Porewater Solutions has developed an innovative PFAS visualization (Visual PFAS) 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.

Radial diagrams may be useful for visualizing trends for organic and inorganic chemicals, particularly when evaluating the efficacy of natural or enhanced biodegradation processes.  Modified radial diagrams are particularly useful for assessing the zonation of redox conditions in groundwater, and have been demonstrated by Carey et al. (1996, 1999, and 2003). 

Visual PFAS is a simple software tool to facilitate the plotting of radial diagrams for environmental applications.  Click the link below to download:
