Water Quality Data
Access groundwater quality data across Texas using interactive tools and reports.
Reports are designed to view a select set of information in the GWDB, not for viewing all records in the database. Reports allow the user to select or enter certain information to obtain records for that specific criteria. There is an option to export the reports to several different formats; although the reports are optimized for viewing as PDF and CSV formats. Exported PDF page size is 8.5" x 11"
For more information on how to navigate the groundwater reports, download the Explanation of the toolbar.
