| dc.description |
Wastewater treatment plants (WTP) input large amounts of effluent into coastal and estuarine waters. These effluents contain high concentrations of nutrients and microbes. These inputs can affect the ecology and sanitation of flora and fauna in the receiving waters. Increased nutrient concentrations, for example, can increase food (microalgae concentrations) and consequently growth for bivalves such as oysters, but can also render them inedible due to increased pathogen loads. Understanding these inputs and their impacts is critical to conserving and utilizing the natural resources in estuarine waters. This study was an examination of the effects of WTP-derived nutrients and bacterial and viral pathogens on oyster growth and survival and sanitation with increasing distance (dilution) from a major point source, the Clifton C. Williams WTP outfall in Mobile Bay, Alabama. This study additionally tested the efficacy of traditional (bacterial) and new (viral) indicators of wastewater influence on an important commercial shellfishery species. Since oyster growth, survival, and pathogen concentrations may vary with water temperature, we tested these effects seasonally. It was hypothesized that concentrations of nutrients (nitrate, nitrite, ammonia, and TDN) and microbial pathogens decreased with increasing distance from the outfall and nutrient and microbial concentrations impacted oyster ecology and sanitation. |
