Subject: Permit Expiration
Dear Sir ~.
A permit issued by this department for well and/or on-site
sewer installation on Parcel B of Lots 50, 51, and 52
Alaska Railroad Reserve Lease has expired since the issue
date exceeds one (1) year.
In the event you still plan to install the well an~/or on-site
sewer system, a new permit is required. The oriqinal soil
test may be used to obtain a current pe~it.
If the well has been drilled, a well loq should be s~t to
this department to document the installation date.
If you l~ve ~y questions regarding the a?~ve matter, please
do not hesitate to contact this offic~ i~e~iately at 264-
4720.
Sincerely,
Les N. Buchholz,
Sanitarian

Subsurface Investigation for Suitability of
On-Site Sewer; Lots 50, 51, 52
Gentlemen:
Transmitted herein in accordance with your instructions are
the results of the above referenced investigation as performed
by us on October 9, 1976. The scope of this project is investigation
for suitability of an on-site sewerage system.
Included in this transmittal are:

Exu!anatorv information

Table A
Sheets i-3
The exploration was conducted using a Mobile 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 Mr. O.M. Hatch, 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. In interpreting the log it would be helpful
to utilize the explanatory information contained in Sheets 1
to 3 of this report.
The water table was observed at 4.0' during drilling, but
it should be noted that the free water level ncrma!ly 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.

Test Hole Log - Description Guide
The soil descriptions shown on the logs are the best estimate of the soil's
characteristics at the time of field examination and as such do not achieve the
precision of a laboratory testing procedure. If the log includes soils samples,
those samples receive an independent textural classification in the laboratory
to verify the field examination.
The logs often include the following items:
Depth Interval - usually shown to 0.1 foot, within that zone no
significant change m soil type was observed through drill action, direct
observation or sampling.
Frost Classification - NFS, FI, F2, F3, F4, see "Soil Classification
Chart"
Texture of Soil - An engineering classification of the soils by particle
size and proportion, see "Soil Classification Chart", note the
proportions are approximate and modifications to the soil group due to
stratification, inclusions and changes in properties are included.
Moisture Content - this is a qualitative measure: dry, no or little apparent surface moisture,
.damp, moisture forms portion of color, less than plastic limit,
wet, no free water, often soft. if cohesive soil,
saturated, free water ma.',' be squeezed out, if a free draining soil;
dilatent at natural moisture content, if a non-plastic silt or fine
LW, NP, M% or dflatency.)
Density ~ refers to more-or-less non-cohesive soils, such as sand gravel
mixt~es with or without a fine fraction, derived from drilling action
and/or ~mple data; usually described as: very loose, loose, medium
dense, very dense. General intent is to portray earthwork
characteristics.
Stiffness - refers to more-or-less cohesive soils and fine grained silts of
the clay-silt groups. Derived from drill action and/or sample data. Very
soft, soft, stiff, very stiff and hard are commonly used terms.
Particle size - The largest particle recovered by the split spoon is
1-318", Shelby tube Y', auger flights (minute-man) 2", Auger flights
(B-50 hollow stem) 6"-8". Larger particles are described ind~ectly by
action of the dr~ling and are referred to as cobbles, 3" to 8", or
boulders 8"+. Therefore when reviewing the gradation sheets, if any,
the description on the hole log must be considered for an indication of
larger particles.
Unified Soil Classification - This is a two letter code. See Unified
Classification sheet (or f~ther definition. In some cases AASHO and/or
FAA soil classifications may be shown as well as the unified.
Atterberg Limits - useful for fine grained and other plastic so~s.
PI; nat~al moisture content believed to be less than plastic limit
PI+; nat~al moisture content believed to be between plastic and liquid
limits
L__~w+; natural moisture content believed to be greater than liquid limit
NP; non-plastic, useful as a ~nodifying description of some silty
~aterials.
Dilatency - is the ability of water to migrate to the surface of a
saturated or nearly saturatcd soil sample when vibrated or johed - used
as an aid to determine it' a fine grained soil is a slightly or non-plastic
silt or a volcanic ash.
Rock flour -- finely ground soil that is not plastic but otherwise appears
~ clayey silt.
Organic Content - usually described as Peat, PT, sometimes includes
discrete particles such as wood, coal, etc. as a modifier to an inorganic
soil. Quantity described as; trace, or an estimate of volume, or, in case
of all organic, - as Peat. This may include tundra, muskeg and bog
material.
Muck -- a modifier used to describe very soft, semi-organic deposits
us--'~Tl]y occuring below a peat deposit.
Amorphus peat - organic particles nearly or fully disintegrated.
Fibrous Peat -- organic particles more-or-less intact.
Bottom of Testhole -- includes last sample interval.
Fro~t I ine -- ~ea~ona! f'ro~r denth at detr~ihed h¥ d~iilir~g action anriior
samples at the time of drilling.
Frozen Ground - other than frost line, described by samples, usually
includes description of ice content, often will include modified Unified
Classification for frozen soils - this is a special case related to
permafrost studies.
Free Water Level - The free water level noted during drilling. This is
not necessarily the static water table ;it the time of drilling or at other
seasons. Static water table determination m other than very permeable
soils requires observation wells or piezometer installations, used only m
special cases.
Blow/6" - The number of blows ~fa 140 weight free falling 30" to
advance a 2" split spoon 6"; the number of blows for a 12" advance is,
by definition, the standard penetration.
,41% - natural moisture content of the soil sample, usually not
performed on clean sands or gravels below the water table.
Type of Sample -
SP, refers to 2" split spoon driven into the soil by 140 pound
weight, a disturbed sample,
S, thin wall tube, "Shelby" used to obtain undisturbed samples
of fine grained soil,
G, "grab" disturbed sample from auger flights or wail of trench,
C, cut sample, undisturbed sample from wall of trench.
Dry Strength - a useful indicator of a soil's clayey fraction, N=None,
L=Low, M=Medium, H=High
Group - The samples are placed into apparently similar groups based
on color and texture and ;ire arbitrarily assigned a group letter. Further
disturbed tests including Atterberg Limits, grain size, moisture-density
relationship, etc. may be perfor~ned on the group and are assumed to
reflect the general distrubcd characteristics of the soils assigned to the
group. This is an important phase of the soil analysis and is used to
standardize the variou~ qualitative determinations and to reduce the
number of quantitative tests necessary to describe the soil mass.
