Mr. Dan Alex
Field Testing for Suitability for On-Site Wastewater
Disposal, Lots 135A and 135B, Birchwood Postal Tract
As authorized by Mr. Les Brattain of Tryck, Nyman and Hayes
Engineers, a test boring and percolation test has been completed
on each of the subject lots. The exploration was conducted using
a truck mounted Mobile Drill B50 rig equipped with a solid flight
auger. The rig is owned and operated by Denali Drilling, Inc.
The bonings were logged by Mr. T.K. Krupka, Alaska Testlab tech-
nician. The percolation tests were performed by Mr. O.M. Hatch,
geologist with Alaska Testlab. The approximate boring locations
are shown on figure A. These were located in the field by Tryck,
Nyman and Hayes personnel.
Tables A and B are the logs of the b~rings, showing the visual
soil classifications. Upon completion of the boring, a perforated
PVC pipe was inserted in the hole and it was filled with water°
The following day, the hole was refilled with water and the
percolation test run. For the percolation 'test the depth to
water was measured every 10 minutes over a one hour period, with
the following results:
