Box 112809 Anchorage, AK 99511 Dear Mr. Schadt: June 3, 1994 14530 ECHO ST, ANCHORAGE, ALASKA 99516 RECEIVED JUN 7 1994. D Mu(~icipahty of Anchorage ept. Health & Human Ser~iices You have requested that I provide you with a written response to yo;u' letter of May 10, regarding the septic system serving the McConnell residence on Lot 9, Block 2, Kasilof Hills S/D. Let me begin with a summarization of my involvement with this property. I was first contacted by Mr. Thompson (the former owner) on May 13, 1993, at which time he requested me to conduct adequacy tests of the water supply and wastewater disposal systems and file an application for a Health Authority Approval (HAA) certificate. He gave me no reason to suspect that the system had recently been tested by others who had concluded that it was in a state of failure. Mr. Thompson did inform me that the tank had been recently pumped and offered to pump it again, but I told him that my experience had shown that pumping a system just before it is tested does not help it to pass the adequacy test, and often makes it more time consuming to test. We conducted our adequacy test of the system on May 15-16, 1994. My report to Mr. Thompson dated 6/7/94 and letter to John Smith at the Health Department dated 12/3/93 with accompanying copy of our field data sheet (I believe you are itl possession of all of these) describe om' testing procedure in some detail, so it should not be necessary to rehash that information in this letter. Health Department guidelines stipulate that a system is considered passing if it is able to absorb 150 gallons of water per bedroom per day when filled to a depth of less than or equal to the effective gTavel depth, which is 5 feet in this case. Our measurements demonstrated that on the date of om' test the system did absorb water at a rate slightly faster than that specified by the Health Depm'tment, when tested in compliance with the above guidelines. The fact that the test was conducted during breakup, when snowmelt was also being absorbed into the gn'ound, gave us an added level of confidence in the results we measm'ed. Based on our field measurements we had no basis upon which to fail the system, so we submitted the HAA application to the Municipal Health Depm'tment. As Dan Roth (an engineer from the Health Department who reviews and signs off on HAA certificates) stated in the 5/17/94 meeting on the property attended by you, Mrs. McConnell, Mr. Roth and me, in his opinion our data indicates that the system was passing on the date of our test, and that I took the appropriate action in signing off on the adequacy of the system. At the time I submitted our application for a HAA certificate to DHHS, I had no knowledge that your clients had also submitted to the Health Department a letter from S & S Engineering stating that they had recently concluded that the system was in a state of failure. No~mally, when the Health Department is presented with conflicting opinions, they conduct an investigation and discuss the conflicting test data with both the engineers. For reasons which are not clew' to me, they did not do so in this case. At out' meeting on 5/17/94 Mr. Roth indicated that Mr. Bolles did visit the property prior to signing off on the HAA certificate, and did satisfy himself that the fluid level in the sump was consistent with a passing system. On June 4, prior to signing off on the HAA certificate, Mr. Bolles called me with a question about the depth to bedrock in the well, but he did not mention m~y concern about the adequacy of the septic system. My first indication that anyone had framed a different opinion about the adequacy of the system was on June 7 when I got a phone call from Mm'y Cox (one of the Realtors), who was upset about the fact that Mr. Thompson had already taken the recently issued HAA certificate to the bank and gotten his escrow money released. By this point the Health Department's decision had akeady been made to issue the HAA certificate, so it was too late to do further investigation. I discussed our test procedure and results with Ms. Cox, and said I would ask my client, Mr. Thompson, about releasing a copy of my repo~t to Ms. Cox. I then called Mr. Thompson who admitted that there had been an earlier test, but expressed unhappiness about the way the earlier test had been conducted Mr. Thompson ascribed the controversy to "a real estate deal gone bad" and specifically requested me not to send a copy of my report to Ms. Cox. Since Mr. Thompson was my client, it was his option to decide to whom our report would be released. I heard no mom from anyone on this matter until December 3, when I received a call fi'om John Smith at the Health Department requesting a copy of my adequacy test data, which I provided to him the next day, along with a cover letter describing my test procedure. On December 14, I called Dan Roth to inquh'e about the status of this issue, and he told me at that time that based on om' adequacy test data he felt we had no choice but to pass the system. He did state that based on his recent field inspection he felt the system was no longer functioning adequately. The next thing I heard was your letter of May 10, which led to our May 17 meeting at the property with Mrs. McConnell and Dan Roth. On that date the fluid level in the sump was significantly higher than it had been during our test a year previously. There did not