SuratGIDC,Gujaratisoneofthe largest producersintextile industryinIndia.The ever growingdemandisfulfilled by veryfast supplying process,thisleadstobad practicesduring textiles operationswhichcauseswater pollution in thisregion. Since Surat iscloser to the Arabian Sea, the polluted wateris passed in to the sea through various waterchannels therefore, it is necessaryto identify and characterize hazardous substances from these effluents. For this study samples were collected from two important textile industry clusters viz. Sachin and Kadodara, GIDC, Surat and stored by following standard sampling procedures. Physico-chemical parameters such as pH, Chloride, Sulphate, Electrical Conductance, Total Dissolve Solid, COD and BOD were determined. Solvent extraction method was employed to prepare samples for the detection of organic substances by FTIR and GC/MS techniques. FTIR confirmed the presence of various functionalities related to organic origin and GC/MS technique revealed the presence of linear, cyclic and polycyclic aliphatic and aromatic organic compounds in the collected samples with high toxicity. Physico-chemical parameters were used for the statistical analysis of water samples and standard statistical methods such as mean, errors, standard deviation, regression coefficient analysis and correlation were used which were helpfulforthe determinationofwater qualityindex and the results obtainwere compared to assignthe water qualitystandards authenticated by WHO, USPH and BIS. The prime focus was to detect organic pollutants and the assessment proved the presence of hazardous organicsubstances in the collected textile effluentsamples.
