Groundwater Quality Evaluation of Beihai, Gunangxi Beibu Gulf Economic Zone

摘要

In order to strengthen the monitoring and control of the groundwater quality, the groundwater of Hetang and Longtan water source regions in Beihai city was taken as example to evaluate the groundwater quality. PH, Total dissolved solids, Chloride, Iron, Nitrate, Ammonia-nitrogen, Cyanide, Mercury, Cadmium, Lead and so on were selected as the main factors of water quality evaluation. Single component and comprehensive evaluation methods were used to analyze the class and change trend of groundwater quality. The results showed that groundwater quality of Longtan was slightly better that of Hetang. F value of these two water source regions varied from 2.14 to 2.19 and met the classoc, which showed that the groundwater quality of Beihai City was good.
