Water Analyses
Dear Brian:
Attached find results of the analysis of the water samples taken from the WTC site on May
22, 2002. MTBE level for the sump discharge {B-6 30 hp sump pump) was 49 ppb and for
the dewatering wells (Main Discharge) was 2.1 ppb.
Chlorodifluoromethane was 74 ppb in the sump discharge and 12 ppb in the dewatering well
discharge.
We are also fonvarding 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,
MORETREI IPORATION
