    Microbial Source Tracking in the Manasquan River Estuary: Research Project Summary
    (Trenton, N.J. : New Jersey Department of Environmental Protection, Division of Science, Research and Technology, 2005-06) Palladino, Michael A.; Tiedemann, John A.; Atherholt, Thomas B.
    Multiple Antibiotic Resistance (MAR) analysis, one of several new tests developed within the past decade, was used in an attempt to identify the sources of fecal pollution in the Manasquan River estuary. The estuary is vital for recreational activities and as a shellfish resource. The test identifies fecal-derived, human- and animalspecific Escherichia coli (E. coli) bacteria through host-influenced differences in antibiotic resistance. The estuary contains multiple sources of fecal pollution. At many sites there appears to be an abundance of inputs from wild animals. This is an ongoing study. The work to date is best viewed as a “pilot project,” providing a tool to begin to identify sources of E. coli in the estuary. Due to the current limitations of the MAR technology and the lack of unambiguous source apportionment at most sites, the best use of the data may be to rule out potential sources of pollution.
