Abstract:

The City of Plattsburgh has a municipal beach within the Cumberland Bay of Lake Champlain as well as other public access points. The beach and the lake are a principal economic and recreational driver for the City and the region. Similar to other beaches in New York, Vermont, and Quebec, the Plattsburgh City Beach has recently experienced uncharacteristically high levels of fecal indicating bacteria (FIB) that have resulted in beach closures. Intensive monitoring and investigation in 2015 and 2016 identified potential sources of FIB within Cumberland Bay and contributing watersheds.

This investigation attempted to link previous spatial and temporal patterns of elevated FIB (fecal coliform, E. coli, and/or enterococcus) to specific host sources using Microbial Source Tracking (MST) methodologies. Samples were collected during 18 sampling events between May and September 2017, from eight locations, and encompassed dry and wet weather conditions, as well as post-combined sewer overflow (CSO) events. All samples were analysed for Total Coliform and Fecal Coliform enumeration by Method SM 9223 Quantitray, E. coli enumeration by Method SM 9223B Colilert, Enterococci enumeration by Enterolert, and membrane filtration/archiving.how to write a citation
