Environmental Status Of Hosakote Lake, Bengaluru, Karnataka, India

Abstract

The present research work carried out to determine the environment status with the physiochemical property and heavy metals pollution of Hosakote Lake, Bengaluru, Karnataka, India. Study was conducted in the months of November 2017 to March 2018. Lake was highly contaminated with domestic sewage, solid wastes and highly toxic compounds generated from local small scale industries. Water samples were collected and studied for physical, chemical and heavy metal studies. The samples were analyzed and the average range of pH (7.95), Total Dissolved Solids (345.8ppm), Electrical Conductivity (831.8µs/cm), Turbidity (1.72NTU), Alkalinity (258.33mg/L), Hardness (192.57mg/L), Calcium (137.09mg/L), Magnesium (55.34mg/L), Nitrate (0.273mg/L), Phosphate (0.344mg/L), Fluoride (0.977mg/L), Sulphide (0.501mg/L), Chloride (183.27mg/L), Sulphate (0.268mg/L), Sodium (24.8mg/L), Potassium (27.2mg/L), TSS (7.37mg/L), Boron (0.396mg/L) and heavy metals were Chromium (0.0492ppm), Lead (0.1012ppm), Copper (0.0393ppm), Iron (0.5586mg/L), Nickel (0.1805ppm) and Zinc (0.0470ppm). The water quality was heavily
contaminated with many pollutants and severe conservation strategies are most essential for the sustainable development of the lake.
