This study investigates the impact of municipal waste on the physicochemical parameters of Epe Lagoon. Three stations were chosen where a lot of human activities take place. The samples were collected from surface water at 10cm depth for 12 consecutive months in duplicates between August 2014 – August 2015. pH, dissolve oxygen, conductivity, total dissolve solids, salinity, temperature, turbidity, dissolved oxygen and the biological oxygen demand were measured. The pH measurement was highest in March with mean value of 7.9±0.17, a rainning month and lowest in October, a dry month with mean value of 6.1±1.21 The mean dissolved oxygen value was 7.17±0.67 mg/l. The annual mean salinity value was 0.08 ppt. The water turbidity was highest in March with mean value of 68.3±3.15 mg/l and lowest in the month of June with mean value of 47 ±1.21 mg/l. The mean nitrate value was 1.31±0.07 ppm. The mean value of alkalinity was 58.34±0.67 mg/l and that of phosphate was 7.52±0.67 mg/l. Conductivity mean values ranged from 76.94 ±5.35 uhoms/cm-1 in the month of November to the highest in the month of June with a value of 94.87 ±1.39 uhoms/cm-1. In this study BOD mean value was 1.84±0.67 mg/l . Regulatory bodies should spring into action to control the dumping of munincipal waste along the course of the lagoon so as to prevent the extinction of aquatic life in the water boody.
