Abstract

The Global Positioning System (G.P.S) was used to measure the longitudes, latitudes and elevations above mean sea level at 11 locations evenly spread within Ndokwa-East Local Government Area of Delta State. The water table contour map of the study area revealed that groundwater flow direction is moderately toward the south (Aboh) and extensively towards the North-Western parts of the Region (Beneku and Ashaka). Based on the flow pattern of the aquifer system in Ndokwa-East Local Government Area, more effort should be made towards entrenching eco-friendly practices in the Eastern Regions of Okpai-Oluchi and the West Central Regions of Igbuku in order to minimize the contamination of groundwater supply to the other regions especially the North-Western zone. The research paints a clear picture of the flow system within the study area, thereby creating awareness on the possible areas that could be adversely affected in the event of groundwater contamination, it also recommend that wells and boreholes for rural and urban water supply should be sited in the South-western through the central onto the eastern regions and not within the North-Western parts of Ndokwa-East local government area.

Key words: Ndokwa east, groundwater, flow direction, elevation, water table and contamination.
