Texas Environmental Data System (TEDS)

TEDS is a data management system for TCEQ remediation programs.

The TCEQ has launched the Texas Environmental Data System (TEDS) to capture analytical, geological, and spatial data on remediation sites in Texas.  The purpose of TEDS is to provide a data management system whereby data submitted electronically to the TCEQ are then utilized and evaluated in mapping and modeling software applications to better manage remediation sites on both an individual basis and regionally.  TEDS captures spatial, chemistry, and geologic data into a database which interfaces with other software, such as:

  • ArcGIS and Google Earth for mapping,
  • RockWorks for subsurface visualization,
  • LogPlot for detailed well logs,
  • Surfer for modeling, and
  • Other applications such as MS Excel and Adobe Acrobat.

TEDS will accept data on all types of remediation sites – Voluntary Cleanup Program sites, Petroleum Storage Tank program sites, Industrial and Hazardous Waste Corrective Action sites, Superfund sites, Dry Cleaner Remediation sites, and others. TCEQ project managers are using TEDS to conduct analysis of site data, including running custom reports, developing maps, and modeling.

How will data be loaded into TEDS?
The TCEQ is using software called EQuIS, from EarthSoft, Inc., as the data management system.  The data provider, typically the consultant, enters data from the laboratory and field work into a MS Excel spreadsheet; processes it through EarthSoft’s EQuIS Data Processor; and is sends it to the database electronically via the Web. EarthSoft’s EQuIS Data Processor is a free data checker that can be downloaded from the EarthSoft website or by using the link below. Specialized software is not required to submit data electronically.

The TEDS Instruction Manual for Data Providers explains how to setup a TEDS account, how to download the EQuIS Data Processor and TCEQ Format, and additional information on how to process and submit data.

What is the benefit of TEDS?
TCEQ project managers are using TEDS to conduct analysis of site data, including running custom reports, developing maps, and modeling. TEDS has numerous benefits for the agency and the regulated community, including:

  • The quality of data submitted will improve as data will be checked for proper format prior to submittal.
  • Site locations and contaminant plumes are easily mapped, as are water wells and surface water sampling points.
  • Project managers will be able to visualize and analyze contaminant plumes, leading to better and quicker decisions. Remediation sites can be evaluated on a regional or programmatic scale to better manage the sites and plan strategically within the remediation programs and with other agency programs.
Required use of SW-846 Method 5035

New Information

Beginning January 1, 2016, the TCEQ Remediation Division will require the use of United States Environmental Protection Agency (USEPA) SW846 Method 5035A, Purge-and-Trap and Extraction for Volatile Organics in Soil and Waste Samples, as amended, for the collection and preparation of solid samples for volatile organic compound (VOC) analysis using purge-and-trap technology.

The TCEQ Remediation Division guidance on Method 5035 has been updated and is available.
