Fixed Ambient Air Sampling Locations (Asbestos)
NYC / ER (Sept.26, 12:00 noon to 12:00 midnight) O All 16 samples (including 1 duplicate) were below the OSHA PCM standard and were also below the NYC reentry standard. However confirmatory TEM analysis showed that 4 of these 16 samples were above the AHERA standard (VOS/mm^). (Note: Sample volumes collected were lower than the recommended volumes but were adjusted to detennine if they exceeded established standards.)
O The four samples exceeding the AHERA standard had results of 163 s/mm2, 118 s/mm2, 296 s/mm2, and 74 s/mm2 and corresponded to locations D (East End of Albany Street at Greenwich Street), F (Northern media strip of Vesey and West Street), K (West Street and Albany Street in median strip) and Q (Barclay and West Street (center island), respectively. All these samples are within the immediately impacted area.
