Claim:
An apparatus for treating subsurface water comprises: a well having a casing with an inlet screen and outlet screen to promote a recirculation of water into the casing and through surrounding ground area, at least one microporous diffuser disposed in the injection well that allows delivery of first and second fluids with one of the fluids forming a coating over the other one of the fluids; an ozone generator; an air compressor and compressor/pump control mechanism to deliver ozone (O3) from the ozone generator to the microporous diffuser as one of the fluids; a source of the liquid hydroperoxides selected from the group consisting of formic peracid, hydroxymethyl hydroperoxide, 1-hydroxylethyl hydroperoxide, and chloroformic peracid or their derivatives; and a feed mechanism to deliver the selected liquid hydroperoxide to the microporous diffuser as the second one of the fluids.
