Ambient Air Monitoring

Sidebar Image

Ambient air monitoring programs are initiated to monitor exposure of a community to chemicals released as a result of:

  • Remediation activities
  • Nearby industrial processes
  • Natural or man-made environmental disasters. 

Examples of remediation projects include the clean-up of former manufactured gas plant (MGP) sites in which perimeter air monitoring is required to measure chemicals released during soil of excavation and removal. The chemicals of concern are primarily BTEX and Polycyclic Aromatic Hydrocarbons (PAHs) as well as Particulate Matter (PM). During the course of the remediation project, air monitoring is required continuously, generating a large number of EPA TO-15, TO-13A, and PM10 filter samples. Eurofins Air Toxics maintains a large media inventory to consistently supply the field team with required equipment.  Each canister and flow controller goes through multiple quality checks to insure the media is properly functioning before leaving the laboratory. Our operational capacity and quality systems insure that the project objectives are consistently met throughout the entire program.

Active landfill facilities and industries such as petroleum refineries may have ambient air monitoring requirements from the local or state agencies. Eurofins Air Toxics provides TO-15 analysis to meet the specific compound list and reporting limits required for these programs. Specific to the petroleum industry, Eurofins Air Toxics has developed a TO-15 product designed to measure nearly 170 calibrated VOC from Ethylene to Undecane with reporting limits typically less than 0.5 ppbv. 

In addition to ambient air monitoring programs, the EPA has proposed fence-line air monitoring rules for petroleum refineries using passive sorbent samplers to measure Benzene concentrations over a 14-day period following EPA Method 325. Eurofins Air Toxics has supported this method over the past several years, participating in the EPA round-robin evaluation of the method. Our laboratory has a large inventory of sorbent tubes and operational capacity to support EPA 325 as well as extensive practical and technical experience with passive sorbent methods. 

Natural or man-made environmental disasters such as forest fires, train derailments, or oil spills may require emergency response to assess chemical exposures to nearby communities or clean-up crews. Eurofins Air Toxics can effectively respond to these emergency ambient monitoring situations with a ready supply of sampling media, highly technical staff to quickly identify the most suitable sampling and analytical methods, and the capacity to quickly analyze and report unplanned samples, allowing for quick decisions regarding health and potential chemical exposure at the site.
