This study investigates the impact of anthropogenic activities on groundwater quality; this was achieved by determining the concentration of potential anthropogenic contaminant indicator parameters such as nitrate, chloride, phosphate, and sulphate in the groundwater samples of the study area. A total of 30groundwater samples,15 each from the northern and southern partsof Maiduguri where obtained across a period of 2 months. Results ofthe groundwater analysesshowed that nitrate (NO3-) has mean concentration of 13.7mg/l in the northern part (site A), and 15.53 mg/l in the southern part (site B).Chloride (Cl-)has a mean concentration of 10.62 and 13.33 mg/l respectively in sites A and B. Sulphate (SO4-) has mean concentration of 3.52 mg/l in site A and 1.46 mg/l in site B. Lastly,phosphate (PO4-) has mean concentration of 1.39 and 1.52 mg/l in sites A and B respectively. The Mean concentrations were tested for their significant difference (p <0.05) across the boreholes of the two sites.Water quality results indicate that the impact of anthropogenic activities in the study area is low to moderate currently. The outcome of this paper will be useful in planning for sustainable groundwater management strategy.
