Abstract

In this study three different Microbial Source Tracking methods (MST) have been evaluated in laboratory experiments with the objective of determining which is more effective and reliable in distinguishing between human and animal sources of fecal contamination in groundwater. A preliminary literature review of all the MST methods applicable for surface and ground water has been done, and the use of microbiological indicators has been selected. The methods selected involved the enumeration of Fecal Coliforms (FC), Fecal Streptococci (FS), Clostridium perfringens (CP) and Human Bifidobacteria (SFB), parameters which are generally defined as Bacterial Indicators (BI). The first method consisted of calculating the FC/FS ratio, the values of which can be related to animal or human sources, while the second method consisted of the enumeration of CP, which in some studies was associated with animal sources of fecal pollution. Finally, the third method enumerated levels of SFB, which are associated exclusively with human sources of fecal pollution. (Abstract shortened by UMI.)Dept. of Civil and Environmental Engineering.
