Remediating Subsurface Arsenic Contamination with Monitored Natural Attenuation
High levels of arsenic in water fall at the top of most lists of hazardous environmental compounds. However, at some sites where contamination poses no immediate hazard to human or ecosystem health, the risks associated with arsenic migration and exposure may be mitigated by natural attenuation. H. James Reisinger and David R. Burris with Integrated Science & Technology, Inc., and Janet G. Hering from the California Institute of Technology discuss guidelines for monitored natural attenuation of arsenic and offer a few examples of natural processes at work.
