To estimate quality of water in coastal region of Surat district, the study was made by us. Ground water samples were collected from different sampling stations of coastal villages of Olpad and Choryasi talukas of Surat district, Gujarat (India). The samples were collected from 20 different locations and analyzed for physico-chemical properties and different indices were calculated. Seasonal study was carried out for all these stations from May 2015 to April 2016. In this study, The results are compared with water quality standards laid down by ICMR and WHO. The results revealed that some of the samples were having high concentration of salts causing deterioration in quality of drinking water.</p> https://journalofchemistry.org/paper/577/ Ground water Physico-chemicals parameters Corrosion indices ICMR, WHO Olpad and Choryasi Taluka
