We have published a COVID-19 bulletin about back to work air sampling.  Information includes reasons why air sampling in the building, before employees return, is a good idea.  Additionally, we cover ways that we can sample inside buildings, even if they are occupied.

We have published a description of ambient air monitoring and industrial hygiene work that we are performing at a wastewater treatment facility undergoing expansion.  Real-time and integrative sampling is being performed ensuring safe conditions for workers and the general surrounding population.
