The University intends to conduct research for the Florida Department of Environmental Protection (FDEP) on the remediation of per and polyfluoroalkyl substance (PFAS) contaminated soils using thermal treatment technologies (Project). PFAS are a large group of chemicals used in a variety of industrial and consumer applications that have known toxicity to human health. Over 100 PFAS-contaminated sites have

been identified in Florida with many sites, including firefighting training facilities, military installations, and dry cleaners, anticipating the need for future soil remediation. Preliminary research has indicated high temperature thermal treatment to have promise in the remediation of PFAS. However, at the pilot-scale existing research is limited, with insufficient understanding of the transformation and/or degradation of PFAS in effluent gases during treatment. This project aims to address these knowledge gaps by assessing the destruction feasibility of PFAS in contaminated soils using a multi-phase sampling and analysis approach determined by the University. 1.2 Scope of Work The University will select a vendor to thermally process approximately 200 tons of PFAS-impacted soil over a five-day period. The following scope of work is suited to traditional, ex-situ desorption- oxidation technologies; however, other vendors possessing other ex-situ thermal technologies are encouraged to respond – providing that the alternative technology demonstrates comparable target temperatures, can accommodate the University’s sampling efforts, and execute the proposed work in a similar duration. At this time, the exact test site and soil source is being determined by the University; however, both are anticipated to occur within Florida. It is therefore recommended that potential vendors configure their proposals to be scalable where appropriate (e.g., mobilization or transport per distance). The selected vendor will be provided with approximately 200 tons of excavated soil in the form of lined and covered roll-off containers (i.e., eight 20 cy containers or comparable vessels) situated on, at minimum, 100,000 sf of relatively flat, accessible land. If the selected vendor is a mobile facility, the vendor will mobilize to the determined location within one-hundred and one (101) days from the issuance of notice to proceed (see Section 1.4). If the selected vendor is a stationary vendor, the vendor will be responsible for transporting the filled roll-off containers to their location of operation within the same period described previously. Through the Project duration, appropriate BMPs will be applied by the vendor to control erosion and sediment to minimize pollution to the surrounding environment. The selected vendor will be responsible for ensuring the Project soils remain covered and protected during the mobilization and testing duration. Prior to the five-day testing period, the vendor will conduct or outsource preliminary soil characterization to ensure facilities are tuned for the specific soil (i.e., moisture content, organic matter). Following the completion of mobilization and prior to the five-day testing period, the vendor will ensure facility equipment is in working condition. Any immediate, necessary maintenance or equipment replacement will occur prior to testing and is solely the responsibility of the vendor. Testing will be conducted over a five-day experimental period (see Table 1). Over this testing period, the vendor will adhere to the following operational schedule at a variable operational tonnage of three to five tons per hour. All processed soil will be homogenized by the vendor prior to operation. Table 1.
