Physico-Chemical Analysis of Water Sources in Awka-urban, Anambra State

Abstract

The focus of this study was analyse the physico-chemical properties of water sources in Awka Urban, Anambra state. The water sources include bore well/hole water. It was an experimental research carried out in Awka metropolis between July 1, 2018 and October 10, 2018. The experimental research design was adopted. Five different villages in Awka were selected as sample area for the study. A total of 5 water samples from the area were collected using bottles. The bottles were washed with tap water with the aid of detergent and ethanol. The chemical parameters of the samples determined using standard method as soon as the samples got into the laboratory. HANNA Phep (model H 19) was used to determine the water PH. In the same manner, TDS/TEM meter was used to determine the water samples temperature. The electrical conductivity of the water samples was also determined using precalibrated conductivity meter model 611 in measuring the electrical conductivity. The titration method by means of EDTA solution was used to determine the total hardness of the collected water samples. The dichrometre refluction method was used to determine the chemical oxygen demand (COD) of the collected water samples. The alkali azide method was employed in the determination of the biochemical oxygen demand (BOD) of the water samples. The chlorides content of the water samples were determined using silver nitrate solution.
