Cover:  The cover map is a national summary of the 1998 polluted waters.
 The map represents threatened and impaired streams, rivers, coastlines,
estuaries and lakes. The colors show the miles impaired /threatened within
 an 8-digit Hydrologic Unit Code (HUC), divided by the total number of
                     water miles within the HUC.

                    ATLAS OF AMERICA'S POLLUTED WATERS
   The maps in this atlas depict the waters within each state that do not meet state water quality standards.
States listed these waters in their most recent submission to EPA, generally in 1998, as required by section
303(d) of the Clean Water Act. This provision of the Clean Water Act requires a "Total Maximum Daily
Load" or TMDL for each listed water. There are more than 20,000 such waters identified nationally,
comprising more than 3 00,000 miles of rivers and streams and more than 5 million acres of lakes. The over-
whelming maj ority of Americans—over 218 million—live within ten miles of a polluted waterbody.

   Each state map includes a bar chart of the combined number of miles of streams, rivers, and coastal
shoreline or acres of lakes, estuaries and wetlands that do not meet state standards, and the pollutant that is
causing the impairment. The pollutants most frequently identified as causing water pollution include
sediments, excess nutrients, and harmful pathogens. Toxics, including metals, mercury and pesticides, also
contribute to these impairments.

   A TMDL is a pollution budget for a specific river, lake or stream. It is a quantitative estimate of what
it takes to achieve state water quality goals in polluted waters. States review water quality conditions and
identify specific waters that are polluted and work with local governments and interested parties in a
cooperative, bottom-up process to develop TMDLs. In the TMDL process, states and local interests work
together to allocate pollution reduction responsibility among sources and determine the  most common
sense, cost-effective way to address the specific problems of a particular waterbody.

   EPA has proposed to strengthen the TMDL program, first authorized in the 1972 Clean Water Act, to
clean up waters in communities across the country.
