Over the past 15 years, microbial source tracking (MST) methods have emerged as a management tool for water quality authorities to identify the sources of faecal contamination in receiving waters. The majority of the MST methods require the development of a library of target strains or faecal indicator bacteria from suspected sources by using various genotypic or phenotypic methods. Phenotypic or genotypic patterns of target strains are then compared to the library to identify their likely sources. None of these library-dependent methods are regarded as a 'gold standard'. Significant limitations include the size and representativeness of the developed library, temporal and geographical stability of target strains, host specificity of target strains, relative persistence of target strains in receiving waters and differences in statistical methods used. This paper reviews the various assumptions and limitation of library dependent methods currently used for source tracking.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
