INTRODUCTION
This report represents the preliminary results of an investigation of the
subsurface soil conditions on lots 1 and 2 of the proposed Eklutna Lake Acres
Subdivision located in the S 1/2 of the NE 1/4 of the SE 1/4 of the SE 1/4 of
Section 1, T15N, PIE, Seward Meridian, Alaska.
The purpose of the investigation was to determine the potential for wastewmter
disposal on the two lots.
Authorization for the investigation was recieved on May 25, 1985 from Dorothy
M. and Theresa Marie Hendrick the land owners, through Larry Maulden an agent
of the Jack White Company.
FIELD WORK DESCRIPTION
~estholes 1 and 2 were drilled on Ma'y'27, 1985 using a Nodwell mounted
B-61 drill owned and operated by Denalt Drilling, Inc. of Anchorage, Alaska.
The driller was Dave Bruke and was assisted by Brian Rose. Derek Howard of
Alaska Land Development Services, Inc. was present to log the testholes and
take material samples.
The drill was an 8" continuous flight, hollow stem auger. Split spoon
penetrations were also recorded at various levels in the two testholes. The
results of the penetration tests are beyond the scope of this report.
ANALYSIS
The soil samples taken from the two testholes were brought to the office
of Alaska Land Development Services, Inc. The samples were divided into 7
groups by visual analysis. A representive sample was taken from four of the
seven groups and a sieve analysis was then performed on the sample. The.
result from the sieve analysis was then used to classify the soils using the
Unified Soils Classification System. Test results are presented in the
Appendix.
CONCLUSION
The site appears suitable for wastewater disposal. The soils encountered
on the site are of the granular type with no evident ground water. A more
thorough investigation will be required at the time a specific septic site is
