    This study mainly refers to investigate the environmental impact of textile effluents discharged after dyeing cotton knit fabric with eight different reactive shades. By this work it was possible to evaluate the influence of each shade on the present ecological system. Textile effluents generated after dyeing with eight shades were collected to analyze the ecological parameters, including acidity or alkalinity (pH), amount of dissolved oxygen (DO), total dissolved solids (TDS), temperature and visual colors. From the experimental data it can be said that the effluents produced from the dyeing process comprising primarily more alkalinity, less DO, more TDS, high temperature and nearly black color which have indubitably adverse effects on the biological system. Furthermore, all reactive dyes were not found to be equally responsible to affect the surroundings. Hence, this research work becomes vital to recommend a suitable reactive dye having low impact on the environment.
