<br />SP86-009 <br />Printing Enterprises, Inc. <br /> <br />- 4 - <br /> <br />March 24, 1986 <br /> <br />6.5 feet) fill and organic materials were encountered in borings <br />taken in the south and eastern portions of the building area. <br /> <br />Penetration resistances within the fill ranged from 4 to 12 blows <br />per foot (BPF). Penetration resistances within the glacial out- <br />wash and till ranged from 2 to 23 BPF, indicating the sands to be <br />in a loose to medium dense condition and the cohesive soils to be <br />soft to very stiff in consistency. <br /> <br />Power auger borings B-15 and B-16 encountered 1/2 <br />topsoil (clayey sand and silty sand) overlying <br />(clayey sand) to the termination depths of 15 feet. <br /> <br />to 2 feet of <br />glacial till <br /> <br />B.3. Ground Water Condi tions: Water was encountered in bore <br />holes ST-9 and ST-11 at the 6-1/2 and 7 foot depths, 4 and 8 <br />hours, respectively, after wi thdrawal of the augers. Ground <br />water was not observed in the remaining borings. However, wet <br />and waterbearing soils were observed in each bore hole. It must <br />be noted that the period of water level observation was relati- <br />vely short. Because of the low permeability of the soils encoun- <br />tered, a period of several days may be necessary for water in the <br />bore holes to stabilize at the static ground water level. In <br />addition, seasonal and annual fluctuations in ground water levels <br />should be expected. Based upon water level observations and soil <br />moisture contents observed during drilling, it appears that the <br />current ground water level is at approximately elevation 89 on <br />our assumed datum. <br /> <br />C.
