DEP has been working with the involved City agencies, including the Board of Education, to provide air monitoring in and around the schpeds near the World Trade Center disaster site. DEP is collecting 8 hour ambient air samples that are analyzed for asbestos at four locations. These locations are outside of the main entrances to: Stuyvesant High School, IS/PS 89, PS 234 and the High School of Economics and Finance. DEP began sampling on October 4, 2001. From October 4th through October 18th, DEP only did a TEM analysis if the PCM concentration was above 0.01 fibers per cubic centimeter (f/cc). During this period of time, there was only one reading above 0.01 f/cc. The TEM result was below the Asbestos Hazard Emergency Response Act (AHERA) standard of 70 structures per square millimeter (s/sqmm). As of October 19, DEP began conducting a TEM analysis on all samples to provide a direct comparison to the AHERA standard. Of the 356 samples that have been collected between October 19 and January 15, 2002, all have been well below the AHERA standard of 70 s/sqmm. Since that period, the results continue to be well below the AHERA standard.
