INTRODUCTION On February 11, 2010 Mark Iverson, Professional Soil Scientist #197 and Certified Soil Tester #46672, completed an interpretive onsite soils evaluation. An interpretive evaluation is required because the site does not meet the requirements to install a new private on-site waste treatment system (POWTS) through completion of a conventional onsite soils evaluation (<A+4 inches of acceptable soil must be present). The onsite evaluation was completed through the observation of the soil profiles at five test pit locations. This report has been prepared to present the results of an interpretive onsite soils evaluation. The evaluation was completed at the request of the client, Scott Peavey. The property is located at the SE corner of the intersection of Hwy. N and 250th Street in the Township of Eau Galle, St. Croix County, Wisconsin. II. PROJECT INFORMATION The following is site-specific background information: Property Owner: Scott Peavey 299 250th Street Woodville, WI 54028 Site Location: NW 1/4 of the SW '/4, Sec. 14, Town 28N, Range 16W Parcel ID # 008-1041-50-050 Town of Eau Galle St. Croix County Historic Land Use: Agricultural crop production Current Land Use: Agricultural crop production - Corn Vegetation: The vegetation within the tested area consists of field corn. The field was covered with 12 to 18 inches of snow. Due to the snow a survey for hydric vegetation could not be completed. Weather Conditions: The temperature was in the mid 20's and the sky was clear. The soil evaluation was completed between 11:00 & 1:30. III. METHOD This interpretive evaluation and report was completed following the guidelines set forth in Comm 85.60(2) of the Wisconsin Administrative Code and in the summary provided by Leroy Jansky titled, "Preparing the Interpretive Determination Report" (March 13, 2002). 1 IV. DISCUSSION OF RESULTS i i A. Local Hydrology 1. Surface Water Drainage Patterns - Minimal surface water drainage is received over the tested area. The proposed system contour (100') is located at the shoulder of the slope. The summit of the slope is 60 feet or less from the 100' foot contour. The slope within the proposed system area is approximately 5 to 6%. 2. Subsurface Water Drainage - The silt loam texture and lack of compaction within the surface horizon of the field offers good infiltration and lateral movement of precipitation received on site. Weak to moderate compaction (platy structure) was observed in the second horizon of all borings. The platy structure limits the infiltration of surface water within the profile. During and immediately following frozen conditions and following heavy precipitation events, runoff will be much greater. 3. Artificial Drainage Devices - No artificial drainage devices were observed during the completion of the evaluation. 4. Contributing Drainage Area - The proposed system area is located on the shoulder of the hill slope profile. The summit of the profile is located approximately 20 to 60 feet south of the proposed installation contour. There is contributing drainage area up slope of the tested area. A surface water diversion ditch will need to be constructed around the proposed system or the summit of the slope will need to be modified to encourage drainage to the south to limit the effects of potential surface water received from upslope. 5. Soil Saturation - Saturated soil was not observed in any of the test pits completed on site. 6. Surface Water Elevations - Surface water within the immediate vicinity of the site, if present, has been identified on Figure 1. B. Geomorphology 1. Parent Material - The parent material is loess over glacial outwash/till. 2. Landform Type - Ground moraines. C. Soil Disturbance and Hydraulic Modifications The proposed system location is in an existing corn field. No hydraulic modifications, such as drain tile or ditches, were observed at the time of the assessment. No additional surface water is received from impervious surfaces. 2 D. Landscape Position and Local Topography The regional topography is shown on figure 1. The ground surface elevation is approximately 1160 feet mean sea level (msl). The topography within the proposed system area is shown on the site map included in Appendix A. The proposed system elevation is 100.00 feet (site specific elevation). The shape of the slope within the proposed system area is linear (perpendicular to the contour) and linear (parallel to the contour).

