Preliminary Analysis of High-Fluoride Groundwater in Aksu Prefecture, Xinjiang, China

High-fluoride groundwater has been detected in many parts of China, and some areas of Aksu Prefecture, Xinjiang Uygur Autonomous Region also suffer from the problem of high-fluoride groundwater. This article analyzed the distribution characteristics and influence factors of F- mass concentration in 22 groundwater samples collected from plain area of Aksu Prefecture. Several measures to deal with the problem of high-fluoride groundwater are proposed. The results show that: F- mass concentration in plain area of Aksu Prefecture was high in east and west and low in central area; F- mass concentration had positively correlated with the pH value ,mass concentration of Mg2- and ρ (K++Na+)/ρ (Ca2+) ratio, and negatively correlated with mass concentration of Ca2+ and HCO3- , no significant correlation with mass concentration of K++Na+, Cl-, SO42- and TDS.
