Water Quality Assessment of Lakes in Vashi, Navi Mumbai, Maharashtra, India

The paper reveals the water quality of two major lakes in Vashi region. These lakes are excessively used for various anthropogenic activities like bathing and washing. The physiochemical quality analysis of lake water gives an idea about the health of the lake. This kind of monitoring cautions us of any degradation in the lake ecosystem that can result from the impacts of anthropogenic activities. The quality assessment of the lake makes us conscious of the lake degradation so that the corrective measures can be taken well before the impacts become irremediable. The paper concentrates on sampling and analysis of Lakes in Vashi. Seasonal analysis physical and chemical parameters of Vashi Gaon Lake and Juhu Gaon Lake were done for two consecutive years (2011-12 & 2012-13) and the results were concluded. The results revealed that there were significant seasonal variations in some physiochemical parameters and that most of the parameters exceeded the CPCB limits for surface waters. It also shows a year wise increase in the values of parameters thus indicating that the lakes require treatment. Further, remedial measures are also suggested for the restoration and conservation of the lakes
