This study is conducted to know the of effect of breeding earthworm for month , two month and three month in soil polluted with the concentration 25,50, 75, 100% of polluted water on its viability. The treatment reduce rate of specificgrowth ratio and it was 59.08 and 78.57% at the concentration 25 and75% respectively , also the treatment cause reducing in the weight of the treated earthworm and it was -0.079 and 0.0787 g at the concentration 25 and100%respectively. This study aimed to know the
