Welcome to the Drinking Water Treatability Database

The Drinking Water Treatability Database (TDB) presents referenced

information on the control of contaminants in drinking water. It allows

drinking water utilities, first responders to spills or emergencies,

treatment process designers, research organizations, academicians,

regulators and others to access referenced information gathered from

thousands of literature sources and assembled on one site. Over time, the

TDB will expand to include over 200 regulated and unregulated

contaminants and their contaminant properties. It includes more than 25

treatment processes used by drinking water utilities. The literature

includes bench-, pilot-, and full-scale studies of surface waters, ground

waters and laboratory waters. The literature includes peer-reviewed journals and conferences,

other conferences and symposia, research reports, theses, and dissertations. By adding new

contaminants and by upgrading references on existing contaminants, the TDB will always be a

current source of information on drinking water contaminant control. 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. The Help page will aid you in navigating the TDB.

Future Upgrades to the

Drinking Water Treatability

Database

Each year, as resources allow,

the number of contaminants in

the TDB will increase to include

other regulated and

unregulated drinking water

contaminants. It will also

upgrade information on

contaminants already in the

TDB to keep it current. The

bottom of each page indicates

when additions and upgrades

were last incorporated into the

TDB. Each contaminant

Overview page indicates the

most recent literature search

date for the contaminant. View

a List of Future Contaminants

anticipated for the next

upgrade and the anticipated

upgrade date.
