Introduction: Groundwater contamination has major effects on human health, industrial activity, agriculture, and the environment. The present study determined the concentration of lead, cadmium, arsenic, chromium, and nickel metals in the groundwater around the landfill in Juybar City and compared them with the drinking water standards.
Materials and Methods: In this descriptive-analytical study, 12 samples were sampled from four wells for three consecutive months. The concentration of heavy elements was measured using the graphite furnace atomic absorption technique (GFAA) based on standard water and wastewater methods. Also, the hardness, temperature, pH, and total dissolved solids (TDS) parameters were measured with portable devices.
Results: Investigations showed that the average concentration of nickel, lead, chromium, and cadmium in well water was 0.0425, 0.0071, 0.0268, and 0.0117 mg/l, respectively. The average concentration of arsenic was not observed in any sample. The average temperature, hardness, pH, and TDS were measured in the range of 20-21°C, 108.66-136.33 mg/L, 7.3-7.36, and 566.25-712.33 mg/L. Also, the correlation coefficient showed a positive correlation between the metals nickel, chromium, lead, and cadmium and the parameters of temperature, hardness, pH, and TDS, as well as with each other at a confidence level of 0.01.
Conclusion: The amount of arsenic, lead, chromium, pH, and hardness are acceptable in the investigated wells for drinking purposes, but the amount of cadmium, nickel, and TDS is higher than the standard.
