Other Testing or Sampling: Did EPA sample for black carbon?

Return to: Frequently Asked Questions

Black carbon (soot) is part of PM 2.5 (particulate matter smaller than 2.5 microns), which is measured in air monitoring. Since the fire, we have not seen levels of PM2.5 that would be of concern to the community’s health.
