This framework of tools is used to identify the source of pollutants in a waterway that has become contaminated with faeces.
The framework of tools has been developed and used by the Institute of Environmental Science and Research New Zealand (ESR). The framework was developed to address the need to identify the source of faecal contaminants in waterways with high E. coli levels. The need to identify source of contaminants arose from a management and mitigation perspective allowing a focus to be placed on the clean-up of those waterways by directly reducing the source of such waste.
The ESR framework uses a range of methods to identify the source of faecal contaminants;
Decision analysis trees are provided for suspected human faecal pollution, animal/bird faecal pollution, or mixed source faecal polllution
Example of Decision Analysis Tree - Detection of human faecal pollution
The results from the methods outlined can be used to identify the species that was likely the cause of the faecal contaminant of the study waterway. This information can then be used to direct and inform management strategies and budgeting to contain or reduce the source of faecal inputs into waterways at the source rather that excess spending in an undirected mitigation approach.
