Study On Water Quality Analysis,development And Utilization Of Several Typical Mineral Natural Spring Water At GUI Zhou Sampling Sites

Guizhou is situated in Yunnan-Guizhou Plateau,runoff trends are intricately distributed due to complex geological structures;mountains are high,torrents swift;water resources are more complex.Atmospheric precipitation is the main source of recharge water in this area,recharging of deep faults through downward infiltration.It provides material basis and hydrodynamic source for the formation of deep natural mineral water in this area.Several times development,the altered ecological environment has different effects on the source area and quality of mineral water.Therefore,further monitoring and evaluating the water quality of natural mineral water points are imperative in order to develop the original mineral water source in Guizhou.This study selected Wujiawan hot spring point,Zhongba town spring point,Shiqian county,Eastern Guizhou,and Shuitian Town Spring point in Wudang district,central Guiyang city,and Yanjiao town spring point,Liupanshui Liuzhi Special Zone,western Guizhou,and Shuicheng paper mill County spring point,the total of 5 natural mineral water points.Monitoring in accordance with National Standard of Drinking Natural Mineral Water(GB8537-2008),Organochlorine,pyrethroids,organophosphorus and polycyclic aromatic hydrocarbons in water were determined.The water quality of each spring was evaluated comprehensively,and the corresponding suggestions were made.The results of this study show that,all the springs in the five springs are colorless,transparent,turbid and tasteless,showing weak alkalinity.The main cations are sodium,calcium and magnesium,and the anions are bicarbonate and sulfate.No microbial flora in the national standard of Drinking Natural Mineral Water was detected in two mineral springs in Shiqian County.In the other three springs,individual microbial colonies were detected.The content of pollutants conforms to the national standard of Natural Mineral Water for Drinking(GB 8537-2008).No organic phosphorus,pyrethroid and other pollutants were detected in the tested samples.The water quality of Wujiawan hot spring in Shiqian County is the best according to the comprehensive score,the second is Yanjiao Town of Liupanshui Liuzhi Special Zone,the third is Paddy Field Town of Wudang District,Guiyang City,and the last is Paper Mill Town of Shuicheng County.According to the water characteristics of each typical high-quality natural mineral spring point in Guizhou province,it is suggested that the development of the water can be based on different types and combined with the current government-promoted tourism and breeding industry for comprehensive development.
