Since they may expose to inorganic pollutants, drinking waters should be investigated and
monitored in industrialized regions. In this study, drinking water samples taken from eight different locations
in heavily industrialized region of Turkey, namely Marmara region, were analyzed to determine heavy metal
and harmful trace element (Fe, Co, Cd, Hg, Pb, Zn, Sb, Cu, Ba, Mo, Cr, Mn and V) concentrations. Besides
analytical analysis, principal component analysis (PCA) technique, spatial relationships related to these
metal elements were also examined. Inductively Coupled Plasma-Mass Spectrometer (ICP-MS) was used to
determine the metal concentrations. The average concentrations in ìgL-1 were as follows: Hg. Cd and Co BDL;
Pb 0.18 ; Zn 27.32 ; Sb 0.04 ; Cu 6.35 ; Mn 2.15 ; Cr 1.07 ; V 1.86 ; Mo 0.52 ; Ba 35.22 ; Sr 252. The obtained
results indicated that the heavy metals concentrations in drinking water samples did not exceed the limits
values declared in the guidelines of WHO (World Health Organization), EPA (Environment Protection Agency)
and TSE-266 (Turkish National Standards). However, some V and Cu concentrations found to be very close
to tolerable limits declared by EPA.
