Full Description

This article examines a "toolbox" approach foridentifying pollution sources, especially fecalsources, within a watershed. Distinguishing humanand animal sources is important in assessing humanhealth risks. Traditional water quality measurementscannot conclusively differentiate fecal sources, thusmicrobial source tracking (MST) is necessary toidentify contributions from different sources.In this study, a toolbox approach that includesboth traditional indicators and multiple MST targetswas used to demonstrate what measures are neededin a toolbox and how to best use these measures toobtain useful data.The authors found that several physical and chemicalwater quality measures were redundant and couldbe eliminated from a sampling plan. Their toolboxapproach integrates monitoring techniques that can betailored to meet the needs of individual watershedmanagement agencies, even those with limitedresources. The MST targets in the toolbox can incorporatewith bacteriological facilities already available tomost watershed management agencies. Includes 54 references, tables, figure.
