CITY OF MERIDIAN
CITY OF MERIDIAN
MUNICIPAL WATER SUPPLY WELL NO. 16-A EVALUATION AND RECONSTRUCTION
DESIGN, INSPECTION, AND GEOTECHNICAL SERVICES
PROJECT UNDERSTANDING
City Well #16-A has served the City continuously for 19 years. A recent evaluation of the well
by Hydro Logic, Inc., revealed that the well's steel casing is highly corroded and the well is
near the end of its useful life. In addition to the deteriorating well casing, the ground water
produced from the well contains elevated concentrations of radionuclides slightly above
regulated limits for Public Drinking Water Systems such that its current use beyond fire-
protection services is restricted. In advance of replacing the well, the City conducted several
experiments and hydraulic tests using the existing well and had an exploratory tesVmonitoring
well drilled and constructed. Hydro Logic, Inc. interpreted these studies and has made
recommendations to the City. Hydro Logic, Inc. presented several options to the City for a
replacement well program, one of which is to attempt to reconstruct the existing well. The
following task order contains a description of the work tasks necessary to accomplish the
reconstruction, and/or proper abandonment of the well if reconstruction is not possible, along
with estimated costs for the professional hydrogeologic services, design, and project oversight
for the abandonment or reconstruction.

SCOPE OF WORK
TASK 1.1 -CITY WATER WELL NO. 16-B REGULATORY APPROVALS
Per the City's request, Hydro Logic, Inc. (Hydrogeologist) will: 1) Evaluate the City's water
rights appurtenant to Well #16-A, and any other existing City water right permits that could be
easily amended, to file an application to add a point of diversion to the Well #16 site. After
filing of the appropriate application, the Hydrogeologist will shepherd the application through
the process and respond to any additional requests for data by the Department of Water
Resources. This task includes one meeting with the Department of Water Resources.
The Hydrogeologist will also file the appropriate Applications for Drilling Permits or Modification
of a well permit for the reconstruction or re-drilling of the WeII #16-A.
The Hydrogeologist will develop and file an IDEO Well Site checklist, Well Construction PER,
GWUDI evaluation, and Waiver to setback requirements for the new well.
Estimated consulting costs for Task No. 1.1 is $ 6,800
TASK 1.2 -CITY NO. 16-B MONITORING WELL GROUND WATER SAMPLING
After receiving the initial ground water analytical results for the #16 Monitoring Well, two
additional depth zones of the aquifer were selected as potential target aquifers for a
replacement well on this site. Owing to the large expense of testing for the complete municipal
Safe Drinking Water Act suite of constituents, the expensive Synthetic Organic Compounds
were not tested for until major ion and radionuclide chemistry were known. The targeted
aquifers now need to be sampled and tested for the New Source Monitoring suite of analytes
from several zones of the #16 Monitoring Well. The Hydrogeologist will provide the sampling
pump, field instruments, calibration standards, sampling carboys, filter apparatus, and
appropriate preservatives to obtain the samples and transport the samples to an approved
laboratory and follow them through the process. Included in this task are the laboratory
analytical fees and geochemical modeling and interpretation by HLI's geochemist.
Estimated consulting costs for Task 1.2 is $ 12,800.
TASK 1.3 -CITY NO. 16-A SUPPLY WELL -REMOVE INSTALLED LINERS
In the determination of the root causes of the radionuclide problem at Well #16-A, three pipe
liners were installed to occlude selected intervals of the existing well completion interval. All
experiments are now concluded and these liners need to be removed from the well to facilitate,
either, proper abandonment of the well or its reconstruction. The Hydrogeologist will serve as
a liaison between the drilling contractor that installed the liners and the City during the work to
remove these liners. The Hydrogeologist will develop the Contractor's scope of work and cost
estimates for the City, and assist the City in scheduling, and directing the work on site, as well

HYDROLOGIC, INC Page 2 016
as reviewing and reconciling the Contractor's invoices. Hydrogeologist will assist the city in
arranging for building and site protection, and provide regular project updates to the City.
Estimated consulting costs for Task No. 1.3 is $ 2,700.
TASK 1.4 -CITY NO. 16-A SUPPLY WELL AQUIFER TEST
After the three liners are removed from the well, the Hydrogeologists will perform an aquifer
test using Well #16-A as the pumping well and the newly completed nine tube-wells of the #16-
B Monitoring Well as the observation wells. The test would be aimed at the determination of
which zones of the #16 Monitoring well are affected by the pumping of the existing well and to
what extent. This information may be valuable in determining the ultimate reconstruction or
new well design to ensure good water quality.
Estimated consulting costs for Task No. 1.4 is $ 4,150.
TASK 1.5 -CITY NO. 16-A SUPPLY WELL REMOVE WELL SCREENS
Following the aquifer test of the existing well, an attempt will be made to dismantle the well
screen assembly and remove it from the well by the selected selected contractor. The
Hydrogeologist will serve as a liaison between the drilling contractor that installed the liners
and the City during the work to remove these screens. The Hydrogeologist will develop the
Contractor's scope of work and cost estimates for the City, and assist the City in scheduling,
and directing the work on site, as well as reviewing and reconciling the Contractor's invoices.
The removal of the screened section will allow for one of two scenarios. The first and primary
goal would be to facilitate a proper well abandonment by restoring the natural stratigraphic
layering of the aquifer system interrupted by the well through the emplacement of grout seals.
The abandonment goal may be realized if only a partial section of the well screens can be
removed.
Estimated consulting costs for Task No. 1.5 is $ 16,300.
TASK 1.6 -CITY NO. 16-A SUPPLY WELL GROUT ABANDONMENT
If the well screens cannot be extracted from the well, the well will be decommissioned and
properly abandoned using perforate and pressure-grouting techniques by the selected
Contractor. The Hydrogeologist will develop the Contractor's scope of work and cost
estimates for the City, design the abandonment process, obtain the regulatory permissions to
abandon the- well, assist the City in scheduling, overseeing and directing the work on site,
arrange for building and site protection, review/reconcile the Contractor's invoices to the City,
provide two camera surveys of the well if needed, develop and file the appropriate final
documentation for the regulatory process and the City's files, and provide regular project
updates to the City.
Estimated consulting costs for Task No. 1.6 is $ 7,700.

a municipal water supply well by the selected contractor. The Hydrogeologist will:
• design the well reconstruction
• develop the technical specifications
• develop the Contractor's scope of work and cost estimates for the City
• develop a bid schedule and assist the City with the review of bids from contractors
Once the contract is awarded the Hydrogeologist will attend apre-construction conference,
and assist the City in scheduling, overseeing and directing the reconstruction work on site.
Hydrogeologist will also assist the City in arranging for building and site protection,
review/reconcile the Contractor's invoices to the City, and provide two camera surveys of the
well if needed. Hydrogeologist will:
• design and oversee the development of the well
• design and conduct hydraulic testing of the reconstructed well
• obtain and deliver water-quality/water chemistry samples to the laboratory and follow
those analyses through the process
• develop and file the appropriate final documentation for the regulatory process and the
City's files, provide regular project updates to the City
• create an as-built "Composite Diagram" of the reconstructed well for the City's well
database
• develop a final comprehensive report to the City
Laboratory analytical fees for a full suite of New Source Monitoring and geochemical
interpretation/modeling are also included in the Hydrogeologist's cost estimate.
Estimated consulting costs for Task No. 1.7 is $ 32,000.
