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 Ronald L. Griffith P.E. Alaska Civil Engineer CE #6049 Alaska Land Development Services, Inc.
