The present study was conducted to evaluate the groundwater quality and its suitability for irrigation purpose through GIS in villages of Chabahr city, Sistan and Baluchistan province in Iran. This cross-sectional study was carried out from 2010 to 2011 the 1-year-monitoring period. The water samples were collected from 40 open dug wells in order to investigate the water quality. Chemical parameters including EC, SAR, Na, Cl, pH, TDS, and IWQI were analyzed. In order to calculate the irrigation water quality index subsequent five water quality parameters (EC, SAR, Na, Cl, and ) were utilized. Among the total of 40 samples were analyzed for IWQI, 40% of the samples classified as excellent water, 60% of the samples in good water category.
本研究旨在通过地理信息系统（GIS）评估伊朗锡斯坦-俾路支斯坦省恰巴哈尔市各村庄的地下水水质及其灌溉适宜性。这项横断面研究于2010年至2011年进行，为期1年的监测期。为调查水质，从40口水井采集了水样。分析了包括电导率（EC）、钠吸附比（SAR）、钠（Na）、氯（Cl）、pH值、总溶解固体（TDS）和灌溉水质指数（IWQI）在内的化学参数。为计算灌溉水质指数，利用了随后的五个水质参数（EC、SAR、Na、Cl和 ）。在总共40个分析了IWQI的样本中，40%的样本被归类为优质水，60%的样本属于良好水质类别。
