?Roadside springs are often used by rural communities for drinking water due to their perceived purity and taste. However, roadside springs are unregulated, and water quality at many springs is rarely monitored. This study monitored 70 roadside springs across Pennsylvania for pathogens, inorganics, and emerging contaminants. ~86% of the springs failed at least one health-based drinking water standard, potentially exposing users to disease-causing pathogens and contaminants that cannot be perceived through smell or taste.
