IVovember 7�1 1992 4 9?3-1175 thr weathered HU waa a dense, nonweathered till that eztended to the maximum depth of exca�ation. Compact to denee fnterbeds of glacial outrvash eand and gravel were encountered in eight of the test pits and ranged in thiekness from 1 foot to 2.3 feet. A {aose layer oE 811 leae than two Eeet in thicknese was encountered in test pib TP-2 and 1'F-S just below the topaoil and in test pit TP-15 at the ground aurface. Ceneral!y thr, aoil untb encountered in our teat pib consisted of the following: Ejj,j, The fill conaiated of looae, moderate brown to dark yellowish brown, eilt with aome fine to medium eand and little gravel. TOpSOIL The topsoil consisted of looae, dusky yeUowuh brown, ailt ; with aome fine to medtum sand, trace gravel, and abundant smaU roob. � WEATHERED TILL The weathered till coneisted of loose to compact, moderate I brown,fine to medium sand wtth aome ailt, Uttle to some gravel,and trace cobblea. lC�i '�Sjj The outwaeh con�i�ted of compad to dense, olive brown to light brown,eand and gravel, with little cobblee and trace silt. � �,], The till conaisted of den�e to very denae, light oGve gray, fine � to med:um sand with aome gravel, llttle atlt, and trace cobbles. i SurE�ce W�ter and Groundwater The aite wes predom(nately dry at the time of our investigaHon with the exception of three ' areaa of aurface water as shown on Figure 2. The aurface water in the northeast comer of the afte and the areaa ivithin the awale appear to be ponded behind soil mounded across naturel drainage paths as a result of previous clearing operoNona. Surface water waa al�o impounded within the emall depreasion located in the central pnrtion of the site. At the time of our fteld lnvestigatio� on November 10, and 11,1992, gtoundwater aeepage waa encountered in teat pib TP-9 and TP-10 at depths ranging from 2 feet to 4.6 feet. The groundwater aeepage was minor at a depth of 2 feet in teat p3t TP-9. Seepage in teat pit TP-10 waa aignificant with minor aeepage occurring at 4.6 feet and moderately heavy flow occurring at 6 feet to 9.2 feet. The groundwater enmuntered tn test pits TP-9 and TP-10 wa� confined within the • i�terbedded autwaah eand and gravel. Although groundwater waa encountered only in the northeast portion of the aite, it is possible, due to the existing soil sequence, for confined groundwater to be present at ather Iocallons. • i i � . � � polderAssoclates
