Abstract
This study was aimed to estimate current status of physico-chemical characteristic, heavy metals (Lead, Zinc, Copper, and Iron) content and total bacterial load of four water bodies Pichhola lake, Udaisagar lake, Bichhdi pond and Gadwa pond of Berach river system Udaipur Rajasthan. Water samples collected from these water bodies were analyzed using standard laboratory methods. Seasonal changes in physico- chemical parameters such as water temperature, pH, Total dissolved solids (TDS), Total hardness, Dissolved oxygen (DO) and Conductivity were observed for a period of one year from June 2014 to February 2015. It was found that water samples from Gadwa pond showed highest TDS, hardness and conductivity values with lowest pH values (pH 6.5). Heavy metal pollution especially zinc content was also found highest in Gadwa pond and lowest in Pichhola lake. Bichhdi pond followed by Gadwa pond in zinc content TDS, hardness and conductivity values. Total bacterial load was observed highest in Gadwa pond and lowest in Pichhola lake.
