ECSI Downloadable Files

The Environmental Cleanup Site Information Database will be retired as we modernize to Your DEQ Online starting April 16, 2024. Learn more.

The "ECSI Data Files" link on this page is a self-extracting zip file that contains 32 tables of data from the Environmental Cleanup Site Information database. The tables are formatted as comma-delimited text, and include all data fields in ECSI that hold important site information. DEQ updates the files and posts them to this page on the first day of each month.

ECSI is a complex relational database with many interrelated data elements. Therefore, DEQ recommends that users understand the tables’ data types and interrelationships before downloading and using the data. Two documents on this page, ECSI Table Descriptions and Entity Relationship Diagram, provide this information.

    Note: Double quotes (“) within these comma-delimited files can cause columns to split into multiple columns unexpectedly. To prevent this, double quotes within Comments columns of tables in these zipped files have been replaced with <quot>. To return the original formatting, users need to employ a manual find-and-replace feature to replace <quot> with the double quote (“).
