Visual PFAS

Porewater Solutions has developed Visual PFAS™, an innovative software tool that allows you to create radial diagram and stacked bar maps in only minutes. Visual PFAS™ will help to improve both your conceptual site model, and your ability to communicate PFAS trend analyses with others. Visual PFAS™ is applied in support of site characterization, remediation performance evaluations, and forensic assessments.

U.S. Patent Pending – PFAS Water Treatment

Porewater Solutions has filed a U.S. patent claim related to a specialized water treatment process that will enhance PFAS treatment in granular activated carbon (GAC) systems. This patent applies to both large treatment plants and point-of-use systems.