appear to be any leaking fixtures to account for the system being sm'charged. Because Mrs. McConnell said she had been using a lot of water innnediately prior to om' meeting, I offered to re-check the fluid levels later, to see if there was any significant difference. Since then I have stopped by a couple of times, and the fluid level in the trench has been approximately 10 inches lower, but still in what appears to be a slightly surchm'ged condition. This current fluid level is also significantly deeper than the fluid level measm'ed by S & S prior to the stm't of theh' test. On both of my subsequent inspections there has been a visible trickle of water flowing into the trench fi'om the septic tm~, but I had no way of determining how much, or where the water was cotrdng from. The system does appear to be still able to absorb the wastewater flow fi'om the residence without overflowing onto the surface of the ground or backing up into the septic tank. As confirmed by the Health Department, our field data indicated that the system was functioning adequately on the date of our test, wtfich is all that an engineer can adch'ess when conducting an adequacy test. Om' test data does not give reason to suspect any tampering with the system dm'ing the com'se of om' test. It is unfortunate that the Health Depm'tment did not take further steps to resolve the conflicting adequacy test information that they were aware of prior to issuance of the HAA certificate. Mrs. McConnell stated to us in the meeting that Mr. Thompson had told her he periodically added at least some hych'ogen peroxide to the system. Had Mr. Thompson treated the system with large amounts of hydi'ogen peroxide between the dates of the two tests without telling us, this could have caused a short te~m improvement in the absorption capability of the system. The engineer would have no way of knowing that this had beea done, unless told by the client. There m'e a number of factors which cause all septic systems to eventually fail, including gradual deterioration with age, the rate of which is influenced by the quantity and clem~liness of wastewater emanating from the residence. It is possible that the differences in the operating levels observed this spring and last sphng are phmm'ily the result of this natural aging process. As I try to point out to all my clients, an adequacy test is like a snapshot in time, assessing the performance of the system under the conditions encountered at the time of the test and does not gum'antee future performance under different conditions. We t~ to be extremely careful in the conduct of om' tests, and believe we have em'ned a reputation for accurate and conscientious work. I sincerely hope that this lengthy report will resolve your concerns about the adequacy test which we conducted. Please feel free to call me if you have further questions. cc: Dan Roth, M.O.A.

I am also enclosing a copy of the report we sent to Mr. Thompson, the owner. When the owner requested us to do the adequacy test, he informed us that the tank had been pumped one week earlier. He offered to pump it again, but I told him this would not help the system pass the adequacy test. The owner did not inform us that another engineering firm had already tested the system and concluded that it was in a state of failure. I only found this out from the buyer's Realtor after the HAA certificate had been signed and turned over to the owner. As is true when any engineer tests a septic system, there is no way to be absolutely sure that the owner hasn't treated the system with hydrogen peroxide or taken other steps to try to improve its apparent performance. We have, however, been doing these tests for long enough that we can usually tell when someone is trying to deceive us. According to the as -built inspection report, the trench has 5 feet of sewer gravel beneath the distribution pipe. At the start of our test, the fluid depth in the sump at the end of the trench was only 10 inches, consistent with the system's having recently been pumped. The addition of 728 gallons of water brought the fluid level up another 36 inches, to a total depth of 46 inches. Once the flow of water was stopped the fluid level did recede, but not at an adequate rate for a 4 bedroom residence. We then added additional water to bring the total fluid depth up to 64", or roughly the top of the horizontal distribution pipe. We then let the system sit overnight, during which period the fluid level receded to a total depth of 46 inches. The next day we added water to bring the fluid depth back up to a total of 60 inches, or roughly the level of the bottom of the horizontal distribution pipe. We then monitored the reabsorption rate over the next hour, and concluded that the system was absorbing water at a rate corresponding to 617 gallons per day, when filled to just below the level of the horizontal distribution pipe. (Another way of looking at the data would indicate a rate of 720 gallons per day). Based on our test data we concluded that the system was functioning adequately for a 4 bedroom residence. The fact that our test was conducted during breakup (there were still patches of snow in the area of the septic system) made us less concerned about the relatively slow absorption rate. As you know, a great many systems in Anchorage would not pass an adequacy test conducted in the middle of breakup. K / a a f CIVIL & ENVIRONMENTAI.

