Brief Summary
Nathan Tintle, in conjunction with others at Dordt College including Dr. Kristin Van De Griend and undergraduate student research assistants, have agreed to collaborate with Hope College to analyze the impact of different water filter deployment strategies in schools and villages on diarrhea and other medical and economic outcomes. The distribution of the water filters will begin in September 2018 to Child Hope schools in 4 different countries (Dominican Republic, Guatemala, Honduras, and Nicaragua). In order to evaluate efficacy of alternative filter deployment strategies, filters will be distributed in 4 separate treatment arms including schools, homes, simultaneous home/school and a control group
