Use ECHO and the Detailed Facility Report to vet sites in M&A diligence or permit reviews.

Air Quality Forecasting

Combine AQS observations with NWS / EPA AirNow forecasts for public-facing apps.

Hazardous Waste Tracking

Integrate the e-Manifest API into waste generator and transporter logistics systems.

Drinking Water Reporting

Use SDWIS via ECHO to monitor public water system violations and inform consumer notifications.

Climate / Decarbonization

Pull CAM emissions and GHGRP data for power-sector carbon analytics and FrEDI-style impact modeling.

Chemical Risk Assessment

Use CTX (Chemical, Hazard, Bioactivity, Exposure) data plus ToxCast/ToxRefDB to triage substances.

Watershed Restoration

Combine ATTAINS impairments, How's My Waterway, and StreamCat metrics for restoration planning.

Integrations

api.data.gov

Government-wide API management front-door for several EPA APIs with X-API-Key sign-up flow.

data.gov

Federal open data catalog cross-listing every EPA-published dataset.

NAAS / CDX

EPA's Network Authentication & Authorization Services for credentialed submissions (FRS Submit, e-Manifest, NEI).

State Environmental Agencies

State primacy programs forward data into AQS, ECHO, SDWIS, RCRAInfo, and TRI.

USGS, NOAA, USDA

Cross-agency data sharing for water, weather, and agricultural environmental data.

Solutions

Public-Facing Awareness

How's My Waterway, AirNow, and Insect Repellents are designed for consumer use.

Regulatory Compliance

ECHO, RCRAInfo, NPDES eDMR, e-Manifest support regulated-entity reporting workflows.

Scientific Research

CTX, ToxCast, ToxRefDB, EPA HTTK, FrEDI underpin chemical safety and climate research.

Internal Government

FRS Submit, SoR, Grants, CSB Rebate APIs support EPA program operations and grantees.
