As an essential resource, water has been the object of warfare, political wrangling, and individual and corporate abuse. It has also become an object of commodification, with multinational corporations vying for water supply contracts in many countries. In Precious Commodity, Martin V. Melosi examines water resources in the United States and addresses whether access to water is an inalienable right of citizens, and if government is responsible for its distribution as a public good. Melosi provides historical background on the construction, administration, and adaptability of water supply and wastewater systems in urban America. He cites budgetary constraints and the deterioration of existing water infrastructures as factors leading many municipalities to seriously consider the privatization of their water supply. Melosi also views the role of government in the management of, development of, and legal jurisdiction over AmericaÆs rivers and waterways for hydroelectric power, flood control, irrigation, and transportation access. Looking to the future, he compares the costs and benefits of public versus private water supply, examining the global movement toward privatization.
