Abstract
This study investigated ground water quality in five rural villages that solely depends or hand-dug wells for both domestic and commercial activities. The five villages are located in the vicinity of an irrigation farm. Water samples collected from all accessible wells in the villages using standard procedures were analyzed for a total of eleven physical, chemical and biologic parameters at University of Ilorin laboratory. These parameters are pH, Temperature, Turbidity, Nitrate, Sulphate, Phosphate, Chloride, Electrical Conductivity, Total Dissolved Solids, Bio-chemical, Oxygen Demand and Dissolved Oxygen. Laboratory results obtained were compared with both Nigerian Standard on Drinking Water Quality (2015) and World Health Organization (2014) Standard on drinking water. Finding from the research revealed that only turbidity do not fall within the acceptable standard. Although the results obtained for Temperature and Dissolved Oxygen are within the acceptable limits as recommended by NSDWQ (2015) and WHO (2014), the values of these two parameters are considered not ideal enough in some of the settlements while the high temperature in some of the settlements can easily trigger chemical reaction, the values of Dissolved Oxygen recorded in some of the settlements indicates conducive conditions for active micro organism activities. The result of comparative quality rating of all the study parameter in each of the five study settlements revealed that groundwater quality generally increase with increasing distance from the irrigation scheme.
