Correct Answer

Explanation

concentrations of heavy metals, such as lead, cadmium, or arsenic. These metals can leach into the groundwater from the soil, especially in areas with poor drainage or where the soil is acidic. Additionally, industrial activities, mining, and improper disposal of waste can also contribute to the pollution of underground water by metal ions. It's important to monitor and manage the levels of heavy metals in soil to prevent contamination of groundwater.
