Expanded Compound Testing

Montrose Environmental Group continues to set industry standards for the breadth and scope of its compound testing. Through Enthalpy Analytical, we conduct ultratrace analyses to quantify the presence of dioxins, PCB congeners, and other compounds at their lowest detectable levels in the environment.

In the near term, we will provide analyses that reports all 136 tetra-octa chlorinated dioxins and furans, facilitating the most advanced forensic analyses of sample results possible, and expand the range of compound testing we offer to customer across the US.
