SUBJECT
recommendation
Authorize an engineering services agreement for the development of the Per- and Polyfluoroalkyl Substances (PFAS) Management Roadmap.
end
PURPOSE
This Roadmap is designed to be a holistic approach for assessment of North Texas Municipal Water District’s water, wastewater, and solid waste systems in relation to management of PFAS within these systems. The outcome of the Roadmap is a process collaborated across all NTMWD systems that the District can use to guide its decisions and investments related to PFAS management and compliance with currently proposed regulations within the next 5-10 years.
RECOMMENDATION
The Executive Director and NTMWD staff recommend the Board of Directors authorize the Executive Director to execute an engineering services agreement (ESA) as follows:

BACKGROUND
• The Environmental Protection Agency (EPA) classifies PFAS as an public health and environmental issue facing communities across the United States. PFAS have been manufactured and used in a variety of industries in the United States and around the globe since the 1940’s, and they are still being used today. PFAS can be found in surface water, groundwater, soil, and air - from remote rural areas to densely-populated urban centers. A growing body of scientific evidence shows that exposure at certain levels to specific PFAS can adversely impact human health and other living things.
• NTMWD requires tools, validated methods, and an overall approach in the management of PFAS to demonstrate facility compliance to changing federal requirements. Limiting exposure and addressing PFAS hazards is a priority at District treatment and disposal facilities.
• This Roadmap would assess NTMWD water, wastewater, and solid waste facilities for efficiency of PFAS treatments, and provide recommendations to increase efficiency and continue to meet federal requirements. All departments of NTMWD would utilize the resulting process to appropriately invest and prioritize construction efforts in the future.
PROJECT COMPONENTS
• Review existing state of PFAS regulations and occurrence, transport pathways, and management at NTMWD. Obtain, review and analyze relevant information, data, reports, master plans, studies from NTMWD related to PFAS management including sampling data collected from water, wastewater and/or solid waste systems, industrial pre-treatment surveys, sources evaluations, treatment evaluations, or other relevant studies or reports.
• Identify and summarize the potential sources and transport pathways of PFAS within the NTWMD systems, including point and non-point sources, and transport pathways between the water, wastewater and solid waste systems.
• Screening evaluation of treatment and management options. The screening evaluation will be used to eliminate “fatal flaw” or otherwise undesirable or impractical treatment or management options within each system. The evaluation will provide high-level, qualitative assessment of key issues and, where applicable, high-level, relative costs.
• Prepare PFAS management roadmap. Based on information developed and input received from previous tasks, develop a plan for management of PFAS for NTMWD water, wastewater and solid waste facilities.
