Subsurface Study for On-Site Sewer Feasibility
Dear Mr. Straight:
As per your request, we observed the test pit that you had
dug at the planned location of your septic tank on the above
referenced property. The test pit was located approximately
70 feet NW of the NW corner of the existing house. The test
pit was logged and its soils visually classified by Mr. O.M.
Hatch, senior technician/staff geologist with our firm. The
results of this procedure are included in Table A .... the test
pit log. Sheets 1--3 are stand.ard explanatory information
included to help you in interpretation of the data presented
in the test pit log.
The test pit was logged on July 30, 1975. At that time
water was standing in the pit at a depth of 8 feet below the
ground surface. The exposed soil strata from 2 feet to 8-
[[/2 feet was a slightly Silty Gravelly Sand with a unified
classification of SP/SM ~nd a variable silt content from 5-
15% by weight. On visual inspection, the required absorption
area per bedroom for a septic tank placed in this soil would
be no more than 200 square feet.
When the test pit was initially dug, the water was at a
level 6 feet below the ground surface and receded to 8 feet
.by the time the hole was logged. The lot is on a NW facing
hill and it appears that some of the water in the test pit
was surface water trapped by thawing frost. We would
recommend that you leave the pit open for a time and inspect
it at a date later in the su~er.

Dear Mr. Straight:
As requested by yourself and required by the Department of
EnvirOnmental Quality of the Greater Anchorage Area Borough,
we inspected the test pit located on the above referenced
property which we had logged on July 30, 1975 and is referenced
in our letter to you of August 8, 1975. The pit was in-
spected by Mr. O.M. Hatch, senior technician/staff geologist.
with our firm on August 15, 1975 and there was no water in
the test pit on that date. This confirms our opinion,
expressed in our previous letter, that the water in the pit
was trapped water from melting frost and not the actual
ground water level.
We hope that this information is sufficient to your needs.
If we can be of further service please do not hesitate to
contact us.
Very truly yours,
ALASKA TESTLAB
