Dear Ma, Kwan:
As we arc nearing the completion of the drilling program for the above-referenced
project, Gcraghty & Miller, Inc. has projected the following schedule (see Table 1) for well
development, ground-water sampling, and aquifer testing of the recently installed monitoring
wells. This schedule is dependent upon development of all 18 monitoring wells by no later than
September 21, 1992.
If you have any questions, please call.
Sincerely,
GERAGHTY & MILLER, INC.
