Assessment and Spatial Variability of Groundwater Resources for Corrosiveness and Scaling Potential in North of Qazvin Plain, Iran

Water quality is very important for all humans such as drinking, irrigation and industrial consumption.Increasing water corrosiveness and scaling in the pipes and reservoirs of water distribution network for drinking andIrrigation could raise serious problems. In this study data of water quality analysis samples from 17 wells in the northof Qazvin plain had been used. Water samples classified based on Langelier Saturation Index (LSI), Ryznar StabilityIndex (RSI), Larson-Skold Index (LS Index)and Puckorius Scaling Index (PSI) with spatial analysis of this indices were performed using IDW interpolation model. Result of LSI index shows that 88% of study area samples are corrosive. RSIand PSI results indicate that study area had high aggressive water. LS index result shows most of samples of study area(59%) were not interfere of Chloride and Sulphate. Result of spatial distribution shows that scaling potential of study area samples increased in western and eastern parts are corrosive. Eventually results estimate that study area groundwater sources are suitable for irrigation uses, but with high corrosion condition
