However, even during these early periods of U.S. history, there were recorded instances where communities disappeared as a result of declining or contaminated water supplies. Currently, there is a water crisis in the United States that has resulted from population growth and urbanization placing pressure on fixed sources of freshwater available locally and, at times, regionally. These water access pressures have resulted in insufficient quantity and deteriorating quality of water supplies in many regions of the United States.
