Drinking Water Treatment Residuals as Material for in-situ Capping of Metal Contaminated Sediments

The work that will be performed at Northwestern, within the context of the above referred proposal, consists in the investigation of the coordinative environment of metals – Cu, Cd, Hg, and Zn - sorbed to drinking water treatment residuals and the laboratory study of the release of these metals from capped sediments. In addition, the group will perform a structural study of the material and its evolution during use and assess the bioavailability of metals using prokaryotic biosensors.
