Abstract
Regardless of being essential for human survival, access to potable water is still a problem in many
rural African communities with increasing exposure to waterborne illnesses. This study aimed at
establishing accessible quality water sources in 5 drinking water sources in rural southern
Tanzania. The water quality index (WQI) and water poverty index (WPI) were utilized to grade
and measure the water quality and water stress respectively. The 26 households participated in a
socioeconomic survey to gauge the water accessibility in relation to four WPI factors viz.,
preference, accessibility (distance), quality, and seasonal availability. Results from the WPI
computed data revealed that all the investigated water sources possessed poor quality with 222.5
and 112 for surface water and shallow wells (>50 excellent, <300 unsuitable). The WPI scores for
shallow wells were safer than surface water at 45.7 as contrasted to 33.8 for surface water (0-
poorest levels, 100-best levels). This study concluded that, in this area, shallow wells have more
secure water in terms of quality and accessibility. Health data from Milola ward showed high
occurrences of water borne diseases. This study recommends urgent water treatment intervention
by the responsible stakeholders to avail clean, reliable, and accessible drinking water for vulnerable
communities.
