Abstract :
The purpose of this study was to investigate the effects of rainfall on the chemical quality of drinking water sources in northern Fars Province cities and on the factors EC, PH, TDS, F, NO3 in alluvial and limestone formations and in the period from 2011 to 2016 years. Finding an answer to the question of whether rainfall can significantly affect the chemical quality of drinking water sources in the cities of Abadeh, Bavanat, Eqlid, Safashahr, Pasargad, Marvdasht and Zarghan and on the factors EC, PH, TDS, F, NO3 in formations And alluvial and limestone formation in the years 90 to 95? In this study, 208 wells were mentioned in cities with 96 alluvial loops and 112 wells with calcareous formations. According to Pearson correlation coefficient and p-pain results, the results showed that precipitation on changes in EC, PH, TDS NO3 is effective. In general and cumulative analysis of this factor, it has been shown that the effect of rainfall on changes in TDS, NO3 EC is significant and its relation is direct, and it is reversible on changes in pH. Also, the effect of rainfall on changes in F level is not significant, and these changes are more significant in karst and lime formations, meaning that the wells with Karst Formation with changing precipitation rates are more likely to change EC, PH, TDS NO3 Are.
