EFFECT OF REFUSE DUMP ON UNDERGROUND WATER QUALITY
The major source of water in EMENE, the study area is rain, streams and well water. Waste management has been a problem in Nigeria and so many developing nations. Most organic pollutant and pollute our underground waters. In this research, three wells were reported polluted in the compound of Adedoyin school of preliminary studies, this research was carried out to know if pollution was as a result of a dump site found inside the compound. Well B was more closer to the dump site, followed by Well C and Well A. The parameters analyzed are: Turbidity, pH, electrical conductivity, Nitrate, sulphate, iron, calcium, chloride, coliform, total solids, magnesium, E-coli and Total dissolve solids. The results showed that the wells were actually polluted but most of the parameters fell within the permissible and desirable limit of WHO & NSDWQ. Coliform test exceeded the limits in all the three wells sampled with maximum value of 300per 100ml, 110per 100ml and 130 per 100ml for well A, B, C respectively. Well B showed a greater degree of pollutants within the days of sampling. Mathematical model performed showed that Well B also gave a better R value for most of the parameters. Categorization of the water sample was done uprising Canadian council of ministers of environment index (CCME) the value for the whole sample analyzed falls was 75.5 and this value is within the 65-79 which indicates that the water quality is usually protected but occasionally threatened.
