Determining Stream Toxins with Water Quality and Level Data When researcher Wesley Gerrin gained access to a sediment toxicity lab in the Experimental Forest on the University of Georgia campus, he wanted to investigate an on-campus lake for any potential contamination issues. After his research was completed, he was fortunate enough to have some extra grant funding for the addition of a few samples from any location on campus, so he chose one of the most exciting sites on the University premises: Tanyard Branch. As Wesley said, “We ran the tests, and everything looked good, except for Tanyard Branch.” Tanyard Branch has been one of the most heavily monitored creeks in the Athens-Clarke County area for the last couple of decades due to contamination - it has a long history of abuse beginning in the 1700s.
