Data Quality

The U.S. EPA, state regulatory agencies, and NPIRS are dedicated to delivering timely, accurate pesticide registration data to both our members and the public. As part of this shared commitment to data quality, NPIRS has implemented a reporting process for users to notify us of any data discrepancies found on our websites.

Data quality issues may arise during processing or may exist within the source data itself. When a report is submitted, NPIRS staff review the information to verify the nature and validity of the issue. If further action is required, the concern is forwarded to the U.S. EPA or the appropriate state regulatory agency for additional review and potential correction.

Please use the Data Quality Report Form on this page to provide the requested details, including a clear description of the issue. Fields marked with an asterisk (*) are required.
