Air Testing Services

Torrent Laboratory is an accredited air quality testing laboratory serving environmental consultants, industrial hygienists, remediation teams, and property managers across the Bay Area and beyond. Air analysis has been run in-house at the Milpitas, California facility for more than 30 years, not sent out to a subcontractor, so the chemists reviewing your data are the same people who ran the instruments that generated it.

Torrent holds CA ELAP, ISO/IEC 17025:2017, DoD ELAP, DOECAP-AP, and Alaska DEC CS-LAP accreditations covering air testing methods. The laboratory supports indoor air, ambient air, workplace exposure, vapor intrusion, stack, and emissions-related projects using established EPA, ASTM, and NIOSH methods.

Torrent supports air quality testing services for environmental, occupational, regulatory, and real estate projects. Air quality testing is available for the following project needs.

Ambient Air Testing

Analysis for outdoor air, site perimeter monitoring, source evaluation, and background condition assessments.

Indoor Air Quality Testing

Testing for VOCs, formaldehyde, metals, particulates, asbestos fibers, and other contaminants that may affect occupants inside a building.

Air Quality Monitoring Support

Support for ongoing, periodic, baseline, event-based, and long-term sampling programs used to track air quality trends.

Stack and Emissions Sample Analysis

Laboratory analysis for industrial facilities, process streams, combustion sources, and regulatory compliance projects.

Soil Vapor and Vapor Intrusion Analysis

Testing for vapor intrusion projects where subsurface vapors may affect indoor air or buildings, including Soil Vapor Testing.

Occupational and Workplace Air Sampling Analysis

Analysis for industrial hygiene, employee exposure, and workplace safety assessments.

Asbestos Fiber Counting by NIOSH 7400

Airborne fiber counting for abatement clearance and asbestos monitoring projects.

Indoor air quality testing provides the laboratory data needed to evaluate airborne contaminants inside buildings and support decisions for occupant safety, property management, workplace exposure, and environmental investigations.

Building and Source Evaluation

Indoor air testing helps identify contaminants that may be associated with building materials, occupant activities, water damage, renovation work, vapor intrusion, industrial operations, or outdoor sources.

Properties Served

Torrent provides indoor air quality testing for commercial buildings, schools, healthcare facilities, residences, industrial sites, and mixed-use properties.

Contaminants Analyzed

Testing may include VOCs, formaldehyde, metals, particulates, asbestos fibers, diesel particulates, sulfur compounds, and other contaminants of concern.

Common Project Needs

Indoor air testing is often used for new construction, off-gassing, water damage, renovation dust, odor complaints, occupant concerns, tenant disputes, real estate transactions, workplace exposure reviews, and vapor intrusion investigations.

Supported Methods

Torrent supports EPA TO-15, EPA TO-15 SIM, EPA TO-17, EPA TO-11, NIOSH 7303, NIOSH 1550, and NIOSH 7400 for project-appropriate indoor air analysis.

Client Support

Torrent provides laboratory analysis, sampling media, chain of custody documentation, technical consultation, and referrals to qualified field sampling professionals when on-site collection is required.

Air quality monitoring usually means more than one sample. Remediation sites, construction projects, and industrial facilities often need repeated rounds of sampling to track trends, confirm perimeter conditions, or compare results against a baseline. Torrent works as the analytical lab behind that kind of program rather than as a field monitoring contractor.

For multi-round projects, consistent reporting is what makes the data usable. Torrent can supply standardized report formats and electronic data deliverables, and clients running recurring events can arrange standing supplies of certified-clean Summa canisters, flow controllers, and sorbent tubes ahead of time.

 Projects with more complex reporting needs can work with the team through custom reporting.

Torrent helps clients match the right analytical method to the contaminant of concern so the data is appropriate for indoor air, ambient air, workplace exposure, vapor intrusion, stack, or emissions-related decisions.

