RBCA at a former military site[Risk Based Corrective Action]
Federal and military sites all over the world are the scenes of numerous releases of hazardous substances. The varied nature of the contaminants found at these sites poses a challenge to remediating these sites successfully at an economical prices. These soils contaminated with organic pollutants and heavy metals, pose toxic threats to public health and the environment, and potential loss of natural resources. One such site of concern is the former 37.66-square kilometer US Naval Facility (NAVFAC) in Argentina, Newfoundland. The Government of Canada is interested in having this site remediated to an acceptable state. The traditional approach to remediating such sites, the RI-FS (Remedial Investigation and Feasibility Study) approach, is no longer thought to be adequate. Now more focused risk based clean-ups of sites based on the intended use of the site are increasingly being looked upon as more appropriate. With the NAVFAC site as the focus point, this paper presents an overview of the RBCA (Risk Based Corrective Action) approach in the context of remediating federal and military sites. The advantages and disadvantages of RBCA are examined in the paper. The risk assessment at NAVFAC is reviewed and a case is made for Tier 3 RBCA. This overview is of relevance to the remediation of other similarly contaminated sites.
