Phosphorus And Metal Cycling In A Drinking Water Source, Amanda Modica
Phosphorus And Metal Cycling In A Drinking Water Source, Amanda Modica
Senior Theses and Projects
This project sought to investigate the cycling of phosphorus and metals in Lake Auburn, a drinking water source, specifically to analyze the impacts of an alum treatment on the lake for the purpose of decreasing concentrations of eutrophication-promoting phosphorus. The alum addition was performed in the summer of 2019 in two phases. Water samples were collected from the surface to the deepest point at five sites around the lake from February 2019 to November 2021. Data showed that the added alum slowly sank to the bottom of the lake. Total and dissolved metals data showed increased metals concentrations at sampling …
Geomorphological Approach To Toxic Trace Metal Distribution Across A Medial Bar Deposit In The Trout Brook Of The Park River Watershed, Hartford, Ct, Kelsey Semrod
Senior Theses and Projects
The Trout Brook, a major tributary of the Park River watershed, was sampled for heavy metals in sediment with a focus on Pb, Cu, Cd, and Zn. These metals are known to be contaminating the river due to a history of discharge from metal finishing industries. In a watershed-wide survey conducted in September 2011, high concentrations of metals were found in the Trout Brook, with some sites exceeding the probable effect concentration (PEC). The Trout Brook contains a Sanitary Sewer Overflow (SSO) and a vegetated medial bar that may be trapping sediment. Based on the results of the earlier studies, …
