RE: Test Hole and Soil Log Report for Sanitary System
Eastern Portion~ N~, SE%, SE¼, Section 18,
T12N, R3W, Seward Me, dian, Anchorage Alaska
Dear Mr. Mercer:
We are submitting herewith the test boring results and our comments
regarding soil conditions encountered at the subject site. This in-
vestigation was performed in accordance with your request of October 12,
1976, and those procedures outlined in a letter dated July 15, 1975, by
Mr. Rolf Strickland of the Muncipality of Anchorage Department of
Environmental Quality.
Three test holes were bored within the subject site area for the purpose
of defining general subsurface soil conditions for the proposed sanitary
system. Drilling was accomplished with an auger type drilling rig. Test
Hole 1 was drilled to a total depth of 19 feet; Test Hole 2 to 9 feet,
where auger refusal on a boulder was encountered; and Test Hole 3 to
18.5 feet. The final log prepared for the test holes has been included
in Drawing A-02 and A-03.
Groundwater was not encountered in the test holes while drilling.
In Test Hole 3, a percolation test was performed from a depth indicated
and reflects average infiltration from that depth to the bottom of the
hole.
We appreciate being given this opportunity to be of service to you.
Should you have any questions with regard to the above, please do not
hesitate to contact us.
Very truly yours,
R & M CONSULTANTS, INC.
