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.
