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.

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 for this application,
shows that the on-site water supply and/or wastewater disposal system is (are) safe, functional and adequate
for the number of bedrooms and type of structure indicated herein. I further verify that based on the information
obtained from the Municipality of Anchorage files and from my investigation and inspection, the on-site water
supply and/or wastewater disposal system is(are) in compliance with all applicable Municipal and State codes,
ordinances, and regulations in effect at the time of installation.

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. OF Az�

Nitrate Advisory
Certificate of On-Site Systems Approval # OSC 171206
A Certificate of On-Site Systems Approval inspection and test of potable
water was recently conducted on the well water supply on Block 7, Lot 6 of
McMahon #2 subdivision. 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.
