5. Findings and Conclusions
Thirty (30) initial background air samples were collected and analyzed at building 600. Thirty (30) samples were analyzed via phase contrast microscopy (PCM) and seventeen (17) were analyzed via Transmission Electron Microscopy (TEM). Ten (10) bulk samples were collected and analyzed via Polarized Light Microscopy (PLM) and via Transmission Electron Microscopy (TEM). All were below the permissible limits.
Based on EPA Guidelines, we collected one hundred fifty-three (153) bulk samples and analyzed them via Polarized Light Microscopy (PLM) Methodology. Upon the laboratories recommendation one hundred and fourteen (114) samples were analyzed via Transmission Electron Microscopy (TEM) to confirm the findings. Twelve (12) samples collected from eleven (11) apartments were found to be slightly above the regulatory limits of 1%. However, certified asbestos abatement contractors hired independently by the owner, were used to clean those specific apartments found to be in question and the areas were cleared by ALC via TEM sampling. All air samples were found to be well below the permissible limits and the tenants where this cleaning took place have been notified of the clearance.
Two hundred seventy one (271) air samples were collected and analyzed via TEM Methodology. The results indicated that the living areas achieved the acceptance criteria below <70 structures per mm2 set by the above regulations.
