This study indicated the status of drinking water containing two heavy metals (Zinc and Lead) in case of the areas adjacent to tannery industries located in Dhaka city as well as outside areas. The drinking water was collected from both tube wells and taps, and then metals were determined using Flame AAS. Both Zinc and Lead content was found highest in the tap water of the area of tanneries named Hazaribagh expressing as 54 ppb and 200 ppb respectively. But in tube well water of this area, the amount of Zinc ranges from 31 ppb to 50 ppb but the Lead content was found as nil. Again areas far from tanneries, the lead content was found 138 ppb as highest.
