Remediation of Urban Polluted Lake Water and Sediments

Abstract

Entry of contaminated soils and sediments in to the water sources from the urban runoff decreases lake water quality and increases the cost of water purification. Water pollution is inevitable issue when the surrounding activities of nearby people are not maintained proper water handling techniques with respect to preserving lake water quality along with the quantity. Sedimentation is a complex process where the eroded soil particle enters in to the water bodies through flowing water or through any of the transporting media and settles as layers on the bottom of the water bodies. Maintenance of good water quality in the lakes is always most important criteria for promoting good irrigation standards and drinking facilities to the nearby people along with other benefits like recreation, fisheries etc. but all these benefits are questionable in the current scenario as the water in the lakes are being contaminated by industrial and municipal waste disposal practices along with agricultural runoff at certain rural connected areas. Urban areas especially in India are facing severe problems with water as the availability of water reducing year by year at an alarm rate which in turn leads to increased pressure on sustainable consumption of lake water to meet the daily water demand of the city. There should be some suitable management strategies for Protecting water bodies to promote ecological balance at study area, the present study has taken up at koritapadu lake falls under the limits of guntur municipal corporation, Andhra Pradesh, earlier this lake served as major source for drinking and also for other requirements of water to the nearby people but now it became un useful as the water contamination is high and unable to consume as part of daily activities. Total eight samples were collected for both water and sediments by considering all possible corners of contamination, all he samples were analyzed by adopting standard water quality analysis procedures [7]. By keeping the above considerations this study was initiated to promote water quality for future consumption.
