Book Workshop on Microbial Source Tracking in Water

Download or read book Workshop on Microbial Source Tracking in Water written by Paul A. Rochelle and published by IWA Publishing. This book was released on 2006-07-31 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The drinking water and wastewater industries are interested in developing a better understanding of sources of fecal contamination. Microbial source tracking (MST) offers the potential to apportion the contribution of various animal groups to this contamination. However, while there are many methods available there is no clear indication as to the most appropriate approach. There has been little systematic comparison of methods and only a few blind trials, and issues of reproducibility, accuracy, sensitivity, specificity, resolution, and robustness need to be addressed. There is confusion among potential end-users and some disagreement among scientists. Therefore, due to the uncertainty surrounding the most appropriate tools and applications of MST, a workshop of 45 experts representing water and wastewater utilities, academia, state and federal government agencies, medical institutions, and private laboratories was convened in San Antonio, Texas over a three-day period (February 16 – 18, 2005). The overall objective of the workshop was to identify the knowledge gaps and research needs for application of MST technologies by the wastewater and drinking water industries.

Van Asch and published by . This book was released on 2009 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial source tracking (MST) is a general term given to any process which aims to determine the source of microbial contamination found in an environmental (usually water) sample. These methods include both phenotypic and genotypic strategies. In this study, quantitative PCR was used to evaluate water samples for species specific (cow and human) Bacteroides in the Finley River. The Finley River is susceptible to impacts from both bovine and humans as it flows through farmland and urban areas. Water samples were collected from sites identified in a previous study that had high E. coli levels. Two samples were collected at each site (One sample for enumeration of E. coli and the other to assay for Bacteroides). Sampling was done approximately three times per month for one year. For each sampling event, pH, DO, turbidity, water temperature, flow rate, and rainfall were recorded. The results showed lower than expected cow markers throughout the sampling period; while human markers were much more prevalent than cow markers during the drier (and warmer) months. A correlation was found between human specific Bacteroides markers and E. coli at one site, but not at either of the other two sites. This method affords more informative surveillance data to area health departments so more appropriate remediation strategies can be developed.

Book Understanding Contributions of Fecal Bacteria Sources in Wyoming Rivers to Inform Pollution Management

Download or read book Understanding Contributions of Fecal Bacteria Sources in Wyoming Rivers to Inform Pollution Management written by Kelsey C. Ruehling and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pathogen contamination is the leading cause of impairment in American rivers. Most water quality monitoring programs use fecal indicator bacteria (FIB) like Escherichia coli, as a proxy for fecal pollution and dangerous enteric pathogens. However, standard FIB enumeration methods are unable to differentiate pollution sources, limiting resource managers ability to implement targeted management actions. Uncertainty about source contributions can be overcome with new molecular and genetic techniques like microbial source tracking (MST). We employed community-based microbial source tracking using high-throughput sequencing (HTS, 16S amplicon sequencing) of aquatic and fecal samples to understand fecal source contributions to surface water microbial communities in two watersheds in Wyoming, USA. While watershed-differences led to some variation of fecal pollution and aquatic microbial communities between the two watersheds, common patterns and drivers emerged. Both watersheds had higher bacterial diversity, and distinct bacterial assemblages in headwater streams while further downstream locations with legacy anthropogenic alterations had less diverse and more similar bacterial communities. We found that higher microbial diversity and increased fecal bacterial loading were related to changes in stream hydrology, and were most pronounced during periods of high runoff from snowmelt. We found no relationship between fecal bacterial sources from MST and standard E. coli enumeration, indicating E. coli may not be a good proxy for fecal pollution in these systems. This research will inform mitigation plans that resource managers are currently developing by providing novel insights about fecal bacterial sources for Wyoming streams that were recently listed as impaired.
