ABSTRACT

A series of statistical analyses including hydrochemical analysis, correlation alalysis, factor analysis, and multivariate cluster analysis were performed using the groundwater quality data in the 14 cities of Liaoning, China. The groundwater in Liaoning contains a great amount of Cl and Na. The factor analysis showed that the intrusion of the seawater to the coastal cities was the first factor to groundwater pollution, followed by the sewage of the house (second factor) and the sewage from the factories (third factor). The cluster analysis categorized all the cities in Liaoning into three groups: the cites quitely affected by the intrusion of seawater (Group 1), the cites generally affected by the seawater (Group 2), and the inland cites which are not much polluted (Group 3). The findings from this study provide valuable information to prevent the pollution of groundwater in the region.
