| VAPOR INTRUSION MITIGATION, USEPA BUILDINGS, RARITAN ARSENAL EDISON, NJ 2005 |
Re-designed and installed 16 multi-point Active Soil Depressurization systems in three separate buildings. Prior to installation the specified systems were re-designed to correct design deficiencies that would have created condensation problems. The first building is a 92,800 square foot single story office and warehouse, the second and third buildings are multi-storied office buildings. All three buildings are constructed of steel, poured concrete, and brick. Post remediation indoor VOC concentrations are at non-detect or below New Jersey health based screening values. It is critical that ultra low or non-detect VOC concentrations be maintained in this complex since it is the storage location for the US EPA’s Trace Atmospheric Gas Analyzer (TAGA). This is one of two mobile pieces of equipment owned by the government that can, in real time, analyze VOC 's in the part per trillion range. The effectiveness of our Vapor Intrusion Systems provides the clean atmosphere required for the storage of this sensitive instrument.
