Determination Of WQI For Stormwater : A Case Study Of River Tapi

Abstract

The River Tapi is one of the major rivers supporting agriculture and domestic usage. It also carries the discharged wastes.
Since the latter is mismanaged and over exploited the river water needs constant monitoring for sustaining the quality.
The water quality was determined through the following parameters:- pH, Turbidity, Total Alkalinity ,Total Solids , Total
Dissolved Solids ,Total Suspended Solids, Dissolved Oxygen, Chemical Oxygen Demand, Biochemical Oxygen Demand,
Chloride, Sulphate and Nitrate, Phosphate, Total Coliform and Fecal Coliform. All these parameters were considerably
affected by the discharge of Stormwater outfalls. The present study has proven that discharge Outfalls Stormwater has
heavy impact on the river. Discharge Stormwater Outfalls is relatively more polluted than the main river itself. Protection
and management of the river systems is warranted.
