Ground Water Quality Assessment Nearer to the Dye user Industry 

By Gunvant H. Sonawane and Vinod S. Shrivastava 

ABSTRACT

The water quality index (WQI) was calculated for the assessment of ground water quality near to the dye user industry. For the calculation of WQI physicochemical characteristics of groundwater nearby dyeing- printing, pulp-paper and tanning industrial areas were studied. Various physicochemical parameters such as pH, total dissolved solids, total hardness, total alkalinity, calcium, magnesium, chloride and dissolved oxygen etc have been calculated in all the samples. In some of the parameters the concentration observed were found to be above the permissible limits of World Health Organization (WHO), Bureau of Indian standard (BIS) and Indian Council of Medical Research (ICMR). Drinking water was found to be severely contaminated at all the sites of study. Estimated higher values of different parameters verify the results of contamination on the basis of calculated values of water quality indices. 

Key words: Water quality Index, Dyeing-printing, paper-pulp, Tanneries, Physicochemical parameters.
