SOUTHEAST LANDFILL LEACHATE TREATABILITY STUDY
CITY PROJECT NO.: 104942
The scope set forth herein defines the work to be performed by the ENGINEER in
completing the project. Both the CITY and ENGINEER have attempted to clearly define the
work to be performed and address the needs of the Project.
PROJECT DEFINITION AND BACKGROUND
In response to the United States Environmental Protection Agency proposed maximum
contaminant levels for PFAS compounds in drinking water, the CITY initiated a PFAS
management strategy focused on reduction through source identification and, if needed,
removal through treatment.
To support this, the CITY is evaluating options to proactively reduce sources of PFAS which
may be discharged to their existing wastewater collection and treatment facilities. PFAS is
not typically attenuated in most wastewater treatment processes, resulting in the effluent
being discharged to the environment and may adversely impact drinking water sources.
Like Publicly Owned Treatment Works, landfills do not actively produce PFAS and instead
are passive receivers given their role in managing society's wastes in a safe and responsible
manner. As a result, landfill leachate often contains significant levels of PFAS, which has
been identified as a specific contributor of PFAS to the Publicly Owned Treatment Works.
This resulted in the CITY implementing a moratorium on acceptance of trucked leachate at
the Village Creek Water Reclamation Facility (VCWRF). However, the CITY is still accepting
direct discharge of leachate from their Southeast Landfill (SEL) to VCWRF, which
contributes a significant mass load to the plant influent. Management and/or removal of the
PFAS load to the VCWRF is important to reducing the potential for this constituent to be
released.
This scope of work defines the proposed approach to evaluate feasible technologies, define
implementation concepts, and develop a selected design for a leachate PFAS treatment
facility at the SEL with consideration for the potential implementation of a centralized facility
allowing for acceptance, storage and treatment of leachate from other regional municipal
solids waste landfills.
WORK TO BE PERFORMED
This Amendment No. 3 Southeast Landfill Leachate Treatability Study (Project) will be
executed independent of, but concurrent to the on-going EMERGING CONTAMINANTS

2.1. Data Collection and Review
ENGINEER will submit a formal data request to the CITY inclusive of the following,
respective to each of the six candidate landfills:
Historical leachate quality/characterization data (up to 5-years) inclusive of
available PFAS analytical data, leachate quality testing (including data from
different source areas, e.g., cells or sumps, that may allow for source
segregation) and regulatory monitoring reports, and leachate production
volumes for landfills of interest.
SEL facility drawings, including site layouts for leachate and condensate
management facilities identified and relevant design data to facilitate
evaluation of PFAS treatment process implementation alternatives (Task 3).
Description of each landfill including total acreage and volumetric capacity
(total, active, closed) and general type(s) of solid wastes received since
inception
ENGINEER will review background information received from the CITY including:
Leachate and condensate process/facility layout drawings
Historical leachate and wastewater data to develop statistical data summaries
in table and graphical format relative to each landfill and VCWRF.
Pertinent studies/evaluations primarily focused on facilities condition,
improvement priorities, known future modifications such as landfill
expansions, and other leachate quality enhancement objectives such as
segregation of high concentration source areas.
ENGINEER will develop a Sampling and Analysis Plan to recommend additional
leachate analyses to address data gaps to support the project. The list would be
anticipated to include PFAS, as well as major anions, cations, select metals not
already analyzed as well as silica, strontium, orthophosphate, total dissolved solids,
conductivity, ammonia, total Kjeldahl nitrogen, nitrate/nitrite, biochemical oxygen
demand, chemical oxygen demand, pH, and oxidation reduction potential. For
rationale, if reverse osmosis is a candidate treatment technology, analysis of major
cations, anions, and certain other compounds such as barium and silica can be
helpful in evaluating their long-term effectiveness because membranes are subject to
both biological and inorganic fouling. Similarly, ion exchange resins targeted towards
PFAS removal are impacted by competing ions. This information is also useful for
electrochemical oxidation.
Following receipt of all sampling results, ENGINEER will compile all data and analyze
for trends and other information that may be crucial for consideration in assessing
treatment technologies.
Workshop No. 1: ENGINEER will conduct a workshop with the CITY to review the
outcome of data review, data gaps and additional sampling that may be needed to
advance the project. Meeting is assumed as 2-hour duration, exclusive of

TASK 3. Treatment Alternatives Assessment & Pilot Equipment Procurement Support.
This task includes a review of PFAS treatment alternatives for landfill leachate as identified
in the Preliminary Engineering Feasibility Report (PEFR) prepared by CITY, which identified
the following technologies:
Granular activated carbon
Foam fractionation
Electrochemical oxidation
Advanced oxidative processes
Ion exchange
The review will consider overall effectiveness both individually and in combination with other
technologies as well as both relative capital and operation and maintenance costs for the
alternatives investigated for either leachate alone or a combined stream of both leachate
and condensate. Potential treatment locations, system footprint, and staffing requirements
will also be considered. The ENGINEER will develop a summary table for comparing and
ranking the alternatives. Following evaluation of Treatment Alternatives, ENGINEER will
make recommendations as to which candidate technologies should be considered for further
evaluation. Recommendations for initial testing may consist of bench-scale treatability
testing by ENGINEER and/or technology providers. This well be used to screen
technologies for specific site applicability and identify up to two technologies for pilot scale
testing.
Following approval by CITY, ENGINEER will act as a agent of CITY in order to solicit
proposals from appropriate vendor/suppliers for field demonstration of treatment

