Abstract The objective of this study is to assess the levels of heavy metals (lead, cadmium, zinc, copper, and nickel) in the village’s water and soil. The amount of heavy metals found in the water and soil in the Abu Al-Jir region and Hit District was examined. Nitric acid and hydrochloric acid were used in a 1:3 ratio to dissolve soil samples. An atomic absorption apparatus was then used to analyze it. Lead was the top soil pollutant reaching 46-23.175 mg/kg (permissible limit 15 mg/kg). As for the nickel element, the contamination was partial (28.925-8.35 mg/kg, permissible limit 17 mg/kg). The zinc element was found in all samples to be within the acceptable range of 6.15 to 19.875. The maximum amount allowed was 35 mg/kg. The only contaminants found in the water samples were lead and cadmium; the highest concentration, 1.18 mg/kg, was found near busy roads, and the lowest concentration, 0.883 mg/kg, was likewise higher than allowed limits. The acceptable limit for cadmium contamination was 0.01 mg/kg, and the range was 1.199–0.066 mg/kg. Regarding nickel, several samples fell within the acceptable levels of 0.354 and 0.01 mg/kg, while others were marginally beyond them. The acceptable limit was 0.1. The inhabitants of this area are at risk, thus care must be taken because they are unfit for drinking and cultivation due to the high levels of pollutants present).
