I am back in Accra, Ghana. The World Health Organization and UNICEF are sponsoring a workshop here on May 6-8 to help the governments of Gambia, Ghana, Liberia and Sierra Leone increase access to safe drinking water. In these countries combined, at least 7 million people get their drinking water from sources considered unsafe and which can cause serious health problems. Delivering piped and safe water is complicated and costly and will take years to implement. In the meantime, people can treat their water at home using methods such as filtration or chlorination (assuming they aware that they need to treat their water, have access to effective products and know how to use them!). The workshop will provide a forum for discussing policies and strategies to deal with these issues.
