Analysis, Identification, and Strategies for Urban Wildlife Contamination to Support TMDL Implementation (Washtenaw County, Michigan)

Data for this project was originally collected in 2  3.  But the   final portion of this project went from the spring of 2  5 to the   fall of 2  5.  Data from the 2  3 and 2  5 projects were compared.    This project applied library-based genotypic bacteria source  tracking (BST) technology within the municipal storm sewer system   (MS4) to identify and quantify species-specific sources of E. coli.   The project goals were addressed through the collection and analysis   of samples of storm water from two locations in the MS4 and  reference material (scat) from various species known to be present   near those locations.    The sampling from this project generated both quantitative and   bacteria source tracking analytical results. The quantitative data   from the storm sewer sampling include the following observations:  - Results were comparable to previous data collected in Fall 2  3;  - Spring concentrations tended to be lower than fall concentrations;   and,  - Seasonal wet weather concentrations were higher than dry weather   (as  expected).    The BST data and source analysis yielded the following observations:  - The predominant fecal sources are pets and raccoons;  - Among pets, cats usually accounted for a larger proportion than   dogs;  - Birds are not a major source at either site;  - The Sheridan site had sporadic high measurements of human fecal  contamination, indicating it may still have an illicit connection,   despite IDEP work done in 2  3;   - Some storm sewer sequences, particularly at the Sheridan site,   could not be matched to a source in the reference database,   suggesting that there may be 4 additional sources not accounted for   (such as rats, deer) or that occur rarely in the sources considered   for this project.    (microbial source tracking); (MST); (bacterial source tracking);   (BST); (Michigan); (Washtenaw county)
