The VA Trout Stream Sensitivity Study (VTSSS), lead by scientists at the University of Virginia, is one of the most useful and fun things we do in TU. The purpose of the study is to track the level of pH in our streams. This is accomplished by periodic sampling of streams at designated sites. The first samplings were conducted more than 30 years ago, and TU volunteers and others have conducted followup samplings at the same sites every 10 years since. The last statewide sampling was in the spring of 2010.
