There is an area located immediately <br /> to the East of the present system that originally designated to <br /> be a future site, howeve�•>the City of Oron Znspector determine that depth <br /> water table was at the st�r�ece. <br /> * See the enclosed City of Orono Report for the details . <br /> • Two soil�probes were done on 7/12/07 which indicated the following; <br /> P�-o;�.;�;t ?�10--21 N,:L.;.�:� .::1,_�,i (�;;.l:i� 1 :"; i':: �/1 <br /> Probe # 1A 0-21 inches B1ack Clay Loam 10 YR 2/1 <br /> 21 -37 inches Olive Brown Sand 2 . 5 Y 5/4 <br /> 37-46 inches Gray Clay 2. 5 Y 5/2 <br /> * Mottled soil at 37 inches. <br /> Probe # 2A 0-16 inches Black Clay Loam 10 YR 2/1 <br /> 16- 37 inches Olive Brown Fine Sand 2. 5 Y 5/3 <br /> 37-46 inches Olive Gray Clay 2. 5 Y 4/2 <br /> * Mottled soil at 37 inches. . <br /> I feel that an above ground mound system could be installed in this <br /> area and woul�d be a better site due to that fact that the land slope <br /> is only 3 $ compared to the 10 � that was previuosly tested. The <br /> chances of downslope seepage occur is much smaller wherl the mound <br /> system is placed on the 3$ slope compared to the 10 $. <br /> Therefore I suggest that the City of Orono Inspector �a•some' �`li�� <br /> more borings in this area to actualy establish where the mottled <br /> soil �;:.;�� is located at. <br /> .. .. .. .�,�,� ��,.��.,���� <br /> Rober t A K � ���`-'- ' <br /> . o c h ///�G��ti9� <br /> M.
