Full Description

This paper discusses a tool under development to aid in source water protection that is called Microbial Source Tracking(MST). The concept of MST is that the origins of pollution can be traced usingmicrobiological, genotypic, phenotypic and/or chemical methods (Scott et al., 2002).MST can be used to provide the scientific basis for identifying microbial input sources tosource waters. Once a contaminant source is identified by MST methods, a utility candevelop and implement a targeted remediation strategy without spending money andeffort on "false" sources that may be indicated by land use analysis or sanitary surveysalone. Many MST tools involve molecular analyses; however, this study focused on toolswhich would be more easily and less expensively implemented by watershed managers.The objective of this study was to determine the utility of MST in discerning sources ofmicrobial contamination in a watershed. Includes 6 references, figures.
