Aquitards are capable of generating and preserving large amounts of chemicals. The release of the chemicals from the aquitards poses a potential contamination risk to groundwater that may be used as a drinking water source. This work aimed to identify the contribution of hydrogeochemical processes in the aquitards to groundwater hydrochemistry in the underlying confined basal aquifer by studyin...
Landfilling, as a system to discard municipal waste, is still widely used in the tropics, often without appropriate protection against pollution of its surroundings. Leachate generation from landfills, and its chemical composition, varies widely and is significantly influenced by landfill geometry, the type and age of waste, seasonal precipitation, moisture and temperature. In the tropics, clim...
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...
Hydrogeological investigation have been carried out in Dantewada district. Groundwater samples were collected from selected locations in month of September 2013 and analyzed for major and minor cations & anions. Piper Diagram identified Ca-Mg-HCO3 dominantin water in most of the samples. The dominance of anions and cations were of the order of HCO3 > SO4 2>Cl > NO3 > PO4 2and Mg 2+ >Ca 2+ > Na ...
One hundred and nineteen karst springs, all with electrical conductivity of less than 500 gmhosfcm, discharging two carbonatic aquifers in Zagrosides of Iran are chosen and studied. The results indicate that the lithology of each unit is well reflected in the chemistry of the springs and the overall mineralogical composition of the aquifer can successfully be reconstructed from the hydroche...
Simulating adsorption of U(VI) under transient groundwater flow and hydrochemistry: Physical versus chemical nonequilibrium model" (2011). [1] Coupled intragrain diffusional mass transfer and nonlinear surface complexation processes play an important role in the transport behavior of U(VI) in contaminated aquifers. Two alternative model approaches for simulating these coupled processes were ana...
