Mr. Chuck Van Eeckhout <br />May 12. 1977 <br />Page two <br />that the level of the ground water table at the time of the testing was below <br />a depth of 8 feet from the ground surface at the boring location, or below an <br />elevation of 83.9 feet. <br />Fluctuations in the water level may occur over a wide range, depending upon <br />the amount of precipitation, evaporation, and surface runoff, which will vary with <br />the seasonal changes. <br />Based on the test results, installation of individual soil absorption disposal <br />systems should be acceptable for recommended design rate of 60 minutes per inch, <br />requiring a minimum of 330 square feet of absorption area per bedroom. The observed <br />water table in the area is at a depth greater than 6.5 feet below the existing ground <br />surface, making an absorption system acceptable according to State Code Regulation. <br />The provisions of the "Ordinance and Code Regulating Individual Sewage Disposal Systems" <br />(1971)» as recommended by the Minnesota Department of Health, as well as any local <br />ordinances and codes, should be followed in the design and installation of the disposal <br />system. <br />If there are any questions with regard to this report, please do not hesitate <br />to contact us. <br />Very truly yours, <br />SOIL TESTING SERVICES OF MINNESOTA, INC. <br />James H.
