“…Various workers have studied the effect of solid wastes on the groundwater in Port Harcourt and its environs. Udom and Esu (2004) carried out a preliminary assessment of the impact of solid wastes on soil and groundwater in Port Harcourt city and it's environ and concluded that the groundwater is contaminated. Udom et al (1999) studied the Hydrogeochemistry of groundwater in part of Port Harcourt and Tai Eleme Local Government Areas and discovered that the groundwater in the Benin Formation is soft and low in dissolved constituents except pH and iron with mean values of 6.01 mg/l and 0.36 mg/l respectively.…”

ABSTRACT:The aim of this work is to investigate the effect of waste dumps on the groundwater in Choba using resistivity sounding method and laboratory water sample analysis. An ABEM SAS 1000 terrameter was used to acquire data in two locations namely; at the dumpsite and at University Demonstration Secondary School adjudged to be free from dumps which served as a control. The result of the survey interpreted by 1P12 win and offix softwares shows two characteristic curve types: -Type A curve at the dumpsite and Type H curve at the University Demonstration Secondary School. The result further indicates that the first two layers at the dumpsite has resistivities of 59.91 and 20.10 ohm.m respectively and at the Demonstration Secondary school as 173.00 and 512.00 ohm.m respectively, showing that the groundwater at the dumpsite is polluted because of the high conductivity . This was confirmed by the laboratory water sample analysis from the environ. However, fresh uncontaminated water is got below 23m deep at the two sites. Niger Delta has multi aquifer systems, therefore geophysical survey is essential to locate at least the depth to the third aquifer which hopefully will give portable drinking water free of contamination.

“…Moreover, the common hydro-geochemical features in the region are the presence of saline, brackish and freshwater system, and the occurrences of stable metal sulfides with limited mobility and carbonate. For instance, many groundwater production wells in the eastern part of the Niger Delta such as Twon-Brass, Kolo, Gbaran-Ubie, Nembe-Bassambiri,Bille, Degema, Harry's Town, Dema-Abbey (Bonny), Opobo, Gbarantoru, Kpansia, Etegwe and Swali, revealed salt water and iron contaminations at 1710.00mg/l and 1.600mg/l respectively above World Health Organization standards in the areas [10,11].…”

Groundwater is an important natural resource which varies in quantity and quality from one location to the other both in a local and regional scale. Similarly, the degree of utilization and management also varies significantly based on the quality of groundwater resource and the level of development of the area. Unsustainable management of groundwater resource is most common in the underdeveloped and developing countries where the usage is not

The geophysical electrical method was used to investigate how the refuse dump in Eneka (Rivers State, Nigeria) affects the subsurface soil and groundwater within its environs. The research was carried out applying Wenner and Schlumberger array configurations of electrical resistivity techniques to image the subsurface resistivity within the area using ABEM SAS 300 Terrameter. A total of ten locations were investigated and the measured data across the profiles were processed using RES2DINV and ArcGIS 10.4 computer iterative software. The resulting inverse resistivity model isolated three resistivity zones (anomalously low, intermediate and high resistivity). The anomalously low resistivity zone was interpreted as contaminant leachate plumes and landfill gases from the dump area was observed to have travelled to depths of 14 m below the surface and over 30 m distance eastwards from the dump site, showing the tendency of farm land and crops pollution. However, the aquifer layer in the area estimated at the depth of 40 m may not have been contaminated. The spatial trend of almost all the resistivity values measured at equidistance reveals low value for lines 3 and 4 (which are farther away from the dump site) at the beginning and high value at the end and vice versa for lines 1 and 2. At the rate at which the leachate has infiltrated the subsurface the aquifer within the area is likely to be contaminated in the future if adequate measures are not taken.
