Abstract
A treatment composition for treating contaminated material is disclosed which has water, coal, and an alkali metal carbonate. In another aspect an additional ingredient is a seaweed derivative. A method for making such a treatment composition for treating contaminated material has been developed which includes introducing water into a first tank, blending in alkali metal carbonate in the first tank with the water to form a first composition, adding coal to the first composition and blending them together forming a base composition, introducing one half of the base composition from the first tank into a second tank, introducing an amount of seaweed derivative into the second tank equal in volume to the amount of base composition in the second tank, and blending the contents of the second tank together producing the treatment composition. Methods and materials for soil treatment have been developed in one aspect for remediating hydrocarbon and/or brine contaminated soils; in one embodiment, material having water, soft coal, potash and, if desired, algin extract is applied to the soil; in one embodiment microorganisms are added to one soil.
