The Healthiest Communities rankings from U.S. News & World Report are just out. They show how nearly 3,000 U.S. counties perform in 84 metrics across 10 health and health-related categories. Teton County scored high overall but was deficient in one very important category: providing safe drinking water to its residents. The report found that 29% of our population is served by drinking water systems that violate Environmental Protection Agency standards. County-level data were collected from well-recognized and validated sources, including the Centers for Disease Control and Prevention, the Institute for Health Metrics and Evaluation, the U.S. Census Bureau, the Centers for Medicare and Medicaid Services and the EPA.
