Evaluation of Heavy Metals Contamination in Euphrates River and Some Springs and Wells in Haditha District, Western Iraq
Abstract
For the purpose of assessment pollution in surface, groundwater and some springs in Haditha town - Anbar province during dry season (July, 2022) in term of heavy metal to guarantee their suitability for agricultural and human consumption purposes, the elements Fe, Mn, Zn, Pb, Cd, Ni and Cu were analyzed in twenty-six samples. The average concentrations of these metals were (0.017, 0.154, 0.074, 0.002, 0.001, 0.102, 0.052) ppm in surface water, (0.047, 0.046, 0.014, 0.002, 0.0001, 0.318, 0.012) ppm in groundwater and (0.010, 0.0009, 0.058, 0.1, 0.026, 0.046, 0.002) ppm in springs respectively. Moreover, the concentrations of most elements indicated that they were within the acceptable limits of IQS (2009) and WHO (2017) standards, but the concentrations of (Mn, Ni) in most surface water and some wells, (Pb, Cd) in springs were exceeded the permissible limits. Some high level of the heavy metals could be attributed to the pollution of the water resources with discharge water enhanced with chemical fertilizers, industrial and domestic effluents. (HPI) and (MI) indices were applied to determine the water resources pollution in Haditha. The values of HPI in the water samples referred to unpolluted water except (R1, R2, S1, S2, S3, W2, W4 and W12 samples) were polluted. While the MI values show that all the samples unpolluted except (R1, R2, S1, S2, S3, W2, W3, W4, W5, W9 and W12 samples) were from strongly to seriously affected.
