133-Pollution Status of Lake Budha Pushkar of Central Aravalli near Ajmer, Rajasthan.

Abstract

In the present investigation it is focussed on the determination of water quality such as temperature, pH, free CO2 electrical conductivity, total hardness, total alkalinity, D.O., phosphate, chloride, calcium, magnesium, sodium, potassium, and nitrate of water samples from this water body. The study revealed that this lake is slightly alkaline pH (7.4-8.6), EC (0.95-1.65 mmhos/cm), free CO2 (4.4-52.6 ppm), total hardness (195-395 ppm), total alkalinity (295-750 ppm), Ca hardness (88.2-252), Mg hardness (61-169), TDS (1160-4600 ppm), Chlorides (31.24-96.0 ppm), D.O. (1.6-7.8 ppm), Sodium (13.5-64.5 ppm), Potassium (6.0-18.5 ppm), Phosphate (1.23-2.66 ppm) and Nitrate (0.85-1.32 ppm). The biological components like Oscillatoria, Microcystis, Fragillaria, Nitzschia, Spirogyra, Scenedesmus, and Lyngbya were present in this lake during the course of study. The result revealed that this lake is highly eutrophic and going for further degradation.
