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 in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. 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, any estimate of how long a system will function satisfactory for current or future occupants or guarantee that no unseen encroachments, deficiencies or discrepancies exist can be given by First Water Consulting & FWES 6.

Box 196650 Anchorage, AK 99519 REF: Lot 13 Caulkins Dear Mr. Morris: On behalf of my client, Mr. Scott Marshall, I am submitting the information necessary for your determination of a waiver of separation distance, well to septic tank, to 71' for the above-referenced lot. The septic system absorption rate has been tested and found adequate for a 2 bedroom use. The septic system was installed in 1975 by Maus Excavation and was inspected and approved by the Municipality at that time, as per the inspection report enclosed. A later request for final approval shows the well to septic tank distance as 70' Our field measurements confirm the tank inlet to be at 71' from the well. The enclosed well log shows that the well draws from an aquifer at a depth of 337-343'. The casing is continuous to 343' where it draws water from a sand and gravel layer. The surface topography is such that any seepage would be directed away from the well location at a 5% slope in all directions. The subsurface soil is rated a GP type With a perc. rating of 200. The well log shows 3 protective soil layers, one at 20-35' (hardpan), the second at 175-200' (clay and gravel) and a third at 270-337' (clay and gravel with boulders). A water sample for coliform bacteria was satisfactory. The area in question has a low population density. If there are any questions or if additional information is required please feel free to contact me at 694-5195. Sincerely, Lou Butera, P.E.

' The septic tank was pumped and verified to h~ve a capacity of 1000 gallons. The seepage trench was tested by a continuous flow of water over a period of 48 hours. It vas initially charged et a rate of 0.7 of a gallon per minute for a total of approximately 1000 gallons. During the second 24hour period approximately 370 [mllons ~ere added to the trench with a 0 rise in the water level in the sump ,t the end of the trench. On the basis of the above test it can be conhluded that the system is operating adequately for the two bedroom residence.
