Relatively high concentrations of naturally occurring arsenic in rivers can occur as a result of geothermal activity or the influx of high-arsenic groundwaters. Arsenic concentrations of 10-70 p,gL have been reported in river waters from geothermal areas, including the...

Dissolved As speciation is important in determining the extent of reaction with the solid phase and therefore the mobility of As in groundwater. Arsenic is generally present as arsenate [As(V)] or arsenite [As(III)] for Eh conditions prevalent in most groundwaters (Fig. 1). Arsenic metal rarely occurs, and the -3 oxidation state is found only in very reducing environments. Arsenite has been considered to be the more toxic oxidation state (U.S. Enviromnental Protection Agency, 1976) however, more recent studies have shown that most ingested As(V) can be reduced to As(III).
