health and well-being, making it a critical public health priority.
