Water Quality Testing at Hart and Knez Wetland

Join TWC for some basic chemical testing along the banks of our Tigard Wetlands. We’ll set up a picnic blanket at the waterline and use mobile chemistry sets to test for dissolved oxygen, phosphates, nitrates, and pH levels while the songbirds and dragonflies swoop overhead. This small community event requires no experience, no trekking through mud, and no boots, just a lot of patience and a steady hand! TWC will provide all personal protective equipment, but participants must drive themselves between sites. Thursday, June 12th from 9:30-12pm. Space is extremely limited! Click here to RSVP.
