Abstract
In response to a request from the State of Mew Mexico Occupational Health and Safety Bureau, a 1 year follow up test was conducted at the New Mexico State Highway Department General Office Building and Annex (SIC-9199) in Santa Fe, New Mexico, which had been contaminated with polychlorinated-biphenyls (1336363) (PCBs), polychlorinated dibenzofurans and polychlorinated dibenzo-p-dioxins during a transformer fire. After substantial work, the building had been declared safe for reoccupancy. The investigation was intended to determine whether significant changes had occurred since the building was reopened. Two air samples were collected in the intake vents for the building and showed no evidence of PCB contamination from the outside air. Of the 23 samples collected inside the building in the various workspaces, three from the basement of the building showed detectable concentrations of PCBs ranging from 0.028 to 0.15 micrograms/cubic meter (microg/m3). During the sampling period, all the building's heating, ventilation, and air conditioning systems were operating under normal occupancy conditions. All the concentrations were therefore significantly below the reoccupancy criteria of 0.4microg/m3. The author concludes that the buildings are safe for occupancy, and further environmental testing will not be necessary.
