In Situ Permeable Reactive Barriers Brochure

In situ reactive barriers, i.e. treatment walls, are replacing pump and treat remedies for contaminated groundwater with cost savings greater than 75%. Iron reactive permeable barriers remediate chlorinated solvent contaminated groundwater by abiotic degradation of the halogenated volatile organic compounds into harmless daughter products. Azimuth orientated vertical hydraulic fracturing is an alternate mode of placing iron reactive barriers in situ, resulting in significant cost savings and allows reactive barriers to be installed at greater depths than conventional technologies. Orientated vertical fracturing technology has installed permeable iron reactive barriers at a number of sites in highly permeable sands and gravel down to moderate depths and a number of cases greater than 100.
