Potomac-Hudson Environmental, Inc. (PHEnv) was requested to develop an air monitoring program to measure off-site concentrations of inhalable particulates during excavation and removal of on-site contaminated soils from an active construction site.

As part of the ongoing construction of the Columbus Towers Development Site, it was necessary to disturb and come into contact with the contaminated soils that occupy the site. The native soils were historic fill and were contaminated with elevated levels of heavy metals, PCBs, various polynuclear aromatic hydrocarbons (PAH), volatile organic compounds (VOCs), and total petroleum hydrocarbons (TPH). Several types of operations occurred at the Site that resulted in the movement of site soils and the increased potential for generation of airborne dust and migration of contaminants off-site. These activities included the removal and stockpiling of soils, reshaping of the soils, and the import and spreading of soils. Some of these activities occurred simultaneously.

The purpose of a Perimeter Air Monitoring Plan was to determine the concentration of airborne particulates migrating off-site, and to implement necessary dust suppression measures when airborne concentrations exceeded criteria levels.
