Engineer's Comments: This investigation was completed in compliance with' ADEC and MOA regulations. The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface,changes inland use, local soil characteristics, groundwater levels that may fluctuate during the year and the water usage of the family being served by the system. The operational life of all well and septic systems are subject to these various and dynamic characteristics and are outside the control of the evaluator of the well and septic system. Therefore, ArcTerra can not give any estimate of how long a system will function satisfactory for current or future occupants or can ArcTerra guarantee that no unseen \ encroachments,deficiencies or discrepancies exist.

Based on those inspections it appears that the system is working properly. However, due to the steep topography above the system, there may be some seasonal mn off during breakup events which may be intercepted by the system. It is suggested tbat the system performance be monitored during spring breakup in 1994 to determine if any corrective measures such as construction of water bars may be required. Also attached is a letter from Flattop Technical Services which more fully describes the system performance. Based on DHHS inspection of the system the attached Health Authority Approval is issued unconditionally. TECHNICAL CIYIL & ENVIRONMENTAL ENGINEERING * ENERGY CONSERVATION & ANALYSIS TItEODORE F. MOORE, ILl';. June 28, 1993 14530 ECltO ST. PH: (907) 345-1355 ANCHORAGE, ALASKA 99516 John Smith M.O.A. DHHS P.O. Box 19-6650 Anchorage, AK 99519 Dem' Mr. Smith: 0 / '~ J o (r~ ~-g - 3 ~' Enclosed m'e copies of om' adequacy test data sheets for the on-site water supply m~d wastewater disposal systems serving the Bash residence on Tract 1 of Rabbit Creek S/D #2, located at 7035 Our Own Lane. You may recall our phone conversation on May 14, during which I described the quite different perfo~xnances we had observed during our adequacy tests in April and May of this yem'. At the time you indicated that DHHS probably would be willing to issue a HAA certificate, based on the latter adequacy test demonstrating that the em'lier poor performance was a temporary effect of breakup conditions. The following is a description of our test procedta'e and findings. According to the as-built inspection report on file at yom' office, the wastewater disposal system was installed in August of 1981 and consists of a 1250 gallon septic tank followed by two pm'allel soil absorption U'enches. The house and septic system m'e located on a gently sloping bench midway up a steep hillside above Rabbit Creek. As constructed, the upper u'ench is 62 feet long with 3.5 feet of sewer gravel and must be surcharged in order for effluent to flow over into the lower 29 foot long trench with 6 feet of sewer gravel. It appem's that the standpipes in each of the trench segments peneu'ate little, if any, below the level of the horizontal clisu~ibution pipes. Our lb'st adequacy test was conducted on April 6, during the midst of an early breakup at a time when the snow was rapidly melting on this south facing lot. At the stm't of our test the fluid level in the standpipe for the lower trench was 17 inches below ground level, and in the standpipe for the upper trench was 39 inches below ground level. The fluid levels in the septic tank appem'ed to be normal. The addition of 113 gallons of water to the system caused the fluid level in the lower standpipe to rise 8 inches, in the upper trench standpipe to rise 7 inches, and in the septic tank to rise 4 inches. Over the next 2 hours all fluid levels receded only approximately 1/2 inch. Based on these measurements I concluded that the system was Operating in a slightly surchm'ged condition and thus did not qualify for a HAA certificate. Because of the adverse climatic conditions at the time the system was tested and the fact that the owners reported never having any backup problems in the 6 1/2 yem's they had lived there, I agreed to recheck the fluid levels after a month had elapsed to see if there was any significant change. I returned to the property on May 5, and was quite surprised to find the standpipes in both trench segments essentially di'y. We then went back on May 12 ~ 13 to conduct a second adequacy test of the wastewater disposal system. Within the first 100 gallons the fluid level in the upper trench standpipe rose 31 inches, but then remained essentially unchanged as the remainder of 1003 gallons of water was addext to the system over a two day period. I interpreted this behavior as indicating that the fluid level in the upper U'ench had risen to a point where it was spilling over into the lower trench. In the lower u'ench the fluid was flowing into a gravel zone below the level of the bottom of the standpipe. These test results indicate that in a one month period the wastewater disposal system had gone fi'om a surchm'ged condition to a non-surged condition with a surge capacity in excess of 700 gallons. During this period the house had remained occupied and the system had not been pumped, so the only apparent difference was that the trenches were no longer intercepting snowmelt. Because the well yield was too low to allow us to completely fill the system dm'ing the second test, the adequacy dete~znination was made on the basis of the excess surge capacity above the design daily flow rate. If, after review of our test data, yon concur that the system is adequate, we would appreciate your issuance of the requested HAA certificate. Please give me a call if you have any questions on this report. cc: Dennis and Donna Bash, c/o ReMax Properties. Sincerely, Ted Moore, P.E.