technologies; it is assumed that each vendor will be responsible for a singular primary
component (e.g., foam fractionation), but testing may consider potential combination of
technologies in series.
3.1. Establish PFAS Treatment System Goals/Evaluation Criteria:
ENGINEER will work with CITY to establish performance criteria to be used in
evaluating the treatment strategy. These would be expected to include (but not
limited to):
Operating mode (batch, semi-batch, continuous)
Pretreatment requirements (including consideration for offsite receiving)
Ease of operations
PFAS residual material management (full destruction, offsite management,
sequestration, deep well injection)
Air emissions management
System redundancy and reliability
Scalability/phasing considerations
Constructability
Conceptual operating cost
Order-of-magnitude capital cost
3.2 Treatment Identification:
ENGINEER will review treatment technologies (assumed to be primarily technologies
previously identified in the PEFR by CITY, but ENGINEER will advise if an
alternative technologies should be considered in lieu of PEFR recommendation if
leachate quality suggest other options) and provide recommendations for the top
treatment approaches for consideration (assumed to be no more than 5 process
approaches). Alternatives may be stand-alone or combination of multiple unit
operations.
ENGINEER will establish the design basis for leachate (and condensate, if
determined to be included) characteristics. SEL leachate (and condensate) will be
used as the basis; available data from other regional landfills will be reviewed to
determine if adjustments to the SEL quality should be considered, or if received
material (if a regional treatment strategy is adopted) will be expected to meet the
SEL quality to be acceptable for receipt.
3.3 Treatment Analyses:
ENGINEER will compile information on each technology including performance
expectations and evaluate each against the performance goals.

Mayor and Council Communication
DATE: Tuesday, January 28, 2025 REFERENCE NO.: **M&C 25-0089
LOG NAME: 60PFASTREATMENTSTUDYA3-BROWN AND CALDWELL
SUBJECT:
(ALL) Authorize Execution of Amendment No. 3 to an Engineering Agreement with Brown and Caldwell in
the Amount of $654,588.00, for a Revised Contract Amount of $9,348,067.00, for the Emerging
Contaminants Per- and Polyfluoroalkyl Substances Treatment Study Project and Adopt Appropriation
Ordinance to Effect a Portion of Water's Contribution to Fiscal Years 2025-2029 Capital Improvement
Program
RECOMMENDATION:
It is recommended that the City Council:
1. Authorize execution ofAmendment No. 3 to City Secretary Contract Number 60733, an engineering
agreement with Brown and Caldwell, in the amount of $654,588.00, for a Revised Contract Amount
of $9,348,067.00 for the Emerging Contaminants Per- and Polyfluoroalkyl Substances Treatment
Study project; and
2. Adopt the attached appropriation ordinance increasing estimated receipts and appropriations in the
Water and Sewer Capital Projects Fund in the amount of $654,588.00, from available PayGo
residuals within the Water and Sewer Capital Projects Fund, for the purpose of funding the
Emerging Contaminants Per- and Polyfluoroalkyl Substances Treatment Study project (City Project
No. 104942) to effect a portion of Water's Contribution to the Fiscal Years 2025-2029 Capital
Improvement Program.
DISCUSSION:
The United States Environmental Protection Agency's (USEPA) ruling for regulating Maximum
Contaminant Levels and Hazard Index for Per- and Polyfluoroalkyl Substances (PFAS) in drinking water
has prompted the Water Department to formulate plans to monitor potential sources and reduce PFAS
levels through source identification and treatment (if necessary). Prior to the adoption of USEPA's final
rules, the Water Department initiated testing of multiple sources including raw water, sewer, and drinking
water to better understand the full water life-cycle challenge in removing these contaminants. Through
early testing, staff determined that additional advanced treatment may be needed at the drinking water
treatment plants in order to comply with the proposed PFAS regulations.
On December 12, 2023 Mayor & Council Communication (M&C 23-1075), the City Council authorized
execution of an engineering agreement with Brown and Caldwell in the amount of $1,304,303.00 to
conduct systematic sampling and testing of the water through various phases of the treatment process to
help determine the optimal treatment strategy for reliable and economical removal of PFAS. Sampling has
been conducted from all existing raw water sources and from various stages at all five City water
treatment plants. The results will affect all existing and future customers. On June 11, 2024 (M&C 24-
0513), the City Council authorized Amendment No. 1 to the engineering agreement in the amount
of $1,797,323.00, for additional engineering design services. On December 10, 2024 (M&C 24-1132), the
City Council authorized Amendment No. 2 to the engineering agreement in the amount of $5,591,853.00,
for additional engineering design services.
Amendment No. 3 will provide funding to identify treatment options and a final design for a treatment
system to remove PFAS from wastewater at the City-owned Fort Worth Southeast Landfill. Wastewater
from the facility was identified as a point source of wastewater containing PFAS and discharged into the
collection system. Anticipated benefits of this project include the reduction of PFAS in wastewater
treatment plant influent, effluent, and biosolids, as well as providing a demonstration facility that Fort
Worth can showcase to other industries, both local and regional, that have high levels of PFAS in their
wastewater as they evaluate PFAS reduction and removal options. Amendment 3 will provide for treatment
technology review, selection of the treatment technology, and design of a leachate treatment facility
capable of removal of PFAS.
It is the practice of the Water Department to appropriate its CIP plan throughout the Fiscal Year (FY),
instead of within the annual budget ordinance, as projects commence, additional funding needs are
identified, and to comply with bond covenants. The actions in the M&C will appropriate funds in support of
the Water's portion of the City of Fort Worth's Fiscal Years 2025-2029 Capital Improvement Program, as
follows:
