This table report shows, for a portion of the
Missouri river: the designated uses, and
definitions from the state WQS. For Missouri,
the WQSDB also shows selected numerical
limits for chemical concentrations in the water
that need to be met to support these designated
uses. For other states, tribes, or territories, you
can get criteria information from the full text
copy of the state's WQS.

Water Quality Standards
Database (WQSDB)

The Water Quality Standards Database (WQSDB) is
being developed to display water quality standards
(WQS), including designated uses and criteria, for
the Nation's surface waters. The database began as a
prototype and has evolved into the National
WQSDB containing designated use information for
28 jurisdictions. The following 26 states, one U.S
Territory, and one Indian Tribe have been approved
for internet display: Arizona, Colorado, Connecticut,
Delaware, District of Columbia, Florida, Idaho,
Illinois, Iowa, Kentucky, Louisiana, Missouri,
Mississippi, Montana, Nebraska, Nevada, New
Mexico, North Dakota. Oklahoma, Rhode Island,
South Carolina, South Dakota, Tennessee, Texas,
Utah, West Virginia, the U.S. Virgin Islands, and the
Confederated Salish and Kootenai Tribes. Work is
progressing to include the remaining states, tribes,
and territories. Once completed, they will be
included as part of semi-annual updates to the

WQSDB Overview
For an introduction to the WQS Program, click on
"Basic information," then "History," and then
"Introduction to WQS," or go to:
The source information for the WQSDB is obtained
from each State's WQS regulations. Under the Clean
Water Act, each state is required to set water quality
standards and to identify a designated use for each
body of water in that state. The designated use, such
as drinking water supply or recreation, provides the
regulatory goal for a waterbody and defines its level
of protection.
These standards vary from state to state (e.g., some
states group many designated uses in to classes, e.g.,
Class A); while other states specify the use, such as
drinking water or primary contact recreation.
In addition to a designated uses, criteria have been
added for Missouri and Mississippi as pilots.
Currently, criteria information is being limited to
numeric criteria for priority pollutants and selected
non-priority pollutants. Inclusion of criteria
information will enable the database to support
complex queries involving criteria and uses on
specific waterbodies on stream segments.
The full text of the WQS for each state, tribe, and
territory is assembled on EPA's website. New or
revised WQS that have been adopted by the States,
Tribes, or Territories; and approved by EPA, will be
updated periodically; see http/www. epct. sov/ost/wqs.
The WQSDB information can also be found using
maps in EPA's EnviroMapper. EnviroMapper for
Water is a web-based Geographic Information
System (GIS) application that dynamically displays
information about bodies of water in the U.S. This
interactive tool allows you to create customized
maps portraying the nation's surface waters along
with a collection of environmental data; see

WQSDB Reports - Standard Reports
There are currently six WQSDB reports:
	Designated Use and Waterbody Information by
State: This report is a summary of designated use
and waterbody information.
	Designated Use and Waterbody Information
Across States: This report relates designated use
information across States.
	Designated Use and Class Information by
National DU: This report relates States
designated use information to National Designated
Use Information.
	State Numeric Criteria: This report identifies the
State numeric criteria for each designated use.
(MO and MS)
	EPA Numeric Criteria: This report lists the
recommended EPA numeric criteria.
	State vs. EPA Numeric Criteria: This report
compares State numeric criteria with the
recommended EPA numeric criteria. (MO and
