Quantifying spatio-temporal variations in heavy metal enormity of groundwaters from Ankaleshwar area
Heavy metal dispersion in groundwaters of Ankaleshwar Industrial Estate, south Gujarat displays colossal temporal variability in both degree and space. In order to facilitate the quantitative measure for site-specific variations, Normalized Difference Dispersal Index (NDDI) maps for five en ironmentally sensitive heavy metals (Ni, Zn, Cu, Mn and Pb) were generated by clutching geochemical analyses and GIS-based raster images.
