Abstract

Subsurface arsenic (As) removal is a technology based on injection of aerated water into an anoxic or anaerobic aquifer that is rich in both iron and As. This injection procedure will onset the oxidation of adsorbed Fe(II), resulting in the formation of Fe(III) oxides for subsequent As adsorption during abstraction. The series of studies executed between 2008–2014 have shown that achieving high V/Vi ratios, i.e., ratio between abstracted and injected volume, with low As concentrations is challenging. Experimenting with operational conditions can enhance performance, as well as choosing geochemically favorable conditions, however, in this study water revenues remained below V/Vi = 2.
