Abstract Some New Zealand regional councils are examining the use of faecal streptococci (or the subset, enterococci) to assist in identifying pollution sources, or as better indicators of disease risk in bathing waters than faecal coliforms. However, in spite of worldwide investigation, faecal streptococci have largely failed to fulfil their potential as pollution source (human versus animal) indicators in receiving waters. Many qualifications accompany the use of faecal coliform: faecal streptococci (FC: FS) ratios, and the species identification approach (using biochemical and DN A-based methods) has produced inconclusive results. Nevertheless, the FC : FS shift method (in which the ratio changes under sample storage) may
