Project Experience: Indoor Dust Test

As an EPA contract laboratory, EMSL Analytical, Inc. was selected as the analytical laboratory for the World Trade Center (WTC) test and clean project. This Test and Clean Program plan was the result of ongoing efforts to monitor the current environmental conditions for residents and workers impacted by the collapse of the World Trade Center (WTC) towers. Over a one year period, EMSL analyzed more than 10,000 samples including air samples via transmission electron microscopy (TEM) AHERA, phase contrast microscopy (PCM) NIOSH 7400, settled dust via TEM Microvac ASTM D5755-03, and man-made vitreous fiber (MMVF) analysis via scanning electron microscopy (SEM).
