A New Qpcr Assay To Detect Geosmin-Producing Cyanobacteria, Shane Brian Davis
A New Qpcr Assay To Detect Geosmin-Producing Cyanobacteria, Shane Brian Davis
Theses and Dissertations
Taste-and-odor (T&O) compounds are frequently produced by cyanobacterial blooms in bodies of water. Geosmin, perhaps the most common T&O compound produced by these blooms, is not effectively removed by conventional water treatment processes and frequently causes the tap water to have an off flavor. Although geosmin is not harmful when ingested, it damages the consumers' confidence in the cleanliness of their water. There are treatment options for geosmin removal, but the most common methods are often not implemented until complaints are made by consumers.There has been an increasing amount of research on the use of polymerase chain reaction (PCR)-based methods …
Improved Land Use And Land Cover Classification And Determination Of The Influence Of Land Use And Land Cover On The Water Quality In An Agriculture Dominated Watershed, Scott Landon Sanders
Improved Land Use And Land Cover Classification And Determination Of The Influence Of Land Use And Land Cover On The Water Quality In An Agriculture Dominated Watershed, Scott Landon Sanders
Theses and Dissertations
Classification of remotely sensed imagery for reliable land use and land cover (LULC) change information remains a challenge in areas where spectrally similar LULC features occur. Dissolved organic matter (DOM) influences the biogeochemistry of aquatic environments and its quantity and quality are due, in large part, to the surrounding LULC. Thus, objectives were to improve the accuracy of LULC classification and quantify seasonal variations of water quality in a watershed dominated by agriculture and determine the controls for the variations in water quality. Support vector machine classification scheme with post classification correction yielded highest accuracy for LULC classifications and four …
