CERTIFICATION & STATEMENT OF INSPECTION BY ENGINEER As certified by my seal affixed hereto and as of the validation date shown below, I verify that my investigation, based on procedures outlined in the Certificate of On -Site Systems Approval Guidelines, indicates that the on -site water supply and/or wastewater disposal system appears to comply with applicable Municipal and State codes, ordinances, and regulations in effect at the time of installation, unless noted otherwise. Name of Firm Arcterra Consulting Phone (907)-696-6111 Engineer's Printed Name Kenneth Duffus Date // J0.r.3 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 evaluatorv_ of the well and septic system. Therefore, ArcTerra can not give any estimate of how long a system will 0— function satisfactory for current or future occupants or can ArcTerra guarantee that no unseen encroachments, deficiencies or discrepancies exist. COSA Checklist June 2022 Well Water Advisory Certificate of On -Site Systems Approval # OSC231376 Subdivision: SPRING CREEK TR A, Block: , Lot: This well's productivity was determined to be 0.5 gallons per minute. The minimum well productivity required under (AMC 15.55) for a 3-bedroom residence is 0.3 gallons per minute or 150 gallons per day per bedroom. Although the subject well currently exceeds this minimum requirement, the production capacity can fluctuate and may be insufficient to meet your needs. Water storage is provided.

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. Since nitrates are known to slowly increase, we recommend you monitor the water quality. Please see the attached "Nitrate Fact Sheet" for important information regarding nitrate.

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. iVII unicipaMy of A.ndhorage Community Development Department on-S;te Water & Wastewater Prograrn 'i. 00 Lima St. u P.O.

Box 196650 Anchorage, AK 99519-6650 Subject: SPRING CREEK TRACK A- Well Inspection During our mid -September field inspection for a COSA approval for this property sale, we took water samples of the 2 wells on the subject lot and submitted these to SGS Laboratories for testing. The lab report on the nitrate samples came back at 12.3 mg/L from the north well, and 21.1 mg/L from the southern well. We immediately called Sullivan Water Wells and requested they scope the well, to a depth below 40 feet and down to the static water level if possible, as suggested in the COSA Guidelines 2018 addition (8.c.i). Their report found no anomalies inside the casings that would lead to elevated nitrate levels. At the time of the inspection there was no visible sign of water intrusion into the wells. Static water level of the north well was found to be at 46.4' and 168' for the south well. Our field inspection of the site shows the well casings extend above grade 2' for the north well and 1' for the south well, all the area around the wells drains away from the wells, meeting the guideline 8.c.ii. The north well was drilled in 1992 to a depth of 185 feet and meets the construction standards in place at the time of construction, guideline 8.c.iii. This well consists of 46' casing in gravel soils and bedrock from 46' to 185' and the casing is lined from 40 foot to the bottom of the wellbore meeting the current rehabilitative guidance 8.c.v. The south well is not producing enough water to help sustain the property and is older, much deeper, and has the higher nitrate levels. Currently, it is the owner's intent to de -commission the l -well. Historical records in the area, as shown on the MOA nitrate mapping per the date of this letter, indicate no other nitrate information within 800' since 2007. While this well water has been tested for nitrates in 2005, with nitrate levels of 7.38, the residents of the property have not noted any adverse effects. If you have any questions, please contact me at 696-6111/FAX 868-3793. Respectfully submitted, ArcTerra Consulting, Inc. Kennet M. fus. P.E Attachments: Sullivan Water Wells Report dated 9/20/23
