The reference is to some changes and additions I requested for the last draft of the report.
---- Original Message---- From: Benjamin M. Sallemi [mailto:[email protected]] Sent: Tuesday, December 24,2002 9:02 AM To: Penny Theodorellys Subject: Corrected Dioxin Reports
Penny,
Following are the corrected Excel reports for the Dioxin "post test" wipe samples for 125 Cedar Street. The TEQ (or TEF, as referenced in the spreadsheet) results have been corrected to include 50% of the non detects, and also reported with units of ng/m2.
I will finalize your comments on the final report after the X-mass holiday. I'm waiting for verbage from our lab about the analytical procedures taken for the various types of analysis performed (i.e., PAH, Dioxin. Mercury, etc.)
Have a great holiday.
