The study was conducted in water supply of different localities of Ludhiana with the objective to screen the concentration oftrace elements (As B Ca Co Cr Cu Fe K Mg Mn Na Ni Pb Zn). The study revealed that concentration of Pb , Cu, Fe, Cr, K, Na, Co, and Ca in twenty one drinking water samples analyzed from three different water utilities [Municipal Corporation (12), hand pumps(6) and submersible pumps (3)] were much below the permissible limits described by WHO and BIS. Zinc was detected in 95.45% of drinking water samples in the range 0.001-0.14 and boron detected in 85.71% of drinking water samples in the range of (0.002-0.1327) whereas Arsenic was detected in 19.04% of the water samples analyzed in the range of 0.006-0.01 mg/l. All the 21 samples depicted Nickel (Ni) and 57.14% of samples had Ni concentration >0.1mg/l (BIS), while in rest of the samples Ni was present in ranges of 0.0091-0.047mg/l. Only one sample out of 21 samples contained Arsenic and Manganese above permissible limit.
