The paper took a critical look at the menace of groundwater contamination resulting from the linkage of leachate from dumpsites and other sources among which are Kaduna, Lokoja, Lagos and China (Carpentel,Ding, and Cheng,2012; Abdullahi,Osazuwa And Sule, 2011; Abdul- Salam, Ibrahim, and Fatoyinbo, 2011; Longe, and Balogun, 2010). The paper recommends among other things that government, its agencies and the general public should employ the services of geophysicists and waste management agencies/experts before establishing a dumpsites/landfills and put in place appropriate monitoring/supervision systems. Finally, the paper concludes by suggesting the use of Geo-electrical survey other than Seismic refraction, magnetic, chemical and microbial as a very convenient method of detecting groundwater contamination without uttering the physical and other properties of the Dumpsites. Keywords: Groundwater Contamination, Dumpsites, Waste Management. _______________________________________________________________________________________________________ 1. INTRODUCTION The prevalence use of groundwater for domestic purposes in the world and particularly in the developing countries can not be over emphasised. While the developed countries have to a large extent evolved an effective waste disposal management system, the developing nations have found it covenient to dump theirs waste indiscriminately, thereby, exposing the nation citizenry to many health hazards as a result of the concormitant contamination/pollusion of groundwater (Alimba, Bakare, and Latunji,2006). 1.1 Importance of Groundwater Abdullahi,Osazuwa, And Sule, (2011), stated that groundwater is favuoured for domestic purposes because is of high quality and requires little treatment because any present of fungi, bacteria and other biological pollutants are naturally filtered and diluted as the water perculates through the soil. Groundwater is an important source of drinking water for humankind and it contains over 90% of the fresh water resources and is an important reserve of good quality water ( Al Sabahi , Abdul, Wan, Al Nozaily, Alshaebi, 2009). The provision of potable drinking water by State Water Corporations in Nigerian cities and in many other parts of the world have not been able to meet the growing need of a large number of the world population, hence a large number of people relied very much on groundwater resource from hand-dug wells and boreholes. The situation has been further worsen by the epileptic supply of power with the consequent shortage in daily water production by the water supply scheme. 1.2 Causes of Groundwater Pollution In Nigeria, inadequate supply of pipe borne water occasioned by an increasing urban population, poor maintanace culture and the epileptic supply of power is a major concern; hence many homes have wells and boreholes as source of water for household uses. Therefore, the pressure on groundwater exploitation had increased (Gbadebo and Taiwo, 2011).The rate of urbanization in Nigeria is alarming and the major cities areas are growing at rates between 10-15% per annum (Yusuf, 2007) and thus, human activities including soil fertility remediation, indiscriminate refuse and waste disposal, and the use of septic tanks, soak-away pits and pit
