ABSTRACT
Pollution of rivers, had become a major problem facing our society today. This often occurs as a result of waste washed into Rivers as in the case with Nworie River in Owerri metropolis. In order to assess the water quality of Nworie River, water samples were collected at three locations namely point A (upstream) serves as control, point B (midstream) and point C(downstream). The samples were properly analyzed with focus on some physical and chemical parameters.
The result of the analysis showed that colour ranged from 5-10pt/Co, turbidity 0-1{NTU}, Water Temperature 23-26oC, pH 5.20-5.75, electrical conductivity 58.0-.77(μS), sulphate 0.061-0.076mg/Lotal hardness 20.30-52.00, total dissolved solid 38-50mgl, t, t otal suspended solid 4- 19.00, biological oxygen demand 0.4-0.7 mg/L, dissolved oxygen 5.2- 6.4mg/L, chloride 13.00-16.00mg/L, Nitrate 0.061-.0.076mg/L, phosphate 0.014-.0.053, iron, Nickel 0.10-0.99, lead 0.060-0.102 mg/L,. At the end samples were compared with Federal ministry of Environment and World Health Organization standards so as to ascertain which of this parameters are above permissible level. It was observed that some of the parameters did not exceed the recommended limit, with exception in pH which indicates that the river is acidic. Making the river very contaminated. Thus, further work on the biological profile of the needs to be done.
