This page is no longer in use. Previously, it provided users with the ability to build queries for accessing surface water quality monitoring data in Texas. This tool is no longer updated. Please use the CRP Data Tool or the SWQM Data Tool.
The data that is available through this query includes data that was collected under a TCEQ-approved quality assurance project plan and met the requirements of NELAP (National Environmental Laboratory Accreditation Program, July 2008) for select laboratory analyses.
Use of the data query requires knowledge of the file structures and protocols of the state's surface water quality monitoring program. Information on file structures, code descriptions, and reporting requirements is provided in the Data Management Reference Guide.
Select one of each item (file type, year, and basin or segment). You will need to repeat each query to get both file types (event and result). Query results are returned in text files delimited with a "|" symbol. These two files can be imported into Excel or Access and related using the Tag ID. Due to time-out issues with Microsoft Internet Explorer, it is important to SAVE THE TEXT FILE as soon as possible, or some records may be deleted.
Select a file type
Select a year
Select a basin or segment (view maps of basins and segments)
Press to complete the query or to start over. (Save the file as soon as possible to prevent the loss of data.)
If you need assistance, or experience difficulty with queries run from this page, please e-mail firstname.lastname@example.org.
