dc.description.abstract Permeable reactive barriers are considered among the most promising technologies for contaminated soil and groundwater remediation. Zero-valent iron (ZVI), hydroxyapatite (HA), and organic compost, with (OM) and without (OMx) dextrose/sulfate were assessed in column studies for their ability to attenuate chromium (Cr) or cadmium (Cd). PVC columns were packed with the reactive media and Cr or Cd solutions were pumped through the columns at concentrations of 5, 50 and 200 mg/l. These media were also assessed for their abilities to attenuate Cr and Cd from a contaminated soil. The order of Cr removal was: ZVI > OMx > OM > HA. The ZVI treatment maintained a removal rate of > 95% throughout the study. All treatments used for Cd removal had a removal rate of 98% across all treatments. The ZVI was the only treatment capable of retaining any of the mobile soil Cr and Cd from the contaminated soil.
