In the Eastern Niger Delta region of Nigeria, boreholes are drilled haphazardly and without coordination leading to numerous cases of abandoned wells. This unwelcome trend results from lack of technical inputs into the design, materials and effective supervision, as well as general lack of geologic and hydrogeologic knowledge of the area. These issues can be said to be responsible for the high rate of borehole failure as well as poor performance and yield in most places. In the study area, there is a huge proliferation of water business, whether for commercial purposes or for private, industrial or domestic use. It is observed that in the study area, the ease of drilling due to high water table and the large population with increasing water demand has apparently made water drilling a business for anyone. Groundwater development in the area which should have been exclusively handled by the trained professionals in the field of hydrogeology and other relevant groups, has been seriously undermined, hence there is little or no control in the area of resources development, particularly in the area of water well drilling. The geological and hydrogeological challenges, coupled with the difficult environmental terrain required highly experienced professionals. This paper therefore highlights the hydrogeologic uncertainties as well as technical realities for sustainable water supply borehole construction and maintenance. It also suggests sustainable options for borehole design, drilling, completion and development in the Eastern Niger Delta region.
