mapping of groundwater nitrate can be useful in management of groundwater resources. the objectives of this study were to analyze the spatial variability of nitrate and to map its contamination in the lordegan aquifer and to evaluate the variations in nitrate variability and mapping during a year. then 32 wells were sampled four times during 2010. seasonal nitrate concentrations remained consta...
Since naturally occurring methane and saline groundwater are nearly ubiquitous inmany sedimentary basins, delineating the effects of anthropogenic contamination sources is a major challenge for evaluating the impact of unconventional shale gas development on water quality. This study investigates the geochemical variations of groundwater and surface water before, during, and after hydraulic fra...
Combined resistivity and IP investigation is a powerful tool for mapping contaminant leakage as well as delineating the extent of contaminated ground and buried waste. Resistivity investigation is well established for detection and mapping of contaminated ground and groundwater. Low resistive zones around contaminated industrial sites and landfills correlate with high ion contents in groundwate...
The objective of this study was to evaluate seasonal fluctuations in groundwater quality, determine the effects different stressors on resource, and recognize potential pollution sources a coastal region southern Vietnam. Eleven samples collected Ben Tre province during dry wet seasons were then analyzed for sixteen parameters, including pH, total dissolved solids (TDS), salinity, hardness (TH)...
