NOTES: MMVF - Man Made Vitreous Fibers Bulk samples for HVAC or window AC inits will be collected and analyzed for all parameters if sufficient volume is available. If volume is not sufficient analysis will be performed for asbestos only. This table does not include the 10% Quality Control samples. Total Number Of Samples Samples will be collected from 14 buildings. 3 units within each building (2 residences and 1 common area). 14 buildings x 3 units per building = 42 units
38 samples/unit x 42 units = 1596 samples + 160 QC samples = 1756 samples
