RE: Water Quality Testing
PATH Tunnel/WTC Dewatering
Moretrench Job #01 <4906
Gentlemen:
This is to confirm that we have received a copy of the NYDEP letter dated February 20, 2002
regarding the required analysis for the dewatering and sumping discharges at the World Trade
Center site. Beginning with the sample that was collected on March 1, we have instructed the
testing laboratory to include the analysis for PCB’s chlorodifluoromethane, dioxins and
asbestos.
As we discussed with you, we have instructed the laboratory to analyze for PCB’s using EPA
method 608 in accordance with the DEP letter. However, we have been notified by the lab
(Severn Trent Labs) that the results for this method are only reported in parts per billion (ppb).
Please advise If you wish us to change from the method 608 analysis which we have instructed
STL to use.
Also, we have advised STL to perform the required analysis for chlorodifluoromethane, a
substance which has been detected in screening the samples. The lab is not aware of a test for
chlorofluoromethane. See the attached letter from Severn Trent Services dated 3/6/02.
In accordance with your direction at our meeting of March 5“’, we will collect water samples for
analysis once per week until we receive further direction from you.
Very truly yours,
MORETRENCH AMERICAN CORPORATION
