Start Preamble


Environmental Protection Agency (EPA).


Notice of data availability and request for comment.


Notice of availability for a 30 day review and comment period is hereby given for six revised data standards—Well Information Data Standard, ESAR: Field Activity, ESAR: Monitoring Location, ESAR: Analysis and Results, ESAR: Project and Quality Assurance and Quality Control Data Standards.

ESAR, along with the suite of related data standards, enhances the availability and exchange of monitoring data used for environmental decision-making. Biological related data elements are largely missing from ESAR and given the importance and interest in these data, the Environmental Council of States (ECOS) and US EPA worked together to adapt/incorporate two Advisory Committee on Water Information (ACWI) approved standards into ESAR.

The ACWI approved Water Quality Data Elements for Reporting Results of Populations/Community Biological Assessments and Toxicity Test Analyses (TOX and POP) has been adapted for inclusion in ESAR

Standards are intended for use in environmental data exchange among States, Tribal entities and U.S. EPA. They are not meant to dictate or limit data an agency chooses to collect for its own internal purposes. Adoption of a data standard should be interpreted to mean that revisions to databases or information systems are required. What the adoption does mean is that formats for sharing data with Exchange Network (EN) partners will change because the EN has adopted Shared Schema Components (SSCs) based on the data standards. The SSCs are available on the Exchange Network Web site at:

The revised data standards are available through the Docket system as indicated above and at:​datastandards, and​standards.
