Causes of the global water crisis and 12 companies trying to solve it

Mar 27, 2017

It’s World Water Day. Time to wake up and take shorter showers. That is, if we’re fortunate enough to have them. Water scarcity and pollution are persistent global problems. According to End Water Poverty, some 663 million people around the world have absolutely no reliable access to clean, safe water year-round. And two-thirds of the world population faces water scarcity for at least one month every year.

In the wealthy US, we’re facing a different kind of water crisis largely of our own making. In 2016 only 9 states reported safe lead levels in their schools’ water supply. Lead and copper contamination can come from irresponsible industry, aging pipes, ineffectual water treatment plants and too little investment in our public water infrastructure.

Droughts and natural disasters can cut off access to potable and sanitary water anywhere in the world, too. Haiti is known as a “pipeless nation,” still recovering from 2010’s catastrophic earthquake and consequent natural disasters. In Haiti, only one-quarter of residents have access to toilets, according to the World Bank. And it’s hard to believe it, but giant freshwater sources in North America like Lake Mead in Arizona or the Colorado River may not be able to keep pumping to residents’ homes and businesses much longer thanks to drought and pollution.
