Eighty-four percent of Sri Lankans can access improved water sources, UNICEF said in a press statement. A staggering 768 million people in the world do not have access to safe drinking water, causing hundreds of thousands of children to sicken and die each year, according to a UNICEF and WHO 2013 publication.
