The U.S. Environmental Protection Agency (EPA) has announced an update to its Drinking Water Treatability Database with new treatment options and scientific references for per- and polyfluoroalkyl substances (PFAS). This update is another example of the Trump Administration delivering on an important commitment under EPA’s first-of-its-kind PFAS Action Plan. The database update will further help states, tribes, and local governments, as well as water utilities, make better decisions to manage PFAS in their communities.
“The latest addition of four PFAS compounds and 20 new scientific references to the Drinking Water Treatability Database increases our depth of scientific knowledge on this emerging chemical of concern. The update serves as an important tool for states, tribes and communities across the country as they can now use these new treatment technologies to better protect public health and manage PFAS in drinking water,” said EPA Administrator Andrew Wheeler.
In this most recent update, EPA added treatment and contaminant information about four new PFAS compounds. This update brings the total number of PFAS compounds in the database to 26, including PFOA and PFOS. Researchers have also added 20 new scientific references to the existing PFAS entries, which increases the depth of scientific knowledge available in the database. The four new PFAS compounds are:
- Difuoro(perfluoromethoxy) acetic acid, also known as Perfluoro-2-methoxyacetic acid
- Perfluoro-3,5-dioxahexanoic acid
- Perfluoro-3,5,7-trioxaoctanoic acid
- Perfluoropropane sulfonate
The Drinking Water Treatability Database presents an overview of the properties of different contaminants and possible treatment processes to remove them from drinking water. Water utility managers, water treatment experts, states, tribes, local governments, researchers, and others can use this new and updated information to help treat PFAS in drinking water systems to protect the health of communities across the nation.
The information included in the database is supported by scientific references, such as journal articles, conference proceedings, reports, and webinars with treatability data. The release of this information continues to address the challenges laid out in the PFAS Action Plan.
About The Drinking Water Treatability Database
The Drinking Water Treatability Database contains information on a wide range of different contaminants, not just PFAS. EPA researchers continue to expand and improve information in the database.
