NYC 9/11 Public Portal Document
MMVF Before Cleaning Samples - One wipe sample was collected. The sample was below the detection limit.
Post P‘ Cleaning Samples - Five air samples were collected after the first cleaning. MMVF was below the detection limit.
HVAC System - Four air and two wipe samples were collected after the HVAC system was cleaned. The results for all air and wipe samples indicate that MMVF was below the detection limit and that the air samples were below the primary clearance criteria of 10 SZL.
Post Cleaning Samples - One air sample was collected after the second cleaning. The result was below the detection limit.
PAH Before Cleaning Samples - There were no samples collected before cleaning.
Post P‘ Cleaning Samples - There were no samples collected after the first cleaning.
Total Dust Before Cleaning Samples - There were no samples collected before cleaning.
Post P* Cleaning Samples - There were no samples collected after the first cleaning.
HVAC System - One micro vacuum sample was collected. The results for the micro vacuum sample indicate that dust was present below the clearance criterion of 0.50 mg/cm^. This value is lower than the clearance criterion set by NADCA.
Liberty Street Staircase - The stairwell consisted of cast concrete steps/landings, sheet rock walls and ceiling. All surfaces were covered with gloss paint.
Cleaning Method - This area was cleaned using Test 4A and Test 4B. Test 4A consisted of use of an industrial HEPA-filtered vacuum and an AFD. Test 4B consisted of soap and water wet wipe of all horizontal and vertical surfaces.
Cleaning Results - This area did not meet the primary clearance criterion for alpha-quartz listed in Table 1.0. Due to a delay in receiving analytical results, this exceedance was not identified until after the close of the study. However, the only elevated sampling result for airborne alpha-quartz was obtained from the Liberty Street staircase. This result is inconsistent with the other 53 samples taken throughout apartments and common spaces in the building. Those results were all reported to be below the detection limit. Consequently, the presence of a single elevated sample result in a low occupancy area of the building is not indicative of a health hazard.
Asbestos Before Cleaning Samples - There were no samples collected.
