“…To prevent illnesses, thousands of hectares of fishing areas in the USA are closed to shellfish harvest due to elevated concentrations of fecal indicator bacteria and other criteria that may not be reflected by fecal coliform indicators (Rippey 1994;Glasoe and Christy 2005). The resulting economic impact from lost fishery yield is considerable (Alexander 1998;Landrum and Ache 2000). Hence, there is substantial need for better detection and identification of wastewater influences on coastal systems to inform fisheries management and protect public health (e.g., Randall 2003;Savage 2005).…”

We measured seasonal effects of wastewater treatment plant (WTP) effluent on growth, survival, and accumulation of microbes in oysters near a major WTP in Mobile Bay, AL. Despite higher nutrients near the WTP, seasonal conditions rather than distance affected chlorophyll a concentration and oyster growth. In summer and fall, when oyster growth was higher, δ 15 N‰ in oysters near the WTP changed through time to reflect δ 15 N‰ in effluent (approx. −4‰). Microbial indicators (male-specific coliphage, fecal coliforms) were highest in oysters near the WTP in all seasons and correlated with δ 15 N‰ in fall and summer. Increased riverine discharge and slower acquisition of δ 15 N‰ likely confounded correlations in winter/spring. Although we did not detect gross ecological effects of wastewater exposure for oysters, data indicated wastewaterderived particles entered the local food web and accumulated in oysters. These data highlight the importance of using multiple indicators of wastewater exposure and considering both seasonal and spatial effects when defining wastewater influence on a system or species.
