Subject:
Subsurface Investigation for Suitability of
On-Site Sewer, Lot 16, Block 4, Valley Vue
Estates #2
Dear Mr. Lutje:
Transmitted herein in accordance with your instructions are
the results of the above referenced investigation as performed
by us on June 16 and 18, 1977. The scope of this project is
investigation for suitability of an on-site sewerage system.
Included in this transmittal are:
Test Hole Location Sketch
Test Hole Log
Explanatory Information
Figure 1
Table A
Sheets 1-3
The exploration was conducted using a Nodwell mounted ~4obile
Drill Model B-50 drill rig with a continuous flight solid
stem auger. The rig is owned and operated by Denali Drilling,
Inc. Drilling was supervised, the test holes logged and
percolation test performed by ~. Terry L. Barber, Geologist
with Alaska Testlab.
The test hole was placed at the approximate location shown
on Figure 1. The log of this test hole is included as
Table A of this report. Zn interpreting the log it would be
helpful to utilize the explanatory information contained in
Sheets 1 to 3 of this report.
When drilling was completed a 3/4" slotted PVC pipe was
inserted in 'the hole to aid in determining the free water
level. For the percolation test, the test hole was filled
with water and left overnight to saturate. On returning the
next day, the hole was refilled with water and the drop in
the water level carefully monitored over the next 60 minutes.
This procedure is not a standardized percolation test,
however, we understand that the Municipality of Anchorage,
Department of Public Health and Environmental Protection
.prefers tests performed in this manner to evaluate a site
for a proposed on-site sewerage system.

Using the above test, the observed minimum percolation rate
was 40.0 minutes per inch.
No water table was observed during drilling,
be noted that the free water level normally
seasonally and with precipitation.
but it should
fluctuates
We hope this report meets your present needs. If we can be
of further service, please feel free to contact us.
Sincerely,
ALASKA TESTLAB
