The American Journal of Tropical Medicine and Hygiene has just published an article entitled “A Randomized Controlled Trial of the Concrete Biosand Filter and Its Impact on Diarrheal Disease in Bonao, Dominican Republic” by Christine E. Stauber, Gloria M. Ortiz, Dana P. Loomis, and Mark D. Sobsey.  The article documents a six-month trial of the BioSand Filter (BSF) in 75 households in Bonao, Dominican Republic.  The BSF is known for its potential to improve water quality and reduce diarrheal disease.  Results indicate that when compared to the 79 control households, households utilizing the BSF experienced a “significant protective effect of the BSF against waterborne diarrheal disease.”

Through the efforts of the GL-CRSP's Point of Use Household Filters for Drinking Water Improvement (POU-WID) project, BioSand Filters have also proven effective in Kenya's Njoro River watershed.  Dowload a poster and PowerPoint presentation to learn more about POU-WID and BSF successes in improving household drinking water quality and reducing incidence of diarrhea.
