To determine the potential for groundwater contamination, vulnerability should be evaluated in different areas susceptible to contamination should be investigated. Aquifer (carbonate) karst or part of it is karst aquifer in the western region of Iran; due to the natural conditions of the region and human activities, they are susceptible to contamination by carbonate aquifer through holes devour...
Drought and overexploitation of groundwater should control the aquifer properties (e.g. storage coefficient and transmisivity). The role of stress factors is identified when the performance of aquifer hydrodynamic coefficients be studied. Since in the most aquifers, allocation and utilization management is based on the pumping test in the past, it would not be expected the optimal management. I...
Existence of heavy minerals in waters in some regions causes serious environmental pollution and affects the soil and water resources quality. Soil and waters sensitive to pollutants were investigated in this research, based on the degree of sensitivity of their parameters. The samples obtained from industrial and agricultural areas for identifying water tables at higher risk and display region...
Background Nitrate is among major anions in drinking water. Therefore, it is crucial to investigate its concentration in water resources. Modeling is a management strategy to predict the behavior of nitrate in water resources. Objective The current study aimed to predict nitrate concentration in the aquifer of Qazvin plain, using Groundwater Modeling System (GMS). Methods The GMS7.1 software ...
Groundwater in a coastal sand aquifer is enriched in arsenic as a result of historical discharges from an industrial facility on the central NSW coast. Subsequent investigations also identified arsenic in the soil within the saturated zone down-gradient of the source area. Arsenic concentrations in soil and groundwater decrease markedly along a narrow flow path towards a tidal river some 300 m ...
Background The presence of nitrate is one of the factors limiting the quality of groundwater resources, particularly in arid and semi-arid climates. Therefore, the knowledge about the distribution of nitrate in groundwater and its source has an effective role in protecting health. The study aimed to optimize an interpolation method to predict the nitrate concentration and assessment of aquifer ...
DOI 10.1007/s10040-002-0225-5 Abstract Suzhou City, located at the lower reaches of the Yangtze River in southeastern Jiangsu Province, is one of the few cities in China which suffer from severe ground settlement. A research project was carried out to investigate this problem. Geological and hydrogeological studies show that there is a multi-layered aquifer system with three distinct, soft mud ...
