Soils: A test hole was performed on this lot by Pannone Engineering Services, LLC on 10/13/2020. Groundwater was not observed during the excavation of the test hole, and bedrock was not encountered. No groundwater was observed in the test hole monitor tube after 7‐days. The test hole on lot 10 was found to have a percolation test result of 3.7 minutes per inch. 27 test holes were performed in this subdivision by PES for the approval of the subdivision, and more were performed during the design of septic systems on lots in the subdivision.  No groundwater has been observed in the subdivision.  Bedrock was not encountered anywhere in the subdivision. The test holes in the area were all found to have a percolation of less than 5 MPI, some less than 1 MPI. See soils logs for subdivision, S12577.  The test hole on lot 10 was performed further to the north than the system will actually be installed.  We are using surrounding test holes as a justification. Based on the results of the surrounding percolation tests and known soil types in the area, per 15.65.210 C; a conservative application rate of 1.2 gallons/day/square feet was used for a conventional wastewater system. 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. 4. Topography: See attached site plan for area topography. There are no steep slopes in the area of the drain field. 5. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is complete and no further comments are received from MoA On‐Site Department, the note will be removed and “For Construction” drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. If you have any questions or concerns, please contact me at (907) 745‐8200.

In conducting an adequacy test, I attempt to provide a thorough, conscientious engineering analysis of the system in accordance with ADEC & MOA guidelines and regulations. The reported results describe the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily identifiable features. The operational life of all wells and septic systems depend on the local soil condition, ground water levels that may fluctuate during the years, and the water usage of the people served by the system. These conditions are outside the control of the evaluator of this system. All systems eventually fail, and satisfactory test results do not guarantee future performance if the system, nor do they guarantee that there are no hidden defects of encroachments. Therefore, we cannot provide any warranty of future performance, nor can we estimate the remaining life of the system. The content of this report is for the sole benefit of the owner listed above.
