MinnesoU. This work was " <br />Mwh 1 1993 Our scope of services you requested consisted of (lerfotming seven (7) sundard <br />penetratiim borings ranging from I2 ’ to 35 ’ below tite ground surface. <br />The subsurface exploration program was performed in general acrordance <br />American Standard for Testing and Maierials (ASTM) procedures, as described in Uie <br />attachment. <br />The test locations were suked aiul selected by you. We have attached a <br />The surface elevations were taken from tlie contour elevations shown on the plan you <br />provided to us. Generally, the surface elevations ranged 956’ to 960 ’. <br />The boring logs suggest a soil profile consists of swamp deposits underlain by sandy lean clay <br />glacial till. <br />Water level measurements were also taken in the open boreholes during and at the completion <br />of the drilling process. As indicated on the attached bonng logs groundwater water was <br />measured to be within 1’ of the surface at the time and location of the borings. <br />If you liave any questions regarding this letter, or if we may be of further assistance, please call <br />me at (612) 659-7405. <br />Very truly yours. <br />Steven J.
