Legacies of past institutionalized political discrimination reverberate in present-day patterns of commercial drinking water consumption. We investigate several case studies – redlining, the Voting Rights Act implementation in North Carolina, institutionalized neglect in Appalachia, and political marginalization of Hispanics in the Southwest – to illustrate the relationship between moral distrust of government and citizen-consumer behavior. We find that areas redlined in the 1930s are more likely to host present-day water kiosks. Parts of North Carolina protected by the Voting Rights Act in 1965 have lower present-day bottled water sales than unprotected areas. Counties located within Appalachia have higher bottled water sales than counties outside of Appalachia. Water kiosks in the Southwest today are most likely to be located in predominantly Hispanic communities. Commercial water companies capitalize upon these legacies of moral distrust to market commercial water products to politically marginalized populations. “Cultural” preferences for commercial water stem from citizen-consumers’ beliefs about the competence and morality of government.
