Concentrations and Seasonal Variations of Physicochemical Parameters in Gubi Reservoir, Bauchi, Bauchi State, Nigeria

Abstract

Physicochemical parameters of a river give fairly detailed information about the quality of the river or reservoir and also depict the suitability of the body of water for both humans that consume such water and survival of the living biota within water body. Therefore, the objective of this paper was to examine the concentrations and seasonal variations of physicochemical parameters in Gubi reservoir, Bauchi, Bauchi State, Nigeria using appropriate standard techniques. The mean values of temperature was (24±0.2⁰C), pH (7.3±0.0), turbidity (16.4±0.5NTU), TDS (98.4±1.2mg/L), EC (180.8±2.9µc/cm), DO (6.9±0.1mg/L), BOD (3.3±0.1mg/L), water hardness (60.4±1.9mg/L(CaCO₃), NO3-N (4.5±0.2mg/L) and PO4-P (1.3±0.0mg/L). The parameters were within the permissible levels except PO4-P which was lower than the permissible limits. Monthly and seasonal variations were also recorded. Physicochemical parameters should be constantly monitored in the reservoir and the state environmental protection agency should enforce appropriate measures concerning disposal of waste into the reservoir.
