Recommendations for this site include the possible use of mound systems designed to overcome limitations of a
high level of seasonal soil saturation and slow permeability present in the subsoil. A soil saturation determination
pursuant to Comm 85.60 must be completed by a CST and approved by the department to certify that this site
has at least 6 inches of soil free of saturated conditions for seven or more consecutive days. Should a mound
design be pursued for use at this site, the linear loadin rate should not exceed 4.0
wastewater a rated should not exce st 30 inches of sand lift must be used when
applying septic tank effluent to the distribution cell. The longest portion of the mound must be orientated along
the contour. The mound shall be constructed to divert surface water around the mound structure as much as
possible.
Other considerations:
1. On slopes< 3% down slope basal area should be increased to prevent toe seepage.
2. Chisel plowing to 12-16 inches depth is recommended to improve percolation.
3. System locations are set at specific locations and those areas should be protected from damage during
site development and building construction.

An onsite soils verification was conducted at the above referenced site as per district policy for all sites with less
than four inches of unsaturated soil below the bottom of the A horizon. The intent of this investigation is to
confirm initial observations by the certified soil tester(CST) relating to the presence or absence of redoximorphic
features in the A horizon and subsoil. In-situ soil texture, structure, and consistence factors were also reviewed
as they h y relate to wastewater application rates. Other site conditions such as percent and direction of slope,
landscape position, land surface contour length, and surface water hydrology may also be noted and their effects
are factors considered in the recommendations and conclusions portion of this report.
This parcel will be divided into five lots by a CSM. This report applies to specific areas and not to the entire area
of each proposed lot. Lot specific reports will be submitted by the CST as interpretative determinations at a later
date.
This parcel has not been farmed for several years and is over grown with grass and weeds. During the
preliminary investigation on June 10, 2003, with CST Tom Nelson, it was noted that many areas of the parcel had
been disturbed, possibly by logging, and this made soil interpretive evaluations more difficult. Efforts should be
made to avoid disturbed areas for detailed soil evaluations in the upper 12 inches of the soil profile.
Nevertheless several typical soil profiles can be described

The plan approval expiration date on your copy of the approval letter dated.July
21, 2003, does not apply to the interpretative determination. The approval is
good until or unless conditions change as stated in stipulation number 7 of the
approval letter.
The-department will accept the interpretative determination approval as the basis
for a mound system design and the county should accept both the interpretative
approval and a mound system approval as adequate documentation for sanitary
permit issuance.
Keep in mind however, that should the standards for mound design change this
could affect initial approvals for such a system. Both the state and county issue
approvals and permits based in the rules in effect at the time of review or permit
issuance. Once a sanitary permit is issued for a project it is locked into the rules
in effect on the date ,of approval even if new, more restrictive rules take effect.
Therefore, it is often advisable to obtain the sanitary permit well in advance of a
project to ensure that the system can be constructed as planned. The sanitary
permit has a two year life and can be renewed for like periods as long as code
requirements do not change that affect the design.
If you have any further questions regarding this matter, please feel free to
contact me.

