Escherichia Coli As A Water Quality Indicator Organism: A Case For Responsive, Science-Based Policy, Sarah M. Mclarnan
Escherichia Coli As A Water Quality Indicator Organism: A Case For Responsive, Science-Based Policy, Sarah M. Mclarnan
All College Thesis Program, 2016-2019
Water quality indicator organisms such as E. coli are used in the monitoring of recreational waterbodies to indicate the presence of fecal contamination. In 2009, a 1.5-mile stretch of Plum Creek in Stearns County, MN was classified by the Minnesota Pollution Control Agency as impaired due to high levels of E. coli. Citizen science to investigate the source of this contamination began in 2014 and with the addition of student research from CSB/SJU in 2016. This thesis presents results of the 2016 study, supplemented by summary of Minnesota water quality policy and recent research on indicator organisms. The 2016 …

The Compass: Earth Science Journal of Sigma Gamma Epsilon
The major ions of Coal Creek near Cedar City, in southwest Utah, were measured to determine if there were any differences in ion concentrations in July of 2014 as compared with spring measurements of 2012 and 2013. Past analyses have shown higher ion concentrations in lower regions of Coal Creek despite the apparent lack of water input. This research is aimed to better characterize these abrupt increases in concentration and determine if these trends varied when samples were acquired in the summer vs. in the spring when sample acquisition has occurred in the past. Environmental water samples were collected at …
