Annual Public Open House
A chance to meet the community

For our Open House each year, we test hundreds of water samples from throughout Portland for just $1 each!
We also test other samples, such as plants, food, and soil. The analyses for these samples are not state-accredited to determine water or food safety, but are entertaining and educational.
To the right, one of our laboratory technicians disposes of old samples from the previous Open House.
