III. DESCRIPTION
A. Background
The City has recognized that the steel casing used in wells prior to 2002 is prone to
corrosion and associated water quality problems. The City is taking a preventative
approach to steel casing wells and evaluating their condition if they are older than
10 years. Evaluation can result in lower costs of reconstruction and improved water
quality. Since 2002, eight of the City's wells have been constructed with PVC
casing to eliminate the problems due to con•oding steel casings.
The City is also working system wide to improve water quality as it pertains to iron
and manganese levels. Although not a regulated contaminant, high iron and
manganese levels typically lead to an undesirable brown coloration of water and a
metallic taste. The iron and manganese particles also accumulate in water mains
requiring the Water Division to conduct frequent flushing to remove the
sedimentation.
B. Proposed Project
This project is for the evaluation of the Well #15 casing, which was constmcted
with steel casing 19 years ago. Well #15 has many of the same characteristics as
Well #17 which had to be reconstructed after 9 years. Tasks are included in the
project scope to reconstruct Well #15 if the evaluation shows that a reconstruction
is warranted. Well #15 is also a source of iron and manganese in the water
distribution system and water chemistry will be evaluated as part of the project to
help the City identify possible treatment methods for reducing iron and manganese.
N. IMPACT
A. Strategic Impact:
This project meets our mission requirements to indentify and prioritize work to
anticipate, plan and provide public services and facilities that support the needs of
our growing community and ensure modern reliable facilities while maintaining
financial stewardship.
This project is in line with our preventative approach of evaluating steel casing
wells at ten year intervals. These evaluations allow for the early diagnosis of
corroded casings which in tum alleviate service interruptions and reduction in
capacity.
This project also meets our mission to enhance and protect the quality of our water
supply. By evaluating the chemistry of Well #15, we are taking the first step to
identifying possible improvements to the Well which could lower iron and
manganese levels in the distribution system.

TASK ORDER NO. 0707a
Pursuant to the
MASTER AGREEMENT FOR PROFESSIONAL SERVICES
BETWEEN
CITY OF MERIDIAN (OWNER) AND HYDRO LOGIC, INC (HYDROGEOLOGIST)
This Task Order is made this th day of NOVEMBER, 2012 and entered into by and
between the City of Meridian, a municipal corporation organized under the laws of the State of
Idaho, hereinafter referred to as "City", and accepted by (HYDRO LOGIC, INC), hereinafter
referred to as "HYDROGEOLOGIST" pursuant to the mutual promises, covenant and
conditions contained in the Master Agreement (Category 6A) which includes the attached Rate
Schedule, between the above mentioned parties dated December 6, 2011. The Project Name
for this Task Order 0707a is as follows:
CITY OF MERIDIAN
MUNICIPAL WATER SUPPLY WELL NO 15 RE-
EVALUATION OF CURRENT CONDITION OF WELL
CONSTRUCTION, GROUNDWATER CHEMISTRY, AND
RECONSTRUCTION DESIGN
PROJECT UNDERSTANDING
The City of Meridian municipal supply Well #15 was constructed in May of 1993. This steel-
cased well is now 19 years old. The City believes the well may be very near the end of its
useful life (with the original construction) such that it needs to be evaluated for reconstruction
or replacement.
It is considered highly likely that the City will have to re-construct or replace Well #15 because
of its corroded casing and against corrosive break through (holes) that could allow sand
production or even catastrophic collapse. However, the existing well remains useful in that it
can be used as a tool to ascertain much about the ground water geochemistry at the site to
provide valuable information for a re-constructed well or for a replacement well should that
become necessary. This Task Order is aimed at the multiple scopes of work needed to
achieve a secure, long-term, and high-quality water supply source for the City at this site.

Included in the costs for this task are the laboratory, analytical fees and two sets of field
instruments with calibration standards for 12 sampling events for field-measured parameters
estimated at approximately $ 3,000 and review df contractor's invoices and recommend action
for payment.
TASK 1.4 -CITY WATER WELL NO. 15 HYDROGEOLOGIC ANALYSIS AND REPORT
If warranted, and pre approved by the City, Hydrogeologist shall develop ancillary data into a
comprehensive scientific report and present it to the City. Hydrogeologist shall conduct a legal
review of the developed report.
TASK 1.5 -CITY WATER WELL NO. 15 RECONSTRUCTION DESIGN
Underground evaluation of water wells is most often conducted in a "discovery" environment"
whereby situations often arise that are unexpected and which must be dealt with at the time of
discovery. If any of the previous Tasks identify problems with the well that need attention,
Hydrogeologist will:
• consult with the City's Project Manager to determine the best course of action to repair,
perform maintenance, or modify the well,
• develop plans and specifications as appropriate to solicit contractor bids/quotes for the
work,
• If requested, assist the City in obtaining bids/quotes for the work according to City
policy,
• observe and inspect the reconstruction work,
• update or recreate as-built drawings at the conclusion of the reconstruction work
including any requested reports.
Hydrogeologist will perform field surveys for evaluation and reconstruction and will serve as
the City's liaison between the contractors and develop technical specifications for contractual
agreements for the work.
Hydrogeologist will inspect all tools to be inserted in the well prior to insertion.
Hydrogeologist will ensure, to the best of its ability, that all instruments, tools, cables, water
tanks,. hoses, and equipment used in the well are disinfected and cleaned by the Contractors
working on the well (including heating of pipe and pumps that cannot be properly disinfected
by other means).
Hydrogeologist will develop any necessary change orders, for Project Managers approval, to
the work and keep the City Project Manager regularly updated with respect to the work.

Hydrogeologist will also review contractor invoices and make recommendations for payment.
TIME OF COMPLETION and COMPENSATION SCHEDULE
Hydro Logic, Inc. shall commence this work on the day after City approval.
Task 1.1 of this order will require approximately one week.
Onsite field portions of the evaluation work will require a maximum of four-to-five weeks
to complete depending upon contractor availability.
• Ground water chemistry results, excluding radionuclides (not expected to be an issue
here) will be ready in approximately four weeks.
Utilizing the modeling and interpretation of the geochemistry data, an interim technical
memorandum with recommendations from the evaluation shall be completed within 75
days from Notice-To-Proceed. There will be some overlap between the evaluation and
the proposed geochemistry experiments. Hydrogeologist estimates that the three
sampling intervals, including pump removalslinstalls, sampling, analytical processing,
data interpretation and final report may take an additional 13 weeks. However, with an
estimated four week overlap of laboratory processing, the experimentation phase with
report is estimated to require an additional (to the evaluation's five weeks) 9 weeks to
complete. Therefore, not allowing for the approaching holidays, we need approximately
14 weeks to do the job. So, with consideration of the holidays and the time for the City
to process the Task Order, it is reasonable to think the Tasks 1.1-through-1.3 could be
completed by the end of January 2013.
The following schedule is based on a Notice to Proceed (NTP) from the City by November
2012 and resulting in Final Design being completed by April 2013. A NTP issued on a different
date will change the schedule accordingly.
