Impact of Human Management of Hand-Dug Well Facility and Its Accessories on Groundwater Quality

Hand-dug well facility is susceptible to pollution by natural and anthropogenic sources but pollution associated with human handling and management of hand-dug well facility and its accessories has been rarely discussed. A structured questionnaire was administered among 260 respondents cutting across the 5 quarters in Iwo, Osun State, Nigeria. The data collected was subjected to both descriptive and inferential analysis. Descriptive analysis showed that majority of the respondents were of female gender who relied largely on manual mode of fetching water in their respective hand-dug well facilities. Apart from this, different kinds of ropes of varying qualities were attached to their respective water fetchers, 72.69% of which are tyre-tube containers. Data factorability and its adequacy tests showed KMO value of 62.0% and its significance at P < .05, indicating that the data can be processed through Factor Analysis (FA). FA revealed that the pollution of well water attributed to human-handling of hand-dug well facility is associated with 8 variables with a total explanation of 75.55% namely; vicinity of the facility, the side wall quality of the hand-dug well, facility utilisation frequency, facility management authorities, maintenance of the associated facilities, quality of the lid, quality of water drawers and preference for the use of drawer at a time whether single or multiple. The findings suggest that stakeholders should make uptight effort to take the management of hand-dug well facility more conscientiously for sustainable human health. Further research is suggested to extend the frontiers of knowledge on pollutants associated with hand-dug water facility.
