ECHO provides integrated compliance and enforcement information for about 800,000 regulated facilities nationwide. Its features range from simple to advanced, catering to users who want to conduct broad analyses as well as those who need to perform complex searches. Enforcement and compliance data are available for air emissions, surface water discharges, hazardous waste, and drinking water systems. ECHO includes EPA, state, local and tribal environmental agency compliance and enforcement records that are contained in EPA national databases. ECHO also incorporates many EPA environmental data sets to provide additional context for analyses.

The Environmental Protection Agency's Enforcement and Compliance History Online (ECHO) website provides customizable and downloadable information about environmental inspections, violations, and enforcement actions for EPA-regulated facilities related to the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act, and Safe Drinking Water Act. These data are updated weekly as part of the ECHO data refresh, and ECHO offers many user-friendly options to explore data, including: • Facility Search: ECHO information is searchable by varied criteria, including location, facility type, and compliance status. Search results are customizable and downloadable. • Comparative Maps and State Dashboards: These tools offer aggregated information about facility compliance status, regulatory agency compliance monitoring, and enforcement activity at the national and state level. • Bulk Data Downloads: One of ECHO’s most popular features is the ability to work offline by downloading large data sets. Users can take advantage of the ECHO Exporter, which provides summary information about each facility in comma-separated values (csv) file format, or download data sets by program as zip files.

The EchoNotes Structured Database derived from MIMIC-III (ECHO-NOTE2NUM) is a structured echocardiogram database derived from 43,472 observational notes obtained during echocardiogram studies conducted in the intensive care unit at the Beth Israel Deaconess Medical Center between 2001 and 2012. The database encompasses various aspects of cardiac structure and function, including cavity size, wall thickness, systolic and diastolic function, valve regurgitation and stenosis, as well as pulmonary pressures. To facilitate extensive data analysis, the clinical notes were transformed into a structured numerical format. Within each echocardiogram report sentence, specific words or phrases were identified to describe abnormal findings, and a severity staging system using numeric categories was established. This large publicly-accessible database of structured echocardiogram data holds significant potential as a tool to investigate cardiovascular disease in the intensive care unit.

The Facility Registry Service (FRS) provides quality facility data to support EPA's mission of protecting human health and the environment by identifying and geospatially locating facilities, sites, or places subject to environmental regulations of environmental interest.

We present MIMICEchoQA, a benchmark dataset for echocardiogram-based question answering, built from the publicly available MIMIC-IV-ECHO database. Each echocardiographic study was paired with the closest discharge summary within a 7-day window, and the transthoracic echocardiography (TTE) and ECHO sections were extracted to serve as proxies for cardiologist-authored diagnostic reports. DICOM videos were converted to .mp4 format, and a language model was used to generate multi-turn, closed-ended Q/A pairs grounded in these reports. To ensure anatomical consistency, a view classification model was used to label each video by its echocardiographic view (e.g., A4C, A3C), enabling the filtering of questions referencing structures not visible in the corresponding video. All generated Q/A pairs were manually reviewed by two board-certified cardiologists to ensure clinical validity. The final dataset consists of 622 high-quality, view-consistent Q/A pairs aligned with real-world echocardiogram videos, offering a valuable resource for developing and evaluating models in echocardiographic visual question answering.

Functional correlations of the medial septum/diagonal band of Broca (MS/DB, Ch123; Zaborszky et al., 2008). Image derived (via one sample t-test) from single-subject functional correlation Z-maps; single subject maps were derived from multi-echo data using multi-echo independent components regression (ME-ICR, Kundu et al., 2013). This is a partial correlation map -- data at the subject level were orthogonalized with respect to the nucleus basalis of Meynert (NBM, Ch4; Zaborszky et al., 2008).

This data release contains measured streamflow data from U.S. Geological Survey (USGS) streamgages and reported wastewater data from wastewater treatment plants (WWTP) discharge monitoring reports (DMRs) within the Potomac River watershed between October 1, 2021 and September 30, 2024. Mean monthly streamflow data was obtained from 117 USGS streamgages (Table1_Streamgages.csv). Average monthly reported wastewater discharge volumes to surface water were obtained from National Pollutant Discharge Elimination System (NPDES) permits using the United States Environmental Protection Agency’s (USEPA) Environment and Compliance History Online (ECHO) database to obtain DMRs from the Integrated Compliance Information System National Pollutant Discharge Elimination System (ICIS-NPDES). Quality assurance procedures that were used to avoid inclusion of inaccurate data that can be reported on DMRs (Table2_WWTP_DMRs.csv) are documented within the Process Step fields of the metadata. At each streamgage the average monthly accumulated wastewater percentage (ACCWW) was calculated by dividing the total amount of reported wastewater upstream of the streamgage by the measured amount of streamflow (Table3_Streamgage_ACCWW.csv) following similar methods described in Miller and others (2024) and Barber and others (2025). The ACCWW calculations were computed monthly at each streamgage using reported total wastewater discharge, municipal wastewater discharge, and municipal-plus-industrial per- and polyfluoroalkyl substances (PFAS) wastewater discharge which includes municipal wastewater in addition to wastewater from industrial WWTPs that are potential PFAS handling industry sectors defined by the USEPA (2023). The term ‘municipal’ is used here to represent NPDES-permitted facilities with the Standard Industrial Classification code 4952 (‘sewerage systems’) and 'industrial' refers to permitted facilities with Standard Industrial Classification codes other than 4952. Monthly predicted environmental concentrations and constituent loads (i.e. mass fluxes) of eight PFAS and 14 pesticides were estimated at each streamgage following methodology presented by Barber and others (2025) and Miller and others (2024). Monthly PFAS loads were computed by multiplying the discharge volumes from municipal and industrial WWTPs that are potential PFAS handling industry sectors by the median PFAS concentrations measured and reported in Barber and others (2025). Monthly pesticide loads were computed by multiplying the discharge volumes from municipal WWTPs by the median pesticide concentrations reported in Miller and others (2024). Wastewater effluent concentrations from Miller and others (2024) and Barber and others (2025) are provided in Table4_Parameters.csv. Monthly predicted constituent loads from wastewater were summed from WWTPs that discharged to every National Hydrography Dataset Version 2.1 (NHDPlus V2; USEPA, 2012) stream segment Common Identifier (COMID) upstream of each streamgage, not including the COMID where the streamgage was located, to calculate the predicted monthly load at each streamgage (Table5_Streamgage_Parameter_Predictions.csv). Predicted monthly concentrations from wastewater were calculated by dividing the predicted monthly load by measured monthly streamflow at each streamgage (Table5_Streamgage_Parameter_Predictions.csv).
