Gentlemen:
In r~sponse to your request we have placed a
series of test holes to depths of from 15' to 25' (depending
on soil types), examined the soils, p~[formed a limited number~
of percolation type field tests and formulated an opinion
with regard to permeability of the various soils.
The soils' permeability, as expected, appears to
be related to the soil's natural structure as well as to
grain size. Reasonably high rates of acceptance developed,
with more than 4~r being the rule between a depth
of 20' to 2b', usually more than 4" between 15' and 20',
and often more than 4" between 0' and 15'. The rate of
"percolation" is in each case a function of head with the
starting head being ground surface, the ending head in some
instance being deep, i.e., 5' to 12'.
In all cases the soils examined were those least
expected to percolate --- silts.
The percolation rates based on our opinion of the
soils and the several tests are as follows:

The exploration was accomplished with a Mobile B-50
drill mounted on a Nodwell Tracked vehicle and a backhoe.
The drill and crew were provided by Denali Drilling; hole
logging, field and laboratory tests by staff; supervision and
review by O. Hatch and the writer.
The program was separated into two phases. Phase I
included the bulk of the test holes and laboratory review
and some percolation data. Soil stratification was the major
natural detail investigated. Stratification exists in large
units with few thin seams of soil.
Consideration of permeability characteristics
by laboratory and field methods was made, and it was
elected to use field methods, as the formations were of
sufficient verticle extent to accept relatively unsophisticated
determination --- Phase II.
Generally the field determinations of permeability
followed the FHA method, except that the head was varied to
as much as full depth of the hole (15' to 25') to simulate
deep trench infiltration galleries. The computed flow,
however, was generally restricted to the bottom of the hole
and for conservative estimates may be assumed to be an 8"
hole of usually less than 5' depth (last reading). The
surrounding soils were more or less saturated as all of the
tests were continued for more than 24 hours (generally 4
to 6 days). Also, "percolations" seemed to be stable to
increasing with time. Several 15' open hole tests were
of limited reliability due to sloughing, which reduces the
computed percolation rate.
It is our opinion, based on these data, that the
fine grained soils (majority) should perform well, provided
the inserted liquid is water with a low to nil volume of
solids and other organic debris, as we expect the deeper
soils to have little ability to support biodegradation.
Thusl while percolation rate/permeability is satisfactory
to simple on-site systems --- individual package plants
are thought to be prudent.
Soils Described
The deposit consists of a glacial moraine till.
Eratic boulders are found to exist.in fair numbers in Block 5
(lots 5-11 contains a surface exposed boulder about 10'
in diameter).
Tryck, Nyman & Hayes
4 December 9, 1974
Subsurface soils predominate in soils and fine sands
with locally varying amounts of coarser sands, gravel, cobbles,
and boulders. Silt free and low silt content soils exist
on the site, but not in substantial quantities. Layers
of low-silt and silt free sands and gravels less than 2'
in thickness appear to exist only as local pockets, not as
consistent layers. Those layers which are more than 2'
in thickness seem to tend toward being consistent layers.
Even these small pockets of less than 2' in thickness,
though, will increase the surface area of exposure to water
flow.
A close relationship between silt and fine sand
exists and may be evidenced by an unusual number (13%) of
samples which fall into a classificaton of being F-4 but SM.
It may be this characteristic of composition accounts
for a greater rate of percolation than would be normally
anticipated from a basically"sil~ soil.
In general the soil conditions relative to percolation
do no% improve below 15' This would tend to indicate that
increasing the depth of a disposal system would not be advantageous
unless an increased wall surface exposure were necessary in
order to fit the system within the prescribed area of a lot.
Those lots which might benefit from a system deeper than 15' to
attain better soils are 3-30, 5-8 through 11, 5-14, and 6-3
through 7. It is believed at this time that percolation
rates on s0J~s_in the top 15' will be adequate for disposal
systems on all lots. It is ~lso believed that percolation
from the systems will be at a rate great enough so as not
to saturate the general area.
