Box 196650 Anchorage, AK 99519-6650 Subject: Upgrade Sewer Permit—McMahon #2 B7, L8 It has been determined that the absorption field of the subject property is saturated. Subsequently, the owner has requested we proceed forward to obtain a septic permit to upgrade the septic system. The general slope of this lot is from east to west at a grade of approximately 3-5% over the septic area. On May 12, 2017 a testhole was performed to investigate soils and groundwater. The results of this test are attached for your review. The proposed upgrade will serve the existing 3-bedroom single-family residence. We propose to install a 47' long deep trench. Groundwater was not encountered at excavation or at monitoring. The property and adjacent lots are served by private water. There is no surface water within 100' of the proposed system and there are no known curtain drains within 50'. We do not expect there to be any adverse effect on adjacent lots by the development of this system. If you have any questions, please contact me at 868- 3791 / FAX 868-3793.

DUFFUS Date 6/1/2017 THIS COSA DOCUMENT CANNOT BE USED TO TRANSFER TITLE UNLESS ALL VENDORS(ENGINEERING,SURVEYING,CONTRACTORS,ETC...ASSOCIATED WITH THIS COSA ARE PAID IN FULL AT OR BEFORE CLOSING. 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.

This inspection revealed a nitrate concentration of 9.83 milligrams per liter (mg/L) was reported for the property's well water sample. The Environmental Protection Agency (EPA) has established a maximum contaminant level (MCL) of 10.0 mg/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. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate. This advisory must be attached to all copies of the subject Certificate of On- Site Systems Approval. Nitrate Fact Sheet From Northern Testing Laboratories,Inc. Nitrate is a negatively charged compound of nitrogen and oxygen, which is very soluble in water. Nitrate is not readily filtered or otherwise removed in the soil and can pass rapidly into ground water wells. SOURCE: Nitrate is a major component of fertilizer and wastewater. Often the nitrate is in the form of ammonia or protein first, which through contact with oxygen and certain bacteria, converts to the oxidized form known as nitrate. Sources of nitrate from wastewater include urea, ammonia cleaners, food solids, and bacterial cells. It may also result from the breakdown of organic matter buried in the soil. TOXICITY: Nitrate is generally not toxic to adults or children over the age of two or three years, but is associated with a potentially fatal infant disease called methemoglobinemia. In the digestive system of young children, nitrate converts to nitrite, which can pass through the intestinal wall into the blood stream. There it combines with the hemoglobin and interferes with the ability of the blood to carry oxygen. For this reason, methemoglobinemia is referred to as "blue baby" disease. The EPA limits the concentration of nitrate in public drinking water supplies to 10 mg/L. The standard has been lowered from a previous level of 45 mg/L set by the US Public Health Service and the World Health Organization. TREATMENT: due to its solubility in water and negative ionic charge, filtration and other common home water treatment systems such as softening or iron filtration does not readily remove nitrate. The best method for limiting nitrate in well water is source control. This can include avoiding overdosing of fertilizer near the well and maintaining good separation distances between septic tank leach fields and the well. A special anion exchange filter that contains a media with a strong affinity for negatively charged ions in water, or by a reverse osmosis treatment system or distillation can remove nitrate. TESTING: Nitrate analysis is usually done by one of the several "wet chemical" methods using a spectrophotometer to read the final color endpoint. Specific ion electrodes also can be used to detect the activity of nitrate in water. This laboratory uses several different wet chemical methods approved under the public water supply laboratory certification program. They also have test kits available, which the laboratory uses to perform an inexpensive "screening test", and with which the homeowner can monitor the change in nitrate levels from their well. They recommend comparing the test kit results against a certified analysis from the lab occasionally to verify the accuracy of the kit. We recommend using a specially prepared bottle that has been rinsed in hydrochloric acid for collecting samples. %r .,......, -4- l / S S9 �' JJ.F W / O'/ A �/ B / / . ,s. , , Z/ / ,! / '� 0 H.
