INVESTIGATION ON GROUNDWATER, SOIL AND VEGETATION QUALITY WITH SPECIAL REFERENCE TO HEAVY METALS AROUND VRISHABHAVATHI VALLEY, BANGALORE

In this study an investigation on groundwater, soil and vegetation quality with special reference to heavy metal around Vrishabhavathi valley, Bangalore was done. Total 35 number of groundwater samples are taken from the Vrishabhavathi valley at Kengeri, Bangalore, and studied for physicochemical parameters, heavy metals like copper, chromium, nickel. 8 numbers of soil samples are taken analyzed for heavy metals (Cu, Cr, Ni) by mehlich-1 extraction method, vegetation samples (Fenugreek leafs, Amaranthus leafs, Mint leafs, Spinach leafs, Radish) which are grown in the Vrishabhavathi wastewater are analyzed for heavy metals by using AAS (Atomic Absorption Spectrophotometer) at Environmental Engineering Laboratory, BMSCE, Bangalore. Concentrations obtained for each of the samples were compared with the BIS is: 10500, 2012 for drinking water quality standard limits. All the concentrations of above analyzed samples like physicochemical parameters i.e. TDS, Conductivity, pH, Alkalinity, Calcium, Magnesium, Chloride, Nitrate, Hardness, and heavy metals i.e. Copper, Nickel, Chromium, are represented spatially  by using the specialized software called GIS (Geographic Information System) which represents the concentrations of each of the parameters spatially with respect to their sampling locations.
