Environmental Services

PTS Laboratories is the world leader in handling and measuring unconsolidated soils and sediments. Our experienced staff routinely deals with the full range of soil types expected from today's complex environmental sites including engineered-materials, man-made materials, ocean, lacustrine and fluvial sediments. We are experts at measuring LNAPL and DNAPL Mobility parameters. PTS holds a valid Soil Import Permit from the USDA and routinely receives soil samples and core from outside the US.

In order to better serve our customers PTS Laboratories is consolidating our Environmental Services Division with our Oil Field Services laboratory located in Houston, Texas.  All Environmental Services testing and analyses will be conducted in our 22,000 square foot facility beginning July 10, 2017.  Samples should be shipped to the PTS Houston facility at the following address:
