ADDITIONAL SITE EVALUATION INFORMATION <br /> ON THE PAUL PHILLIPS PROPERTY <br /> ORONO, MINNESOTA <br /> 6-14-85 <br /> 0) On May 23-25, 1985 additional septic testing was done on the the existing <br /> house for an alternate drainfield site. This site was to the south of the <br /> house and yielded an average percolation rate of 34.0 minutes per inch. How- <br /> ever, because of the high water table, a shallow trench system with an inter- <br /> ceptor draintile ' <br /> nother alternate site was tested on Lot 1 to the north of the previous- <br /> ly tested sites and yielded results similar to the prior results. Percolation <br /> holes 7 & 8 were tested here and had an average percolation rate of 24.6 min- <br /> utes per inch but a high seasonal water table which would require the use of <br /> a mound system. Care must also be taken to prevent runoff water from the road- <br /> way ditch from entering the drainfield area. <br /> If there are any other questions, lease <br /> Sincerely, <br /> PERCOR, INC.. <br /> Mark S.
