Dear Mr. Pace:
During March and April of 1981,. we drilled a 15 foot boring on
each of the above lots and placed a perforated, 3/4 inch PVC pipe
in each hole rio that the water table could be monitored over a
period of time and a percolation test run in the hole. The holes
were drilled using a Nodwell mounted, Mobile BS0 drill rig owned
and operated by Denali Drilling, Inc. The drilling was supervised
and the test holes logged by Mr. Ted Krupka, senior technician,
and Mr. O.M. ~atch, geologist with Alaska. Testlab.
After the holes were drilled, our technician ~eturned on several
occasions and checked the water level in each of the test holes.
After a period of time the holes~were~~'~>left to stand
overnight, saturated again and a perco/~t~on'"'t~'~t run. The
percolation test was run by monitoring the drop in the water
table elevation at 10 minute intervals for a minimum of one hour.
The percolation rate listed in this report was computed using the
slowest 20 minutes 'of that percolation test.
Included with this report is a test hole location sketch for each
lot and a log of the boring placed on each lot.
The results of this exploration are described as follows:
Lot 4, Block 1
The water table elevation measured in the test hole at this site
remained fairly constant at about 12 feet. The percolation rate
measured on April 15 was 6.0 minutes/inch. Because of the need
to keep the system shallow and ~he high silt content, we recommend
a more conservative design percolation rate of 10.0 minutes/inch.
Second and Fourth Anchorage
Limited Partnership
.April 17, 1981

rate was 5.2 minutes/inch, however, we recommend a design rate of
10.0 minutes/inch. Since the seasonal water level is quite high,
we recommend a mounded disposal system so sufficient separation
is achieved.
Lot 10, Block 2
The test hole was located in the southwest corner of the lot, and
we recommend that the sewage disposal system be placed in this
area. The water level is quite near the surface towards the
front of the lot. The water level while drilling on April 8 was
9.0 feet, then was found at about 12 feet over the next few days.
On April 14, the percolation rate was measured at 2.5 minutes/inch.
We recommend that a more conservative rate. of 10.0 minutes/inch
be used, due to'~the silty nature of the upper soils. The system
should be placed as ~igh as possible, in the upper 8 to 10 feet,
to avoid conflicts with the seasonal high water, mounding may be
necessary for insulation.
Lot 17, Block 2
No ground water was encountered while drilling on this lot on
April 8, or when checked again April 9 and April 16. The measured
percolation rate was 5.4 minutes/inch, however, we recommend a
more conservative design rate of 10.0 minutes/inch because of the
siltier nature of the soils.
Lot 19, Block 2
No water table was observed in the 16 foot test hole while drilling
on April 8, or on April 9. The percolation rate was measured at
8.9 minutes/inch, however, we recommend a more conservative
design rate of 10.0 minutes/inch because of the silty nature of
the soils. The system should be placed as high as possible, as
high seasonal water levels were found.in the immediate area.
Lot 26, Block 2
~he test hole was drilled near the center of the lot April 8, and
no water was observed. The test hole was also found dry April 9..
The measured percolation rate was 6.2 minutes/inch.
Lot 3, Block 4
No water was observed in the test hole at this site while drilling
on April 8, bu~ was at 12.5 feet the following day. The measured
percolation rate was 14.6 minutes/inch. The disposal system
should be kept as high as possible to avoid conflicts with the

checked April '9. The measured percolation rate was 4.0 minutes/inch.
We recommend a more conservative rate of 10.0 minutes/inch be
used, since the upper soil is silt.
