Extended Abstract
Introduction and Objective: This project was carried out, in order to food security, according developing agriculture and sustainable natural resources and optimum utilization of water resources with evaluation and quality effects of infiltrated runoff to aquifer.
Material and Methods:  In this study use of determine local Pollution Sources, sampling of surface runoff and groundwater in the aquifer that feeds the violation of pollution sources, according to FAO and WHO standards methods for agricultural, domestics and provided layer maps with geographic information system software and quality indexes analysis duration three years. The current research was conducted, for evaluation of transferred run off on water quality aquifer. In this study, were taken seasonal samples from 16 tube wells for determine the concentrations of sodium (Na), potassium (K), calcium Ca), magnesium (Mg), chloride (Cl), sulfate (SO₄), carbonate (CO₃), bicarbonate (HCO₃), Electrical conductivity (EC), acidity (pH), total dissolved solid (TDS), in order to determine the water qualitative indicators including, sodium absorption ratio (SAR), percent sodium (%Na), residual sodium carbonate (RSC), permeability index (PI), total hardness (TH), were indexes of water quality, The groundwater quality is categorized into various levels based on the FAO and WHO standards for the purpose of irrigation and domestic use respectively.
Results: Contamination view of the BOD₅ concentration was measured and all samples in various locations under artificial recharge project located were complete infected for drinking purposes. Amounts of acidity were 6.4 to 8.4, SAR less than 3, Sodium percent less than 40 percent and infiltration index equal 0.39 to 0.68. In terms of drinking water, chloride, sodium, sulfate, were normal and unrestricted, but water hardness was a little beyond the normal Limit. Of view contamination, was measured BOD₅ concentrations in the regional. Concentration of heavy metals, arsenic, aluminum, chromium, cadmium, lead, manganese, iron, zinc and copper were measured and analyzed then were less than normal level and were complete suitable for various activities.
Conclusion: The implementation of artificial recharge project has a positive effect on the aquifer recharge of the region and the aquifer water of Sefiddasht- Faradenbeh plain is suitable for irrigating the agricultural lands of the region and does not have any restrictions.
