The present study is aimed to assessing the heavy metals concentrations in soil samples of auto-workshops and nearby ground water of Rawalpindi and Islamabad, Pakistan. Thirty Composite soilsamples were collected from auto-workshops and thirty samples of ground water were collectedof the study area to analyzed for selected heavy metals (Cd, Cr, Co, Fe, Mn, Ni, Pb&Zn) by using Atomic Absorption Spectrophotometer (AAS) (Perkin-Elmer model 700, USA). From study it is concluded that heavy metals concentrations in most of the soil samples were found within permissible limits except Zn values, which were found above the permissible limits. In water samples, some of the parameters including pH, Co, Ni, Zn and Mn values were found with in permissible limits while Pb, Cr and Fe at various locations points were noted above the permissible limit of WHO. So it is concluded that workshop area should be cemented and their effluent and waste should be treated properly before disposing off into the surrounding environment in order to eliminate the hazardous impacts on environment, agricultural soil and ground water resources.
