ABSTRACT:
A method of treating dredging spoils for salt contamination having the steps of passing the dredging spoils to a containment area, mixing a solution of calcium and nitrate ions with the dredging spoils, reacting the solution with the dredging spoils so as to form sodium chloride, and draining the liquid component and the sodium chloride from the containment area. The containment area is formed for the receipt of the dredging spoils and piping is extended from a dredge to the containment area so that the dredging spoils can be passed to the containment area. The solution of calcium and nitrate ions is pumped into the flow of dredging spoils toward the containment area. The step of draining includes installing a drainage tile into the containment area below a top surface of the containment area and passing the liquid component and the sodium chloride through the drainage tile to a liquid containment area. The liquid containment area may be the body of water from which the dredging spoils were taken.
