Abstract
A solid phase mixed solvent polymer, compositions and methods for removing and retaining solvated organic compounds and inorganic ions from water, wastewater, superficial and ground water, soil and other environmental sources, a soil amendment and method resulting from adhesively coating the polymer onto sand along with at least one ion exchange material, and methods for the containment, reduction, and prevention of organic leaching from soils, agricultural, industrial, and commercial environments, and in particular, sports and athletic turf facilities such as golf courses where pesticides are frequently applied.
