Many challenges exist in monitoring (drinking) water quality, particularly in resource-limited settings. Currently available microbial water tests often have a number of limitations within this context and require specific expertise. Tests are often cumbersome and while new technologies are emerging that promise to be cheaper, more user-friendly and faster, their efficacy and suitability for water quality testing needs to be reviewed.

Aim of the drinking water quality test decision tree

Various microbial tests are available, and choosing a suitable method for a particular application and setting is challenging. This decision tree provides guidance for the selection of appropriate monitoring parameters and choosing suitable tests for estimating these parameters.

How does the decision tree help you to select drinking water quality tests?

The decision tree supports the selection of microbial water quality tests for different purposes in safe drinking water production. The decision tree guides the user in three steps to a list of fit-for-purposes microbial water quality tests.
