“…The coastline of Tamil Nadu and Pondicherry comprises a number of cusps, spits and wave-cut platforms and several palaeo-shorelines (GSI 2006 Table 2). The results from agricultural soil corroborate with the works of Sankaran et al (2012) reported from surface soil of SIPCOT. Roadside soils showed a high degree of contamination that can be attributed to motor vehicles.…”

“…The area is marked with high salinity due to discharge from domestic and industrial effluents. Some of closed industries of the area have continuously dumped scrap and chemicals like sulphuric acid, sulphur, lime, pesticides and other raw materials, which were the chief sources of subsurface contamination (Sankaran et al 2012). Pondicherry University ground soil was taken as relatively uncontaminated control (Fig.…”

“…GPS surveying instrument Trimble Juno3 series equipped with a GPS receiver, antenna and rugged hand-held controller was used for positioning of sampling sites. The Trimble system brings precise subcentimetre control of elevation (Sankaran et al 2012). Ordinary kriging interpolations of the contaminant concentrations in soil were computed with the Arc GIS 9.2 (Zawadzki and Fabijanczyk 2013).…”

The present study was conducted along three major highways namely State Highway (SH49), National Highway (NH66 and 45A) connecting Puducherry (India) for assessing heavy metals and total petroleum hydrocarbon contamination from surface soils in close proximity at a depth of 0-15 cm into automobile repair workshops and agricultural fields located beside the highways. Contamination levels of copper, lead, zinc, manganese, cadmium and chromium were assessed in the surface sediments soil on the basis of geoaccumulation index, contamination factors and spatial variability. The results revealed that sampling sites in the proximity to automobile workshops were moderately to considerably pollution impacted as compared to soil from agricultural fields along highways suggesting a direct influence of anthropogenic activities on levels of contamination. Pearson correlation indicated a strong association of total petroleum hydrocarbon with copper, lead and zinc suggesting that the metal contaminants from roadside surface soil had emanated from a common source.

The hydrogeological setup of India represents a wide variation, from rugged Himalayan mountainous region in the north, extensive Indo-Ganga-Brahmaputra floodplain and deltaic region in the central and eastern part, aeolian-alluvial deposits in the west, vast basalt flows in the west central part, gently undulating central and southern region underlain by Precambrian crystalline, sedimentary and metamorphic, coastal deposits along the east coast etc.The research on hydrogeology has got special socioeconomic significance because India is now the largest extractor of groundwater in the world. The impact of overexploitation of the resource is surfacing in large parts of the country, in the form of lowering of water level, dwindling yield of well and deterioration in water quality.In recent years, extensive studies have been carried out in this field of geoscience. We have discussed these in different segments, after enumerating the broad hydrological framework of India. The segments are 1. Hydrogeological investigations in Indo-Ganga-Brahmaputra Plains holding one of the potential aquifer systems 2. Groundwater chemistry and contamination issues in Peninsular India 3. Urban hydrogeology 4. Groundwater modeling 5. Ground water exploration 6. Groundwater recharge and associated quality issues 7. Remote sensing and GIS applications 8. Coastal aquifers and 9. Groundwater management.It is observed that the potential groundwater reserve in the Indo-Gangetic basin and the Peninsular part of India has two serious issues: 1. Overexploitation of groundwater mainly in the western and north western parts and also in southern peninsular India in pockets and 2. Groundwater quality deterioration by anomalous concentration of arsenic, fluoride and salinity. The findings of the research will help in understanding the hydrogeological complexities in its entire gamut and also offers insight into the ways for sustainable management of groundwater resource of the country.

“…Presentation of chemical analysis in graphical forms makes the understanding of complex groundwater system simpler and quicker. Several researchers followed a series of methods to interpret and classify the groundwater chemistry in hard rock Mondal et al 2013) as well as soft rock aquifers (Subramanian 1994;Saxena et al 2003) including coastal zones in Southern India (Mondal et al 2010, Sankaran et al 2012. Using GIS technique (Senosy and Dahab 1997;Deev et al 2012;Antony Ravindran 2013), the quality of groundwater was analyzed for systematic geochemical mapping in the irrigation purpose.…”

This study mainly focused on aquifer assessment using 2-D Electrical Resistivity Imaging (ERI), hydrochemical, Geographic Information System (GIS)-based analysis and aquifer yield test for agriculture around Perumattunallur lake, Southern India. It comprises on quantifying aquifer thickness and yields with groundwater quality. The 2-D ERI technique was an attempt to study the geological structural and compare with borewell lithologs. The litho units encompass clay, calcrete weathered gneiss rock and charnockites. It shows that the resistivity of the top layer covered by clay/calcrete with kankar ranges of 1-12 Xm followed by fine sand with a resistivity range of (10-20 Xm) and calcrete mixed with gneissic rocks with a resistivity range of 20-120 Xm. The massive charnockite with a resistivity range of [200 Xm is observed in the hill ranges, present in the NE-SW direction. The hydrochemical study was attempted for the parameters (i.e., TDS, pH, Na, Mg 2? and Cl -) from bore well water samples briefly displayed by GIS-based geospatial analysis. The geochemical facies analysis of rock-water interaction study was used for the groundwater quality for agriculture.The pumping test helped to determine the aquifer yields with exact determination of the estimation of groundwater supply for agricultural use. The NW side of the wall is a high yield of water discharge from the lake. The average water yield of the study area is about 245.8 m 3 /day in summer and 310.6 m 3 /day in winter through the selected 7 bore wells. The alluvium clay with a calcrete layer occurs at the SE part and the results show as a low yield due to poor porosity. The radius influence of each well to be taken as 150 m was identified using the pumping test. The pumping test gives details about an aquifer of leaky aquifer with complex structure of gneissic rock with fracture/fault zone help for aquifer types. The results of the geophysical, hydrochemical and water yield test are used for groundwater quality and quantity for agriculture purpose and domestic use for the sustainable development of groundwater resources in the surroundings of the lake.
