This inspection revealed an arsenic concentration of 55.6 micrograms per liter (ug/L) for the property's well water sample. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 ug/L for public drinking water systems. While private wells are not subject to this regulation, EPA standards are based on existing health information and can therefore be used to gauge the relative quality of water from private wells.

This waiver approval applies to the existing absorption field only.

The installation was inspected and approved by the Municipality of Anchorage. The inspection report states the absorption trench is located 100' from the well on the lot. Unfortunately a recent surveyor as built indicates the well is only 97' from the east end of the trench. 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 easterly 3' 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 trench 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 348' deep and the static water level has been measured at 143' below the surface. In addition, a recent water sample shows no coliform contamination and no trace of total nitrate/nitrite content a good indicator that the absorption trench has no effect on the water quality. 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 illustrating 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 97' from the well be granted.