Proper owner: Kurt and Elizabeth Christensen ;F
Legal Description: NW NE 07 29 15W C'
Springfield, St. Croix County
INTRODUCTION
On 27 June 2003, a soil test and evaluation was conducted by this soil tester on the property
described above. The soil test was done in response to a request by the property owner,
Elizabeth Christensen,as part of the development of this parcel for residences. It is the intention
of the property owners, Kurt and Elizabeth Christensen,to subdivide this land and sell parcels.
Initially,there are 5 parcels that have been surveyed. Additional parcels will follow.
The initial determination found the sites to be marginally suitable for mound type septic systems
(Soil Absorption System). However,there was not a clear separation distance of 4 inches
between the bottom of the A horizon and evidence of seasonal saturation(as evidenced by
redoximorphic features). As a result,this soil tester requested the presence of the Wisconsin
State Waste Water Specialist, Leroy Jansky,to conduct a soils review of this site, specifically in
the area of the proposed SAS's. My Jansky had previously visited the site at the request of a soil
tester who had done preliminary borings and field assessments on the site. The soils verification-
soils on-site was conducted on 4 July 2003.
GEOLOGICAL HISTORY
The soils observed on site strongly suggest that the area has been influenced by glaciation. Soils
appear to be loess, underlain by glacial till. No bedrock was observed at the depth of the
backhoe pits or hand dug pits.
The subsurface formation in St. Croix County consists of the Prairie Du Chien Group (dolomite
and sandy dolomite). Depth to bedrock ranges from 0 - 15 meters (Brown, B.A. (1988)) This
formation is of Ordovician origin(Paleozoic era 425 mya). Dolomite appears to have been laid
during the early Ordovician period, while the sandstone was laid during the late part of the period
(Paull, R.K. and Paull, R.A. (1977)).
Glaciation of St. Croix County occurred many times during the history of the earth, although the
most recent glaciation, during the Pleistocene epoch(approximately 1 million to 10,000 years
before present), is the most apparent. There were several stages of glacial advance,the most
recent being the Wisconsin stage. This was the result of the advance of the Superior Lobe
(Martin, L. (1965). The Physical Geology of Wisconsin. University of Wisconsin Press,
Madison, Wisconsin).
The glacial till present as parent material in the subsoil of the Christensen site is most likely the
result of deposit from the Superior Lobe material. Loess,present as soil of the Ap, E, and
portions of the Bt horizon, may be
the result of the
influence of the
Eau Galle River or the St
Croix River.
LOCAL HYDROLOGY
As noted on the accompanying topographic maps,regionally,the land surface has a gentle slope
to the west. This slope to the west is presumably the influence of the Eau Galle River, which
lays 0.5 miles west of the western-most boundary of the property and flows in a southerly
direction. The property is approximately 20 feet higher in elevation than the Eau Galle River.
Although the regional flow is westerly,there are considerable topographic changes in the land
surface within the area of the proposed subdivision. These changes have been noted on the
accompanying 2 plot plans. Plot plan 1 shows an overall lay-out of the proposed 5 lot
subdivision. An arbitrary benchmark(BM)has been established on the edge of the blacktop on
110th Avenue. This has been assigned the elevation of 100.0'. As noted,elevations of the
proposed mound sites vary from 100.60' (lot 1)to 110.16' (lot 5).
The topographic maps consulted for this report do not indicate any wetland areas in the vicinity
of the proposed mound SAS's. No naturally occurring areas of standing water were observed in
the area of the proposed mound SAS's. However,the topography does suggest that a water way
exists between lots 1 and 2.
Although no areas of seasonal saturation were observed on the topographic map for this area,the
soil series map did show a wet area and a seasonal creek in the northeast portion of Section 7
(refer to the accompanying photocopy of the soil series map).
SOIL MAPPING OF THE AREA
Direct soil mapping of this area by this soil tester indicates that,taxonomically,this soil is a
Typic Glossaqualf(an aquic alfisol). Aquic alfisols have elluvial and illuvial horizons which are
saturated at some time during the year(as evidenced by the redoximorphic features). Soil series
maps for this area however, characterize this area as Typic Glossoboral£ That is, a cryic alfisol.
Specifically,this is classified as Freeon series soils. Information on the soil series for this area
was provided by the St. Croix County Soil Conservation Service.
As noted in the CST Soil and Site Evaluation, clay loam and silty clay loam was encountered in
all pits in the vicinity of the proposed SAS's. Depth to these layers varied from 11 to 14 inches
in the pits where the layers could be observed. In many pits, standing water prevented the
observation of subsoils.
VARIATIONS IN SOIL CONDITIONS AND SURFACE WATER FLOW
Regional surface water flow(and presumably subsurface flow)is west towards the Eau Galle
River. Topographic changes in the land in the vicinity of the proposed subdivision indicate that
flow can be in all directions from the proposed mound sites. A noticeable water way exists
between lots 1 and 2 as noted on the plot plans for the area.
General surface water flow in the area may be primarily vertical for the first 8 inches as a result
of the relatively permeable upper horizons. Permeability is moderately slow in the subsoil and is
most likely perching above the dense silty clay loam subsoil.
Permeability in the upper horizons may also be the result of extensive cultivation, thus loosening
the soil and increasing its permeability in the upper horizons.
Also present in the Ap horizon, and slightly into the subsoil,were worm channels, suggesting
that the upper horizon was aerated enough to support aerobic organisms. Roots and root
channels were also present in the 0 to 8" range of the soil profile.
Soil colors as noted by this soil tester were 10YR 3/2 from 0-8". This grayish brown color is
darker than the gleyed colors one would associate with a more aquic condition. This suggests
that in the upper soil profile at least,perching conditions do not take place for any considerable
period of time.
No puddled or massive soils were observed in the area of the proposed SAS's to a depth of 8
inches.
Close inspection of the Ap horizon did not indicate the presence of redoximorphic features. This
suggests that although there is not an A+4 situation,there is adequate depth in the A horizon
(approximately 7 inches)to maintain a suitable distance between the bottom of the SAS and the
limiting factor and thus to allow for the placement of a mound SAS.
The gradual appearance of redox features in the soil profile is also significant with respect to the
actual depth of seasonal saturation. Although low chroma and high chroma features were
observed in some areas of the soil immediately below the A horizon,these colors were not
prominent until the Bt horizon,thus suggesting that significant seasonal saturation did not occur
in the A horizon.
In pits where standing water was observed,no water stood within 8 inches of the surface. This is
significant in light of the fact that for 2 days prior to the observation of the pits on lots 3,4, 5
(second visit to the site),there was significant rainfall in St. Croix County. This soil tester
however, does not have information on the exact amount of rainfall during this period.
PROPOSALS
This soil tester feels that mound systems on these sites would adequately provide wastewater
treatment and effluent dispersal as long as the follows design conditions are implemented:
1. The construction of the soil absorption systems must be in the areas designated on the
plot plans.
2. Areas lower in the landscape must not be used for soil absorption systems.
3. The SAS's must be designed very long and narrow with a linear loading rate equal or less
than 4.0 gpd/ft. This may limit the number of bedrooms that a can be placed on the site.
4. At least 2.50 feet of ASTM 33 sand be used under the laterals.
5. Maximum hole spacing in laterals should be 30 inches.
6. Slopes around the mound should be 1:4 rather than the traditional 1:3 to increase the toe
absorption area.
7. The area upslope of the proposed SAS's should be contoured to prevent water from
flowing into the mound areas. In other words,the area around the upslope should be
higher than surrounding areas to encourage water movement away from the proposed
mound.
