February 13, 2017 (Source: FSU) - A Florida State University researcher has drawn a link between the impact of climate change and untreated drinking water on the rate of gastrointestinal illness in children. Assistant Professor of Geography Chris Uejio has published a first-of-its-kind study, “Drinking-water treatment, climate change, and childhood gastrointestinal illness projections for northern Wisconsin (USA) communities drinking untreated groundwater,” in Hydrogeology Journal. The study explores the benefits of additional drinking water treatment compared to the risks created by climate change. “Most people may not realize this, but there are about 20 million people in the country who access drinking water that isn’t treated,” Uejio said. “These households are particularly vulnerable to rainfall events and contamination events where disease causing pathogens can get in their drinking water sources.”
