Acceptance and Impact of Point-of-Use Water Filtration Systems in Rural Guatemala.
Infants and children in developing countries bear the burden of diarrheal disease. Diarrheal disease is linked to unsafe drinking water and can result in serious long-term consequences, such as impaired immune function and brain growth. There is evidence that point-of-use water filtration systems reduce the prevalence of diarrhea in developing countries. In the summer of 2014, following community forums and interactive workshops, water filters were distributed to 71 households in a rural Maya community in Guatemala. The purpose of this study was to evaluate the uptake of tabletop water filtration systems to reduce diarrheal diseases.



A descriptive correlational study was used that employed community partnership and empowerment strategies. One year postintervention, in the summer of 2015, a bilingual, interdisciplinary research team conducted a house-to-house survey with families who received water filters.



Survey data were gathered from the head of household on family demographics, current family health, water filter usage, and type of flooring in the home. Interviews were conducted in Spanish and in partnership with a village leader. Each family received a food package of household staples for their participation. Descriptive statistics were calculated for all responses. Fisher's exact test and odds ratios were used to determine relationships between variables.



Seventy-nine percent (n = 56) of the 71 households that received a water filter in 2014 participated in the study. The majority of families (71.4%; n = 40) were using the water filters and 16 families (28.6%) had broken water filters. Of the families with working water filters, 15% reported diarrhea, while 31% of families with a broken water filter reported diarrhea. Only 55.4% of the homes had concrete flooring. More households with dirt flooring and broken water filters reported a current case of diarrhea. A record review of attendees at an outreach clinic in this village noted a decrease in intestinal infections from 2014 (53%) to 2015 (32%).



A trend suggests that water filter usage was both practically and clinically significant in reducing the incidence of diarrheal disease in this sample. Some homes did not have flat surfaces for water filter storage. Housing conditions should be taken into consideration for future diarrheal disease prevention initiatives.



Point-of-use water filters using a community-university partnership can reduce diarrheal disease in rural regions of Guatemala.
