Certification Number 550 June 16, 1986 Ms. Jean Martineau 589 Bryant Street Maple Plain, MN 55359 RE: Soil Percolation Tests Jab #86-35P at- Lot 3, Block 1 Chippewa Addition City of Orono, Minnesota I was retained by Jean Martineau to conduct percolation tests on this property, in order to provide criteria for the design and installation of an individual sanitary sewage treatment system to handle the sewage flow generated by water -use appliances within a single family dwelling. A total of six (6) soil percoldtion tests were performed on June 10, 1986, at a representative _area on the property. In addition, ten 8 -foot deep soil borings were drilled with a 2" i.d. x 3 1/4" o.d. continuous boring auger to chP:k: for the position of the ground water table and to identify the underlying soil types. Location of tests and borings are shown on the site plan. The percolation tests were performed in accordance with the provisions of W.P.C.-40 "Individual Sewage System Standards." The percolation tests holes were drilled to a conventional depth of between 12 and 25 inches with a 5" 1.d. x 6" .�.d. auger. Two inches of pea gravel were placed in the bottom of each hole to prevent scoring. Water was then added to the test holes and replenished as necessary, maintaining a 12 -inch head of water over the bottom. After a period of saturation, each hole was refilled to a 6 -inch head of water over the bottom, and the percolation tests commenced. Ms. Jean Martineau June 16, 1986 Job #81,-35-P P;-jge 2 RA-commendat ions According to percolation test data and on-site investigation, It is my opinion that a design plan be completed to ensure the proper system for the site. Type of system, location, size, water drainage and diversion are just a few factors for consideration that could greatly affect the proper functioning of a system. Additional information on septic systems can be obtained from the City of Orono staff or the County Agriculture Extension Office. The soil conditions and percolation rates have been established at the test hole locations only. There may be variations in soil stratigraphy between and around borings, and interpolation and extrapolation of the results is not warranted. The boring holes and test holes have been back-filled and Marked with flags. Settling will occur after a period of time; fill should be added again to avoid the holes from becoming a hazard.
