Illinois Tech assistant professor awarded funding to stop spread of ‘forever chemicals’ into waterways
January 26th, 2023
Illinois Institute of Technology (Illinois Tech) assistant professor David Lampert was recently awarded funding by the U.S. Environmental Protection Agency’s People, Prosperity, and the Planet (P3) Student Design Competition for a project to stop the spread of “forever chemicals” into waterways. Lampert’s project—one of just three nationwide selected for phase II funding—focuses on preventing the movement of perfluoroalkyl and polyfluoroalkyl substances (PFAS) […]
Differentiating sources of PFAS with multiple lines of evidence
January 24th, 2023
Per- and polyfluoroalkyl substances (PFAS) are ubiquitous in the environment. Because a multitude of common commercial products contain PFAS, the potential exists for PFAS contamination to impact a wide variety of business sectors and practices. It’s especially difficult to determine who’s responsible for addressing PFAS when contamination likely stems from several origins. Due to the proliferation […]
EPA issues next test order under national testing strategy for PFAS used in plastics, chemical manufacturing
January 10th, 2023
The U.S. Environmental Protection Agency (EPA) has issued the next Toxic Substances Control Act (TSCA) test order requiring testing on per- and polyfluoroalkyl substances (PFAS) under EPA’s the National PFAS Testing Strategy. This action orders companies to conduct and submit testing on trifluoro (trifluoromethyl) oxirane (HFPO), a perfluoroalkyl substance used in making plastics. This is […]

Geosynthetics for CCR, PFAS and energy applications
October 1st, 2021
This issue of Geosynthetics magazine delves deep into two innovative uses of geosynthetic clay liners (GCLs) in very different applications: coal combustion residual (CCR) leachates and per- and polyfluoroalkyl substances (PFAS) mitigation in landfills. We also examine three case studies of energy companies using high-density polyethylene (HDPE) geomembranes for flowback water in water evaporation/recycling ponds. […]
Hybrid geosynthetic clay liners for attenuation of PFAS in landfill leachates
October 1st, 2021
An exponential increase in understanding of the provenance, migration, and fate of per- and polyfluoroalkyl substances (PFAS) is evident over the past decade. The environmental and health concerns from this group of contaminants are well recognized, but they are still evolving with advancing studies. A key property of PFAS compounds at a molecular level is […]

Seaming dissimilar geomembranes Q: I kindly request your technical support in the questions below: A nonpolyethylene geomembrane was used in phase 1 of the tailings dam waterproofing system of a gold mine. For the expansion (phase 2), the use of a high-density polyethylene (HDPE) geomembrane is being evaluated. How can the HDPE geomembrane join the bituminous […]
CETCO launches FLUORO-SORB adsorbent for the remediation of PFAS
June 3rd, 2019
Amid a deeper awareness of the health and environmental impact of per- and polyfluoroalkyl substances (PFAS), CETCO is pleased to announce the launch of FLUORO-SORB® adsorbent, a proprietary, NSF-certified product that effectively treats multiple variants of PFAS. Unlike other sorbent products that are selective and unpredictable in adsorbing PFAS, FLUORO-SORB adsorbent binds the entire spectrum […]

Geomembranes for canal lining Q: Our company is an international member of the Industrial Fabrics Association International (IFAI). Our government is planning to line their water canals with a geomembrane to prevent water seepage into the soil. We have been approached by many to suggest the most suitable material with specifications to guide them in […]
