The need to investigate the physical and chemical properties of groundwater quality of boreholes and type of sediments in parts of the Niger Delta region of Nigeria has been of paramount importance. This is because of the indiscriminate and uncontrollable manner by which individuals and groups of persons embark on borehole development ventures within the area. Severe water scarcity, particularly during the dry season, has compelled community dwellers to search for potable groundwater in place of not-readily available, pollution-prone and disease-stricken surface water of the area. The nature of subsurface sediments affects the portability or otherwise of groundwater; thus, this study is aimed at investigating the physico-chemical characteristics of borehole water and sediment types of the area using borehole data acquired from the zone. Results from analyses and comparison with World Health Organization (WHO) standards show reasonable conformity with finegrained to coarse-grained sediments
