Join Dr. Monica Arienzo of the Desert Research Institute (DRI) and myself for a fall River Walk on November 5th at 10:00 a.m. The event will be hosted by Keep Truckee Meadows Beautiful. We will walk along the beautiful Truckee River, talk about microplastics and their prevalence in the Truckee Meadows, and highlight some of the exciting microplastics research taking place at DRI and UNR. Be sure to sign up for the event before the slots fill up!
