Office of Water Program Program Database Description
Water Quality Standards WQSDB The Water Quality Standards Database (WQSDB) contains information on the uses that have been designated for waterbodies. Examples of such uses are: drinking water supply, recreation, and fish protection. As part of a State's water quality standards, these designated uses provide a regulatory goal for the waterbody and define the level of protection assigned to it. WQS also includes the scientific criteria to support that use.
Integrated Reporting
305(b) Report and
303(d) List
ATTAINS The Assessment, TMDL Tracking and ImplementatioN System (ATTAINS) database contains information reported by the states to EPA about the conditions in their surface waters. The database is comprised of information on the attainment of water quality standards, sometimes referred to as the Clean Water Act Section 305(b) information; as well as the list of impaired waters that need a Total Maximum Daily Load (TMDL), sometimes referred to as the Clean Water Act Section 303(d) List. ATTAINS is a combination of what was formerly referred to as the National Assessment Database (NAD) and the National TMDL Tracking System (NTTS).
Water Quality Inventory
305(b) Report
NAD The National Assessment Database (NAD) contains information on the attainment of water quality standards. Assessed waters are classified as either Fully Supporting, Threatened, or Not Supporting their designated uses. This information is reported in the National Water Quality Inventory Report to Congress under Section 305(b) of the Clean Water Act.
Total Maximum Daily Load (TMDL)
303(d) List
TMDL Tracking System The Total Maximum Daily Load (TMDL) Tracking System contains information on waters that are Not Supporting their designated uses. These waters are listed by the state as impaired under Section 303(d) of the Clean Water Act. The status of TMDLs are also tracked. TMDLs are pollution control measures that reduce the discharge of pollutants into impaired waters.
Water Quality Monitoring STORET STORET (short for STOrage and RETrieval) is a repository for water quality, biological, and physical data and is used by state environmental agencies, EPA and other federal agencies, universities, private citizens, and many others. The Legacy Data Center, or LDC, contains historical water quality data dating back to the early part of the 20th century and collected up to the end of 1998.
NPDES Permits PCS Discharge of pollutants into waters of the United States is regulated under the National Pollutant Discharge Elimination System (NPDES), a mandated provision of the Clean Water Act. To assist with the regulation process, state and federal regulators use an information management system called the Permit Compliance System (PCS). PCS stores data about NPDES facilities, permits, compliance status, and enforcement activities for up to six years.
Safe Drinking Water SDWIS The Safe Drinking Water Act (SDWA) requires that states report to EPA information about public water systems and their violations of EPA's drinking water regulations. These regulations, and their enabling statutes, establish maximum contaminant levels, treatment techniques, and monitoring and reporting requirements to ensure that water provided to customers is safe for human consumption. This information is stored in SDWIS - Safe Drinking Water Information System.
Fish Consumption Advisories NLFWA The National Listing of Fish and Wildlife Advisories (NLFWA) database includes all available information describing state-, tribal-, and federally-issued fish consumption advisories in the United States and Canada.
Nonpoint Source Pollution GRTS The Section 319 Grants Reporting and Tracking System (GRTS) is the main reporting vehicle for the Section 319 program. GRTS enables EPA and States to describe the progress they have made in implementing the national Nonpoint Source (NPS) Pollution program. GRTS electronically tracks projects and activities funded with CWA Section 319(h) funds.
Nutrient Criteria Nutrient Criteria Database The Nutrient Criteria Database stores and analyzes nutrient water quality data, which will aid in the development of scientifically defensible numeric nutrient criteria. The ultimate use of the data is to derive ecoregional waterbody-specific numeric nutrient criteria.
BEACH program BEACH Watch The Beaches Environmental Assessment, Closure & Health BEACH Watch database provides information on whether a specific beach is being monitored for water quality, who is responsible for the monitoring, the pollutants that are being monitored, and if advisories or closures have been issued.
Vessel Sewage Discharge NDZ Vessel sewage discharge is regulated under Clean Water Act Section 312, which mandates the use of marine sanitation devices (on-board equipment for treating and discharging or storing sewage) on all commercial and recreational vessels that are equipped with installed toilets. Under Section 312 States may request a No-Discharge Zone (NDZ) designation that prohibits the discharge of sewage from all vessels into defined waters.
Clean Watersheds Needs Survey CWNS The Clean Watersheds Needs Survey (CWNS) provides information on publicly-owned wastewater collection and treatment facilities, facilities for control of sanitary sewer overflows (SSOs), combined sewer overflows (CSOs), stormwater control activities, nonpoint sources, and programs designed to protect the nation's estuaries. Information obtained from the survey is maintained in the CWNS database.
