PFAS Products

In-Situ Remediation Model (ISR-MT3DMS)

Porewater Solutions has developed a unique PFAS reactive transport model (ISR-MT3DMS) capable of simulating the performance of in-situ colloidal activated carbon barriers. We are currently using ISR-MT3DMS to provide modeling support on multiple SERDP-ESTCP projects for the U.S. Department of Defense.

Visual CHEM

Porewater Solutions has developed an innovative PFAS visualization and database tool (Visual CHEM) which uses radial diagrams to provide a powerful forensic assessment tool. Radial diagram maps provide a wealth of information for evaluating spatial and temporal trends for a wide range of PFAS. Unique redox radial diagrams facilitate the identification of areas that are favorable for precursor transformation to PFAS of Concern.
