High-profile water contamination crises like the one in Flint, Michigan, shake confidence in US water systems. This chapter examines the links between tap water failure, reduced trust in utilities and government, and increased demand for commercial water. We show that negative experiences with basic service quality erode overall trust in government and increase demand for private alternatives. Analyses of data from three independent national surveys demonstrate that individuals who experience problems with their local water such as dirty, bad-tasting, or low-pressure water service also report lower trust in local, state, and federal government. The relationship between water service quality and trust in government persists after controlling for party identification, race, ethnicity, and socioeconomic status. We also find that tap water failure correlates with increased demand for commercial water sold from water kiosks, privately owned commercial water vendors. Taken together, these findings suggest that basic service failure erodes performative trust in government and increases demand for commercial drinking water.
