STAFF REPORT
AGENDA ITEM: Professional Engineering Services -Assessment of the Buccaneer Floridan
Aquifer Production Wells
SUBMITTED BY: Donna Kaluzniak, Utility Director
DATE: August 3, 2001
BACKGROUND: The City is in the process of renewing the potable water Consumptive Use
Permit for the Atlantic Beach and Buccaneer districts through the St. Johns River Water.
Management District (SJRWMD). During apre-application. meeting, the SJRWMD noted that
the City would be required to perform geophysical and video logging of our eight wells as part of
the permitting process. This process includes pulling the well pumps, inspecting and televising the
wells, and measuring various parameters to determine the integrity of the well casings and sanitary
seals, checking for voids in the open hole section of the wells, and determining their overall
condition.
In addition, one of the wells at Water Plant #3 (902 Assisi Lane) has been steadfly losing
production capability. Performing the logging and inspection activities noted above would allow
us to determine the exact cause of the problem, and make needed repairs before reaching a critical
stage.
Camp, Dresser & McKee (CDM) is assisting the City in the permitting process and staffrequested
a proposal to perform the above work and provide an analysis and recommendations based on
their findings for the four wells in the Buccaneer District. Wells in the Atlantic Beach District will
be logged and inspected during the lower demand period in the fall.
CDM has submitted a proposal to perform the above work in the amount of $39,597. They will
use W. Earl Floyd & Son, the contractor who has performed the majority of our well installation
and repair work, to pull the wells and conduct the video and geophysical logging. CDM will
provide a professional geologist to be on-site during this work, to observe and review the findings
and make recommendations for well repairs, rehabilitation or replacement. CDM will provide
drawings for any modifications recommended or made during the project. The expected time to
complete this work is 2 - 3 days per well.
If the findings show that immediate repairs or modifications are needed, staff would like to
perform this work immediately, while the wells are already off-line and the pumps pulled, if
possible. For this work, the City would contract directly with W. Earl Floyd & Son, at a rate of
$85.00 per hour, plus materials.
In order to determine if the actual cost of the logging and hourly repair rates were reasonable,
staff requested quotes on these items from two other well contractors. W. Eazl Floyd & Son's
logging rates were mid-range, and their hourly repair rates were less than half of the other well

drillers' costs. Because staff has been very pleased with the quality of work and expertise
provided by W. Earl Floyd & Son, and expects there will be some repair work required, we
recommend using this firm, as proposed by Camp, Dresser & McKee.
BUDGET: A total of $100,000 is available in the Water Utility Fund, under account number
400-4101-533-6300. This amount was originally budgeted for the Church Road Water Main, for
which we received CDBG funds.
RECOMMENDATION: Award the' contract for Assessment of the Buccaneer Floridan
Aquifer Production Wells to Camp, Dresser & McKee in the amount of $39,597, and authorize.
the City Manager to sign the contract. Authorize staff to proceed with necessary repairs, with a
follow up report on the activities and costs as soon as they are available.

the parties. ENGINEER shall provide Basic and Additional Services as set forth below.
PART 1 -BASIC SERVICES
CDM Project No.:
Title of Project: Assessment and Maintenance of the Buccaneer Floridan Aquifer
Production Wells
1.0 DESCRIPTION OF TASK ORDER
The work effort to be completed by CDM for Task Order No. 2000- consists of the
resident oversight of contractors involved in removing the pumps from four Floridan
aquifer production wells located at the Buccaneer Water Treatment Plant. The pumps will
be inspected for build up of minerals (calcification) and general maintenance, repair and
evaluation. Following the removal of the pump from the well, the well will be logged with
video and geophysics to evaluate the condition of the well.
2.0 SCOPE OF SERVICES
TASK 1 Project Planni ~ and Scope Development
CDM will develop a scope of services for the evaluation of the Buccaneer Floridan aquifer
production wells. CDM will work with the City of Atlantic Beach and their contracted
Well Driller on scope, costs and scheduling.
TASK 2 Review Existing Data
This task consists of reviewing data on existing Buccaneer Floridan aquifer production
wells including location, casing diameter, depth of casing(s), total depth of the well, date
of installation, yield, size of existing pump, and water quality data.

TASK 3 Resident Project Representation
For this task CDM will place professional geologist in the field while the pumps aze pulled
from the wells. The geologist will work with the well driller in determining the need for
maintenance or repair of the pumps. The geologist will also review the findings of the
geophysical and video logging in determining the condition of the well and the possible
need for well rehabilitation, as needed. It is estimated that it will take two to three days to
complete this work for each well. CDM will subcontract with the city's well driller for all
downhole services including pulling the pumps, geophysical logging, and video logging of
the wells.
Any maintenance or repairs to be performed by the well driller will be approved by the
City prior to completing the work. Any costs for pump or well repairs/rehabilitation will
be billed directly to the city at the well drillers hourly rate. After completion of the field
work, CDM will send a letter to the city describing the work performed along with a
summary of the conditions of the wells. This,letter can then be sent to the SJRWMD in
support ofthe CUP application.
2.0 ASSISTANCE OR DATA TO BE PROVIDED BY THE CITY
The city will provide to CDM the results of any recent well maintenance records or well
logging performed on the wells in BuccaneerService Area. These data will help CDM
evaluate any trends in welUpump performance over time particulazly between maintenance
events.
3.0 TIME OF COMPLETION
It is estimated that it will take between two to three days to perform the inspection,
testing, and maintenance on each well. The work described above will be completed
within 60 days of receipt of the City's written Notice to Proceed.
4.0 COMPENSATION AND PAYMENTS
The method of calculating fees is established in Attachment C for the estimated level of
effort presented in Attachment A. The lump sum fee for Tasks 1 to 3 inclusive, based
