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 […]
