Re: Western Auto Site Investigation-December.7-11, 1992.
Dear Sir,
j
I 
am submitting 
another report 
on 
the 
continuing site
investigation on the location of suspected underground tanks
formerly operated by the Western Auto Store located at Four Winds
Plaza, #392. Anna's Retreat, 
St Thomas. 
Following your
suggestion, I continued the effort to locate and determine the
size and orientation of the LIST 
near the Western Auto repair
bays. U'e also drilled three more test holes around the ramp near
the northwest corner of the area.
The site investigation proceeded utilizing similar investigative
methods and quality control/quality assurance as described in my
letter of Nov. 23, 1992:
1. 7W-6: Located 11 ft east and 2.75 ft. south of the northwest
corner of the area (east side of ramp) Drilled to refusal at 14
inches. A cement and asphalt cap nine inches deep was followed
by a soft red clay. 
A hard cement floor was found below this
point. Samples were taken of the clay for TRPH, oil and grease,
and SPA analyses 8O1O, 802O and S100.
^. TUj-7: 
Located 15 ft. south and 6.5 ft. east of the northwest
corner (southeast corner -of ramp). 
Grilled to refusal at 12
inches. Cement and asphalt was followed by the same concrete
pad .
3. TW-8: 
Located 3.8 ft. south of the northwest corner (west
side of ramp). 
Drilled to refusal at 11 inches. 
A similar
concrete and asphalt cap was 
found with the 
hard concrete pad
below .
appears to be a thick concrete pad that extends under the
r*rop. 
it was 
extremely hard and was encountered at the same
G*Pth below land surface at ail three sites. 
I am awaiting
s^dl/sis of the sample at TU-6 .

Tank 82: A stiff metal snake was used to determine the size and
orientation of the tank. The probe was inserted into the tank
and rotated until resistance was encountered. 
The tank appears
to be cylindrical, approximately 3 ft. in diameter and 5-6 ft.
long. 
The tank is 
parallel to 
the bays 
(south-north
orientation ).
