Some water quality characteristics of the Karnafully river estuary

Abstract

The effect of domestic and factory wastes on the water was studied in the Karnafully river estuary. Turbidity of water in the disposal area increased with significant depletion in dissolved oxygen (DO) and substantial increase in biological oxygen demand (BODs). Zinc was also found in the water at the disposal site. Maximum deterioration of the water quality was observed during Summer and rainy seasons when there was excessive disposal of wastes and outfall of land washings
