Abstract—The main objective of this paper is the assessment of surface water quality polluted with various heavy metals (HM) using the quality indices and the information submitted may be useful for the competent authorities and the public. Cadmium (Cd), iron (Fe), manganese (Mn) and zinc (Zn) were determined from water samples of Socea Valley using the Atomic Absorption Spectrometry technique. The calculated water quality indices indicate that the monitored surface water between 2011-2014 years was deteriorating due to the former mining activities from this area. Most of the HM levels were highest compared to the acceptable standard limit. The level of Hevy Metal Evaluation Index (HEI) shows that the water quality falls within the low quality class and the values of Degree of Contamination (CdI) shows a high contamination. Also, the correlation matrix was performed between the analyzed heavy metals. The results obtained for the Pearson’r coefficient showed positive values for all heavy metals and between Fe and Mn the value of r being 0.933. All data revealed that the water from Socea Valley is not safe especially for drinking and irrigation purposes.

Index Terms—Heavy metals, mining, polluted aquatic environment, water quality indicies.
