The scientific controversy among archaeologists about the existence of paleochannels under Abydos archaeological site, Sohag, Egypt connecting Osirion (cenotaph Seti I) with Nile River has been explained in this study. This study is an attempt to address issue using integrating a near-surface geophysical approach stable isotopic geochemistry on site. Particularly, oxygen and hydrogen isotopes w...

Cadmium (Cd) groundwater contamination is a widespread problem that causes severe environmental and health concerns. Excessive concentrations of Cd, which contaminate water, have been detected in several countries, consequently attracted attention, raised significant concern. The differences Cd relate not just to the source strength but also pathways whereby transfer transport within aquifers d...

Quantum mechanical electronic structure calculations are playing an increasingly useful role in many areas of mineralogy and geochemistry. This review introduces the density functional method for such calculations, gives an overview of the density functionals developed at the University of Minnesota, and summarizes selected applications using these density functionals that are relevant to miner...

Irrigation of rice fields in Bangladesh with arsenic-contaminated groundwater transfers tens of cubic kilometers of water and thousands of tons of arsenic from aquifers to rice fields each year. Here we combine observations of infiltration patterns with measurements of porewater chemical composition from our field site in Munshiganj Bangladesh to characterize the mobility of arsenic in soils be...

Abstract Groundwater abstraction wells located in aquifers hydraulically connected with rivers or lakes will induce bank filtration if the water level aquifer is lowered below surface-water level. Many groundwater works utilize this induced infiltration to increase capacity of their wells. Unfortunately, organic-rich surface may alter aquifer’s redox geochemistry, and mobilize iron and/or manga...

Studying groundwater quality is crucial for ensuring its safety because it widely used drinking and domestic, agricultural, industrial purposes. Owing to the lack of surface water in Tabuk area Saudi Arabia, here wells are one primary sources drinking, agriculture, industry. Groundwater determined by aquifer characteristics regional geology, extensively influenced both natural anthropogenic act...
