摘要
This paper aimed at investigating the hydrochemical characteristics and pollution sources of the groundwater in Liguanpu Riparian Wellhead area,on the basis of a field pollution sources investigation and a series of hydrochemical sampling campaigns,with multivariate statistical methods of cluster analysis and factor analysis.A systemic study in respect of the environment of groundwater in the area was conducted depending on these work.The results indicated the groundwater of moderate season and wet season in the area could be divided into two regions which had different hydrochemical characteristics.Zone Ⅰ principally spread along the Hun river,whose characteristics were the lower Eh values,the higher pH values,in the reducing environment,owning the serious ammonia nitrogen pollution which was principally derived from the Hun river and agricultural activities.Zone Ⅱ was mainly distributed in the northwest of the area,whose characteristics were the higher Eh values,the lower pH values,in the oxidation environment,owning the serious nitrate pollution which mainly originated from the vertical infiltration of surface pollution sources such as the daily life of residents and industrial activities.
