“…Chourasia and Tellam (1992) have reported that groundwater of irrigated areas have higher ionic concentration as compared to non-irrigated areas in hard rock terrain of central India. Many studies have found that the deterioration of groundwater quality is also due to over withdrawal (Kamra, et al 2002;Singh, et al 2002;Negrel, et al 2007) resulting in the higher salinity, fluoride, nitrate, iron and other heavy metals in groundwater. Further, extensive application of pesticides and fertilizers in agricultural fields, inadequate sewage treatment system (Gautam, et al 2013), and mixing of non-treated industrial and municipal effluents with groundwater (Wen, et al 2005;Rao, et al 1997;Vasanthavigar, et al 2012), decline groundwater quality.…”

The chemical and isotopic compositions of river and groundwater reflect the different natural processes that provide chemical elements to the dissolved load, i.e. mainly the weathering of rocks and soils, atmospheric inputs and anthropogenic disturbances.This study reports on the geochemistry of surface-and groundwater along a part of the Subarnarekha River system (north-eastern India) collected during monsoon and dry season, during a monitoring program aimed at evaluating impacts of mining and metallurgy on the river system.The aquifer is of fracture type and the seasonal behaviour, groundwater flow conditions and pollutant transfer were observed through a network of 69 wells with typical depths of 50 meters.Geochemical observations, including major cations and anions, trace element concentrations and isotopic tracing (stable isotopes of the water molecule, strontium isotopes) come to conclusions on the origin and the relationships between the surface-and groundwater in the studied catchment.A large range of salinities is observed in surface-and groundwater, both for dry or wet periods.Surface water samples plot within the field HCO 3 -Ca during both water stages. Most groundwater samples plot within the field of Ca-SO 4 water type and HCO 3 -Ca water type. This reflects the high Ca input in groundwater, other than weathering. Such inputs could be related to (i) carbonate amendments used in agricultural practices and (ii) residues from ore processing.

The inversion method of pumped concentration can be used as an alternative or complementary method to the conventional methods for groundwater pollution evaluation and quantification. This method is useful even when the monitoring wells are few and also when the contamination source is unknown. In a homogeneous-isotropic case, with radially dominated groundwater flow field, this method of inversion can be performed analytically. However, in many cases, the real aquifer systems are heterogeneous. A novel volume-based inverse model (VINMOD) is developed for numerical inversion of pumped concentration under heterogeneous conditions. VINMOD helps us to determine the mean concentration and mass flow rate of an "undisturbed" contaminant plume at a predefined imaginary control plane (ICP). Model verification and preliminary tests are presented using a hypothetical single-layer aquifer. It is noticed that VINMOD is highly sensitive to the groundwater flow velocity and the well capture zone geometry, which in fact influences the determination of total mass flow rate of a pollutant in the groundwater.
