This study was carried out in the Ravar plain, a typical arid zone in southeastern Iran, with the objectives of evaluating hydrochemical quality of the groundwater resources and identifying the processes that modify the groundwater composition. Groundwater samples were collected from representative wells spread over the study area. Major cations and anions along with physico-chemical parameters...

The six types well networks: ...

This study was conducted to evaluate factors regulating groundwater quality in an area with agriculture as main use. Under this study twelve groundwater samples have been collected from Padra taluka, Dabhoi taluka and Savli taluka of Vadodara district. Groundwater samples were chemically analyzed for major physicochemical parameter in order to understand the different geochemical processes affe...

Leachate and groundwater samples were collected from Vendipalayam, Semur and Vairapalayam landfill sites in Erode city, Tamil Nadu, India, to study the possible impact of leachate percolation on groundwater quality. Concentrations of various physicochemical parameters including heavy metals (Cd, Cr, Cu, Fe, Ni, Pb, Fe and Zn) were determined in leachate samples and are reported. The concentrati...

Regional surveys of groundwater quality in Central Canterbury, from 1977 to the present, show widespread occurrence of nitrate contamination primarily from agricultural land use. Two reported analyses of these surveys, in 1984 and 2002, describe a general decrease of nitrate concentration with depth from the groundwater table to uncontaminated water at about 50-80 m. This high quality water is ...

Groundwater resources in Arsanjan plain provide water for agriculture, industry, and human consumption. Continued agricultural development in this area needs to additional groundwater resources for, particularly during of drought periods, and effects on the quantity and quality of ground water available. The purpose of this study is to evaluate water level changes in the aquifer of Arsanjan pla...

Water is the main source for domestic, engineering, industrial, agricultural and multipurpose uses which affects its supply and demand due to rapid rise in population. Occurrence and movement of groundwater are controlled by the degree of weathering, fracturing, the geomorphological set up and precipitation [1,2] Scarcity of potable drinking water is one of the major development issues in parts...
