5 87th Air Base Wing Action Item Update McGuire Site TU023 Mr. Tim Llewellyn, Senior Vice President ARCADIS

6 McGuire Site TU023: Former Pumphouse B1707 Jet fuel compounds present in soils due to leaks from former JP-4 USTs Biosparging is the selected remedy at this site Similar to an AS/SVE system but injection of oxygen into the ground is intended to enhance degradation of contaminants inplace more than remove them in recovered air 3,800 pounds of contaminant mass estimated in the subsurface 110 pounds removed to date Soil sampling is planned this month to assess positive impact of system after 6 months operation 6
