In July, City Paper Web Editor Joshua Curry traveled to Haiti to teach photography to disadvantaged children in towns that had been ravaged by the 7.0-magnitude earthquake of January 2010. While he was there, he caught a glimpse of one of the worst aftershocks of the disaster: Clean drinking water, already in short supply, had been compromised by a massive outbreak of cholera, possibly introduced by the very people who had arrived in the country to help. Enter Water Missions International, a Christian nonprofit organization based in Charleston. Operating out of the back end of a former grocery store in West Ashley, WMI helps solve the world's worst water crises — in countries including Mexico, Malawi, Honduras, and Indonesia — with filtration and chlorination systems assembled by a team of volunteers. As of January, the cholera epidemic had infected 500,000 people and killed 7,000. WMI is still on the ground fighting back.
