The Drinking Water Treatability Database (TDB) presents referenced information on the control of contaminants in drinking water. It provides users—including drinking water utilities, primacy agencies, first responders to spills or emergencies, treatment process designers, research organizations, academicians, and others—with current information on more than 30 treatment processes and over 120 regulated and unregulated contaminants, including 26 PFAS chemicals. The referenced information in the TDB comprises bench-, pilot-, and full-scale studies of surface, ground, and laboratory waters gathered from thousands of literature sources, including peer-reviewed journals and conferences, other conferences and symposia, research reports, theses, and dissertations. Over time, the TDB will expand to include over 200 regulated and unregulated contaminants and their contaminant properties. Visit the About the TDB page for more information.
The TDB offers many features leading to the Data tab which is the heart of the TDB. After selecting a contaminant (Find a Contaminant), you will find a Treatment Processes tab that will present the list of treatment processes for which literature on the control of the contaminant was located. Selecting a treatment process, you will find a Data tab, like that shown below, that presents reference information, log or percent removal, water quality conditions and treatment process operational parameters. In the navigation menu you will see a menu option called Help. If you click on Help you will see all of the pages in TDB listed in a drop down menu. When you select one of the options you will be taken to the help section for that particular page.
