Modeling taste and odor phytoplankton in Normandy Reservoir
The feasibility of modeling particular algae associated with taste and odors was investigated as part of an effort to develop a two-dimensional water quality model applicable to Normandy and Columbia Reservoirs (Duck River, Tennessee). There does not appear to be any dominant factor controlling the occurrence and abundance of taste and odor causing algae. A summary of dominant algal patterns observed in Normandy Reservoir is provided. A simplified algal model using a fully mixed surface volume (bag) was developed to explore the possibility of modeling several algae types simultaneously. The results of a field algal assay involving nutrient additions to bags of indigenous algae suspended in the Duck River at Columbia, Tennessee, were summarized and simulated using the algae model. Some of the observed algal responses were reproduced with the model, while others remain unexplained. The specification of growth characteristics for individual algal types is the limiting factor in this approach because these have not been well documented. Growth characteristics for dominant algal species must be determined for more accurate modeling of taste and odor potential in Normandy and Columbia Reservoirs. 21 references, 25 figures, 1 table.
