The Fort Air Partnership (FAP) is a not-for-profit multi-stakeholder organization with members from industry, government, and the public. FAP operates an air quality monitoring network in an area northeast of Edmonton in and around Alberta’s Industrial Heartland, including the towns of Bon Accord, Bruderheim, Fort Saskatchewan, Gibbons, Lamont, and Redwater.

FAP currently operates a network of 57 passive monitoring sites within its air monitoring network. Passive air samplers are easy to deploy and operate, do not require electrical power, and are less expensive than continuous monitors. The FAP passive sites provide monthly average concentrations of hydrogen sulphide (H2S) and/or sulphur dioxide (SO2).

This report provides an evaluation summary and recommendations on the FAP passive monitoring network. The following summarizes the recommendations for the FAP passive network that resulted from this investigation:

  • Identify and document clear monitoring objectives for each passive site. Ensure that the substance monitored, the sampling interval, and the uncertainty associated with the collected data are appropriate for the objective.
  • Reduce SO2 and H2S monitoring in areas where sites have been identified as statistically similar.
  • Continue to co-locate passive monitoring with continuous monitoring stations for both H2S and SO2.
