Funnel & Gate System, Purdue Ect Team

ECT Fact Sheets

The limited success and high cost of traditional 'active' ground-water-contaminant plume management efforts (i.e., pump-and-treat systems) has stimulated a search for less expensive 'passive' plume interception and in-situ treatment technologies. The 'funnel and gate system,' which uses heterogeneous (surface-mediated) reactions on porous media to degrade dissolved contaminants, is one passive technology under consideration.
