Therefore, this vertical separation distance needs to be enfarced dwing construction. 2.

DUFFUS Date lxl251-v 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.
