Soil Vapor Intrusion
SanAir’s Specialty Environmental division, formerly known as Centek Labs, has a national reputation for vapor intrusion testing, gained by working with New York State to develop and implement the NYSDOH Soil Vapor Intrusion Guidance beginning in 2003. To this day, the NYSDOH Vapor Intrusion Guidance is regarded as one of the most recognized documents relevant to Vapor Intrusion Sampling and Analysis.
Train derailments, leaking underground storage tanks, and leaching from improper disposal of industrial solvents, bring unfortunate but necessary attention to the threat that volatile organic compounds (VOCs) pose when released via soil intrusion and toxic plume.
SanAir’s analytical expertise and project management capabilities support a variety of soil vapor intrusion and indoor air investigations. We assist large conglomerates, government agencies, as well as smaller private firms and homeowners with their monitoring and remediation projects.
As a pioneer in the soil vapor intrusion industry, our focus has been on providing independent third-party testing that is cost-effective, enables nimble sampling in the field, and delivers stringent detection limit results down to the parts per trillion
We offer innovative Silonite™ coated summa technology using a wide variety of containers including Tedlar® bags, 400cc canisters, 1L canisters, 1.4L canisters, and 6L canisters. Equipment rentals are included in the cost of testing and can often be sent out to clients within one business day. Helium Leak Testing Soil Gas Tracer kits are also available upon request at no additional charge.
Our instrumentation can be modified by our technical staff according to your project’s needs to achieve low detection limits while maintaining the highest quality data for your vapor intrusion projects.
Health Impacts
VOC exposure can have wide-ranging health effects depending upon age, comorbidities, and other lifestyle factors. Immunocompromised individuals and fetuses may experience greater impacts, but anyone can experience damage to the central nervous system, kidneys, liver, lungs, and ultimately develop cancer.
Analytical Services
Volatile Organic Compounds (VOCs) in Air Collected in Specially Prepared Canisters and Analyzed by Gas Chromatography–Mass Spectrometry (GC-MS)
- EPA Method TO-15 — target compounds include chlorinated solvents (PCE, TCE and their breakdown products such as vinyl chloride, 1,1-DCE and others), benzene, toluene, ethylbenzene, xylenes, fuel aromatics, and fuel oxygenates
- Tentatively Identified Compounds (TIC) Analysis — more than 125,000 additional hazardous compounds within the air matrix
