Our participation in the design and construction of the PFAS treatment facility at Champ Landfill, A Waste Connections Company in St. Louis, MO, was a significant milestone for our client. This project presented us with the challenge of addressing environmental concerns and regulatory requirements related to PFAS contamination in the landfill’s wastewater.
We approached this challenge with careful planning, coordination with government agencies for permits, and effective construction management to ensure the successful completion of the project. Our team worked diligently to design and construct a treatment facility that met all regulatory requirements and used advanced proprietary equipment to effectively remove PFAS from the leachate.
The treatment process involves intercepting leachate wastewater at an average flow rate of 73 gallons per minute, with peak flow rates of up to 90 gallons per minute. After removal of the PFAS, the wastewater discharges back to the original sanitary sewer system, where it continues to a wastewater treatment facility for final treatment. The process generates a thick foam collected into a separate tank, which collapses to liquid form before passing through activated carbon and Ion Exchange (IX) resin that captures the PFAS molecules. The process removes the PFAS from the wastewater, utilizing an estimated 150 cubic feet of activated carbon annually and 1,000 cubic feet of ion exchange resin. The active carbon and IX resin are changed once their ability to capture PFAS reaches capacity.
SCS’s contributions to the design and construction of this facility highlight our part in the application of advanced technology and newly developed processes implemented in the PFAS treatment facility at Champ Landfill, showcasing our commitment to utilizing the best available tools and technology for environmental protection and regulatory compliance.
The outcomes of this project were highly successful. The new wastewater treatment facility was completed within the specified timeframe and budget, providing ECT2 with a solution to manage PFAS contamination at Champ Landfill. This solution contributed to environmental protection, ensured current and future regulatory compliance, and improved waste management practices at the site.
Overall, our participation in this project demonstrates SCS Engineers’ role in applying advanced technology and efficient processes to handle complex construction projects and deliver comprehensive solutions to our clients. The successful collaboration between SCS and ECT2 showcased the expertise and capabilities of both parties, further solidifying our reputation as a trusted partner in environmental construction projects.
