Physico-chemical evaluation of wastewater in Katsina metropolis, Katsina Nigeria

Abstract

The study was designed to assess the physico-chemical parameters of wastewater at Katsina metropolis from June-August, 2015. Water samples were collected twice in a month at three (3) sampling sites designated as K/Marusa, K/Durbi and K/Sauri and was analyzed for surface water temperature, pH, dissolved oxygen (DO), biochemical oxygen demand (BOD) and turbidity. These parameters were compared with their sampling sites in which a significant difference was observed (P<0.05). The water is well oxygenated and alkaline in all locations (7.7,7.9 and 7.67), temperature were relatively high (26̊C,25.7̊C and 25.8̊C), DO mean values were 4.6, 3.9 and 4.8 while BOD were 2.6, 2.53 and 2.53. Turbidity values were 11.5, 15.8 and 11.2. Therefore, measure should be put in place to regulate improper refuse disposal into the wastewater and a possible creation of wastewater treatment plant so as to avoid adverse conditions.
