JRW Bioremediation is an innovator in the development and implementation bioremediation ammendments for in situ bioremediation of chlorinated solvents, perchlorates and metals. We offer two families of bioremediation products to the environmental engineer/consultant, based on the hydrogeology, subsurface structure, and time & budgetary constraints. The first are soluble ammendments for fast acting rapid bioremediaton, the second are slow release compounds for permeable reactive barriers with multi-year longevity.
