The American Society of Civil Engineers estimates that 7 billion gallons of water go unaccounted for every day in the United States.

Water—a simple molecule of one oxygen and two hydrogens, with such a simple design. It’s the very structure of water that makes it strong enough to force boulders loose on a hillside. By water’s polarity, water molecules attract more water molecules and soon the long branched “polymers” are strong enough
