Estmaition of Heavy Metals in the Groundwater of Selected Areas From Al-Dhalia District, Al-Dhalia Gov., Yemen

Abstract

In this research, the level of heavy metals Cadmium (Cd), Chromium (Cr), Copper (Cu), Iron (Fe), Manganese (Mn), Lead (Pb) and Zinc (Zn) in groundwater in selected areas in the region of Al-Dhalia district, Al-Dhalia Governorate, Yemen. Sixteen groundwater samples were collected from the study area included 9 artesian wells samples and 7 of hand-dug wells, and analyzed for the presence of heavy metals using Atomic Absorption Spectrophotometer (AAS). The results of the analysis showed that the concentrations of Pb, Mn and Cu in most of the studied samples have exceeded the Yemeni and WHO standards for drinking water, while the concentrations of Fe, Cd, Cr and Zn in most of the studied samples were low and fall within the optimum specifications for local and WHO drinking water.
