<br /> On May 11 and 13, 1983� we put down three hand auger borings aecretary/treasurer
<br /> and ran six percolation tests for a propused sewage treatment MOMEOFFICE:
<br /> system. Two borings and four tests were made in the primary ST. PAUL, MN -
<br /> treatment area, and one boring and two percolation tests -
<br /> were made in the alternate (future) location. All the boring OFFICESIN:
<br /> and test locations are shown on the attached sketch. MANKATO, nnn;
<br /> FiOCHESTER, MN
<br /> SOIL CONDITIONS
<br /> �� The attached copies of the field boring logs show th: t the
<br /> � soil profile is fairly similar throughout. About '-;' of dark
<br /> � brown topsoil overlies sandy clay (CL), which classifies as
<br /> � a clay loam according to the USDA Soil Textural Classification
<br /> �t. System. The clayey soil changes in color from a fairly uni`orm
<br /> �,� brown to a brown mottled as depth increases. The mottled brown
<br /> �,� is not the typical multi-colored, mottled soil , which indicates
<br /> ,� a fluct�ating ground water table,
<br /> �� GROUND WATER
<br /> �1
<br /> , � No wnter was noted in the borings at completian, although the
<br /> soil was nearly saturated, which is typical of late sprinq
<br /> cond:tions. Later, water was noted at depths of about 5' in borings
<br /> 1 and 2. This may have been due to the heavy rains the pre-
<br /> vious day and eveniny; or, it rnay be due to the temporary
<br /> spring conditions.
