Job No: 9C849 Re: Soil Percolation Test - Block 1, Lot 1 of Chippewa Second Addition, Orono, Minnesota. Dear Sir: We were retained by you to perform soil percolation tests at the above property (see Drawing No. 1 attached). The tests were performed on October 15, 1976. The procedure was in accordance with the methods designated by the Minnesota Department of Health, 1971, and somehwat modified our engineering judgement. The attached log sheet indicates the observed percolation rates at each of the test holes (P-1 through P-6). The observed percolation rates at each of the test holes was within the maximum allowable rate of 60 minutes per inch, as recom- mended by the Minnesota Department of Health. Based on these observations, the in- stallation of an individual soil absorption system will be acceptable in the area tested. In addition to the above percolation test holes, one test boring B-1 was drilled to a depth of 10 feet below the existing ground surface to determine if the water table is less than that depth. According to the readings listed below, it Is our opinion that the level of the long term ground water table was located at a depth greater than 10 feet below the existing ground surface at the time of testing. wiltloo C.

Based on the test results, installation of an individual soil absorption disposal system should be acceptable for a recommended design rate of 30 minutes per inch. The observed water table in the area is at a depth greater than 6 1/2 feet below the existing ground surface, making an absorption system accep- table according to State Code regulations. The provisions of the "Ordinance and Code Regulating Individual Sewage Disposal Systems" (1971), as recommended by the Minnesota Department of Health, as well as any local ordinances and code::, should be followed in the design and installation of the disposal system.
