__ . - - _.._.. ,. . ._._. _._.. <br /> 1 <br /> 1 rypically very lo�liDed aad highly dependant upon seasonal flucd�ations in rainfall. W:uer from <br /> the inurflow zon� on tl�e site was not observed to be outwaterin� in any surfxce sxpages or <br /> �� springs at t6e time of our field work. <br /> 1 5.2.2 Shsllow �nd Wa�r <br /> 1 Ground water was encountered at reladvely shallow depths in EP-3, EP-10, EP-12 and. EP-16. <br /> The ground water observed in EP-3 aad EP-16 was noted at depths of about 9 to 14 fat below dx <br /> � gronnd surface. As shown on the logs, both of these exploradon pits were uiminated in the <br /> Vashoa advance outwash. However, in EP-10, the base+ of the Vashon outwash unit was <br /> penenated where it was u�erlain by pre-Vashon undit�etentiated silt. Cround water in uP-10 was <br /> � perched on the silt, and a sunilar relarionstrip may ezist at EP3 aai EP-16. Minor ground water <br /> seepage was e�ounured in the Vashon lodgement till at a depth of about 5 feet in EP-12. This <br /> is interpreted to represent a very Iacaliud waur lxaring interval in a zone of reladvely higtKr <br /> � permeabiliry. <br /> 5.2.3 ReYionst O�twash A �a�ifer <br /> IRegional ground water studies hy Newcomb (1952) indicate d�at a regional outwash aquifer <br /> � discharges in rn�mer�s seeps and springs along the upland plauau overlooldng Possession Sound. <br /> This interprnation is consistent with the seepage noted emanadng from outwash sediments along <br /> Narbeck Creek. The depth to the regional ground water system is infernd to be 50 to 100 fat <br /> � below the upland plateau. <br /> � <br /> ' <br /> I <br /> J <br /> I <br /> I <br /> 1 <br /> i <br /> 6 <br /> ' <br />
