Abstract
The principle of Subsurface Arsenic (As) Removal (SAR) is to extract anoxic groundwater, aerate it and reinject it. Oxygen in the injected water reacts with iron in the resident groundwater to form hydrous ferric oxide (HFO). Dissolved As sorbs onto the HFO, which allows for the extraction of groundwater with lower As concentrations.
