Abstract

About the vital role of TALAR RIVER in providing drinking water and acting as a source of agricultural water for the lands next to this river and discharge of various contaminants into this river, quantitative examination of river water seems to be needed. But by providing contaminants ZONING and a clear image of quantitative conditions of surface waters by GIS, making any management decisions that will cause direct or indirect environmental impacts on surface waters of the country, become more warily.In this study, which is a kind of sectional study, sampling was done from 6 selected stations (2 upstream stations, 2 middle stream stations and 2 downstream stations) during two periods of high rainfall and low rainfall, in a water year 2012-2013. The results got from laboratory tests were analyzed by quantitative index of NSFWQI and then the path of river was zoned by GIS software.According to NSFWQI, the most suitable conditions belongs to upstream station during high-rainfall period (58, medium condition) and the worst conditions belongs to downstream station during low-rainfall periods (46, bad condition). In accordance to statistical analysis, it became clear that there is a relation between sampling stations and under studied indexes (P-value<0.05).The results of this study showed that among three stations, upstream station water is more suitable for drinking purposes or can be prepared for drinking usages by least treatment and pH adjustment, related to other stations. But the water of other stations must be treated with advanced treatment methods to become acceptable for drinking purposes.
