Which element accumulates furthest in groundwater impacted by forest soil leaching?

💡 Explanation

The mobilization of soil compounds via eluviation increases calcium ion concentration due to their high solubility because cations experience less electrostatic binding within mineral complexes. These calcium ions tend to move further into groundwater rather than larger, less mobile colloids and mineral sediments during eluviation. Therefore, calcium is the deepest.
