An interactive map shows users where different communities draw their drinking water.
It works by zooming in on selected areas whereby clicking on a city shows descriptions of its water sources.
For example, Lansing, Mich. draws much of its water from 124 wells tapping an underground aquifer.
Fort Wayne, Ind. gets it from the St. Joseph River and the people of Parma, Ohio get theirs from Lake Erie.
