Indoor Air Quality

The types of industries/processes for which we have provided indoor air quality assessment services include telecommunications, textiles, rubber compounding, stone products, brownfields facilities and the U.S. Forest Service.  Our assessment experience includes collection of indoor air samples for laboratory analyses of volatile and semi-volatile organic compounds, oil mist, particulate matter using SUMMA® canisters and portable sample pumps with compound-specific sample tubes and cassettes, and evaluation of the results with OSHA Permissible Exposure Levels for worker safety and EPA Screening Levels for Brownfields redevelopment.  We have also conducted inspections of laboratory fume hoods to determine compliance with Section 3, “Laboratory Chemical Hoods” of the audit checklist of the American National Standards Institute/American Industrial Hygiene Association (ANSI/AIHA) Standard Z9.5.

Our staff has experience in conducting indoor air quality assessments for evaluation of HVAC systems in accordance with OSHA (29 CFR 1910) and Standard 62 of the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) standards as part of Brownfields redevelopment.  We perform vapor-intrusion assessments and design active and passive remediation systems on sites contaminated with chlorinated and petroleum compounds. Vapor-intrusion assessments are performed using SUMMA® canisters, the SIM Method, vapor wells and compound-specific sample-tube collection.
