Recreational waters are monitored for fecal indicator contamination as a proxy for infectious organisms that may be present. Tests often look for fecal coliforms or E. coli, which indicate that mammalian feces is present in the sample. Bacteroides sp. are often used to identify the specific animal origins of the fecal material, as different Bacteroides are specific to different host animals. The HF183 Bacteroides marker occurs in high densities in human guts and is abundant in wastewater and specific for human waste.

This study looks at fecal markers in surface water contaminated with human wastewater and utilizes a magnetic Nanotrap® Particle for capture and concentration of microbes in these samples for fast and reliable detection. This method is compared to a standard filtration method to determine relative sensitivity.
