USE OF MONITORED NATURAL ATTENUATION FOR INORGANIC CONTAMINANTS IN GROUND WATER AT SUPERFUND SITES
U.S. EPA, Office of Solid Waste and Emergency Response.
OSWER Directive 9283.1-36, 83 pp, Aug 2015
Filed Under: General News
Filed Under: General News
This new monitored natural attenuation (MNA) directive for inorganic contaminants expands upon and is designed to be a companion to the 1999 MNA guidance. Together, these two policy documents provide guidance on the consideration of MNA for a broad range of contaminants at Superfund sites. Both directives say that multiple lines of evidence should be obtained to evaluate the feasibility of including MNA in the site's selected response action. This 2015 guidance builds upon the approach indicated in the 1999 directive for tiered analysis of site characteristics that control and sustain attenuation, and recommends a phased analytical approach tailored specifically for inorganic contaminants. Both guidance documents are available at http://www.epa.gov/superfund/health/conmedia/gwdocs/monit.htm
