资源简介：
The "Federal Reporting Database System (FRDS)" is a centralized
database for information on public drinking water supplies,
including their compliance with monitoring requirements, maximum
contaminant levels (MCL), and other requirements of the Safe
Drinking Water Act (SDWA) Amendments of 1986. Data are used for
the Public Water System Supervision (PWSS) Program maintained by
the U.S. Environmental Protection Agency's (USEPA) Office of
Drinking Water. FRDS contains approximately 12 million records.
Information tracked includes: owner/operator name and address;
operational status; location; on-site visits; sources;
violations; enforcement and compliance actions; treatment;
variances and exemptions; area (county and population)served by
the system; and historical information. Additional information
is entered at each state's discretion. FRDS does not track
private wells or public water supplies excluded by the SDWA.
