Abstract:
The perceived safety of tap water is an important condition for consumers to drink it. Therefore, addressing consumers' concerns should be included in the roadmap towards the UN SDG 6 on safe drinking water for all. This paper studies consumers' information needs regarding emerging contaminants in drinking water using a mental model approach for the development of targeted risk communication. As most consumers expect safe drinking water, free of contamination, communication on emerging contaminants may increase concerns. Here, we showed that communication strategies better tailored to consumers' information needs result in smaller increases in risk perception compared with existing strategies.
