There are few observations of arsenic transport in aquifers, and its rate of movement is poorly understood. The transport of arsenic, as that of many other chemicals, is closely related to adsorption-desorption reactions (Appelo and Postma, 1993). Arsenate and arsenite have different adsorption isotherms. They, therefore, travel through aquifers at different velocities, and tend to be separated. 

Arsenic transport on particulate iron has been suggested as the cause of higher arsenic concentrations observed in the water piunped immediately after injection of iron- and arsenic-rich water (Appelo and deVet, this...

Taking into account that the arsenate transport is based on an anion-exchange mechanism, the presence of other anions in natural waters could affect the rate of the As transport and its removal efficiency. For this purpose, Milli-Q water was spiked with 10mgL of As(V)...
