RE: 
Comprehensive Groundwater Sampling Event
Tutu Wells Site
St. Thomas, LJ. S. Virgin Islands
Dear Ms. Kwan,
On behalf of the Tutu Environmental Investigation Committee (TEIC), de maximis, inc.
is submitting for EPA review and approval the enclosed list of those monitoring and
supply wells proposed to be sampled by Geraghty & Miller during the Comprehensive
Groundwater Sampling Event (Task 10) of the Phase II Remedial Investigation.
The Comprehensive Groundwater Sampling Event is scheduled to begin on May 16
and will continue through mid-June. As we discussed during the April 28, 1994
conference call, TEIC has requested EPA and DPNR assistance in obtaining access to
some of the supply wells proposed for sampling under this event (Harthman II and III,
Matthias, Gassett, and Harvey). We anticipate the successful acquisition of access
permits from other well owners.
Finally, it is proposed that samples from the supply wells will be analyzed for TCL
Volatiles in accordance with the CLP SOW (March, 1990) as opposed to EPA Method
524.2 which was previously used. 
Therefore, all groundwater samples will be
analyzed for those parameters indicated in the Phase II Rl Work Plan in accordance
with the project QAPP.
Please contact either me or Jack McBurney with any questions regarding this
proposal. We appreciate your prompt review and assistance.
Sincerely,
de maximis, inc.
