Laboratory Analytical Capability Inventory

Turnaround Times - Routine turnaround time is 35 days. Contact the Region 6 Sample Control Center for quicker turnaround times.

Concentration Ranges - The Region 6 Environmental Services Branch Laboratory does not routinely analyze % level samples, however % level analyses can be accommodated. Please contact the Region 6 Sample Control Center.

Region 6 Environmental Services Assistance Team (ESAT) - Region 6 ESAT assists with sample preparation activities and limited analytical support.

The SW-846 methods and other documents can now be viewed and/or printed using the Adobe Acrobat Reader. You may download the reader for free Exit EPA if you do not have Adobe Acrobat on your computer.
