RE: World Trade Center Dewatering Contract No. 20020004649 MTA Job 01-4906 Water Analyses
Dear Brian:
Attached find complete results of the analysis of the water samples taken from the WTC site on April 22, 2002. MTBE level for the sump discharge (B-6 30 hp sump pump) was 32 ppb and for the dewatering wells (Main Discharge) was 2.0 ppb.
Chlorddifluoromethane was 180 ppb in the sump discharge and 8.4 ppb in the dewatering well discharge.
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.
Very truly yours, MORETRENCH AMERICAN CORPORATION
