Abstract In this study, an attempt was made to understand the hydrogeochemical processes controlling water resources (surface and groundwater) evolution in El Fayoum depression, Egypt. Hydrochemical, inverse geochemical modeling integrated with environmental isotopes applied. Forty-three surface groundwater samples were collected analyzed for major chemistry (cations, anions) stable (δ 18 O, δD...

Abstract Groundwater is a vital natural resource in the Kathua region of Union Territory Jammu and Kashmir, Northern India, where it used for domestic, irrigation, industrial purposes. The main purpose this study was to assess hydrochemistry groundwater determine its suitability drinking, uses region. In study, 75 samples were collected analyzed physicochemical parameters such as electrical con...

This paper presents results of hydro-chemical processes controlling groundwater chemical composition, using an integrated application of hierarchical cluster analysis and factor analysis of a major ion data set of groundwater from Mighan playa aquifer. Cluster analysis classified samples into four clusters(A, B, C and D) according to their dominant chemical composition: cluster A (dominant comp...

For radioactive waste disposal, it is important that local groundwater flow slow as the main transport medium for nuclides in geological formations. When very slow, diffusion dominant mechanism (diffusion-dominant domain). Key pieces of evidence indicating a diffusion-dominant domain are separation components and fractionation isotopes by diffusion. To prove this, necessary to investigate diffe...

Salinization of groundwater in semiarid regions, as a limiting factor of use, has a strategic importance. In this study, the sources of salinity, chemistry and Quality of groundwater in Robat – Khorramabad plain have been identified using geochemical methods. Using data analysis, the concentration of cations and anions are recognized as Ca2+>Na+ >Mg2+>K+ and HCO3-> Cl-> SO42+> NO3-> F-. High co...

With a mean precipitation rate, much lower than that of the world, Iran is among the countries that face severe water challenges. The present study has dealt with the evaluation of hydrochemistry of Faryab spring water in Hormozgan Province, Iran. Four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, pH, and s...

One of the important purposes of hydrology is to ensure water supply in accordance with the quality criteria for agricultural, industrial, and drinking water uses. The groundwater is the main source of water supply in arid and semi-arid regions. This study was conducted to evaluate factors regulating groundwater quality in Rafsanjan plain. A total of 1040 groundwater samples randomly were colle...
