Dear Mr. Robinson,
Attached with this cover letter are sheets 2 & 3 of 7 of the on-site septic design for the
above noted lot. They have been revised, per our 10/17/94 telephone conversation. I
have increased the length of the drainfield to accomodate a two bedroom house, per
Municipal regulations.

Re:
Lot 18B
Lakewood Hills Sub.
Site NarratiVe
The following narrative is for the On-Site Septic Upgrade of the above noted lot. The lot
is located between Abbott Loop Rd. and O'Malley Rd., on Hillside Drive. Access to the
lot is directly off Hillside drive. The Lot is locate in Sec. 14, T12N, R3W.
The general topography of the lot is fairly flat for the portion, approximately .6 Ac, which
has been improved and developed. The house is sited at the approximate half way point
of the lot, east-west, and north-south. The mid portion of the lot has been cleared, and
landscaped. The natural flora of the lot tends to be small Birch and some White Spruce,
which would indicate that the lot soils are fairly free draining. The lot drops off from the
house site to the south into a draw, which is free of standing or flowing water. The lot
to the south, also owned by the Bumgarners is undeveloped. The north side of the lot
climbs in elevation for approximately ten to fifteen feet to the neighbors house. The
ditches on Hillside drive appear to be substantial, and direct run-off away ~rom the lot.
The lots to the west are undeveloped. The developed lot to the north is more than 100'
from any point on the proposed system. There can therefore be no conflict with the well
on this property nor can the system interfere with the protective radiuses of the lot to the
north.
The existing system, installed in the early 1960's was in place prior to the subdivision of
the lot into Lot 18B and Lot 18A. The proposed syStem will observe all lot line offset
restrictions, and bring the property into compliance with the latest regulations.
~he well on this property is approximately 82! from the existing concrete septic tank. The
· .p..~0posed Septic tank will be placed outside the 100' protective well radius, and the
existing tank abandoned in place. The existing Icg crib drain field will also be abandoned
in place.
No adverse impacts from the upgrade of the septic system for this lot are forseen.
Sincerely,
Wright-Alaska Engineering Services

Percolation Test Rate Adjustment
All percolation tests conducted for this project have been completed using a 4"
diameter tube in a 6" diameter hole. The annular space between the tube and the
hole walls is filled with 3/8" pea gravel.
The following adjustment has been made to all readings to account for the volume
occupied by the annular gravel pack.
h:=8
d := 5.25
h-d
-- - 0.344
h
P :- 0.344
The porosity of the gravel has been determined using two
identical 64 oz. containers. One filled with water, the other with
gravel. The depth of water (h) was measured. Water was
poured into the gravel container. The depth of the remaining
water was measured. P= (h-d)/h.
The correction factor 'R' was calculated using the formula from page 76 of Dr. O.
Benjamin Kaplan's book "Septic Systems Handbook":
r1 :=2

r2. r~ = 1.5
radius of 4" diameter perc tube

R= V1N2 where V1 is the total water vol. in the hole, and V2 is water volume with no
gravel.

Nitrate Advisory
Certificate of On-Site Systems Approval # OSC181251
Subdivision: Lakewood Hills, Lot: 18B
A water sample revealed a nitrate concentration of 6.9 milligrams per liter (mg/L).
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.

5. 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 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.
In conducting an adequacy test,I attempt to provide a thorough,conscientious engineering analysis of the system in accordance with MoA COSA
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 year,and the water usage of the family being 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 of the system,nor do they guarantee that there are no hidden defects or encroachments.Therefore we cannot provide any warranty
for future performance, nor can we estimate remaining life of the system. The content of this report is for the sole benefit of the owner listed
above.
