About the Online ATTAINS Integrated Reports

This guide describes the content (tables, charts, and other features) of the Integrated Report format of the ATTAINS web reports. The items are described in the order they appear in the website. For States that did not submit an Integrated Report to EPA, a different format is used; see About the Online ATTAINS Separate Impaired and Assessed Waters Reports. To see if a State provided Integrated or separate reports for recent reporting cycles, see Status of Available ATTAINS Data.

Water Quality Assessment Data for the State: Clickable list of all the tables and charts in the website for the state.

Total Assessed Waters for State: The extent to which the state's assessed waters support their uses, for each type of water (e.g., river and stream miles; lakes, reservoirs, and ponds acres), and the amount assessed by the state for the most recent reporting cycle (e.g., 2006, 2008). Assessed waters are those for which monitoring or other types of information have been used by the state to judge whether designated uses are being met. In order to be considered "good," it must meet all the uses for which it was assessed. It is considered "threatened" if it is meeting all assessed uses but if water quality conditions appear to be declining. It is considered "impaired" if any one of its assessed uses is not met. Information is also provided on restored waters and threatened and impaired waters TMDL development status.

Assessed Waters, Overall Water Quality Attainment for Rivers and Streams: The extent to which the state's assessed river and stream miles support their uses. A river and stream mile may be assessed for several different uses. In order to be considered "good," it must meet all the uses for which it was assessed. It is considered "threatened" if it is meeting all assessed uses but if water quality conditions appear to be declining. It is considered "impaired" if any one of its assessed uses is not met. River and stream miles assessed as threatened or impaired are also grouped by TMDL development status, which includes: TMDL completed, TMDL alternative, Non-pollutant, or TMDL needed.

Reasons for delisting waters include: TMDL approved or established by EPA (Category 4a), other pollution control requirements (Category 4b), Not caused by a pollutant (Category 4c), or data and/or information lacking to determine water quality status; original basis for listing was incorrect (Category 3). Reasons for WQS attainment include: applicable WQS attained, original basis for listing was incorrect; applicable WQS attained due to restoration activities; applicable WQS attained due to change in WQS; applicable WQS attained according to new assessment method; applicable WQS attained threatened water no longer threatened; or applicable WQS attained, reason for recovery unspecified.

Waterbody History Report: The 305(b) and 303(d) Waterbody History Reports provide reporting cycle and cause of impairment tracking information for individual waterbodies. Reporting cycle tracking refers to the waterbody ID changes, including those that pertain to resegmentation, that a waterbody has undergone throughout its history. Cause of impairment tracking refers to the cause of impairment terminology changes a cause of impairment may have undergone from one reporting cycle to the next reporting cycle (e.g., a cause of impairment identified as "pathogens" in the 2010 reporting cycle may be changed to "fecal coliform" in the 2012 reporting cycle). Where available, cause of impairment tracking also includes information about TMDL development status and attainment of water quality standards. Reporting cycle and cause of impairment tracking are stored separately for 305(b) assessment and 303(d) listed water decision data, and therefore they appear in separate reports, even when the waterbody being viewed is in a state report where the state submits integrated data. EPA started to collect 303(d) reporting cycle and cause of impairment tracking data in the 2008 reporting cycle; although some data from earlier reporting cycles exists, the information may not be complete. EPA started to collect 305(b) reporting cycle and cause of impairment tracking data in the 2010 reporting cycle. Reporting cycle and cause of impairment tracking data are optional and may not exist for all states or waterbodies.

Comparison Summary by Reporting Year: Tables organized by waterbody type that show the extent to which the state's assessed waters support their uses, and the amount assessed by the state for each reporting cycle (e.g., 2002, 2004, 2006). Assessed waters are those for which monitoring or other types of information have been used by the state to judge whether designated uses are being met. In order to be considered "good," it must meet all the uses for which it was assessed. It is considered "threatened" if it is meeting all assessed uses but if water quality conditions appear to be declining. It is considered "impaired" if any one of its assessed uses is not met. The second table for each waterbody type provides the TMDL development (TMDL completed, TMDL alternative, Non-pollutant, or TMDL needed) status for threatened and impaired waters.
