PHYSICOCHEMICAL AND HEAVY METAL EVALUATION OF DRINKING WATER FROM VARIOUS SOURCES IN ESA-OKE COMMUNITY IN OBOKUN LOCAL GOVERNMENT, OSUN STATE, NIGERIA.

Abstract

Abstract
Water is essential to life and it is most abundant in nature. All living organisms including man and
animals need water for survival and growth, hence the quality of drinking water is of great
importance to Man because of water-related diseases such as dysentery, diarrhoea, etc. This study is
aimed at evaluating the quality of drinking water available to students and indigents of Esa-Oke.
Fourteen water samples were collected from different sources in esa-oke, physiochemical
properties, and heavy metals determination were carried out on the water samples using standard
methods. The test includes organoleptic tests such as odour, taste, and colour. Physiochemical --
parameters such as conductivity (EC), turbidity, ORP, TDS, NO , Cl , pH, etc. Zinc and Manganese
3
were determined for heavy metals. The result shows that the majority of the water samples complied
with the W.H.O standard and hence they are safe for human consumption, the Mn and Zn found in the
water samples are within the acceptable limits of WHO. This study has confirmed that the majority of
the sources of drinking water in Esa-Oke are safe for drinking and free from toxic heavy metal
