How Much Water Do We Use?

From Homeland Security News Wire:

Wash. Rinse. Repeat. With every shampoo or load of laundry you may wonder, how much water did I just use?

Now multiply that thought across the nation and add other types of ways to use water, from irrigating crops to sustaining thermoelectric power generation.

The U.S. Geological Survey (USGS) has been collecting data from states on these and other water-uses since 1950. USGS says that, spanning sixty years of water-use nationally, this collective data set not only shows variations across the country and throughout time, it lays the framework for an emerging story about our evolving relationship with water.

Then and now
People and industries are changing how they use water as populations grow, technology advances, and regulations evolve. To assess these changes, the USGS developed an interactive data visualization that shows freshwater use by state every five years from 1950 to 2010.
