Two per- <br />oolation holes were tested and one soil boring taken on each site, <br />Hie percolation holes were dug 6 inches in dlcuneter Md 3 feet in <br />depth. The soil borings were dug 6 inches in diameter to the 4 foot <br />depth and 3 inches in diameter to the 0 foot depth. All holes were dug <br />with bucket type hand augers. <br />Both sites yielded peroolation rates and water tabic depths suf- <br />rioient for standard drainfield systems. The holes on the north site <br />contained better soil at greater depths while the south site had bet­ <br />ter soil in the i4>per layers, <br />A pump and pumping tank will be required on the south site to <br />reach the drainfield area which is at a higher elevation. For the 2 <br />bedroom house to be served 600 sq.ft, of trenches will be needed, <br />which could be two trenches 3 feet wide and 100 fetjt long. If possi­ <br />ble, the trenches should be located more in the area near hole 1 <br />which is more pexneable, and at about a 3-4 fooc ueptn, <br />Ihe south area for the larger house was located in a clearing <br />half way to the lake and contained loamy and sandy loam soils at the <br />upper depths which is very good material for dralnflelds. Because <br />there is no problem in serving this area by gravity from the existing <br />tanks and better soil is at the top, these trenches should be kept <br />about 2 feet deep in thecnatural soil. Although the house la larger, <br />the drainfield will be based on a 5 bedroom house v/hioh would require <br />950 sq, ft. of trench area or about 4 trenches 3 feet wide and 00 feet <br />long. <br />The existing tanks on both hoTues should also be checked for suit­ <br />ability, If any additional information is needed, please contact me. <br />Sincerely, <br />? <br />E <br />? <br />‘.ii <br />P JRCOR, INC. <br />Kark S, Cronberg, f.
