Post P‘ Cleaning Samples {Test 3B) - Two air samples, two micro vacuum samples, and four wipe samples were collected after the first cleaning. The two air samples were below the primary clearance criterion of 1.0 pg/m^. The results of the micro vacuum and wipe samples show that all samples met the comparison value or primary clearance criterion for lead.
Alpha-Quartz Before Cleaning Samples - Pre-cleaning air samples were not collected.
Post P‘ Cleaning Samples - Two air samples were collected after the first cleaning. Both were below the detection limit.
Cal^ Before Cleaning Samples - Pre-cleaning air samples were not collected.

MMVF Before Cleaning Samples ~ Four wipe samples were collected. The four wipe samples evidenced MMVF above the detection limit, which indicates that MMVF was present prior to cleaning.
Post P' Cleaning Samples - Three air samples and five wipe samples were collected after the first cleaning. All of the air sample results indicate that MMVF was present, but at levels below the primary clearance criterion of 10 S/L. All of the wipe sample results were in the range of 114.46 S/cm^ to 228.93 S/cm^. This indicates that the cleaning method was able to reduce the pre-cleaning concentration of MMVF.
PAH Before Cleaning Samples - Four wipe samples were collected. All four samples were below the detection limit, and the TEF of 300 pg/m^.
Post P' Cleaning Samples - Four wipe samples were collected. All four samples were below the detection limit; the TEF value was below the primary clearance criterion of
