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 howong=s`tem will function

Nitrate Advisory
Certificate of On-Site Systems Approval # OSC 171552
A Certificate of On-Site Systems Approval inspection and test of potable
water was recently conducted on the well water supply on Block 11, Lot 12
of Lake Ridge Terrace subdivision. This inspection revealed a nitrate
concentration of 11.8 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.

Water Well Advisory
Certificate of On-Site Systems Approval (COSA) # OSC 171552
During a recent COSA on-site inspection and test of the potable water
supply well on Block 11, Lot 12 of Lake Ridge Terrace subdivision, the
well's productivity was determined to be .39 gallons per minute. The
minimum well productivity required by this Department (AMC 15.55) for a
3-bedroom residence is .31 gallons per minute. Although the subject well
currently exceeds this minimum requirement, all parties concerned are
advised that the production capacity of the well may fluctuate. Restriction
of non-critical water uses such as washing cars and watering lawns and
gardens may be required.
This advisory must be attached to all copies of the subject Certificate of On-
Site Systems Approval.
