Abstract
This paper presents an assessment of the impact of uncontrolled and unscientific disposal of Solid waste on ground water in Ikere Ekiti town, Nigeria. In this study, well water quality around solid waste dumpsite sites was investigated. Ground water quality analysis was carried out on water samples collected from four wells labelled 1 to 4 close to solid waste disposal sites. Physico-chemical parameters of the water samples (such as temperature, pH, conductivity, dissolved oxygen, BOD, COD, turbidity, total dissolved solids, total suspended solids, total hardness, phosphates, sulphates, chlorides and nitrates) were measured. Results of analysis across the four samples gave a temperature range of 28 0 C - 32.0 0 C, pH 7.26 - 7.75, conductivity 393.0 - 416.0 µm/cm, BOD 4.0 - 4.5 mg/l, DO 7.5 - 9.9 mg/l, COD 4.0 - 70.0 mg/l, phosphates, sulphates, chlorides and nitrates 0.17 – 0.30 mg/l, 10.1 – 25.0 mg/l, 3.7 – 11.5 mg/l, and 0.113 - 0.22 mg/l respectively, total hardness 32.2 and 38.1 mg/l. evidences from the above measurements showed a substantial level of contamination across all samples of water. Based on these outcomes it was recommended that wells should be sited at least 30m from solid wastes dump site, Appropriate place should be located at the outskirt of the town for refuse / disposal, the wells should be treated at least three times in a year, the regulatory agency should employ a geologist on its staff list, preferably one trained in the area of hydrogeology, to assist in solid wastes site selection within the states, the use of groundwater monitoring wells should be considered in those areas where some doubts exist as to future effects of a particular solid wastes operation, the regulatory agency should not discourage novel methods of collecting and treating refuse leachates for certain installations where proper monitoring can be exercised.

Highlights
The problem of solid wastes disposal and its effect on the quality of underground water has always gained attention the world over
Developed nations boast of an organized and well engineered system of waste management which minimizes the health risk posed by waste pollution on their immediate environment (Mor et al, 2006). This is in sharp contrast to what is obtainable in developing nations like Nigeria where illiteracy, inadequate waste disposal system and awareness education, lack of capital, lack of requisite technology for environmentally friendly waste management practices and absence of political will from government and has left most places in Nigeria to rely on landfills for solid waste disposal
Another study by Amadi et al (2010) showed water samples close to the dumpsite, in Makurdi, North-central Nigeria, exhibit low pH, high content of total dissolved solids (TDS), iron (Fe), manganese (Mn), calcium (Ca), and coliform - linked with poor waste management—compared to samples farther from dumpsite
Summary
The problem of solid wastes disposal and its effect on the quality of underground water has always gained attention the world over. Studies have shown that lack of adequate monitoring by appropriate agencies has resulted in cases of reported microbial contamination of drinking water in various states in Nigeria (Adekunle et al 2007). As noted by Olowe et al (2015), reports of microbial contamination of drinking water sources, which links to a lack of public water system (potable water) and inadequate groundwater monitoring, have resulted in high rates of water-borne diseases such as cholera, typhoid fever, dysentery, and diarrhoea.
