Abstract

Analysis of water samples involves measuring density of main cations and anions and parameters Iranian National Standard was used for analyzing. Samples were collected from 22 areas and different physico-chemical parameters such as pH, EC, TDS and major anion, cations and some parameters such as SAR, PI, KI and etc, were assayed by chemical relations, to evaluate the quality of groundwater and its property for irrigation. Due to the Gibbs diagram, samples which are formed, affecting by geological formations, Caspian Sea salt water intrusion and connate water aquifers, are in areas of rock-water, evaporation and crystallization reactions. Therefore groundwater quality will decrease for using in agriculture and the other consumptions and also infiltration of them will not be useful. Area of study is suitable and allowed, according to different methods of the water sources surveying.
