About the PFAS Mapping Tool

The PFAS Mapping Tool is a data-driven platform designed to visualize and analyze the global distribution and sorption behavior of per- and polyfluoroalkyl substances (PFAS) in soils and sediments. It combines curated datasets, machine learning predictions, and interactive geospatial mapping to support environmental scientists, regulators, and stakeholders in PFAS risk assessment.

Key Features:

Interactive global K_d map with customizable region.
Integration of PFAS producers, industrial sites, airports, and wastewater treatment plants.
Ability to upload site-specific soil property data (latitude/longitude) for localized K_d predictions.

The tool is in beta release, with the official launch scheduled for August 2025. Ongoing development will expand datasets, improve model accuracy, and add advanced risk indicators.

This platform is powered by research published in: Environmental Science & Technology (ACS Publications) .
