Water quality management for the Talkatora Lake, Jaipur - A case study

This paper describes the field-based research study undertaken to quantify the pollution, identify the sources of pollution and draw up a plan of acti on to restore the water quality of the Talkatora Lake located in Jaipur Cit y, capital of Rajasthan State. Laboratory analysis of water samples at diff erent time periods and a mass balance of the lake waters showed that the fi rst flush of stormwater from the adjoining residential and commercial areas was a major cause of pollution in the lake. An integrated waste management strategy to limit the pollution discharged to this lake to enable self-pur ification was recommended. The mitigation measures were partially implement ed and the results of a rapid assessment of the subsequent lake water quali ty are also reported. (C) 1999 IAWQ Published by Elsevier Science Ltd.
