Phulali canals passes through Hyderabad city with a population of about 2 million. Most of the municipal and city industrials effluent is added to canal water during of 14km and has direct impact on the health of human beings, crops and cattle life. The levels of trace and toxic elements are found higher in the order > Mg (249.53mg/l)> Ca(83.446mg/l)> Na(45.778 mg/l)> K(11.697 mg/l)> Al(1.592mgf/l)> Fe(1.451mg/l)> Mn(0.596mg/l)> Ba(0.576mg/l)> Zn(0.167mg/l)> Co(0.151mg/l)> Cr(0.0082mg/l)> Pb(0.2026mg/l)> Cu(0.063mg/l)> Cd(0.004mg/l)>Ni(0.005mg/l). strong positive correlation also exists for certain pair of elements like Mg-Cu(r=0.963), Na-Ni(r=0.932), Ba-Zn(r=0.929), Al-Mn(r=0.941), Cd-Ba(r=0.448), Cr-co(r=0.366), Pb-Cu(r=0.238), Zn-Fe(r=0.212) and Fe-Co(r=0.154). the results have been compared with NEQs, drinking water upper limits for human beings and livestock, irrigation water limits and aquatic life protection limits. The levels of manganese, iron and cobalt are found higher than the irrigation water restriction values and overall water is poorly unsuitable for drinking of livestock, aquatic life and for irrigation purposes in the long run.
