Assessment Report was completed this month identifying that two of the four UFA wells are
operating at significantly reduced capacity and a third has not been operational since
construction due to high sand content. This preliminary design will develop the rehabilitation
plan to be executed in FY20-2I to restore the wells to as near to design capacity as possible. The

Agenda Item #6.
Proposal to Provide Professional Engineering Services for
Upper Floridan Aquifer Well Rehabilitation Preliminary Design
Services to be provided by: Mock■Roos
Services provided to (Client): Village of Tequesta
Proposal Date: July 28, 2020
Proposal Terms
A. Project Description:
The Village of Tequesta has a water use permit (No. 50-00046-W) from the South Florida Water
Management District (SFWM D) that allows the withdrawal of 401 million gallons (MG) per year from
the surficial aquifer and 1,251 MG from the brackish Upper Floridan Aquifer (UFA). The Village
currently runs three (3) production wells tapping the Upper- Floridan Aquifer. A fotlrth well (R4) has not
been significantly operated more than the minimum required for testing because of suspended solids
production. Only having three wells in production means that all three wells need to operate most of the
time to pump the annual allocation that makes up 76 percent of the Village's water supply.
Mock*Roos and Connect Consulting, Inc. (CCI) recently completed the Village of Tequesta Wellfield
Condition Assessment Report earlier this year and found that UFAWell R2 has lost approximately 60%
specific capacity since construction and needs rehabilitation to restore performance. UFA Well R3
currently has a low pumping level and the pump is not operating as designed. "There is no historical
performance data oil this well; however, based oil the low specific capacity it has also likely lost capacity.
Upper Floridan Aquifer production Well R4, which has reportedly been out of service due to the
production of suspended solids, is an essential well for the Village's wellfield. Because the well has been
out of service, the other three in-service wells have been pumped more than planned to make up for its
loss. The result has been loss of capacity (R2 known and R3 likely) and the degradation of raw water
quality from additional use.
At the Village's request, Mock■ Roos and CCI will perform the services as outlined in B. Scope of
Services below:
B. Scope of Services:
1. Attend kick-off meeting with Village staff. Obtain available project specific record drawings and
data From the Village, Florida Department of Transportation, and South Florida Water
Management District.
2. Review available records and develop a conceptual overview of the rehabilitation approach for
UFA Well R2 and R3 which is anticipated to include type and volume of acid to be used, an
estimated volume of water that will be generated, exhibit(s) showing the conceptual route where

Agenda Item N.
water may be discharged/disposed of during the development process, initial contact with
permitting agency(s), list of anticipated permits), and conceptual estimate of the rehabilitation
cost. It is anticipated that the formation fluids water for R2 and R3 will be discharged/disposed of
through an existing easement and into the US-1 drainage system.
3. Review available well construction and hydrogeologic data for UFA Well R4 and prepare
conceptual recommendations for steps to be taken to rehabilitate the well and dispose of
development water with the end goal of bringing the well online thus providing essential
additional capacity to the Village's UAF wellfield.
4. The findings will be coordinated with the Village during the preliminary design and a brief draft
technical memorandum will be developed to summarize the findings, exhibits, and engineer's
opinion of probable construction cost. The opinion of cost will be in a format that can be used to
develop a phasing plan to proceed with implementing the project. Attend one review meeting
with Village staff to discuss the draft technical memorandum, incorporate minor change and
provide final technical memorandLIM.
Assumptions:
.�.
1. Village staff will provide access to the UFA wells as needed.
2. Village to provide current GIS database and available records for UFA R4.
3. Project deliverables will be emailed PDF files of the draft and final technical memorandum (3
bound copies of the final report will be provided to the Village upon request).
D. Additional Services:
1. Any services not included in the Scope of Services will be considered Additional Services.
2. Additional Services can be provided upon Mock■Roos receiving signed authorization from
Client.
3. Additional Services resulting from the following can be provided without Client's authorization:
1) legal and/or regulatory requirements or changes, 2) delays or price increase not in Mock•Roos
control, 3) emergencies or acts of God, 4) threatened or endangered species, 5) hazardOLIS
conditions, 6} or any services required to protect the health, safety, and/or welfare of the public.
