Popis:	The present work is a comprehensive evaluation of surface and ground water quality of Haripur basin (comprising an industrial estate), Pakistan. Heavy metals, trace elements (i.e., Cd, Cr, Cu, Pb, Fe, Ni, Zn, Co, Mn, As and Hg) and physical parameters such as pH, total dissolved solids (TDS) and electrical conductivity (EC) were investigated in 98 sampling points and compared with the WHO guidelines for drinking water. The average metal concentrations in surface and ground water were found in the order of Fe > Mn > Zn > Ni > Pb > Co > Cr > Cu > Cd > As > Hg and Zn > Fe > Pb > Mn > Cr > Cu > Ni > Cd > Co > As > Hg respectively. Furthermore, chronic daily intake (CDI) and hazard quotient (HQ) were also calculated. HQ was found to be
