Abstract Toxic metal pollutants in groundwater should be identified to prevent future health risks. In this paper, the presence of heavy metals in groundwater in the western region of Iraq was investigated. The heavy metals concentrations, including Ni2+, Co2+, Zn2+, Pb2+, Cr3+, Cd2+, As3+ and Hg2+ were explored in twenty selected aquifers near Rutba City and the results were presented as spatial distribution maps. Findings indicate that contamination with the investigated heavy metal ions possesses a serious threat to the study area’s groundwater quality when compared to WHO and IEPA guideline values. Thus, a new approach to remove or adsorb heavy metal ions can be developed for large-scale production and the safe use of these aquifers water. Results revealed that the highest concentrations in mg/L1 of 2.312 in w19, 1.098 in w2, 5.78 in w17, 0.292 in w9, 3.349 in w5, 0.32 in w13, 0.074 in w11 and 5.622 in w1 for Zn2+, Cr3+, As3+, Pb2+, Ni2+, Co2+, Cd2+ and Hg2+ were recorded, respectively.

Developmental activities, geological reasons and mixing of industrial wastes are responsible for the deteriorating quality of surface and ground water in the Himalayan state of Uttarakhand. The drinking water sources of 13 districts of Uttarakhand have been assessed for the presence of four toxic metal ions (arsenic, cadmium, chromium and lead). The health aspects of the four metal ions have also been reviewed according to the prescribed limits set up by the Bureau of Indian Standards (BIS) and World Health Organization (WHO). The present study reveals the absence of arsenic at almost all stations. Cadmium has been found only at Rudrapur, whereas chromium is found to be present in more than prescribed limits, in Kolti, Mussoorie and Dehradun. Significant presence of lead in the six districts of the state is indicative of the fact that proper management strategy of toxic metal ion remediation is required. Chromium and lead have exceeded the prescribed limit in 1.3 and 4.5% samples, respectively. However, as per BIS standard, cadmium is higher than the prescribed limit in 0.6% samples but according to the WHO standard, cadmium has exceeded in about 26% samples. Out of the total 156 samples analyzed, 6.4 and 33.3% samples have been found to possess the toxic metal ions in more than the prescribed limits as per BIS and WHO guidelines, respectively.
