due to extension of human life consumer, groundwater resources in recent decades have been increasingly intruded by contaminants. nowadays, the great challenges facing engineers and experts are groundwater protection against contamination inputs and reduction of specific pollutants of these resources. therefore, monitoring and evaluation of aquifer with a view to quantity and quality can play a...

Abstract Over the last three to four decades, several methods for assessing groundwater vulnerability anthropogenic pollution have been developed. Researchers and policymakers widely used these preventing through knowledge about particularly vulnerable areas. This systematic review presents different significant of aquifers protection resource. Previous studies mentioned that formulating a sing...

Recently recharged water (defined here as <60 years old) is generally the most vulnerable part of a groundwater resource to nonpoint-source nitrate contamination. Understanding at the appropriate scale the interactions of natural and anthropogenic controlling factors that influence nitrate occurrence in recently recharged groundwater is critical to support best management and policy decisions t...

Karst is a hydrogeological environment of importance not only for its water resources potential but also for its scenic and economic potential, thereby increasing the intensity of human impact. The uniqueness of karst in this regard stems from its high sensitivity and vulnerability to imposed pressures and its distinctive response to these pressures. Therefore, a clear definition and formulatio...

Abstract Groundwater resources in the south Darb El Arbaein are currently threatened by agricultural impact and rock water interaction associated with over exploitation. Planning of Nubian sandstone aquifer is required, especially this new invest area. It implemented GIS to establish vulnerability areas evaluate protocol plans for hydrogeological parameters soil. The TDS concentration ranged fr...

Apulia, in the absence of surface water, is one of the Italian regions which satisfy their water requirements by drawing large quantities (over 40%) of its water from underground resources. The large amounts drawn from these resources in the last few years due to increasing human activity on the territory has determined a general and inevitable reduction of the quality of the underground water ...

Objective: To determine water quality in the central zone of Texcoco aquifer, Mexico, for human use and consumption agricultural use. Methodology: The physical, chemical, biological indicators from 16 wells urban areas aquifer were determined. sampling was carried out, based on parameters definition per established current official Mexican standards. Results: According to physical concentration...
