Physicochemical parameters

In Nigeria, the continuous discharge of industrial wastewater with non-complaint quality parameters as stipulated by the National Environmental Standards and Regulation Enforcement Agency (NESREA) is a daunting challenge. This precarious situation has led to the continuous decline in our freshwater quality, with adverse environmental and health implications. Consequently, monitoring of wastewater discharged from industries is of utmost importance in order to check them and raise awareness, where necessary.

A seven month study was carried out between August 2020 and February 2021, to assess the physicochemical parameters of Ajiwa and Zobe reservoirs in Katsina State, Nigeria, with a view to understanding the pollution status of the water bodies. Selected water quality parameters were assessed using standard methods, these include temperature, pH, dissolved oxygen (DO), hardness, turbidity, alkalinity and ammonia-nitrogen.
