The purpose of this paper is to show the rate of solubility of certain elements (manganese and iron) in impoundment waters. The rate at which manganese and iron becomes soluble is important in determining if there is a change in the solubility of these elements in impoundment water and free running water.

The solubility of an element under impoundment waters represents a cycle. The mud on the bottom of impoundment waters contain the elements that are insoluble. At a certain stage the element becomes soluble, and it is released from the mud. The soluble element is much lighter than the insoluble one, and it therefore rises toward the surface. When it nears the top, there is a reaction; the particles become insoluble. They are heavier than the water particles and fall back down, settling in the mud to start the cycle over again. In impoundment waters, there is a higher degree of soluble particles near the bottom than the top.
