Abstract
Quality of groundwater used for drinking and domestic purposes near an open dumpsite was investigated. Groundwater parameters for wells GW1, GW2, GW3 and GW4 were analysed and their values were compared with World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ). Physico-chemical and bacteriological analysis were carried out to determine the quality. Parameters analysed include; Temperature, Turbidity, Total Hardness, pH, Alkalinity, Electrical Conductivity, Total Dissolved Solids, Total Suspended Solids, Total Solids, Magnesium, E-coli, Calcium, Nitrate, BOD, COD, DO, Chloride, Sulphate, Iron, Manganese and Lead. The results indicated that all parameters except turbidity, iron and lead were within the standards, all samples showed high concentration of iron and lead while GW1, GW2 and GW3 showed high Turbidity. The study concluded that groundwater situated around the dumpsite is unfit for drinking purposes. An engineered landfill located away from residential community was recommended.
