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 r!�' system will function satisfactory for current or future OF occupants or can ArcTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist. �* 4 * �. 5.

Box 770617 Eagle River, AK 99577 RE: fIAMANN S/D, ADD //1 LOT 5, BLOCK 1 Dear Wilma, Per your request, we have inspected the on-site water and wastewater systems of the above referenced property. This investigation was based on observations of the day in which the septic adequacy was performed, information from others and available Municipality of Anchorage (MOA) record documents. Based on the above information it appears that the property was developed between 1958/59 and no record documents of the existing systems were. found at ADEC or the Municipality of Anchorage (MOA). This is not uncommon for this area within the time this property was developed. The property has an existing single-family 5 -bedroom I -story structure with a walk out basement. The property is served with a 1500 -gallon septic tank with crib disposal field and a spring fed concrete cistern (see attached photos). Discussions with DSD Staff indicate that since it is not a well they can not certify the system even though the water meets current water quality standards. Others performed the water quality testing, with a sample collected on September 21, 2009, and attached to this report. On October 13, 2009 the septic adequacy test was performed. Prior to testing JRs Pumping pumped the 1,500 -gallon septic tank. The absorption field monitoring tube was dry at the start of the test and 750 gallons of water were added at the monitoring tube. The septic field readily absorbed the water and was dry at the end of the test. The system absorbed the required amount of 150 gallons per bedroom per day for a 5 - bedroom residence. It is my opinion that the system's absorption capacity exceeds that of a 5 -bedroom house. It appears that the existing, undocumented septic system is sized as a 5 -bedroom system. Feld measurements were taken and a testhole performed by Doug Kenley, PE documents that the system does not encroach bedrock or ground water. Please see attached drawings. The septic tank is approximately 95'+/- to surface water (see attached as -built) and conforms to separation distances required at the time of installation from the information obtained from municipal records. Presently the tank is less than 5 feet from the building foundation, but met the current separation distances ` Al2CT1:1Z1ZA CONSULTING, INC If 212 E. 51° Ave, Anchorage, AK. 99503 f Office (907) 868-3791, Fax (907) 868-3793 October 13, 2009 Wilma Hamann P.O.

An in -floor drain within the structure acts as a cleanout for the mainline in the house to the tank. All other separation distances conform to present code requirements. From available data and visual observations, it appears that this system poses no health or safety threat to adjoining properties or other individuals. The assessment of the condition of the septic applies only to the conditions as of the day tested. The 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 and the water usage of the family being served by the system. The operational life of all septic systems is subject to these various and dynamic characteristics and are outside the control of the evaluator of the septic system. Therefore, ArcTerra cannot give any estimate of how long a system will function satisfactory for current or future occupants nor can ArcTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist.
