In order to investigate the effect of using treated wastewater in agriculture on the chemical quality of groundwater in the northern region of Isfahan, an area of 6000 hectares was studied during the years 2018 and 2019 by sampling 46 wells. The location of the studied wells was in two areas under long-term irrigation with effluent for at least 10 years and the control area. Chemical quality characteristics of the samples included electrical conductivity (EC), chemical reaction (pH), anions including bicarbonate, sulfate, chloride, nitrate and cations including calcium, magnesium and sodium. The results showed that the effect of using treated wastewater on the quality of groundwater in the region, in shallow and deep wells has a different behavior. Due to the long-term use of treated wastewater for irrigation of agricultural lands, none of the parameters of groundwater chemical quality were significant for samples in deep wells compared to the control area. For samples in surface wells compared to the control area, for chemical parameters EC, bicarbonate (HCO3) and chlorine (Cl) at the level of 5% percent probability had a statistically significant difference. Most of the wells in this area are deep and only 8% of the wells in the area are shallow. Therefore, according to the results, the use of treated wastewater for agriculture in this region has a negligible effect on the chemical quality of deep groundwater and therefore is recommended for use in agriculture.
