Groundwater vulnerability is basement of evaluating risk of groundwater contamination and groundwater vulnerability assessment is one of management methods for preserving the quality of groundwater. Based on DRASTIC model and GIS techniques, shallow groundwater vulnerability assessment was carried out in Xiangcheng City, China. The results indicate that the studied area can be divided into three zone:...
The study area is physiogeographically located along the western flank of Songnen Plain, and hydrogeochemically distinguished as a basin with groundwater generally flowing easterly. A total of 196 groundwater samples were collected to not only cover the whole study area but also to extend in different aquifers that include Quaternary phreatic groundwater, Quaternary Baitushan Formation confined groundwater...
Groundwater plays more and more important role in people's daily lives and social development in the study area for lack of surface water resources. So works of groundwater quality monitoring and assessment have great meaning to protect the public health. The geographic information system (GIS), as an analysis tool and visualization platform, is used to support data used, monitoring and groundwater...
Groundwater constitutes the largest single source of fresh water in many parts of the world and provides a risk buffer to sustain critical water demands during cyclic and prolonged dry periods, especially in semi-arid and arid regions. Intensification of agriculture, increases in land area devoted to arable crops, intensification of animal husbandry, and a move away from arable rotations toward monoculture...
