Description:
Permeable iron reactive barriers have become a popular way to remediate contaminated ground water. Although this technology has been in use for about a decade, there is still little knowledge about long-term performance issues (l). One of the biggest concerns is the corrosion of the iron materials. We studied these effects using a Scanning Electron Microscope equipped with an energy dispersive X-ray analyzer. We developed methods for mapping elemental abundances and associations to better understand iron corrosion processes.
