VanEeckhout Building Corporation <br />Attention: Mr. Chuck VanEeckhout - 3 - August 27, 19S] <br />Percolation test results are, in general, consistent with the texture of the <br />s it materials in which the percolation tests were performed. <br />The City of Orono requires at least three (3.0) feet elevation difference <br />between the bottom of standard soil ab;:urption trenches and the water table <br />or indicators of periodic saturation, such as soil mottling. The City of <br />Orono also stipulates that soils acceptable for standard soil absorption <br />systems should have a percolation rate faster than 60 minu::es per inch. Test <br />results indicate that tested soils at the proposed lots do ncttreet both of <br />these requirements. Therefore, the soils are unsuitable for standard soil <br />absorption systems. However, the soil tests show that six of the seven lots <br />are acceptable for standard mound s-stems. <br />Siting criteria for mound systems include the following requirements: <br />Slope (%) Percolation Kate (min/in) <br />0-3 60-120 <br />3-6 30-60 <br />6-12 5-30 (approval contingent on inspection <br />by Inspector) <br />Percolation test results indicate that most of the proposed lots meet the <br />above criteria. The lest with the " W' testholes will require an engineered, <br />mound design to overcome moo:; limitations. <br />After proposed house locations are decided, indi...idual mound designs show' <br />be made. If proposed house locations cover sol. test areas, additional <br />percolation testing may be required. <br />The sole purpose of soils data contained herein is evaluation of soil suit- <br />ability for on -site absorption of septic tank effluent at the test site. <br />Although soil texture and horizonation information and ground water elevation <br />data may be helpful for the setting of basement elevations at tais site, we <br />cannot warrant any such interpretations or use of this data for other purposes. <br />Tf you have any questions about inforniation contained in this report, please <br />eel free to contact n . <br />�-rice teIY, <br />P',W:SON ANDERSON ASSOCIATES, INC. <br />t.ary J.
