Box 196650 Anchorage, Alaska 99519-6650 RE: Lot 15, Block C, Knik Heights Subdivision Well to Tank Waiver Dear Mr. Roth, There are two septic tanks on this property which fall with in the 100' protective well radius. The first tank is a 1000 gallon tank that was installed in or before 1970. It set approximately 68 feet from the exterior of the well casing. Since this tank was in place in 1970, it is my understanding that a waiver is not required for this tank. The second 500 gallon tank was installed in 1983. This tank sets approximately 72 feet from the well. Though this tank was installed under a Municipal permit, a tank to well waiver is being required in order to bring this system into conformance with the State's mandated requirements. The following covers our evaluation of the criteria for granting a well waiver 1) 2) The well is to reported to be 90' deep and the existing water table (on 4/15/2000) was 43 feet below the ground. The house has been continuously occupied since its construction in 1970. The well water was tested in April and showed no signs of contamination. Coliform was zero, other bacteria was zero, and nitrates were 2.23 which is well below the drinking water standard of 10 mg/ml. The distance from the bottom of the system to the bottom of the water table is estimated at 40 feet. (Point Value = 5.1) Dimond Center Tower, 5th Floor · 800 E. Diraond Blvd., Suite 3-545 · Anchorage, Alaska 99515 (907) 344-1385 ° Fax 344-1383 3) In reviewing well logs for adjacent lots (14 & 16), as well as other lot nearby, the soils range from clays & silts to gravelly silts between the surface and the water table. {Point Value = 5.0) 4) The silty/clay soils which are described in the well logs generally have percolation rates greater than 50 minutes per inch. We expect a majority of the soils between the bottom of the system and the water table to fall with in this range. (Point Value -- 3.0) 5) The water table gradient is from east to west. The water table on the lots to the west is reported to be about the same depth below ground as on the subject lot. We have estimated the gradient at 10%. {Point Value = 6) 6) The horizontal separation between the tank and the well is approximately 72' feet. (Point Value --2.9) The total Point Value that we have calculated is 22.0. This value indicates a very Iow risk of contamination from household sewage. This is supported by the fact that the tank has been in place and in use for over 17 years with out any contamination problems. We recommend approval of the requested waiver. cc: Talley Moon Very truly yours, *-ers ?

Phone z72-8228 Date Engineers Comments: In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with MOA DSD Guidelines & Regulations. The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition, ground water levels that may fluctuate during the year, and the water usage of the family being served by the system. These conditions are outside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. PES can therefore not provide any warranty for future performance nor give any estimate of how long the system will continue to meet the operational requirements of the MOA DSD.

SIGNED Da te EQ-034 (1/74) August 25, 1976 R & M NO. 653125 Mr. Talley Moon Star F~ute A Box 1569 B Anchorage, Alaska 99507 Percolation Test on Existing Disposal System; Lot 15, Block C, Knik Heights subdivision Dear Mr. Moon.' On August 24, 1976, at yourrequest, our office conducted a percolation test on the above described lot. The following table represents the level of the liquid in the tank. The depth of the tank was 8.2 feet below the vent level. The depth of liquid in the tank was initially 3.1 feet above the bottom and 5.1 feet below the top of the stand pipe. The tank had not been pumped prior to the test and was, therefore, assumed to be at the outlet level. For the test, the liquid level was measured from the top of the stand pipe. SU~.~RY OF MEASUREMENTS Level of Liquid Meter Reading Time In Septic Tank In Gallons Remarks 0,,00 5.12' 0:19 5.10' 2...32 5.10' 3..00 5.10' 00.0 (initial) Fill Storage 100.0 Start Test 522.0 422 gal/ 133 min. = 3.17 gpm, End Test 522.0 (final) Check Liquid Level The meter used during the test was a Neptune 5/8" standard water meter which was borrowed from the Anchorage Water Utility. The meter had previously been calibrated and approved for installation by the utility company. Mr. Talley ~!oon August 25, 1976 - Page 2 - Since the house on the lot concerned was occupied, it can be assumed that the leach field in question was at its normal degree of saturation. To further insure normal saturation and to fill any possible storage in the system, 100 gallons of water were added to the tank before beginning the percolation test. If it is assumed that the existing three bedroom residence will house five people, the average daily load on the disposal system can be expected to be 375 gallons per day. The maximum hourly load on the system would be about 0.8 gallons per minute (gpm). Since the existing disposal system accepted 422 gallons in 2.2 hours or 3.2 gpm without a level rise, I would conclude that the leach field is presently performing in a satisfactory manner for a private residence. If you have any questions concerning this test or this letter, please do not hesitate to call. Very truly.yours, R & M CONSULTANTS~ INC. Edward Yarmak, Jr. Junior Engineer EY/sc
