Flint, Michigan is experiencing a terrifying water crisis, and other older cities are at risk if 100 year old lead pipes aren't changed soon.

Rob Curran of Fortune writes that Flint isn't the first city to experience water contamination, and it won't be the last if action isn't taken. In recent years, DC, Greenville, North Carolina, Sebring, Ohio, and Provdience, Rhode Island has seen high levels of lead in their water. If major cities such as these do not change their aging pipes, there's a higher chance of future contamination.

“Any city that fits a profile of neglect, decline, or poverty is vulnerable,” said David Zetland, a professor at Leiden University The Hague in Holland and the author of The End of Abundance: An Economic Solution To Water Scarcity.

Lead pipes are prevalent in cities that were developed in the 19th and early 20th centuries, meaning all the major metropolitan areas in the Northeast, Midwest, and California. By the latter half of the 20th century, lead was rarely used in city pipes. An official from the Dallas water utility recently told The Dallas Morning News that the North Texas city had no lead service lines.
