Environmental Research Laboratory, Environmental Planning and Coordination Organization,Bhopal (INDIA)
Received on : November 30, 2016
The present work was conducted in Patranalla, which is a major storm water drain of capital city of Bhopal, India. The Nalla carries the discharge of Lower Lake of Bhopal to Halali Dam, an irrigation reservoir constructed on Halali river in district Raisen. The Nalla while traversing through Bhopal city is transformed into a sewage drain as it receives waste water from number of sub-drains from the densely populated area. The water from this Nalla is also used by the local residents in rural part of Bhopal for irrigating their farm land. The study reflects a serious deterioration in water quality thereby posing a threat on water quality of the Halali Dam which is used for multipurpose activities including potable water supply and fisheries. Contamination of heavy metals in traces has also been observed in vegetable crops cultivated along the rural catchment of the Nalla.
