| Abstract: | Based on the groundwater chemical analyses and dynamic monitoring data, and according to the groundwater quality standard and the drinking water quality standard of China, the groundwater quality in northwest China was synthetically evaluated in this paper. The results showed that the groundwater quality in northwest China was not in a good state and that groundwater was unfit for direct usage occurs at the center of the endorheic basins in this region. Groundwater contaminants, such as TDS, total hardness, nitrate, nitrite, sulfate, chloride, fluoride, mostly spread near the cities and industrial enterprises. They often occurred as spots and lines in the region. |
