introduction more than 90% of drinking water in cities around the world and about 40% of the agricultural water supply from groundwater resources.,thus, groundwater quality consideration issue is inevitable . one of the most important parameter which can show the quality of drinking water is nitrate concentration. nitrate enters the groundwater and surface water through the decomposition of hum...

The hydrogeological conditions of groundwater can be examined by carefully studying the patterns of fluctuations in groundwater levels. These fluctuations are spatially and temporally influenced by many complicated factors, including rainfall, topography, land use, and hydraulic properties of soils and bedrock (i.e., aquifers). In this paper, we develop methodology based on a Bayesian logistic ...

Vulnerability assessment to delineate areas that are more susceptible to contamination from anthropogenic sources has become an important element for sensible resource management and land use planning. This contribution aims at estimating aquifer vulnerability by applying the DRASTIC model as well as utilizing sensitivity analyses to evaluate the relative importance of the model parameters for ...

  In spite of The uncontrolled exploitation of groundwater that has caused a sharp drop in water level, Agricultural, industrial and urban activities enter contaminant to various aquifers. Due to Dehgolan plain importance in water supply of industrial, drinking and agriculture, for the vulnerability assessment DRASTIC model was used. The DRASTIC model uses seven environmental parameters (Depth ...

drastic model has been used to map groundwater vulnerability to pollution in many areas. since this method is used in different places without any changes, it cannot consider the effects of pollution type and characteristics. therefore, the method needs to be calibrated and corrected for a specific aquifer and pollution. in the present research, the rates of drastic parameters have been correct...

Background and Objective: There are major mobile and non-mobile pollution sources due to human activities that can influence aquifers and reduce groundwater quality. Vulnerability assessment is an inexpensive procedure in to identify areas prone to the pollutants. Identification of these sources is essential in water resources management. Mahidasht Plain is one of the important regions of Kerma...

We present a set of data on human and chicken Toxoplasma gondii seroprevalence that was investigated and analysed in light of groundwater vulnerability information in an area endemic for waterborne toxoplasmosis in Brazil. Hydrogeological assessment was undertaken to select sites for water collection from wells for T. gondii oocyst testing and for collecting blood from free-range chickens and h...

Th ere is noticeable negative impact on soil and water quality caused by nutrient leaching, especially nitrate. Five regions in Croatia are preliminary delineated as nitrate vulnerable zones, including potentially vulnerable zones (PVZ) and vulnerable zones (VZ), one of them being Varaždin County. Agricultural land spreads on 59% of its total area. Th e survey was carried out to analyze two ava...

Thus, groundwater can be easily susceptible to infiltration from dumpsites, septic tanks and other anthropogenic activities. Approximately, one fifth of the world total freshw...
