IN-SITU IMMOBILIZATION OF ARSENIC IN THE SUBSURFACE USING FERROUS CHLORIDE
Roemer, Micha Erhard, Master's thesis, University of Manitoba, Winnipeg. 85 pp, 2017

At a military site in Northern Germany, the aquifer is contaminated by high quantities of arsenic (As) from chemical warfare agents and their degradation products at As concentrations up to 9 mg/L. An in situ arsenic remediation strategy using bivalent ferrous chloride was evaluated in a field trial that spanned almost two yr. The pilot plant immobilized a total of 2.3 kg of As. The objective of this follow-on study was to design a reactive transport model for the As immobilization field trial that would provide a quantitative framework to evaluate As fate in the aquifer system and indicate the effectiveness of the remediation technology. https://mspace.lib.umanitoba.ca/bitstream/handle/1993/32620/roemer_micha.pdf
