Subject: New sewer/well permit - Glenn View S/D, Lot 2
Gentlemen:
On June 13, 1997, we excavated two new testholes for the subject property. There is
one previous testhole which was dug during the preliminary plat process, however
it was not suitably located for the four bedroom house which is proposed for this lot.
The results of these tests and water monitoring are attached.
We propose to install a 2' wide deep trench. Although the original testhole
indicated no water, we did find some water in testhole #2 which is located in a
lower portion of the lot and we do not feel is representative of the site. Additional
fill will be placed over the system to provide a minimum of 3' of cover when
complete.
There are no public or private wells within 200' of our proposed system location
except as noted. There is neither surface water within 100' nor any curtain drain
within 50'. We do not expect that there wilt be any adverse effect on adjacent lots by
the development of this system.
If you have any questions, please contact me at 696-6111/FAX 696-8111.

Comments: This investigation was completed in compliance with MOA guidelines, regulations,
and best industry practices / methods. 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 in land use,
local soil characteristics, groundwater levels that may fluctuate during the year, quality of
construction (workmanship & materials), the water usage of the family being served by the
system and maintenance. 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, any estimate of how long a system will function satisfactory
for current or future occupants or guarantee that no unseen encroachments, deficiencies or
discrepancies exist can be given by First Water Consulting & FWCS

Nitrate Advisory
Certificate of On -Site Systems Approval # OSC 221148
Subdivision: Glenn View Estates lot 2
A water sample revealed a nitrate concentration of 6.6 milligrams per liter (mg/Q.
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.
MaUmg�Address P O Box 196650 * Anchorage,$Alaska 99519 6650 *www mum org
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.
