Spatial Variations of Groundwater Solutes in Urban and Suburb of Jilin City

Variance analysis and variogram were used to analyze the spatial variations of eight conventional solutes, which are K++Na+, Ca2+, Mg2+, Cl-, SO42-, HCO3-, NO3-, Total hardness (TH), of 90 groundwater samples from monitoring wells that spread in the Jilin city and suburbs. It is showed that concentration distributions of groundwater solutes have significant spatial variance structure in Jilin city and suburban.. Concentration of the most groundwater solutes in urban is higher than outskirts as well as spatial variability, while the area of Jiangbei has the highest of both. Correspondingly, NO3-Cl- and SO42- have greater spatial variability than other solutes. From this research a conclusion can be safely drawed, that variance analysis and variogram are effective tools to study the spatial variability of groundwater solutes.
