Per our visit to Dear Keith: 4 Lot 10 and Lt 11 the subject properties, 1/18/85 We have reviewed the soils logs, water monitor data, and other data obtained during the course of our work done on the subject lots. In our opinion, the following conditions exist: 1) The ground water was confined to the shallow layers of permeable soils which exist on the lots. The curtain drain has sufficiently blocked the water from entering the s~e layers above Lot 10. Therefore no ground water should be traveling through the shallow permeable laymrs on Lot 11. 2) During soils tests performed on both lots, the silt (ML) layers were dry. This was particulary evident during excavation of the failed system on Lot 11. The water was encountered at 1.5 feet. There was an extremely large amount of water present. Below the permable layers, the ML was relatively dry and no water was present. In our opinion, the shallow layers were the transport medium for the water. Based upon the above system as-builts, and the water monitor information attached, we conclude the following: 1) For all intents and purposes, the system on Lot 10, Block 4, Talus West #2 probably is not able to.pass an adequacy test. However, it is able to meet the needs of the present two occupants who work on the North Slope and are only present two weeks out of the month. Based upon the as-builts and water monitor results near this system, the ground water level is at least 4 feet below the bottom of the system. No signs of effluent exists at the surface. 2) Based 'upon the water monitor results in test holes TH-B1 and TH-B9, the water level is at least 4 feet below the upgraded system on Lot 11 Block 4, Talus West #2. Test hole , TH-Bi, water monitor results should not be taken as an indication of the true ground water level. This test hole is within 7 feet of a failed system of unknown size and type. The water in ~200 ~J¢st 33r,J Au6nu~, Suil~ [~ ,Anckoro% 99503,(907) 561-5040 TH-lB smells septic and is probably the result of drainage from the unknown system. 3) Based upon the as-builts, visual inspections, water monitor results and soils tests on Lot 11, Block 4, Talus West #2, we conclude the ground water level is below the bottom of the existing trench on the lot. The ML layer, actual depth unknown, is at least 18 feet below the ground surface, which is 4 feet below the existing system. This is indicated by the original soils tests done, July 13, 1984 by Kinny Baxter PE which shows ML is not prseent to at least 18 feet. The test holes done May 1, 1984 shows no ML to 15 feet on the lower side of the trench. In conclusion we recommend the following: i) The system on Lot 10, Block 4, Talus West #2, should be allowed to operate until sold or the system fails. Then, an upgrade can be accomplished. In our opinion, the system is operating sufficiently to preclude the necessity of regulated pumping unless the present number of occupants change. 2) The systems on Lot 11, Block 4, Talus West #2 should be approved as-is with both the upgrade and existing system in operation.

MUNICIPALITY OF ANCHORAG~ D~PI'. 'OF HEALTH & ENVIRONMENTAL pROTECTION DEC 6 1984 RECEIVED Dear Keith, I have viewed the properties of Tom Kelly and Mike Driscol, Lots 10,11 Talus West Add No. 2, and obtained water monitor readings for both lots. Enclosed is a record of readings taken periodically since May 1984. Also included is a rough as-built sketch of the curtain drains that were installed on both properties. These are drawn to help in the explanation of the following report. Note the values for the inspection ~zpe located on the north end of the trench on Driscol's lot. The water is at 4ft and then 20ft to the west,~ zn another monitor tube., the water is at 8ft. Since the levels differ by 4ft in less than a 20 f~t~ ld~s~ance there may be indication of an impermeable layer of soil. It appears that ground water is moving through the 2ft layer of organic material along the impermeable layer of soil. As this water encounters a void such as a sewer system, monitor tube, etc. it fills the void to the static water level. Hence the erroneous data. Mr. Kelly's upgraded pystem appears to be operating very well. Water monitors show the water level to be at a depth of 8ft or 6ft below the bottom of the trench. This exceeds the 4ft requirement of the DHEP. The inspection pipe.located at the end of the old system is dry all the way to the bottom, indicating that the new system has not exceeded the design capacity. Acreage Systems, Inc. installed both of the curtain drains and the septic system upgrade. While installing the Driscol curtain drain some interesting conditions were encountered. The reason for altering the route of the drain was to avoid some seepage of septic system effluent. This was found at a point where the turn was to begin on the originally proposed design. The route was modified so that the turn was moved to a point 20ft further where dry ground was located. After the turn was negotiated and the excavation carried another 30-40ft, some buried brush was found to a depth of about 8ft. From 8ft to 16ft hard clay was 1200 ~Bsl 33,d encountered. This situation lasted for about 90 lineal feet. The brush filled area contained a lot of water but no septic tank effluent. To confirm the condition of the Driscol septic system, additional holes will have to be drilled. If this is done in the winter the influence of the suspected groundwater flow mentioned earlier may be confirmed or denied. If the water problem is caused by a shallow water movement then the use of monitor tubes will be useless. Should you have any questions concerning this matter please do not hesitate to contact me.
