The choices Americans make about the water that they drink reveal deeper lessons about civic life. Consumers’ spending choices reflect, in part, their identities as citizens, and citizens’ political decisions reflect their assessments of value as consumers. When government produces or regulates a basic service, the citizen-consumer’s choice between the public provider and a private, commercial firm reflects, in part, her trust in the institutions of government. Despite America’s widely available, highly reliable, high-quality tap water, the US commercial bottled water industry has exploded over the past two decades. This skyrocketing growth comes at a time of declining trust in American government. When tap water failures occur, citizen-consumers abandon utilities in favor of commercial water, and the most distrustful and politically marginalized people are most likely to opt for bottled water. Thus, distrust of government and consumption of bottled water are most pronounced among the poor and racial/ethnic minority communities. Commercial drinking water firms capitalize on this distrust with targeted marketing and growth strategies.
