description: The Directorate of Public Works Environmental & Natural Resources
 Division (Fort Stewart /Hunter Army Airfield) contracted with the Pacific
 Northwest National Laboratory (PNNL) to monitor particulate matter (PM)
 concentrations on Fort Stewart, Georgia. The purpose of this investigation was
 to establish a PM sampling network using monitoring equipment typically used
 in U.S. Environmental Protection Agency (EPA) ''saturation sampling'', to
 determine air quality on the installation. In this initial study, the emphasis
 was on training-generated PM, not receptor PM loading. The majority of PM
 samples were 24-hr filter-based samples with sampling frequency ranging from
 every other day, to once every six days synchronized with the EPA 6th day
 national sampling schedule. Eight measurement sites were established and used
 to determine spatial variability in PM concentrations and evaluate whether
 fluctuations in PM appear to result from training activities and forest
 management practices on the installation. Data collected to date indicate the
 average installation PM2.5 concentration is lower than that of nearby urban
 Savannah, Georgia. At three sites near the installation perimeter, analyses to
 segregate PM concentrations by direction of air flow across the installation
 boundary indicate that air (below 80 ft) leaving the installation contains
 less PM2.5 than that entering the installation. This is reinforced by the
 observation that air near the ground is cleaner on average than the air at the
 top of the canopy.
