Pollution Level and Control Measure of River Water (Tagwai River in Minna as a Case study)

Abstract

Most water supply systems dependent on good and less polluted sources. Level pollution in Tagwai River was examined since it is the source of water supply to Minna. It is always assumed that problems may exist with a lot of agricultural and residential activities. Samples were collected from strategic points, selected namely upstream, middle stream and downstream were analysed. Both the physical, chemical and biological analysis for different parameters show that values obtained were found to be within World Health Organization standard which shows that the river is not too polluted except at the downstream where some parameters such as carbon, nitrate and COD were found 10 exceed the W.H. O. standard which indicate some pollution.
