Evaluation of Aqueduct Water Quality Using Chemistry Program for Different Uses in Nain

Water on the one hand, deals with the health of people, and on the other hand, promotes economic prosperity. One of the important and determining factors in different uses of water is its chemical quality, and to manage these resources, it is necessary to obtain scientific sttudies and control them with full knowledge of groundwater systems, and chemical analysis of these waters is a suitable tool for quality assessment and water resource management. In this study, the data required to investigate the chemical quality of water in 17 aqueducts south of Nain in 2012, was abtained from the Regional Water Organization. Chemistry program was used to perform chemical quality analysis of water. After the studies and drawing the Schuler, Wilcox and Piper diagrams, the quality of the aqueducts was determined for drinking, agriculture and industry purposes. According to the Schuler diagrams, the aqueducts in question are no limited for drinking. Regarding water quality for agricultural uses (Wilcox chart), 6 aqueducts out of 17 aqueducts studied are unsuitable for agricultural use (very salty) and the rest of the aqueducts, are some suitable and some can be used for agriculture, and according to RSC of a total of 17 aqueducts, all in the appropriate, only the Feyzabad and Jamakan aqueducts are possible in the category. Regarding the industry, most of the aqueducts are part of the sedimentation group and only two aqueducts of Heydar Abad and Arand are in the corrosive category. In the south of Naein City, according to the results abtained to avoid irreparable damage, it needs proper and comprehensive management, and also to preserve and protect these waters, other studies are needed to have a proper understanding of the water hydraulic system.
