Simple Home Water Tests Lead to Safer Drinking Water and Behavior Change

Co-author Dr Zahra Murad, Associate Professor from the University of Portsmouth in England, highlighted the power of information in prompting behavior change. Knowing that their water is unsafe motivates people to take action to protect their families. This change can begin with a simple water test.

The study revealed that such interventions could save lives at a lower cost compared to many other public health programs, especially in low-income settings. The research followed a method recommended by the World Health Organization and World Bank data.

In many cases, the cost-effective approach of testing water and providing basic advice proved more beneficial than other health programs in impoverished regions. This is crucial where access to clean water is limited, and people may not be aware of the risks associated with their drinking water.

Dr Murad emphasized that people respond to timely, specific, and credible information, rather than incentives or equipment, to take action. The findings support the use of context-specific and individually targeted behavioral interventions to bolster public health efforts in developing countries.

The researchers recommend further studies over an extended period and in diverse locations to validate the results observed just months after the initial intervention.

Lead author Dr Muhammad Khan from COMSATS University Islamabad, Pakistan, noted that a simple water test and informational leaflet can significantly improve safe water practices, paving the way for scalable community health initiatives. Policy makers can incorporate water testing and tailored messaging into existing clean water infrastructure investments and community health programs to maximize benefits with minimal resources.

The study was a collaborative effort involving COMSATS University Islamabad in Pakistan, the University of Portsmouth in England, and the Leeds University Business School in England.
