Presence Of Glyphosate In First Order Streams Associated With Rainfall Events, Julie Platz

Undergraduate Honors Thesis Projects

Glyphosate is widely used in the United States and has recently been described as both mobile and persistent in soils and bodies of water. There is little research however, on the variability of glyphosate concentration in runoff based on different land use types. For this study an evaluation of samples from different land uses are used to assess glyphosate concentrations in first order streams during a runoff event. The intent was to compare three sites with a. known commercial applications, b. known lack of applications (organic), and c. assumed limited application of glyphosate. There was no significant difference in glyphosate …

Recovery Potential Of The Mussel Communities In The Lower Section Of Big Walnut Creek, Jared B. Ellenbogen

Undergraduate Honors Thesis Projects

Since the enactment of the 1977 Clean Water Act, biologists have created numerous multimetric assessment tools to evaluate the biological integrity of water resources, using biological criteria. The integrity of Big Walnut Creek, Ohio, has been in flux since the 1955 construction of Hoover Dam, and while current water quality is high, mussel communities in the creek have yet to recover to historical levels. This study sought to determine the cause of the decline in the mussels in the lower section of the creek below the dam. Historical creek data, including a fish-based index of biotic integrity (f-IBI), invertebrate community …
