A mound type system will need to be installed to replace the esisting system because of the high seasonal water table. �dditional borings will be completed after the frost is out. This report was written on 1�Iarch 14, 1999. GENERAL The contents of this report are to be applied to the listed property only and are cop_v righted. Reprints are available from DH Excavating. The soil conditions have been established at the test hole locations only. There mav be variarions in soil strati�aphy between and around the borings, therefore the extrapolarion and interpolation of the results are not warranted. If you should have any questions or need further information, you may contact the staff at the Steve Weckman at the Citv of Orono, or DH Excavating at your convenience. 'Sincerely W ca rrig Log of Soil Borings taken on vlarch 5, 1999 to evaluate the soils located on the Thompson property on Old Crystal Bay Road, designated Lot 2, to determine the depth to the seasonally high water table. Because of the high seasonally water table the esisting system is failing and will require a replacement mound type system. All borina measurements are in inches unless otherwise noted. The soils are located on the cro��n and shoulder slope of a knoll. The parent material is glacial till with loamy colluvium in the Hamel soils. The soils are typed as being Hamel Loam and Lester Clav Loam bv the USDA soils survey. The primary site is in Hamel soils wzth some runoff covering the site. There �vas no bedrock or water present in the borings.
