Abstract: Thirteen groundwater samples were collected from thirteen groundwater wells in different depth and different location inside Shamamik basin in Erbil governorate. The sampling was started in May 2022, and analyzed for heavy constituent such as (Pb, Bo, As, Cd, Zn, Ag, Li, Se, Ni, Cr, and Mn). Majority is to found the samples have concentrations within the acceptable limits as prescribed in Iraqi drinking water standards. The average HPI concentration is 97.66, which is considerably less than the crucial index value of 100. The percentage of groundwater samples that exceed 100-index value is 10%, indicating that the water is completely unfit for drinking while 90 percent are ranging from excellent to very poor quality according to HPI. The MI concentration was 2.7, and 83.3 percent of groundwater samples were found to be very pure water class. The results show that the groundwater in Shamamik basin of wells 27,28,29,30 is highly polluted and unfit for human consumption. Impact of human activity and industrial activity on the study area has played important role of pollution in groundwater quality in the western part of the Shamamik basin. According to finding of current study, can be concluded that the water can be used as safe for drinking without any negatives effect on health human except some few wells in west part of basin.
