RE: World Trade Center Dewatering Contract No. 20020004649 MTA Job 01-4906 Water Analyses - Sump & Dewatering Wells
Dear Brian:
Attached find results of the analysis of the water samples taken from the WTC site on June 24. 2002. MTBE level for the sump discharge (B-6 30 hp sump pump) was 49 ppb and for the dewatering wells was 2.4.
Chlorodifluoromethane was 60 ppb in the sump discharge and 5.8 in the dewatering wells.
We are also forwarding a copy of the tables which track MTBE and Chlorodifluoromethane concentrations for all of the water sample testing which has been performed on the site.
Asbestos results are also included. Dioxin results will be forwarded upon Moretrench’s receipt of same.
Very truly yours, MORETRENCH AMERICAN CORPORATION
