The installation was inspected and approved by the Municipality of Anchorage. The inspection report states the absorption trench is located 96' from the well on the lot. The Municipality apparently determined at the time that a waiver of the 100' setback was not required. It has been determined that a waiver is now required to allow the absorption trench to remain in its current location less than 100' from the well. Only the westerly 10' of the absorption trench is constructed within the 100' radius. The trench is located downslope from the existing well and any effluent that might surface from the septic tank would flow away from the well and toward the back of the lot. The surface grade is 2% to 5% away from the well. Surface effluent contamination of the well is virtually impossible. Underlying soils on the lot are silty gravels (GM) based on documentation completed during construction of the septic system. The well on the lot is 116' deep and the static water level has been measured at 67.4' below the surface. In addition, a recent water sample shows no coliform contamination and only 5.27 milligrams per liter of total nitrate/nitrite content. The well log is included for your review along with the water sample results and an as built showing the location of the existing absorption trench showing its proximity to the well. We are confident based on the long term performance of the existing septic system and the water quality from the well that contamination from the absorption trench is not likely. We therefore recommend that the waiver allowing the existing aborption trench to remain 96' from the well be granted.
