The Assessment, Total Maximum Daily Load (TMDL) Tracking and Implementation System (ATTAINS) is an online system for accessing information about the conditions in the Nation’s surface waters.
Overview of ATTAINS
The Clean Water Act requires states, territories and authorized tribes (states for brevity) to monitor water pollution and report to EPA every two years on the waters they have evaluated. This process is called assessment. Part of this process is deciding which waters do not meet water quality standards because they are too polluted. These degraded waters are called impaired (polluted enough to require action) and are placed on a State list for future actions to reduce pollution.
This information reported to EPA by states is available in ATTAINS. The information is made available via the ATTAINS web reports, as well as through other EPA tools. The ATTAINS web reports provide users with easy access to view the information on the status of waters at the national, state and site-specific waterbody levels. To access this information, click the Get Data/Tool tab above.
State, Tribal, and EPA partners will find information about how to access ATTAINS to submit data by clicking on the Upload Data tab above.

Access ATTAINS Data
Click here to access ATTAINS web reports - The ATTAINS data are presented online in two main report formats (integrated and separate), which reflect how States provide their data to EPA.
Other Tools that Incorporate ATTAINS Data
The following EPA resources also provide access to ATTAINS data:
- Ask WATERS: Ask WATERS answers multi-program questions that draw on information from the databases linked through WATERS.
- The Simple Query answers frequently asked questions about WATERS data. Its easy-to-use interface returns summary, detailed and graphical results in an easy-to-read format.
- The Expert Query is a powerful tool consisting of fully interactive database views for users requiring more specific data analyses.
- ATTAINS National Geospatial Downloads: Precut geospatial extracts containing selected ATTAINS database attributes; offered in various GIS formats.
- Environmental Dataset Gateway (EDG) Clip N Ship: An online tool that presents EPA data in a map viewer and allows users to view the data, select an area of interest, and choose an output format to save the content locally.
- How’s My Waterway: A mobile web app and website that helps people find information on the condition of their local waterways using a smart phone, tablet, or desktop computer. It makes science-based water quality information accessible and understandable for everyone.
- My WATERS Mapper: MyWATERS Mapper dynamically displays snapshots of EPA Office of Water program data.
- Reach Address Database (RAD): The RAD stores reach address information for each Water Program feature that has been linked to the underlying surface water features in the National Hydrology Database Plus (NHDPlus) dataset. For the ATTAINS program, if States provide geospatial data that are associated with their Intergrated Reporting data, EPA processes the State geospatial data for submission to the RAD.
The ATTAINS system allows registered state or tribal users to create Assessment Units and upload assessment decisions about those Assessment Units for their organization. In addition, the ATTAINS system allows registered EPA users to provide comments about assessment decisions, and to review Clean Water Act Section 303(d) lists of impaired waters. Users may work directly with the web user interface, batch upload files within the user interface, or submit data via the Exchange Network data flow.
- Registered users may access the ATTAINS User Interface here.
- The How to Register for ATTAINS Fact Sheet explains the steps needed to obtain a User ID and get setup in the system.
- The How to Sign in to ATTAINS Fact Sheet explains how different users access the system.
- Contacts - If you need assistance with ATTAINS, start with your regional Data Management Coordinator (DMC). They can set up an ATTAINS account for you, and can answer many of your system-related questions.
ATTAINS Exchange Network Tools
- Resources regarding submitting data through the Exchange Network - ATTAINS data flowExitare available on the Exchange Network page.
- The Flow Configuration Document provides information on service end points
- The Data Exchange Template provides information on the required versus optional fields in ATTAINS
ATTAINS User Interface Tools
- Batch Upload Templates
- Assessment Unit Batch Upload Template (1 pg, 84 K, 12/20/2017) - This Excel template can be used to upload new Assessment Units or update information about existing Assessment Units through batch upload capability in the ATTAINS User Interface. The file allows users to provide information such as Assessment Unit ID and Assessment Unit Name, as well as Water Types, Locations and Monitoring Stations associated with the Assessment Unit.
- Assessment Batch Upload Template (1 pg, 96 K, 12/20/2017) - This Excel template can be used to upload Assessment decisions about Assessment Units. The file allows users to provide information on the last time the Assessment Unit was monitored and assessed. It also includes the Uses that apply to the Assessment Unit and the decisions about those Uses. It also includes the Parameters that were assessed and the decisions about the parameter (whether it was meeting criteria or a cause of impairment or an observed effect), and any Sources of impairment.
- Domain Values – Allowed values for restricted value fields in ATTAINS
- DOMAINS.xlsx(1 pg, 3 MB, 06/04/2018) – This file is connected to ATTAINS Services. It can be updated to the latest domain values by downloading the file, going to the Data tab in the Excel Ribbon and clicking on “Refresh All”. Note: In order to refresh the spreadsheet to the latest values, you must have Office 2016 or later.
- Transitioning from ADB to ATTAINS
- TN_ATTAINS_BATCH_from_ADB.zip(1 pg, 8 MB, 02/08/2018) – Tennessee developed some queries for the Assessment Database (ADB) that create Batch Upload queries to help populate ATTAINS.
