NOVELTY - The contaminate treatment involves treating contaminate contaminated with organic compound (OC) by chemical oxidation, which involves contact with soluble transition metal (TM), TM chelator to form TM-chelator complex (TMC), and oxidizing agent that provides reactive free radical which initiates chemical reaction with OC to form reaction products in presence of TMC, and buffering salt to maintain neutral pH.    USE - For treating contaminates in particulate such as soil, and fluids such as ground water, and for particulates contaminated with organic material such as hydrophobic aromatic hydrocarbons.    ADVANTAGE - The contaminate treatment is effective, safe, and inexpensive. The treatment provides effective degradation of pollutants, reduces toxicity and chemical or biological oxygen demand, and removes odor or color of contaminate. The treatment provides low environmental impact, easy application of inexpensive microbiological consortium to the contaminate. The presence of chelating agent stabilizes the reactive transition metal ion in the complex and prevents precipitation as ferric salt without inhibiting catalytic activity of transition metal ion. The transition metal ion enhances the production of highly reactive oxidizing free radical.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a method of producing reactive free radical in an aqueous medium in a neutral pH range, involving providing an aqueous medium comprising a soluble transition metal, a chelator of the transition metal to form a transition metal-chelator complex and an oxidizing agent that provides a reactive free radical in the presence of the transition metal-chelator complex; and    (2) a kit for treating contaminate contaminated with organic compound, comprising transition metal, chelator of transition metal having the property of forming transition metal-chelator complex with transition metal, buffering salt soluble in acidic solutions or having pKa suitable to maintain pH in neutral range.
