Mr. Williams:
Due to changes Jn the original construction plan for the
referenced property it is necessary to submit a revised on-site sewer
and water system design fer your information. Specifically the
changes consist of the following:
Let line setbacks required the proposed building be rotated
90 degrees from the orientation shown on the original
submittal.
2 The owner has elected to relocate the well location shown
originally.
3 The owner has elected to increase the number of bedrooms from
four to five.
As a consequence of these changes it was necessary to excavate a
third 'Lest hole and to change the system clesJgn from a bed absorption
system to a 5-ft shallow trench. The attached information reflects
these changes.
Due 1:o the lack of fine soils in the upper portions of the test
holes, the trench sidewalls are unstable and substantial sloughing
may take place. Z propose installing a 4-ft gravel depth below the
perforated pipe if possible, however, if this is not feasible, a
shallower grave] depth will be used. Consequently, the submitted
design reflects various gravel depths from three to four feet.
Conservatively, the longest anticipated trench length is shown on the
drawings.
While excavating TH-3 a soil sample was collected from an
approximate depth of 12 feet below ground ]eve]. A sieve analysis
indicates the material is a very gravelly olean sand. With this
Mr. Jim Williams, DHHS. Permit SW960057
L78, T'I2N, R3W, S15, Revised Dsgn, April 26, 1996, Page 2 of 2
sieve Z am requesting an approval to use the existing subsurface sand
in lieu of the required filter sand. As shown on the attached soil
log for TH-3, the sand makes up the bottom five feet of the test hole
and is greater than two feet in thickness. Due to the homogeneity of
the soils and subsurface conditions found in the three excavated test
holes, and their consistency with a test hole excavated on the
adjoining lot, it is reasonable to suspect there is no new
groundwater information to be found during a seven-day monitoring
period. Therefore, this submittal is being made with only three days
of mon'itoring.
Zf you should have any questions, please call. Although
be out of town until May 11, my receptionist will forward all
messages.
I will

5. STATEMENT OF INSPECTION BY ENGINEER
As certified by my seal affixed hereto and as of the validation date shown beloq I verify lhat 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 struclure indicaled
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.
ln conducting an adequacy test, I attempt to provide a thorough, conscieniious engineering analysis of the system in accordance with MoA
COSA guidelines and regulations. The reported resulls describe the perfonnance of the system under the mnditions encountered at the lime
of the test, and separalion distances measured to readily identifiable features. The operational life of all wells and seplic systems depend orr
the local soil conditisn, ground water levels that may fluctuate during lhe yeal and the water usage of the family being served by the system.
These conditions are oulside the control of the evaluator of this system. All systems eventually fail and satisfactory test results do nol
guarantee future performance of the systern, nor do they guarantee that lhere are no hidden defects or encroachments. Therefore we cannot
provide any waranty for future performance, nor €n we estimale remaining life of the system. The content of this report is for the sole
benefit of the owner listed above. Reliance on this report by anolher person is at their own risk. Pannone Engineering Services LLC highly
recommends buyers hire their own engineer to evaluate this report.

Nitrate Advisory
Certificate of On‐Site Systems Approval # OSC201467
Subdivision: T12N R3W, Section: 15, Lot: 78
A water sample revealed a nitrate concentration of 5.62 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. 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.
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.
