The continental U.S. experiences small earthquakes every day. But over the past few years, their numbers have been increasing. Geoscientists say the new epidemic of quakes is related to industrial wastewater being pumped into underground storage wells.

Half of Germany's 1,300 brewers have their own wells, and say the pure water is the essence of their famous beers. And if there's one thing Germans take seriously, it's beer.
