Abstract

The aim of current study was to evaluate the status of Taudaha lake water with respect to different physico-chemical parameters (pH, electrical conductivity, dissolved oxygen, free CO2, total dissolved solids (TDS), total suspended solids (TSS), total solids (TS), total alkalinity, total hardness, chloride, nitrate, sulphate, phosphate, sodium, calcium, magnesium, lead, cadmium, copper and zinc) in monsoon season 2012. Results reveal that almost all the physico-chemical parameters including the elemental investigation of the lake water have values within the range of the maximum permissible levels for drinking water. The results were compared with WHO water quality guidelines as well as with literature values reported for global lake water.
