Fuzzy mathematics method is used to evaluate the groundwater quality in Yang village. The groundwater quality of 18 villages belongs to V level water (GB/T14848-9 Quality standard for ground water) in the study area, where water pollution is very serious. Polluted area mainly includes the sandy soil region in northeast Yang village and east bank villages in western Beijing-Hangzhou Canal. Yinma village...
In recent years, the deterioration, eutrophication and other water pollution problems are increasingly serious in Taihu lake, which have become new constraints of regional development. Based on GIS, most applications of Taihu lake relevant research were mainly emphasized on the traditional GIS data management and analysis, which lacked three-dimensional water pollution dynamic process simulation....
According to the monitoring and analysis of chloroform in the water distribution network in a northern city of China, the variations of chloroform in the water distribution network and the major influence factors were studied. Using principle component analysis method, the prediction model which including 9 water quality indexes was established to predict the concentration of chloroform and the average...
The water resources vulnerability (WRV) is defined as the characteristics that water resources system easily suffers damage from natural factors or human activities, and it is difficult to recover to its former status once this damage happens. The quantitative assessment of the WRV is important for the scientific decision-making for the sustainable water resources exploitation and utilization. In...
This paper presents a measurement solution for heavy metals concentrations. The proposed solution can be installed in stand-alone environmental monitoring stations and can incorporate measurement units for other water quality parameters such as temperature, conductivity, salinity, pH, dissolved oxygen and turbidity. A fully-automated monitoring station based on a low-cost potentiostat unit is presented...
