The present study is focused on seasonal variation in groundwater quality, hydrochemistry, and associated human health risk in the Shivganga river basin, Western Maharashtra, India, to promote sustainable development of groundwater resources of this semi-arid region. The qualitative geochemical analysis, contamination levels, and human health risk...

Groundwater occurrence in hard rock basaltic terrains is restricted to weathered and fractured zones and pockets wherein slow movement of groundwater, prolonged rock-water interactions and higher residence time alter the natural chemistry of groundwater raising water quality issues. The qualitative geochemical analysis, contamination levels and hum...

Nitrate pollution from various sources is one of the foremost problems worldwide. In Indian scenario the most of the groundwaters are at serious risk of pollution due to nitrate inputs from various agricultural, industrial and urban sources. In an attempt to evaluate the extent of nitrate contamination precincts, besides their possible sources, 37...

Geospatial techniques have become one of the leading tools in the field of natural sciences for assessment, monitoring and management of natural resources, particularly in groundwater research. The paper discusses the demarcation and assessment of groundwater potential zones using geospatial techniques in the Deccan Volcanic Province of Maharashtra...

Vertical electrical resistivity soundings (VES) were carried out over four major dykes of Nandurbar district in the northern Deccan Volcanic Province (DVP) of Maharashtra to investigate the subsurface geological conditions, with an aim of identifying zones with groundwater resource potential. Dykes can act as pathways or barrier to the groundwater...

The ever increasing demand for freshwater and overexploitation of existing reserves has necessitated the search for new resources, particularly in hard-rock terrains where groundwater is a vital and sole source for drinking and other activities. A fast and cost effective way of groundwater exploration is the study and analysis of remote sensing dat...

The seasonal behavior of environmentally sensitive polymetallic contaminants in groundwaters from Ankaleshwar industrial estate (AIE) India was studied. The potentially toxic elements (Co, Cr, Cu, Mn, Fe, Mo and Ni) demonstrated accentuated enrichment signatures during post-monsoon, besides colossal spatial variability on temporal scale. GIS-based...

The Earth's land cover characteristics and its use are key variables in global change. The society today is already in the mainstream of another revolution - the information revolution. This brings enormous changes to life and living, providing new approaches: how to advance the frontiers of previous revolutions particularly those of earth resource...

Heavy metals in the groundwater from Ankaleshwar industrial estate (AIE), south Gujarat, exhibit widespread and consistent seasonal augmentation. Hyper-accumulation zones for seven potentially ecotoxic heavy metals (Co, Cr, Cu, Mn, Fe, Mo and Ni) were delineated using two season geochemical data and GIS based raster images. These zones, with respec...

Leachate produced by municipal solid waste dumping site near the metropolitan city of Pune, India was examined for its pollution potential and impact on surrounding shallow basaltic aquifers. Twenty-eight physico-chemical parameters during post- and pre-monsoon seasons (Nov 2006 and May 2007) were determined to assess the seasonal variation in the...

In modern civilization, numerous anthropogenic activities release a variety of pollutants into the environment and with anomalous enrichment of heavy metals it causes surface and subsurface contamination. The aquatic sediments provide pertinent tools for the quality assessment of urban and industrial environments in large cities. The present study...

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 environmentally sensitive heavy metals (Ni, Zn, Cu, Mn and Pb...

Analyses of 72 samples from Upper Panjhara basin in the northern part of Deccan Plateau, India, indicate that geochemical incongruity of groundwater is largely a function of mineral composition of the basaltic lithology. Higher proportion of alkaline earth elements to total cations and HCO3>Cl + SO4 reflect weathering of primary silicates as chief...

In an attempt to delineate heavy metal contamination precincts and to evaluate the extent and degree of toxic levels, besides their possible sources, 38 water samples from Ankaleshwar Industrial Estate, south Gujarat, India were analyzed. By clutching geochemical analyses and GIS-based colour composites areas depicting anomalously high concentratio...
