Open Access Theses & Dissertations
Water-borne disease and its symptoms, such as stomach cramps and diarrhea, are a serious concern in areas that are not connected to a public water system. To investigate the impacts of not being connected to a community water system, I surveyed households in El Paso County colonias that were not connected to a community water system (household n = 75, individual n= 293) and households that were connected to a community water system (household n = 75, individual n= 320). I conducted 150 door-to-door surveys and tested water samples from each household for free residual chlorine level, turbidity level, presence …
