NYC 9/11 Public Portal Document

****DRAFT Version 10, October 29, 2001****

XI. Screening Guidelines/Recommendations:

The remaining pages of this document are draft, public health-based screening guidelines that are being developed for use in interpreting the results of the sampling effort. If contaminants are below screening guidelines, further health evaluation of the data is not necessary. If guidelines are exceeded, additional review of the data and the sample collection circumstances is necessary. If a guideline is exceeded, it does not automatically indicate that a health concern exists.

Note: these guidelines are undergoing review and comment-they have not been updated from the previous version of this document
