About the Database

The PFAS Thermal Treatment Database (PFASTT) is a growing database that contains over 2,000 records of 80 sources documenting the treatability of PFAS in different media via various thermal processes. The PFASTT was created as a response to the need for a centralized database to record reliable references for researchers and general public. Sources cited in the database include peer reviewed and non-peer reviewed journals, government reports, conference reports, and other types of publications.

Sources entered focused on the following thermal treatment processes:

• Calcining,
• Granular activated carbon reactivation,
• Gasification,
• Hydrothermal,
• Incineration,
• Indirect thermal desorption,
• Pyrolysis, and
• Smoldering.

The database does not include low temperature processes or processes where the primary treatment mechanism is non-thermal. For example, the database does not include data on persulfate, plasma, electrochemical, or photolysis treatment processes.

Navigating the Database

Use the menu at the top of the page to navigate the database:

• The References Report tabulates summary-level information for each reference in the database, including identifying and summarizing the scope covered by each reference.
• The All Data Report tabulates all the data in the database at the level of individual analytes in a concise, screen-readable format.
• The All Data Download provides the same data as the data report, but with all columns separated and expanded to facilitate downloading and manipulating the data in external applications (e.g., Excel).
• The Glossary explains each field in the database.

Users can also view data by attribute: References, Scope, and Conditions.

Database Structure

The data structure of the PFASTT is separated into three levels beyond the initial reference:

• Scope,
• Condition, and
• Thermal Treatment Results.

This database structure is depicted below.
