<br /> On July 17-18, l�til six percolation holes were tested and three
<br /> ` soil borings taken on the above lot. The holes �rere tested ir� an area
<br /> below th� proposed hoase ar.d at lea�t 7� �eet up i'roM the me.rsh. The
<br /> holes were c?:z� 3�Yeet ueep at �he upper level and 2.5 foet deep at
<br /> the lower le�ei. to te::t i'or a shallow trench system, sinr,e bette^
<br /> soils existed near the top and Q high water table er.ists near tha
<br /> ; marsh. The percolatior� 'r.oles were dug 6 inch�;s in dia,:,eter to the ' � �
<br /> fall depth whi1Q the �oil borin�s were dug h inches in ;�ie^�eter to
<br /> the 4 foot deFth and 3 inches in diameter to the ramaining depth.
<br /> All holes were du� with bucket ty-ve hand augers.
<br /> A 9erS suitable sa.�dy loar. material has been rra�hod dok*n the
<br /> slope and deposited in the drainfield aree� over the black loa,;, and
<br /> underlyin� clay loa_ms, lnis up~�er m�terial should be utilized so the �
