Assessment of Physico-Chemical Parameters of River Sabon Dagah, Minna, Niger State

Abstract

The study on the assessment of the physico-chemical parameters of Sabon Dagah River Minna, Niger State, was carried out from May to September, 2019 with the aim of determining the physical and chemical parameters of Sabon Dagah River and also to identify the fish that may be present in the river. Four sampling stations were selected, namely: Upstream (Station 1), before the bridge (Station 2), after the bridge (Station 3) and downstream (Station 4). The physico-chemical parameters were determined using standard methods, procedures and techniques. The results obtained showed the results of the measured parameters water tempe- rature (26.35±0.20°C to 28.33±0.08°C), pH (6.52±0.05 to 9.08±0.10), conductivity (118.0±1.32μs/ cm to 195.75±0.76 μs/cm), total alkalinity (3.65±0.25 mg/L to 25.5±0.42 mg/L), total hardness (64.5±1.18 mg/L to 34.9±2.31 mg/L), chloride (8.32±0.28 mg/L to 11.21±0.32 mg/L), calcium (6.30±0.75 mg/L to 22.15±0.65 mg/L), CO2 (0.75±0.04 mg/L to 3.41±0.31 mg/L), total dissolved solids (51.84±1.18 mg/L to 125.28±0.46). The assessment of River Sabon Dagah's water quality revealed variations among sampling stations and months. While some parameters met WHO standards, others, like dissolved oxygen and biological oxygen demand, indicated potential pollution sources such as agricultural runoff and industrial discharges. Conservation efforts and pollution control measures are vital to safeguard the river's health and freshwater resources in the region.
