School Monitoring Data

DEP worked with the involved City agencies, including the Board of Education, to provide air monitoring in and around the schools near the World Trade Center disaster site DEP collected 8 hour ambient air samples that were analyzed for asbestos at four locations. These locations were outside of the main entrances to; Stuyvesant High School, IS/PS 89, PS 234 and the High School of Economics and Fmance. DEP began sampling on October 4, 2001, and completed sampling on June 30,2002. From October 4th through October 18th, DEP only did a TEM analysis if the PCM concentration was above 0.01 fibers per cubic centimeter (fZee). During this period of time, there was only one readmg 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. Between October 19 and June 30,2002, all samples were well below the AHERA standard of 70 s/sqnun
