Qualitative Monitoring of Drinking Water Using Entropy Indices (Case Study: Central Aquifer of Birjand Plain)
In this research, with a new approach based on entropy theory, the regional value of sampling wells in central aquifer of Birjand Plain and the groundwater quality in terms of drinking is studied. Regarding the formation of the plain, as well as the chromium and nitrate problems of groundwater in the region, the qualitative monitoring of nitrate and chromium amounts using entropy theory has been investigated to determine the number of wells in the aquifer to accurately monitor these two parameters. The results of the trend of chromium and nitrate in the region showed an increase in the amount of nitrate and chromium in the statistical period of 2005-2014 in most of the wells studied. The highest rate of nitrate was related to well No. Rakat 11, and on the chromium values related to the wells Nos. 4 Rakat Modares. The results of the qualitative monitoring of these two parameters showed that of 19 wells in the plain, well Nos. 3 of Rakat and 4 of Modares regarding the transmission of chromium data and wells Nos. 5 Rakat and 13 of Ali Abad in terms of transfer of nitrate information in The critical situation (the lowest rank and the weakest position) and the use of their data are not accurately describing the aquifer information. Other important results obtained in this study are the location of all wells in poor and qualitative conditions in drinking water based on weighted entropy. Based on entropy of the water quality index, 63% of the total groundwater samples were rated three and 37% ranked four in terms of water quality for drinking.
