Physicochemical Properties and Heavy Metal Analysis of Avalahalli Lake, Bengaluru, Karnataka, India

The present research was to determine physicochemical properties and heavy metal analysis of Avalahalli lake. Study was conducted of November 2017 to March 2018. Avalahalli lake is highly contaminated with domestic sewage, solid wastes and highly toxic compounds generated from cement factory. Water samples were collected and studied for physicochemical properties and heavy metal analysis. The samples were analyzed for pH, Total Dissolved Solids, Electrical Conductivity, Turbidity, Alkalinity, Hardness, Calcium, Magnesium, Nitrate, Phosphate, Fluoride, Sulphide, Chloride, Sulphate, Sodium, Potassium, TSS, Boron and heavy metals like Chromium, Lead, Copper, Iron, Nickel and Zinc by comparing the standard and reference range. The quality of water was extremely polluted and conservation strategies are most required.
