Abstract
Compositions including pellets of alum, a smectite mineral material and optionally sodium or calcium carbonate that can be delivered to a phosphate impoundment located at the bottom of a body of water at the bottom. The pellets of alum, smectite mineral material and optionally sodium or calcium carbonate are dropped through the body of water so that the alum is released when the pellet reaches the bottom of the impoundment thereby treating the phosphates.
