Soil Vapour Specialists

Soil vapour regulations are emerging in many North American jurisdictions. Thermal desorption (TD) tubes provide a cost effective, practical and technically sound approach for collecting and analyzing soil vapour for a broad range of Volatile Organic Compounds (VOCs).

CARO has approached soil vapour with the objective of being industry technical leaders while improving soil vapour data quality and helping to reduce costs. Our team is technically knowledgeable and has practical field experience. Let us help guide your sampling protocols, quality planning and equipment requirements.  Contact us today!

CARO’s Vapour Accomplishments Include:

  1. Thermal Desorption (TD)

    We selected TD as the most cost effective, practical and technically sound approach for testing VOCs in soil vapour. We were pleased to introduce the new Vapor Intrusion (SVI™) TD Tube in 2009. Developed in partnership with PerkinElmer, this device has important performance benefits over other TD tubes. This approach is gaining widespread industry acceptance as the predominant soil vapour method.

  2. Industry Leading Detection Limits (DLs) and Instrumentation

    CARO was the first Western Canadian laboratory with TD “recollection” ability, allowing duplicates and dilution of high samples. Our industry leading DL ability enables reporting to much lower levels than previously possible (i.e. for risk assessment). Also, lower sample collection volumes are possible. In most cases, residential standards can be achieved with only 1L (or less) of sample. Read more here:

  3. CALA Accreditation

    CARO was the first Canadian laboratory to gain accreditation for soil vapour by TD (www.cala.ca)

  4. Regulatory Involvement:

    CARO authored the provincial BCMOE standard methods –  VOC by TD and VHv methods.
