INDOOR AIR QUALITY MONITORING – AEROSOL PARTICLE COUNTER USED IN MOLD INVESTIGATION AT LOCAL SCHOOL

Poor indoor air quality in our educational facilities is an ongoing concern in many communities. Mold in particular, has teachers, students, parents, and administrators across the country looking very closely at possible causes of contamination, and the associated costs of dealing with these problems. A growing number of professionals conducting IAQ investigations are utilizing a wide variety of testing instrumentation, including aerosol particle counters, to aid in better defining these contamination sources. I recently spent time assisting with an IAQ investigation at a middle school (Grades 6-8) in Southern Oregon, and will share the testing methodology and results in this article.
