Due to a lapse in appropriations, EPA websites will not be regularly updated. In the event of an environmental emergency imminently threatening the safety of human life or where necessary to protect certain property, the EPA website will be updated with appropriate information. Please note that all information on the EPA website may not be up to date, and transactions and inquiries submitted to the EPA website may not be processed or responded to until appropriations are enacted.

EPA Region 6 Laboratory Method Specific Analytical Capabilities with Sample Concentration Range

The EPA does not accept samples from the public and we do not reccomend or endorse commerical laboratories.

On this page


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 per cent (%) level samples, however per cent (%) 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.
