In most cases, there is only one Organization ID per state, except where tribes submit geospatial data to ATTAINS. orgtype Indicates whether an Organization is a State or a Tribe tas303d Indicates whether an Organization has Treatment in a Similar Manner as a State (TAS) for Clean Water Act Section 303(d). organizationname The name of the Organization. reportingcycle Clean Water Act Sections 303(d) and 305(b), or the Integrated Report (IR) is due each even numbered year. This refers to the most recent reporting cycle of the assessment decisions summarized in the geospatial attribute data. assessmentunitidentifier States assess the quality of their surface waters and delineate them into Assessment Units. The Assessment Unit Identifier is the unique identifier for the water or portion of water (such as a section of a stream) within the Organization. assmnt_joinkey A field that can be used to join the flattened attribute table with the geospatial data. assessmentunitname The name assigned to the Assessment Unit Identifier by the state, territory, or tribe. This does not need to be unique. waterbodyreportlink A link to the Assessment Unit's Waterbody Report in How's My Waterway, which has more information about the water, including the Assessment determinations for individual Uses (rather than Use Group) and Parameters (rather than Parameter Group). ircategory The overall EPA Integrated Reporting (IR) Category for the Assessment Unit. For more information about IR Category, see Integrated Reporting Guidance under CWA Sections 303(d), 305(b), and 314 (https://www.epa.gov/tmdl/integrated-reporting-guidance-under-cwa-sections-303d-305b-and-314). overallstatus The summary of the Assessment Unit (Fully Supporting, Not Supporting, Insufficient Information or Not Assessed.) This is more generic than EPA IR Category. The EPA IR Category is only calculated for Organizations that have TAS for 303(d). The Overall Status is calculated for all Organizations. isassessed If the state has monitored a water and made an Assessment decision about the Assessment Unit, it is considered Assessed. If the state has defined the Assessment Unit but has not yet monitored and assessed it, then it is Not Assessed. isimpaired If any part of the Assessment Unit fails to meet its water quality standards, it is calculated as impaired. isthreatened Threatened means that one or more Uses is Fully Supporting but experiencing a declining trend and likely to become impaired in the next reporting cycle. Waters that are Threatened are part of the Clean Water Act Section 303(d) list, unless a TMDL has been created for them. A null value is the same as isThreatened = 'N'. on303dlist If the Assessment Unit is impaired by a pollutant and still needs to be addressed by a TMDL or other pollution control measure, it falls on the Clean Water Act (CWA) Section 303(d) List (which is also known as EPA IR Category 5). Note: This does not include all impaired waters. For example, Assessment Units that are impaired but already have a TMDL would fall into EPA IR Category 4a, and would not be on the CWA Section 303(d) list. hastmdl If the Assessment Unit has a Total Maximum Daily Load associated with it, then it will be marked as yes, it has a TMDL. This flag reflects the data that were current as of the most recent Integrated Report Assessment cycle submission to EPA. If a TMDL has been finalized since that cycle submission, it will not be reflected here. Note: The Assessment Unit may still need a TMDL for another pollutant. has4bplan If the Assessment Unit has a Category 4b Restoration Approach Action associated with it, then it will be marked as yes. This flag reflects the data that were current as of the most recent Integrated Report Assessment cycle submission to EPA. If an Action has been finalized since that cycle submission, it will not be reflected here. Note: The Assessment Unit may still need an Action (TMDL, 4b Restoration Approach, Alternative Restoration Approach or Protection Approach) for another Parameter. hasalternativeplan If the Assessment Unit has an Alternative Restoration Approach Action associated with it, then it will be marked as yes. This flag reflects the data that were current as of the most recent Integrated Report Assessment cycle submission to EPA. If an Action has been finalized since that cycle submission, it will not be reflected here. Note: The Assessment Unit may still need an Action (TMDL, 4b Restoration Approach, Alternative Restoration Approach or Protection Approach) for another Parameter. hasprotectionplan If the Assessment Unit has a Protection Approach Action associated with it, then it will be marked as yes. This flag reflects the data that were current as of the most recent Integrated Report Assessment cycle submission to EPA. If an Action has been finalized since that cycle submission, it will not be reflected here. Note: The Assessment Unit may still need an Action (TMDL, 4b Restoration Approach, Alternative Restoration Approach or Protection Approach) for another Parameter. visionpriority303d This indicates whether the Assessment Unit ID is designated as part of the Clean Water Act Section 303(d) Vision Priority waters. cultural_use This is a Use Group that includes any tribal Uses that pertain to cultural heritage in ATTAINS. drinkingwater_use This is a Use Group that includes any state Uses that have been designated for Drinking Water in ATTAINS. ecological_use This is a Use Group that includes any state Uses that pertain to the health of aquatic life in ATTAINS. fishconsumption_use This is a Use Group that includes any state Uses that pertain to fish or shelfish consumption in ATTAINS. recreation_use This is a Use Group that includes any state Uses that pertain to recreation (such as swimming or boating) in ATTAINS. other_use This is a Use Group that includes any state Uses that do not fit into one of the other Use Groups. algal_growth This is a Parameter Group that includes parameters such as: Algae and Chlorophyll-a. ammonia This is a Parameter Group that includes parameters such as: various forms of Ammonia. biotoxins This is a Parameter Group that includes parameters such as: Biotoxins and Cyanobacteria. cause_unknown This is a Parameter Group that includes parameters such as: Cause Unknown.
