Subsurface Investigation for Suitability Of On-Site
Sewage Disposal, Lots 3, 6, 8, 10, 13, 22, 24, 25,
28, and 31/32; Tract B, Spring Forest Subdivision
(Forsythe Property)
Dear Mr. Cange:
Test Holes were drilled on the subject lots to determine sub-
soil conditions and to determine suitability for on-site sewage
disposal. Transmitted herein are the soil logs for the test
holes with accompanying laboratory testing, and results of per-
colation tests run in these holes. Also attached is a test
hole location sketch. The locations shown are approximate.
They were located using topographic features and by pacing
distances. We recommend strongly that they be located by sur-
vey as soon as possible to avoid confusion later.
The test holes were drilled on April 21 and 22, 1981, using a
Nodwell mounted, Mobile B-50 drill fitted with a solid flight
auger. The drill rig is owned and operated by Denali Drilling,
Inc. The drilling was supervised and the test holes were
logged by Mr. O.H. Hatch, geologist with Alaska Testlab. Grab
samples were obtained at five foot intervals in each test hole,
were visually' identified, and were sealed in plastic bags to
preserve the natural moisture content. After drilling, a per-
forated, 3/4 inch PVC pipe was placed in each test hole to
monitor water table elevations and to run the percolation test.'
The percolation tests were performed by filling the test holes
with water and allowing them to saturate. The following day,
the holes were refilled with water, and the elevations of water
in the holes were measurd at 10 minute intervals for a one hour
period. The percolation rate given in this report was computed
using the rainimum 20 minute absorption recorded i.n the percola-
tion test. The following table lists the measured percolation
rates.

The measured percolation rates
in ~est Holes 1, 3, 5, and 8
were actually less than 10.0 minutes/inch; however, we recom-
mend using this more conservative value due to the silty nature
of ~he soil. A perc test was not run in Test Hole 10, because
the high water (less than one foot) makes this area unsuitable
for on-site sewage disposal.
Disposal systems should be placed between 5 and 12 feet below
the surface except for Lots 31 and 32 where the systems should
be kept as shallow as possible to maintain'the necessary separ-
ation from the seasonal high ground water level.
If you have any questions regarding these tests, please feel
free to call.
Very truly yours,
