Microbial Source Tracking in Two Southern Maine Watersheds

This Microbial Source Tracking Project investigated non-point source   pollution in the Webhannet Estuary and Little River Estuary   watersheds in Wells, Sanford and Kennebunk, Maine. This project   focused on the Webhannet watershed the first year (Dec. 2  1-Sept.   2  2), and the Little River watershed the second year (Dec. 2  2-  Sept. 2  3).    The goal of the project is two-fold. First, to help validate genetic   fingerprinting (ribotyping) of E. coli as a method for identifying   the source of fecal contamination in surface waters. The second goal   is to determine the source animal species of the fecal contamination   in the Webhannet and Little Rivers in York County, Maine. Fecal   indicator bacteria such as E. coli are used to assess the possible   presence of disease-causing agents in water. Similar bacteria are   used to determine whether or not to close shellfish beds.   Understanding the sources of these bacteria would represent a   significant advance in water quality assessment. It could also help   continue a trend toward cleaner estuaries, eventually helping to re-  open portions of the estuaries to shellfishing.    (microbial source tracking); (MST); (bacterial source tracking);   (BST)