Wetland Inventory Map The Wisconsin Department of Natural Resources surface water viewer was reviewed to identify wetlands mapped on the property. The wetland inventory map is included as figure 3. Wetlands are mapped on the south side of the property however none were identified near the test location. 4 FIGURE 3 - WETLAND INVENTROY MAP IV G. Field Observations The soil present within the proposed system area is similar to the description of the mapped soil unit Vlasaty, identified on the Natural Resources Conservation Service Web Soil Survey. The A horizon extends 7 to 8 inches below surface within the proposed system area (Borings 1, 2, and 3). Moderate granular structure is dominant in the surface horizon. Weak, fine to medium platy structure is present in the second horizon directly below the plow zone for one to three inches. Moderate blocky structure extends from the third horizon to the weak, coarse, blocky to massive clay loam, which is encountered at the base of the test pit within the system area. The soil profile descriptions were complete 24 to 30 inches below surface. Moderate compaction (platy structure) was seen in the second horizon of all test pits. The platy structure is common in many of the glacial soils in this region due to seasonal tillage. Moderate granular structure in the A horizon (0 to 6-8 inches) will provide for good infiltration and lateral movement of the effluent. The soil on site does not meet the hydric soil criteria. The lack of hydric soils indicates that the soil is likely not saturated for greater than 5% of the growing season (approximately 7 consecutive days). A dominance of hydrophytic vegetation was not observed within the proposed system area. The lack of these features does not preclude the possibility that the soil is saturated for a prolonged period of time prior to or on occasion during the growing season. 5 Due to the sunny conditions combined with the snow cover, soil samples were collected from B-3 in the field and taken inside to confirm the soil morphology and color. The indoor comparison was the same as the conditions logged in the field. H. Comparative Analysis Three soil borings (B-1, B-2, and B-3) were completed within the proposed system area. Two additional borings were completed, one upslope (B-5) and one down slope (B-4) of the proposed system area. The texture, structure, and depth to redox features of borings 4 and 5 were relatively similar to that of the tested area. The down slope boring B-4 had moderate platy structure in the second horizon versus weak. This indicates that soil was likely more moist during spring tillage and more subject to compaction. The soil color also varied in the second horizon of boring #4. The hue of the redox features was a more red color 5YR vs. 7.5YR. This likely indicates that this area is more subject regular soil saturation and subsequent drying. This causes more oxidized iron accumulation in this zone. Redox features were observed directly beneath the plow zone in all borings accept B-2. The redox feature in Boring #2 were not present until the third horizon. Boring #2 was completed on the backslope of the hill profile. This allowed for better surface water drainage in this profile position. The bed of the system is proposed to be installed on the shoulder of the slope. Therefore the majority of the system will be constructed on the backslope and will take advantage of the better soil conditions observed at this profile position. I. Government Reports and Comments No other government reports have been observed for this property. V. Conclusions and Recommendations Seasonal saturation appears to be limited to greater than 7 inches below surface within the proposed system area the majority of the time. The lack of soil dominated by low chroma colors within the proposed system area indicates that the redoximorphic features observed are not due to a high water table or perching conditions. The cause of the redox features observed in the test pits is most likely attributed to short-term seasonal saturation due to slow permeability of the dense glacial subsoils. Reorientation of the platy structure observed by chisel plowing after placing 3 to 4 inches of ASTM-33 sand on the system area will aid the dispersion of effluent through the subsoil. The site is suitable for installation of a POWTS (mound system) for the following reasons: 6 I.) Redoximorphic features were not observed in the upper 7 inches of soil within the proposed system area. 2.) Neither hydric soils nor a dominance of hydrophytic vegetation are present within the proposed system area. 3.) Topographic features that cause slow infiltration near the top of the slope can be modified so that surface water flow is directed away from the proposed system area. 4.) The slope at the proposed system location is 5 to 6%. The slope is uniform with no dips or valleys at the proposed system location. 5.) The lack of soil dominated by low chroma colors indicates that the redoximorphic features observed at depth are due to temporary seasonal saturation and not from a permanently high water table or perching condition. The following recommendations should be considered during installation of the proposed system: 1. The system should be installed on the 100.0' contour to stay within the tested area. 2. The system should constructed closer to B-3 to allow room for surface water drainage around the east side of the system. 3. Sand fill shall consist of 2.5' of material meeting ASTM C-33 specifications. 4. To break up the platy structure tillage must be completed with a chisel plow to a minimum depth of 12 inches below native ground surface. This must be completed during dry conditions after placing 3 to 4 inches ASTM C-33 soil over the infiltration surface. 5. The basal loading rate shall not exceed 0.2 GPD/12. 6. The system shall be designed to have a linear loading rate of 4.5 GPD/ft or less. 7. The system will follow the contour (100.0') and be nearly linear. 8. The area upslope of the mound must be altered to encourage surface water received on the summit of the slope to be dispersed via surface water flow rather than infiltration. The final approval of this site must be made by the Wisconsin Department of Commerce and the St. Croix County Zoning Department.
