with industrial and economic growth and different material production that humans gained from natural resources for their comfort and walfare, inwardly introduced toxic material and heavy metal entered environment that there created serious problems for themselves and environment. This study accomplished to determine heavy metal concentration (As, Ba, Cd, Hg, Pb, Cr)in water resources and river of Borujerd city in 2008-2009. Materials and Methods: This descriptive cross-sectional study was conducted to determine heavy metal concentration (As, Ba, Cd, Hg, Pb, Cr) in water resources and river of Borujerd city. 54 samples of water were taken from 18 drinking water wells, and also in two times 8 samples of Borujerd river were taken from before and after the city. Then samples carried into the lab and were concentrated ten times using expressed methods and standard methods. Then heavy metal concentration determined by AAP (WFX 130) and results analyzed by SPSS and EXCEL software. Results: Heavy metal concentration average (As, Ba, Cd, Hg, Pb, Cr) in drinking water wells were 0. 0, 0. 3222, 0. 0014, 0. 0002, 0. 0077 mg/l respectively. and heavy metal concentration in river water after the city has been increased than before the city. Conclusion: Results indicated that heavy metal concentration average in Borujerd drinking water wells were lower than standard amounts and drinking water wells didn’t pollute with heavy metal. But heavy metal concentration in river water after the city has been increased than the before of it because city waste water enters the city river.
