Of ENVIRONMENTAL QUALITY RE: Test Hole and Soil Log Report for Sanitary System W1-2, N=, Lot 182, Section 33, T12N, R3W Seward Meridian Dear Mr. Thomas: We are submitting herewith the test boring results and our comments re- garding soil conditions encountered at the subject site. This investigation was performed in accordance with your request of June 14, 1972, and those procedures outlined in a letter dated September 13, 1971 by Mr. Rolf Strick- land of the Greater Anchorage Area Borough Department of Environmental Quality. A single test hole was put down within the Lot 182 area for the purpose of defining general subsurface soil conditions for the proposed sanitary system. Excavation was accomplished with a tractor -mounted backhoe and the test hole was extended to a total depth of li feet below ground surface. One sample was recovered from the bottom of the test hole and retained for grain size analysis. The sample will be held in storage, up to approximately one month, for possible testing before it is discarded. The final log prepared for the test hole has been included in Drawing A-01. Ground water was not encountered in the test hole. We appreciate being given this opportunity to be of service to you. Should you have any questions with regard to the above, please do not hesitate to contact us. Very truly yours, R & M ENGINEERING & GEOLOGICAL CONSULTANTS V �..�d `I James W.

The maximum daily flow is computed at 75 gallons per capita -day (gcpd). Since "the population of dwellings shall be estimated at two persons per sleeping room," the maximum daily sewage flow for your -bedroom house is 450 gallons per day (gpd). To test the soil absorption capacity as well as the surge capability of your system, 110 percent of the mbximum daily flow or 500 gallons of clear water was added in*50-gallon increments to the seepage pit. The water was obtained from your on-site private well at its maximum sustained rate of about 4 gallons per minute (gpm). The liquid levels were monitored closely to detect any backup in the septic system. Mr. Robert Thomas June 29, 1979 Page -2- The attached Table of Test Data represents the depths of liquid in the septic tank and seepage pit, and the quantities of water added. The septic tank was determined £o be 9.3 feet deep (bottom of tank to ground surface) with an initial depth of 4.1 feet in the tank. The seepage pit was measured to be 9.3 feet deep with an initial depth of 0.5 feet. Ground elevation at the septic tank standpipe is approximately 1.7 feet higherthan at the seepage pit standpipe. The attached Summary of Test Results indicates that the liquid level in the seepage pit at the beginning of testing on Day 2 fell to 0_05 feet below its initial static level on Day 1, during a recovery period of 24 hours. On Day 3, the level had fallen to �•Ofeetbelow its static level on Day 2, during a recovery period of 24 hours. This results in an average rate of fall of 0.02 feet per hour. The level in the seepage pit at its highest level during the test (1.0 feet) was approximately 4.7 feet below the liquid level in the septic tank. Based on two days of testing, a percolation rate for your existing septic system of approximately 500 qpd is indicated. Since an on-site sewage disposal system for a 3 -bedroom dwelling must be capable of disposinq of 450 gallons of sewage per day, your septic system appears to be functioning satis- factorily at this time. Many factors affect the operation of a soil absorption type of sewage disposal system. Soil type, qroundwater depth, aqe and history of maintenance of the system. and types of waste are a few. This test has been performed in an attempt to model actual soil absorption capabilities of your septic system under normal useaqe by considerinq the deqree of saturation of the leach field and surge loads that might be imposed on the system. This test can only evaluate apparent performance at a given point in time, and cannot determine either the condition of the leach field, seepage pit or other components of the septic system, or the depth of the water table. We appreciate the opportunity given to perform this adequacy test. If you have any questions regarding this test, please contact this office.OFAt- ..... \\>t\' .. q Very truly yours, ;�.�P�.••"'•'A CgS`1 ALASKA SOILS INVESTIGATIONS to hen D. Shrader, P.E.
