![]() Dumpsite could be classified as landfills and open dumpsites. In Nigeria and most other developing countries, solid wastes are disposed or dumped in barren lands and many are not properly managed if managed at all. It is worthy of note that when dumpsites are not covered (open) they attract flies, insects and other animals that would cause diseases or other public health problems to people living around such waste management facilities most especially scavengers (Dong et al. The presence of dumpsite in an area most times adversely affects the general condition of environment and residents of the area. ![]() These, most times lead to pollution and contamination of the environment. The review also showed that age of the dumps and the migration distance of the leachate are important factors that require consideration because of the closer the dumpsite the higher the concentration of the contaminant.ĭumpsite is a widespread land meant or designed for deposition of waste and unwanted materials from household, institutions, industry or environment and is generally open or covered with soil layer with or without liner at the bottom. ![]() As such, consumption of such water is dangerous to human health. The results obtained with the application of physiochemical analyses of leachate inferred various degrees of severe contamination of groundwater due to organics, salts and heavy metals. The result was complimented by other geophysical techniques applied. The results obtained using the resistivity methods showed zones or area with low resistivity as leachate plume and fractured subsurface as contaminant pathways. The geophysical methods adopted by the studies under review are Electrical Resistivity, Electromagnetic Induction using Very-Low-Frequency and Seismic Refraction methods. This study is therefore designed to review studies on the impact of groundwater contamination due to dumpsites using geophysical and physiochemical methods. Dump/landfill is a major source of contamination of groundwater. ![]() Dumpsite is a widespread land meant or designed for deposition of waste and unwanted materials from household, institutions, industries or the environment and is generally open or covered with soil layer with or without liner at the bottom. ![]()
