Neighborhood-level reliance on private wells is associated with lower hypertensive and ischemic heart disease mortality, an effect that is more pronounced in areas with higher percentages of Black residents.
Loop et al. (2026) conducted an observational in CVD mortality (n=3,919). Neighborhood private well use was evaluated on Hypertensive heart disease, ischemic heart disease, and stroke/cerebrovascular disease mortality. In 3,919 Alabama Census block groups, the protective association between higher private well use and CVD mortality was stronger in neighborhoods with higher percentages of Black residents.
