Assessment of salinity and corrosion potential of Sari groundwater with emphasis for using in industry, agriculture and urban

Assessment of Sari area groundwater can determine the qualification of water and performance of this for different use such as industrial، urban and agriculture. There are similar researches in different area of Iran country for this topic. With study 20 different sampling point of groundwater source for this research are and chemical and physical test result، the sodium absorption ratio determined and salinity dispersion map was drawn. After that with using indexes LSI and RSI corrosion and sedimentation was examined. with calculating SAR، was shown the bad quality of groundwater resource for agriculture and in rating perch in salinity and very salinity. Also with drawing of salinity dispersion map the critical area was shown. In assessment of LSI and RSI specified that all results of LSI are sediment property. As well as sedimentation dispersion map was shown that، there are maximum of sediment in center of study area. The sampling water of research area is with high level of SAR and salinity. Also high sediment can do bad effect on agriculture، industry and human health. Decrease of using resource and use phosphate composite can decrease the effects.
