Abstract: Water purification in rural Honduras is the focus of the non-profit Honduras outreach medical team rescue (Hombre). We evaluated the use of water filters and tested the microbiology and clinical efficacy of water filters. A 22 item questionnaire assessed the incidence of water, access storage, purification and gastrointestinal diseases. Samples were taken from La hicaca s domestic clay filter and paired with surveys from the same family. We calculated the number of colonies of four bacterial classifications from each sample. 65 surveys were completed. 45 (69 ) individuals used filters. 15 respondents reported diarrhea at home in the past 30 days; The incidence rate is higher in families without filters. 33 paired water samples and surveys were Avalable. Twenty-eight samples (85 ) demonstrated bacterial growth. A control sample was obtained from the local river, the principal water source; number and bacterial colony types were innumerable within 24 hours. Access to clean water, the use of filters, and other treatment methods differed within a geographically proximal region. Although the majority of the water samples failed to achieve bacterial eradication, water filters may sufficiently reduce bacterial coliform counts to levels below infectious inoculation. Clay water filters may be sustainable water treatment measures in resource poor settings.
