Abstract: A method of incorporating a peroxide source that produces reactive oxygen species and optionally also incorporating steam with the peroxide source (or other source of heat), into soil as a method of soil remediation, i.e., to destroy or remove chemical contaminants that pose a threat to plant or animal life. The invention also relates to the use of the peroxide source along with optional steam (or other heat source) or hot vaporized peroxide solution to treat soils, in particular those intended for agriculture, as a pesticide for controlling nematodes, pathogenic fungi, insect pests and bacteria. The peroxide source may be applied to the soil using soil cultivation equipment to increase contact between the peroxide source and the soil to be treated. The peroxide source and/or steam or other source of heat or hot vaporized peroxide solution can also be applied with injection wells or infiltration galleries, for instance, for the pesticide use and soil remediation.

Abstract: A peroxide delivery system is produced. The peroxide delivery system includes a dry powder that releases the peroxide quickly and completely when needed. The peroxide delivery system may be produced by combining a liquid peroxide or peroxide solution with an inorganic solid support that is inert to the peroxide and is capable of adsorbing large amounts of the liquid peroxide or peroxide solution while remaining dry to the touch. Methods of combining the inorganic solid support with the liquid peroxide or peroxide solution are disclosed. The peroxide delivery system can be formulated in preparations of powders, liquids, foams, sprays, gels, ointments, creams, sticks, or pastes that can be utilized in a variety of applications such as cleaning, stain removal and antiseptic products, for example.
