Consumption of unsafe drinking water is associated with a substantial burden of disease globally. In the US, ~1.8 million people in rural areas lack reliable access to safe drinking water. Our objective was to characterize and assess household-level water sources, water quality, and associated health outcomes in Central Appalachia. We collected survey data and water samples (tap, source, and bottled water) from consenting households in a small rural community without utility-supplied water in southwest Virginia. Water samples were analyzed for physicochemical parameters, total coliforms, , nitrate, sulfate, metals (e.g., arsenic, cadmium, lead), and 30+ enteric pathogens. Among the 69% ( = 9) of households that participated, all had piped well water, though 67% ( = 6) used bottled water as their primary drinking water source. Total coliforms were detected in water samples from 44.4% ( = 4) of homes, in one home, and enteric pathogens (, , ) in 33% ( = 3) of homes. Tap water samples from 11% ( = 1) of homes exceeded the EPA MCL for nitrate, and 33% ( = 3) exceeded the EPA SMCL for iron. Among the 19 individuals residing in study households, reported diarrhea was 25% more likely in homes with measured and/or specific pathogens (risk ratio = 1.25, cluster-robust standard error = 1.64, = 0.865). Although our sample size was small, our findings suggest that a considerable number of lower-income residents without utility-supplied water in rural areas of southwest Virginia may be exposed to microbiological and/or chemical contaminants in their water, and many, if not most, rely on bottled water as their primary source of drinking water.
