Water Fluoridation Reporting System (WFRS)

Description

The Water Fluoridation Reporting System (WFRS) is a tool that helps states to manage the quality of their water fluoridation programs. WFRS information is also the basis for national reports that describe the percentage of the U.S. population who receive optimally fluoridated drinking water through public water systems.

Supplier

Centers for Disease Control and Prevention, National Center for Chronic Disease Prevention and Health Promotion (CDC/NCCDPHP)

Data Years Available

1998-present

Periodicity

Annual

Mode

N/A

Selected Content

Data about each water system include facility location, population served, fluoridation status, natural fluoridation concentrations, system type. Laboratory testing, dates of facility inspections, and other relevant information are also included.

Population covered

Public water systems in the United States.

Methodology

The WFRS database structure is modeled using the same data strategy and structure as the Environmental Protection Agency's (EPA) Safe Drinking Water Information System, which permits exchange of data and updates on utility system configurations. State fluoridation managers enter data into WFRS and generate reports for state program use.

Response rate and sample size

There are about 54,000 community water systems included in WRFS. Of these, about 16,500 systems are listed as either having fluoride levels that are adjusted, are naturally occurring, or are consecutively fluoridated (purchased from a neighboring system that has optimally fluoridated water).
