One was completed on 10-15-97 <br />finding redo features at 28" & the 2nd one by Maple ridge Sewer Service by Maple <br />Ridge Sewer Service finding redo features at 32". <br />Soil probing was completed at the downslope toe of the mound finding the sand to be <br />brown in color with no sign of hydraulic overloading and dry (gray soil would indicate <br />saturated soil). A soil probe into the rock bed found no sign of hydraulic overloading <br />or plugging. Soil boring #1 completed through the mound found 14" of sand below <br />the rock bed leaving a 4211(3.51) separation. <br />This system meets the required 3' separation from the bottom of the rock bed & <br />redox features and is classified as in compliance with Minnesota Chapter 7080 rules. <br />The tanks were pumped by Kothrade Sewer, Water & Excavating, Inc. & were found <br />to be compliant. <br />
