Description:
Recent experimental results provide evidence that dissolved inorganic carbon plays a direct role in mobilizing arsenic in anoxic aquatic environments. This hypothesis is partially supported by observed correlations between elevated levels of arsenic and alkalinity in a ground water aquifer containing buried arsenic-rich sulfidic waste materials. However, the influence of dissolved inorganic carbon is difficult to decouple from the effects of elevated pH and/or microbial processes. Laboratory experiments are being conducted to explore the effect of inorganic carbon on arsenic sulfide solubility. These experimental results along with a site-specific review of ground water geochemistry within an arsenic plume will be reviewed in order to explore the validity of the proposed correlation.
