Assessment of surface and groundwater water quality at Regional scale
This study investigates the natural and anthropogenic processes that influence the chemistry of surface and groundwater within Laoshan District using multivariate statistical techniques. A total of 3612 surface and groundwater samples were collected between 2003 and 2007, from 19 sites and analysed for their physico-chemical constituents. The chemical data set generated were subjected to Principal Component Analysis (PCA)/Factor Analysis (FA). PCA is a procedure for reducing data redundancy, while FA establishes the general relationship among variables. The results indicate three dominant processes or factors for surface water that explained 80.51％ of the variance in the data set. In groundwater, the factors account for 80.93％ of the total variance. The multiple natural and anthropogenic sources indicated by this study suggest proper measures to surface water and groundwater resource monitor and management.
