“A lot of people have allergies and a lot of people like to know whether they take medication,” explains Hahn. “It’s just a nice thing to do for the community. And I think a lot of people appreciate it.” A pollen counting piece of machinery on the roof of Waterbury Hospital has been measuring pollen for 37 years. It collects a sample of the air every 10 minutes for 24 hours that the hematology lab examines each morning. Waterbury Hospital is home to the only pollen count center in New England that is certified by the American Academy of Allergy, Asthma, and Immunology. Reports on trees, grass, weeds, and mold can be found Monday through Friday on the hospital's website.