Both from her and from a subsequent conversation with the seller, I received the impression that there was a great deal of mutual distrust amongst the various parties to the transaction. Mr. Thompson felt that the original test was improperly carried out so as to force him into paying for an upgrade. I never had an opportunity to review the field data from the original test, however, in re -looking at our own data I still think that it supports the conclusion we reached. If you care to share with me your field measurements and the field data from the earlier test, I would be happy to provide you with my interpretation of them. We go to some lengths to ensure that our test procedures are in accordance with DHHS standards. Are you sure that the system is presently surcharged?, and did you check to be sure there is not a leaking fixture in the house?

Box 110609 Anchorage, AK 99511 Dear Mr. Thompson: Per your request on May 15 - 16, 1993 we conducted adequacy tests of the water supply and wastewater disposal systems serving your residence on Lot 9, Block 2, Kasilof Hills S/D, located at ;:,-10072 Stroganof Drive. I understand that you have already picked up the Health Authority Approval (HAA) certificate from the Municipality. We were unable to locate a driller's log for the well serving this residence, however other documents on file at DHHS indicate that it was probably drilled in 1974. On the date of our test the static water level stood at 28 feet below the top of the casing. During the course of our test we pumped a total of 728 gallons of water from the well at the maximum pump output of 6 gpm, wlhich caused the water level inside the casing to be drawn down to 32 feet, but no further. her. Based on our test data we determined that the total yield of the well is in excess of 6 gpm, which exceeds the Municipal criteria for approval of a single family residence, and also meets the FHA criteria that a well be able to supply 720 gallons of water within a 4 hour period. Water samples collected on May 13 were satisfactory, showing 0 coliform or other bacteria per 100 ml., and 3.83 mg/l of nitrate -N. According to the as -built inspection report on file at die Municipal Health Department, the original wastewater disposal system was installed in November of 1974, and consisted of a 1250 gallon septic tank followed by a 27 foot long temporary drainfield. In 1977 the system was upgraded by the addition of a 62 foot long soil absorption trench containing 5 feet of sewer gravel. To assess the adequacy of the system we ran measured quantities of water into the system through the sump at the end of the trench, while monitoring fluid levels in the septic tank and in the soil absorption system standpipes, before, during and after the flow of water was stopped. The initial fluid depth in die sump at the end of the trench was 10 inches, indicating that it had probably been recently pumped. The addition of 728 gallons of water into the system caused the fluid level in die sump to rise 36.5 inches, and after the flow of water was stopped the fluid level receded at a quite slow rate. This behavior is consistent with the system having been recently pumped, so this dose of water was just refilling the less permeable lower portion of the trench. We then added another 258 gallons of water to completely fill the trench and let it sit overnight. The next day we again added water to bring the fluid depth in the sump at the end of the trench back up to 60 inches (the reported gravel depth), and then monitored the reabsorption for an hour after the flow of water was stopped. Based on our test measurements we concluded that the trench absorbs water at the rate of 617 gallons per day when the fluid depth is just less than the gravel depth; this measured absorption rate is slightly over the design rate of 600 gpd for a 4 bedroom residence. At no time during our test did the fluid back up into die septic tank, or even into the invert of the cleanout pipe near the upstream end of the trench. In conducting an adequacy test we attempt to provide a thorough, conscientious engineering analysis of the system. The reported results describe the performance of the system under the conditions encountered at the time of the test, and the separation distances are measured to readily identifiable features. Septic systems do deteriorate over time and satisfactory test results do not guarantee future performance of the system under different conditions, nor do they guarantee that there are no hidden defects or encroachments. You should recognize that the system was tested during during breakup, at a time of the year when soil conditions tend to be saturated with snowmelt. Many absorption systems do not exhibit as good a performance when tested during breakup as they would if they were tested during a drier time of the year.
