A recent study by Murei, et al. (2024) titled “Selection of a diagnostic tool for microbial water quality monitoring and management of faecal contamination of water sources in rural communities” published in Science of the Total Environment, shows that the hydrogen sulphide (H2S) test and sanitary inspections are cost-effective and suitable tools for monitoring faecal contamination in rural areas at the household level.

Hydrogen sulphide tests and sanitary inspections are cost-effective tools for monitoring faecal contamination in rural water sources.– Murei, et al. 2024
The article, titled “Selection of a Diagnostic Tool for Microbial Water Quality Monitoring and Management of Faecal Contamination of Water Sources in Rural Communities,” focuses on assessing and selecting effective tools for microbial water quality monitoring in rural settings. Conducted by researchers from Tshwane University of Technology and the University of South Africa, the study explores various methods to monitor water quality at multiple levels. These include sanitary inspections, hydrogen sulphide (H₂S) tests, the enumeration of faecal indicator bacteria, and advanced molecular techniques like qPCR for detecting host-associated genetic markers and pathogens.
How the Study was Conducted
The study employed a multi-faceted methodology. Authors from the Tshwane University of Technology and the University of South Africa conducted a comprehensive evaluation of various microbial water quality monitoring tools. The authors utilized methods such as sanitary inspections, hydrogen sulphide (H2S) tests, enumeration of faecal indicator bacteria, and advanced molecular techniques like qPCR for detecting host-associated genetic markers and pathogens. This approach allowed the authors to assess the effectiveness and suitability of different tools for monitoring faecal contamination in rural areas at the household level.
