The suitability of groundwater for drinking purpose with respect to BIS: 10500-1991standards is assessed through statistical analysis of the data and on the basis of seasonal variation in the quality of groundwater. The study was undertaken during 2010-2011. The samples are collected during post monsoon period from bore wells being monitored by the Andhra Pradesh Rural Water Supply and Sanitati...

An approach to assess the risk of groundwater quality degradation with regard to fixed standards. based on Disjunctive Kriging (DK) is presented. The DK allows one to evaluate the Conditional Probability (CP) of overriding a given threshold of concentration of a pollutant at a given time, and at a generic point in a considered groundwater system. The result of such investigation over the consid...

hyderabad is one of the fastest growing indian megacities which have significant impact on itsenvironment. the surface and groundwater resources are severely affected by uncontrolled expansion anddensification of the city. for the better understanding, recovery and to prevent future deterioration of thesesignificance resources, it is necessary to have knowledge of the impact of urban growth in ...

abstract guilan is a famous province in growing rice in iran. recently, due to shortage of water, farmers' desire to use groundwater in order to grow rice in northern part of iran has been increasing rapidly. the fact that rice is sensitive to water quality, caused concern about rice cultivation sustainability in the area, especially in drought years. this study was done to investigate the spat...

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...

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 ...

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...

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...

groundwater quality regarding major anions and cations in the birjand plain located in the largest desert in eastern iran was monitored in this study. fifteen boreholes were considered as sampling stations and the parameters ph, tds, ec and major anions and cations were measured in groundwater samples. the dominant groundwater types can be introduced as sodium-chloride and magnesium-sulphate. t...
