In an effort to examine household drinking water contamination, observations, interviews, and physical property tests were administered in the village of Olorien in Northern Tanzania during November 2004. Observations offered insight into behavioral incidence of polluting water resources. The lack of boiling water prior to consumption and using large containers for storage led to significant results of the occurrence of E. coli. Households with lower incomes were found to boil their water less than those with high incomes, which in return led to high incidences of E. coli contamination in low-income households. It was also discovered that not a single sample contained chlorine which causes speculation that Arusha Urban Water Supply & Authority (AUWSA) is not properly treating the municipality’s water supply. Not only can original water sources not be trusted, but residents are in need of taking responsibility of caring for their supply. After the examination of one hundred houses in the village and twenty- two original water sources, it has been concluded that residents are in fact contributing to the contamination of their drinking water supply. With proper education of how to handle and store water carefully, made possible by a collaboration of extension outreach, government and NGO assistance, and individual action, residents can take control over their well-being and many lives may be saved.
