HomeMy WebLinkAbout06.b.02.b SA No. 2 Kimley Horn Corrosivity Water Sampling EXECUTIVE SUMMARY
AGENDA ITEM:
Proposed Supplemental Agreement No. 2 to the Hydrogeological and Environmental Professional
Engineering Services RFQ Agreement 2022/2023-A02 with Kimley-Horn and Associates, Inc.
(Kimley-Horn)for the Saratoga Springs Water Treatment Plant(WTP) Corrosivity Water Sampling
Date: December 14, 2023
BACKGROUND:
The Florida Department of Environmental Protection requires new Public Water Systems to
conduct initial lead and copper tap sampling or complete a corrosivity study showing the new
source (i.e., wells) will not increase the corrosivity of the current water supply. CCUA staff will
be required to conduct this sampling or study at Saratoga Springs WTP once we begin providing
water to customers.
Kimley-Horn conducted a corrosivity study for CCUA when Peters Creek WTP was tied into the
Lake Asbury Grid Public Water System. The completion of the study allowed CCUA to forgo
multiple lead and copper tap sampling events, saving money in laboratory costs and Water
Operator staff hours. CCUA has asked Kimley-Horn to conduct the corrosivity study for Saratoga
Springs WTP to eliminate the need once again for the initial lead and copper tap monitoring that
would otherwise be required. Staff considers the Kimley-Horn scope of services and fee to be
reasonable.
BUDGET:
Operations did not budget for this item. Staff plans to use funding from the Environmental
Compliance Department's Subcontractors budget for this project.
RECOMMENDATION:
Staff respectfully requests the Board of Supervisors approve Supplemental Agreement No. 2 with
Kimley-Horn and Associates, Inc., in the amount of $1,000 for the Saratoga Springs Water
Treatment Plant(WTP) Corrosivity Water Sampling

Saratoga Springs Corrosivity Water Sampling
Clay County Utility Authority (CCUA) is planning to connect the Saratoga Springs Treatment Plant (WTP)
to its Lake Asbury Grid.As such,the Florida Department of Environmental Protection (FDEP) is requesting
that CCUA conduct water quality sampling to demonstrate that the addition of the water from Saratoga
Springs WTP will not affect the corrosivity of the water within the Lake Asbury Grid. Kimley-Horn and
Associates, Inc. (Kimley-Horn) will conduct water quality sampling at three locations to evaluate
corrosivity. Additionally, Kimley-Horn will prepare and submit a letter report to the FDEP documenting
the corrosion analysis.
Scope of Services
The following scope of services is for Phase 1 and 2.
Phase 1 Water Quality Sampling
This task primarily consists of the collection of up to three water quality samples from the Saratoga Springs
WTP, and the Lake Asbury Grid. Laboratory analysis will be performed by Advanced Environmental
Laboratories, Inc. (AEL). AEL will direct bill CCUA for the analytical analyses. This task will consist of the
following:
A. Coordinate with CCUA staff to collect the three water quality samples.
B. Coordinate with AEL to analyze the samples for lead, copper, pH, and corrosivity.
C. The following field parameters will be measured and recorded during sampling:temperature, pH,
specific conductance, dissolved oxygen, oxidation/reduction potential, and turbidity.
D. The water quality samples will be collected in laboratory provided and preserved containers.
E. Sampling will be performed in general accordance with FDEP Standard Operating Procedures.
F. Deliver samples to AEL for analysis under chain-of-custody protocol.
Phase 2 Letter Report
Kimley-Horn will prepare a letter report upon receipt of the laboratory results. The letter report will
include the following:
A. Concise summary of the sampling methodology and results.
B. Tabular summary of the laboratory data.
C. Discussion and interpretation of the analytical data.
D. Conclusions and recommendations based on the analytical results.
E. Copies of the field sampling logs.
F. Copies of the laboratory data sheets.
Kimley-Horn will provide CCUA with a draft copy of the letter report to review prior to submittal to the
FDEP. The final letter report will be signed and sealed by a Professional Geologist (P.G.) licensed in the
State of Florida. The final report will be submitted in electronic (PDF) format, unless requested by CCUA
or the FDEP to furnish hard copies.
