Petroleum Hydrocarbons (PHC) are one of the most common forms of environmental contamination - posing significant human health risk.
Petroleum Hydrocarbons (PHC) are one of the most common forms of environmental contamination in North America - posing significant human health risk. Many regulatory jurisdictions (federal, state & provincial) are not only interested in testing for individual PHC, but also for total petroleum fractions and sub-fractions.
ALS locations hold accreditations and certifications relevant to their work and area of operation. Participation in NELAP, CALA, AIHA-LAP, DOD, various state and other programs is location - specific. Refer to Scopes of Accreditation in the Downloads section of this site for details relevant to each ALS location.
Many regulators nationwide (e.g. Massachusetts DEP, CCME Canada-Wide Standards) utilize a “fractionated TPH” approach to evaluating soil and groundwater contamination. The Air-Phase Petroleum Hydrocarbon (APH) method is the appropriate complementary air-phase analysis for sites where vapor intrusion is a concern.
Different total hydrocarbon ranges or aliphatic/aromatic sub-fraction ranges can have significantly varied human health-based toxicological effects. Our services support clients in meeting regulatory air standards for soil vapor migration that can impact indoor air quality through infiltration of sub slab soil vapor into basements and living spaces.
ALS air quality laboratories across North America have the methodology and equipment necessary to meet all your petroleum hydrocarbon testing needs.
- Methods based on EPA TO-15 and TO-17, MassDEP APH, NMAM 1550, Atlantic RBCA, and CCME-CWS
- Applicable PHC include: gasoline, fuel oil, jet fuel, mineral spirits, and other volatile mixtures
- An inventory of over 5,000 canisters (available as batch and individually certified)
- Time integrated critical orifice and calibrated flow controller sampling equipment
