Series of chemical reactions of removal of arsenate and arsenite from the groundwater by iron oxyhydroxide with calcium carbonate?

A series of chemical reactions of removal of arsenate and arsenite from the groundwater by iron oxyhydroxide with calcium carbonate is like a filter that cleans the water. It’s like when you pour a cup of muddy water through a coffee filter. The water comes out the other end much cleaner and clear. The chemical reactions work by adding iron oxyhydroxide and calcium carbonate to the groundwater. This helps the arsenic molecules stick to the filter, so that when the water passes through, the arsenic molecules are left behind. Fun Fact: Arsenic is a naturally occurring element that can be found in soil, rocks, and water. It can be dangerous to humans if it’s consumed in too high of amounts.
