Water quality assessment of surface and groundwater sources used for drinking and agriculture

Sustainable development is the most important challenge of human society in this century. In this regard, access to sufficient water resources of high quality is one of the effective factors to achieve sustainable development. One of the important applications of surface and groundwater resources is irrigation of agricultural products. Irrigation water quality affects soil quality (Kondash et al., 2020) and agricultural health (Aravinthasamy et al., 2020). Assessing the quality of water resources is one of the main requirements in the management, planning and development of water resources and their protection and control (Kumar et al., 2019). Given that the city of Malayer is globally known for its grapes, the study of water quality in this region is of great importance. One of the most effective methods for assessing water quality is the use of appropriate indicators for the assessment. Quality indicators convert the values ​​of water quality characteristics (measured parameters) into a number to be used in the management and analysis of water quality and monitoring of water quality changes over time and place (Carbajal-Hernández et al., 2013).
