Understanding and overcoming water shortages
April 12, 2010

It's estimated that a billion people around the world live without reliable access to safe drinking water. This situation compounds the effects of other kinds of poverty, since time and energy expended to retrieve and purify water end up detracting from other productive activities -- and because the additional time lost to illnesses due to contaminated water magnifies and compounds the trouble. We are rarely reminded just how much is done on a daily basis to protect life and health in the United States by the work of basic tools like chlorination systems and more advanced ones like particle counters, but their behind-the-scenes work at thousands of municipal water-treatment plants all over the country save millions of hours of labor which can then be put to more productive use.
