  Weiss's Anja Verce Presented at the 2014 Battelle Chlorinated Conference
 May 2014
Anja Verce, Environmental Engineer at Weiss   Associates, presented "Making the Case for Monitored Natural Attenuation at a   High Profile VOC CERCLA Site in California" at Battelle's Ninth International Conference on Remediation of Chlorinated and   Recalcitrant Compounds in Monterey, California on May 20,   2014.
 Anja's platform presentation, co-authored by Mary   Stallard, PG, CHG, of Weiss Associates,  described how Weiss demonstrated   ongoing monitored natural attenuation (MNA) at a site where significant   contaminant mass was removed previously with enhanced reductive dechlorination   (ERD) via bioremediation. To verify the efficacy of MNA at this site, Weiss   analyzed concentration trends of volatile organic compounds (VOCs), compared   current and historical contours of VOC concentrations, and calculated mass flux   and discharge over time at the site boundary. In addition, we confirmed with   indoor air sampling that no vapor intrusion risk exists for VOCs and   methane.