Contaminant Range

Air quality testing identifies a wide range of contaminants depending on the project setting, sampling method, and regulatory or risk-based objective.

Method Matching

Torrent helps clients match the right analytical method to the contaminant of concern and project requirements.

Project Applications

Results support indoor air, ambient air, workplace exposure, vapor intrusion, stack, and emissions-related decisions.

Volatile Organic Compounds (VOCs)

VOCs can come from solvents, fuels, paints, coatings, building materials, industrial processes, and vapor intrusion. Torrent supports EPA TO-15, TO-15 SIM, and TO-17 for VOC analysis.

Petroleum Particulates

Petroleum particulates may come from diesel engines, fuel handling, combustion, transportation, and industrial operations. Torrent supports NIOSH 1550 for workplace exposure and related investigations.

Polynuclear Aromatic Hydrocarbons (PAHs)

PAHs may be associated with combustion, vehicle emissions, industrial processes, and petroleum-related sources. Torrent supports EPA TO-13 for air analysis where PAHs are a concern.

Pesticides

Pesticides in air may be associated with agricultural applications, pesticide use, and applicator activities. Torrent supports EPA TO-10 for occupational, environmental, and exposure investigations.

Metals

Metals in air may come from welding, plating, manufacturing, demolition, and other industrial activities. Torrent supports NIOSH 7303 for workplace and industrial air monitoring.

Formaldehyde

Formaldehyde may be associated with building materials, furnishings, manufacturing, and new construction or renovation. Torrent supports EPA TO-11 for indoor air quality and off-gassing assessments.

Sulfur Compounds

Sulfur compounds may be associated with landfill gas, biogas, industrial processes, and combustion sources. Torrent supports ASTM D5504M for odor, emissions, and process-related investigations.

Method selection depends on the contaminant, sampling media, detection limits, and what the data needs to support.

Torrent’s methods are consistent with EPA’s published TO-15A method documentation for canister-based VOC analysis. Contact the lab before sampling if a project needs a specific turnaround time.

Good air data starts before the sample reaches the lab. Torrent supplies certified-clean Summa canisters and flow controllers through the canister order form, along with sorbent tubes and other sampling media through Supplies & Media.

Torrent also supports projects with chain of custody documentation, project management, and technical consultation to help clients prepare before collection begins. Torrent Express pickup can help coordinate sample and supply logistics where available.

For projects requiring consistent data delivery, Torrent provides electronic data deliverables and custom reporting to support recurring monitoring programs and project-specific reporting requirements.

Torrent Laboratory’s accreditation and quality systems provide a strong foundation for defensible air testing data. Rather than relying on broad claims alone, Torrent maintains recognized accreditations that support environmental, government, industrial, and high-sensitivity project requirements.

Torrent maintains the following recognized accreditations.

• California ELAP, Certificate #1991
• ISO/IEC 17025:2017 Quality Management System
• DoD ELAP, QSM 6.0
• DOECAP-AP, QSM 6.0
• Alaska DEC CS-LAP #24-001

Torrent’s air testing services are designed for clients who need reliable laboratory data, responsive project support, and defensible reporting. 

Torrent supports the following clients and project teams.

• Environmental consultants
• Engineering and remediation firms
• Industrial hygienists

For indoor air, vapor intrusion, monitoring, or workplace exposure projects, Torrent helps clients select the right analytical path and receive decision-ready data.

Torrent runs air testing from its Milpitas laboratory at 1652 Watson Court, Milpitas, CA 95035, serving the Bay Area (San Jose, Milpitas, Fremont, Oakland, San Francisco), Northern and Southern California, Hawaii, Alaska, and Guam.

Clients outside the immediate Bay Area can contact the lab to coordinate shipping and sampling media ahead of time.

Air testing is often part of a broader environmental investigation. Torrent provides complementary laboratory services for projects involving vapor intrusion, water quality, stormwater, emerging contaminants, hazardous materials, and site characterization.
