Sixteen (16) groundwater wells within the Yenegoa metropolis were investigated in order to determine the groundwater flow direction. Local groundwater flow directions for selected sections of the area were first determined manually by triangulation and subsequently, a water table contour map of the entire study area was generated with respect to the variation in static water level from which the major and minor flow directions were delineated. The result shows that groundwater flow direction is predominantly towards the south-western parts of the city with the main forces affecting groundwater movement being gravity and external pressure due to pumping. The flow pattern in the aquifer system therefore suggests that the southern regions of the study area are susceptible to groundwater contamination that may arise from sections with higher hydraulic head. It is therefore recommended that municipal water wells and boreholes for domestic supply should be sited in the northern part of the study area while the location of dumpsites and sanitary landfills should be confined to the South-western regions.
