ABSTRACT: This study assessed the impact of landfill leachate on the quality of groundwater obtained at Agbani metropolis in Enugu state, Nigeria. Specifically, the study focused on analyzing the physiochemical and bacteriological contents of the groundwater obtained from the wells close to the dumpsites, with a view to recommending whether the water is good for human consumption. The study used a total sample of six (6) wells with borehole water as control. Thirty-one (31) parameters comprising nine (9) physical parameters, eleven (11) chemical parameters, eight (8) heavy metals, and three (3) bacteriological parameters. These parameters are; Temperature (0C), turbidity, taste, odour, colour, Electrical conductivity (EC), total solids (TS), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), pH, total acidity, total alkalinity, Chloride (Cl-), total hardness, phosphate, sulphate (SO42-), Dissolved Oxygen (DO), Nitrate (N03-), Magnesium Hardness, Calcium Hardness, Zinc (Zn), Lead (Pb), Copper (Cu), Arsenic (As), Manganese (Mn), Chromium (Cr3+), Iron (Fe), and Magnesium (Mg). The criteria behind selection of these parameters were based on the parameters being the common pollutant elements in groundwater around the dumpsites. All tests were performed as per standard methods while the water quality was compared with both Nigerian and WHO recommended standards for drinking water. Analytical techniques employed in the quantitative data analysis were descriptive statistics such as mean, standard deviation and graphical representation, as well as inferential statistics like student’s t-test with the aid of IBM-SPSS 25.0. Results uncovered that Most of these parameters indicated traceable pollution but were below the World Health Organization (WHO) and Nigerian Standard for Drinking water quality (NSDWQ) limits for consumption. Specifically, it was ascertained that most of the chemical parameters (Total Hardness, Chlorides, Phosphates, Sulphates, Magnesium, Zinc, Manganese and Chromium) showed a 100% compliance with WHO standards. However, some other constituents in the water exceeded the recommended WHO standard for drinking water; hence, the groundwater of the area is termed polluted and not fit for human consumption. Also, the study revealed that water quality in terms of bacterial account did not conform to the WHO water quality standard and Nigerian Standard for Drinking Water Quality. However, it was suggested that there is need for proper treatment of groundwater in this area before domestic use.
