IMPLICATIONS OF TEXTILE DYEING AND PRINTING EFFLUENTS ON GROUNDWATER QUALITY FOR IRRIGATION PURPOSE PALI, RAJASTHANJaya S. Ratthore, Vimla Choudhary, Shobha Sharma. Abstract | | | | The dyeing and printing of cotton and synthetic fabrics constitute highly specialized industries at Pali. Pollution of surface water stream has
always implicit effect on groundwater quality and river Bandi is no more an exception. The primary and foremost cause is the release of
untreated effluents in the river by the industries at Pali city. The sodium salts of chloride carbonate, bicarbonate and sulphate are the major
pollutants which have increased significantly in polluted groundwaters besides dyes and organic substances. The application of polluted
groundwater (salinity >8000 µS cm-1
and SAR >30) in agriculture fields has reduced the yields of crops considerably. The majority of well
waters (67.92 %) are characterized (Group V classes) with very high to excessive salinity and sodium hazard (C5S3, C5S4 and C5S5).
Key words: Groundwater; electrical conductivity; sodium adsorption ratio; residual sodium carbonate; irrigation water quality.
