ECHO will be unavailable for up to an hour on Sunday, February 14, while we perform system maintenance.

What's New

This is EPA's modernized Enforcement and Compliance History Online (ECHO) website. The original site (which was at was retired. It was launched in 2002 and processed two million queries a year, but could not easily support features like frequent data updates and web services. ECHO is frequently upgraded based on Agency priorities and user requests. New features are described below.

January 2015

Drinking Water Dashboard Enhanced

The Safe Drinking Water Act (SDWA) Dashboard (Drinking Water Dashboard) has been enhanced. A new "Advanced View" option lets users see graphs "filtered" on the basis of public water system type or size, source water category, or EPA Region. Another enhanced function is the user's ability to analyze the information sorted for all Indian country, for Indian country in a particular EPA region, and on a tribe-by-tribe basis. The Drinking Water Dashboard puts five years of drinking water compliance and enforcement data at the fingertips of anyone with Internet access. As before, the SDWA Dashboard provides an overview of how EPA, the Navajo Nation, and implementing states regulate public water systems. The dashboard offers information on the type and size of public water systems, on-site visits, and system violations. The public can use information on the dashboard to monitor the number of enforcement actions undertaken and the number of systems returned to compliance. The enhanced Drinking Water Dashboard continues EPA's commitment to sharing data with citizens in formats they can understand and use.

ECHO 2.0 Launched

The modernized version of EPA's Enforcement and Compliance History Online (ECHO) website, the Agency’s primary website for providing public access to regulatory compliance and enforcement data, was launched on December 3. ECHO is a go-to resource for information about environmental inspections, violations, and enforcement actions for more than 800,000 regulated facilities. The original site launched in 2002 and use increased steadily, providing answers to 2 million queries per year regarding environmental compliance and enforcement data.

President Obama cited ECHO as a model for transparency for other federal agencies to follow, and modernization helps the Agency meet requirements of recent transparency-related executive orders. The data in ECHO are updated every week and simplified navigation makes it easier to find information of interest. It’s built on a modern, flexible platform, allowing for improved mapping, viewing on mobile devices, and machine-readable data/web services. The new system also opens up greater possibilities for data transparency and integration in the future.

The central features of this release are cross-statute (multimedia) facility searching and state comparative maps and dashboards. Program-specific searching – like air, water, waste - and other features will be phased in to ECHO throughout 2014 until all key features from the previous system are replaced. A list of issues with the new site is maintained on the site's Website Known Issues page. Information about the modernization process also is maintained on the site. Send feedback to EPA about the site by clicking ECHO's Contact Us link.
