Army Corps of Engineers has built levees along the Mississippi River and its tributaries that now total 7,000 miles in length, 2,500 miles of them on the Mississippi itself. Some of these levees are 30 feet high. However, the practice of levee building is now being reassessed. Many of the artiﬁcial levees along the Mississippi River could not contain the 1993 deluge and much land was ﬂooded that had long been 42 Chapter 2 protected.

S. Geological Survey, producing 1 pound of paper uses about 100 gallons of water. Making a ton of steel requires 50,000 gallons; aluminum, 1,000,000 gallons. However, in contrast to the water used in agriculture and in the home (see below), only 10 percent of industrial water is actually consumed. Nearly all of it is used for cooling, processing, and other activities that may heat or pollute the water but do not use it up. This creates the possibility of recycling water within a factory and many industrial operations take advantage of this opportunity.
