P056: Potential for Pathogen Growth, Fecal Indicator Growth and Phosphorus Release under Clam Removal Barriers in the LTB

Using microcosm laboratory experiments that mimicked winter and summer-like conditions under the rubber barriers, this project examined: -Whether fecal indicator bacteria such as total coliforms, fecal coliforms, Escherichia coli and enterococci re-grow under the barrier. -Whether artificially added human pathogens (Campylobacter jejuni and Salmonella enterica) re-grow and/or persist. -Whether alternative fecal indicator bacteria such as universal-, human-, dog- and bovine-associated Bacteroidales re-grow. -The amount of ammonium, phosphate and dissolved organic carbon released under the barrier as a result of decaying Asian clams.
