Sincereiy, Ji~62/ej/E2 April 17, 1981 W.O. #A19708 Second and Fourth Anchorage Limited Partnership 4611 Business Park Blvd. Anchorage, Alaska 99503 Attention: Mr. Les Pace Re: Subsurface Investigation for Suitabilityof On-Site Sewage Disposal, Lot 4, Block 1; Lot 2, Block 2; Lot 3, Block 2; Lot 8, Block 2; Lot 9, Block 2; Lot 10, Block 2; Lot 17, Block 2;~..Lot 19, Block 2; Lot 26, Block 2; Lot 3, Block 4; Lot 4, Bloc~4; Lot 6, Block 4; Lot 12, Block 4; Lot 13, Block 4; Lot 14, Block 4, Greenbrook Subdivision Dear Mr. Pace: During March and April of 1981,. we drilled a 15 foot boring on each of the above lots and placed a perforated, 3/4 inch PVC pipe in each hole rio that the water table could be monitored over a period of time and a percolation test run in the hole. The holes were drilled using a Nodwell mounted, Mobile BS0 drill rig owned and operated by Denali Drilling, Inc. The drilling was supervised and the test holes logged by Mr. Ted Krupka, senior technician, and Mr. O.M. ~atch, geologist with Alaska. Testlab. After the holes were drilled, our technician ~eturned on several occasions and checked the water level in each of the test holes. After a period of time the holes~were~~'~>left to stand overnight, saturated again and a perco/~t~on'"'t~'~t run. The percolation test was run by monitoring the drop in the water table elevation at 10 minute intervals for a minimum of one hour. The percolation rate listed in this report was computed using the slowest 20 minutes 'of that percolation test. Included with this report is a test hole location sketch for each lot and a log of the boring placed on each lot. The results of this exploration are described as follows: Lot 4, Block 1 The water table elevation measured in the test hole at this site remained fairly constant at about 12 feet. The percolation rate measured on April 15 was 6.0 minutes/inch. Because of the need to keep the system shallow and ~he high silt content, we recommend a more conservative design percolation rate of 10.0 minutes/inch. Second and Fourth Anchorage Limited Partnership .April 17, 1981 Page Three rate was 5.2 minutes/inch, however, we recommend a design rate of 10.0 minutes/inch. Since the seasonal water level is quite high, we recommend a mounded disposal system so sufficient separation is achieved. Lot 10, Block 2 The test hole was located in the southwest corner of the lot, and we recommend that the sewage disposal system be placed in this area. The water level is quite near the surface towards the front of the lot. The water level while drilling on April 8 was 9.0 feet, then was found at about 12 feet over the next few days. On April 14, the percolation rate was measured at 2.5 minutes/inch. We recommend that a more conservative rate. of 10.0 minutes/inch be used, due to'~the silty nature of the upper soils. The system should be placed as ~igh as possible, in the upper 8 to 10 feet, to avoid conflicts with the seasonal high water, mounding may be necessary for insulation. Lot 17, Block 2 No ground water was encountered while drilling on this lot on April 8, or when checked again April 9 and April 16. The measured percolation rate was 5.4 minutes/inch, however, we recommend a more conservative design rate of 10.0 minutes/inch because of the siltier nature of the soils. Lot 19, Block 2 No water table was observed in the 16 foot test hole while drilling on April 8, or on April 9. The percolation rate was measured at 8.9 minutes/inch, however, we recommend a more conservative design rate of 10.0 minutes/inch because of the silty nature of the soils. The system should be placed as high as possible, as high seasonal water levels were found.in the immediate area. Lot 26, Block 2 ~he test hole was drilled near the center of the lot April 8, and no water was observed. The test hole was also found dry April 9.. The measured percolation rate was 6.2 minutes/inch. Lot 3, Block 4 No water was observed in the test hole at this site while drilling on April 8, bu~ was at 12.5 feet the following day. The measured percolation rate was 14.6 minutes/inch. The disposal system should be kept as high as possible to avoid conflicts with the ,A I I , .,',,I?,,~,K,.\ II%IIAH Second and Fourth Anchorage Limited Partnership April 17, 1981 Page Five checked April '9. The measured percolation rate was 4.0 minutes/inch. We recommend a more conservative rate of 10.0 minutes/inch be used, since the upper soil is silt.
