U.S. environment, energy and climate data sources
Candidate monitored air quality, state energy and water/climate products with explicit geographic and unit distinctions.
Catalog-only · documented candidate; observations not integrated
Air and water measure different systems
EPA AirData provides monitored air-quality resources. A future integration must retain monitor locations, pollutants, averaging periods, reporting completeness and standards. A county without a monitor cannot be labeled clean merely because no reading is available. Final historical data are distinct from current-condition services.
Water resources include surface-water measurements, public drinking-water systems and regulatory records. Water-system boundaries may cross county boundaries. A recorded violation is not an exposure measurement for every resident, while an absence of reported violations is not a universal safety guarantee.
Energy and climate definitions
EIA’s State Energy Data System covers state-level annual energy concepts. Total energy is not electricity, capacity is not generation, and retail prices are not household bills. An electricity mix needs a clear statement about facilities inside the state versus consumption by residents. Fuel units and approved conversions must be explicit.
Climate observations, historical normals, anomalies, projections and modeled hazards require separate baselines and methods. Weather events do not alone establish a climate trend. Disaster declarations, losses and assistance payments answer different questions; recorded assistance is not total economic damage.
Catalog-only status
EPA and EIA documentation were reviewed as source candidates. No monitored air-quality, energy, water, climate or hazard observations are maintained by this release. NOAA and FEMA endpoints and exact file coverage require further validation. The environment/infrastructure hub’s numeric coverage is ACS subscriptions, vehicle availability and commuting.
Before integrating any product, validate current endpoints, units, geographic methods, periods, publication rights and missingness. Do not assign county hazard values to individual properties or use area-level environmental indicators as personal medical advice.
