Gentlemen:
Transmitted herein in accordance with your instructions are
the results of the above referenced investigation as performed
by us on Hay 6 and 7, ~977. The scope of this project is
investigation for suitability of an on-site sewerage system.
Included in this transmittal are:

Sheets 1-3
The exploration was conducted usJng a Nodwell mounted .Mobile
Drill Hodel B-50 drill rig with a continuous flight solid
s/em auger. The rig is owned and operated by Dena!i Drilling
Drilling was suoervised, the test holes logged and percolation
test perfermed by Mr. O.H. Hatch, Geelegist with Alaska
Tes flab.
The test holes were placed at the approximate locations
shown en Figure '1. The legs of the test heles are included
in Table A of this report. In interpreting the leg, it
would be helpful to uhilize the explanatory information
contained in SteeLs 1 te 3 of this report.
When drilling w~'~s completed, 3/4" slothed PVC pipe was
inserted in 'tile holes to aid in determinincj the free water
level. For the percolation 'Lest, the test heles were filled
with water and left evernight te saturate. On the fo!lewing
day, the heles were 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 Hunicipality 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 rates
were 11.1 min./inch for Lot lA, Kelly Subdivision, and 3.3
min./inch for Lot lA Reilly Subdivision.
NO water 'table was observed during drilling, but it should
be noted that the free wa'her level normally fluctuates
seasonally and with precipitation.
We hope this report meets your present needs. If we can be
of further service, please feel free to contact us.
Sincerely,
ALASKA TESTLAB
