A reactor system for decontamination of water by photolytic oxidation utilizing near blackbody radiation, the system comprising (1) a reaction chamber defining an internal space with an inlet and an outlet; and (2) a plurality of broadband radiators for generating radiant energy with wavelengths between about 150 nm and about 3 mum, the broadband radiators disposed within the reaction chamber such that a sufficient dosage of broadband radiation deeply penetrates the water matrix and irradiates the contaminants and/or the oxidant within the internal space of the reaction chamber thereby causing photolytic oxidation of the contaminants. In a preferred embodiment, residual hydroxyl radicals in the form of hydrogen peroxide or similar oxidants are formed in the contaminated water, thereby decreasing the need for use of adjunct chemical or other oxidants. In a preferred embodiment, the plurality of flashlamps have a minimum spacing between about 12 inches and about 24 inches. A preferred embodiment of the invention delivers ultraviolet radiation having a continuum of wavelengths between about 260 nm and about 265 nm to the water, the radiation having a depth of penetration into the water matrix greater than between about 40 times, and about 50 times that of a mercury vapor lamp which exhibits atomic line or other non-continuum radiation at primarily 254 nm.
