2) Provide Sampling and Cleaning for Residences Upon Request
Based on the extensive outdoor sampling efforts, demonstrating that the source of contamination
has diminished (e.g. the fires are out, plume mapping), the Indoor Air Working Group comprised
of representatives from New York City (DOH, DEP), New York State (DOH) and EPA, does not
believe that door-to-door sampling and cleaning would be a cost effective method of addressing
current residential concerns. As one of a number of alternatives, we are offering sampling and
cleanup (or oversight of cleanup) to residences based on some screening criteria (e.g., was prior
sampling conducted, has the residence been cleaned according to recommended NYCDOH
procedures).
Based on the 2000 Consensus, there are approximately 11,000 residences in a 10 block radius of
the WTC.. We are still trying to determine the number of employees in the 10-block radius.
Costs for sampling and cleaning of the public schools within the vicinity of the WTC were not
included. The Board of Education has been conducting extensive sampling of the 7 affected
schools (i.e., P.S. 150, P.S. 234 and PS and IS 89,100 Trinity Place, 90 Trinity Place, and
Stuyvesant.) since each school was abated by New York City’s School Construction Authority,
Cleaning included: washing exteriors, wet wiping, HEPA vacuuming, and abating ventilation
systems. (Costs for cleaning the outside of ALL buildings is not included, since NYCDEP is----
handling this matter.
Range of Sampling Coste - 1,000 Residences to 11,000 Residences
$5 Million to $55 Million
Range of Cleanup Coste - Assume one-half of the residences would require cleanup
$2.5 Million to $25 Million
Costs for Commercial Sampling and Cleanup - TBD
3) Establish a Permanent Information Clearinghouse (Communications Task Force)
Provide detailed cleaning procedures (need to be developed)
Develop a database of all residential sampling (estimates of up to 100,000 sample
analyses have been provided to NYCDEP)
Establish an office (i.e.-, 2 full time equivalents) to respond to community and query
database (through debris cleanup)
Estimated Costs: $700,000
4) Establish a Scientific Panel to Address Risk and Cleanup Issues
Estimated Coste: $1M to $2M over 2 years
