Changes in our service operations

Thank you for part­nering with Columbia Labs for your envi­ron­mental testing needs.

Due to industry-wide resource limi­ta­tions and legal concerns, we are changing our approach to histor­ical sampling needs.

We ask that you inform us of your sampling needs by requesting indi­vidual sampling events via our chain of custody (COC), attached here. Our Real Estate Kit COC, Coliform COC, and General Envi­ron­mental COC are also avail­able in our sample submis­sion page.

Please email Mark Leed at Mark.​Leed@​tentamus.​com, with any questions.
