The Dutch chain approach on pharmaceuticals in water: Stakeholders acting together to reduce the environmental impact of pharmaceuticals

AIMS: Sewage treatment effluent with pharmaceutical residues is discharged into surface waters, raising societal concerns. The aim of this paper is to describe the Dutch chain approach on medicinal residues in water that has been implemented by the Dutch government. We show how stakeholders from both the health and water sectors have got actively involved. Within this chain approach, source measures as well as end‐of‐pipe measures are identified and, where feasible and effective, implemented. METHODS: Descriptive paper on the Dutch chain approach. RESULTS: Getting the water and health care sectors to talk with each other instead of about each other was the key accomplishment. Comprehension of each other's viewpoints, terminology, policy goals and span of control, was pivotal in setting shared goals, creating perspective about possible measures and actually taking (joint) action. Together, stakeholders agreed to act within their own possibilities, without pointing at others, and to focus on pragmatic measures. In this article, we provide examples of measures taken, pilot projects performed, and of measures that were not implemented. Besides this, we discuss the most important barriers encountered during this process and how they were overcome. CONCLUSION: The issue of pharmaceuticals in the environment is a wicked problem, which makes it necessary to work together with many stakeholders on possible solutions, avoiding paralysis by complexity. Most importantly, stakeholders need to invest in mutual understanding, keep an open communication, and feel invited to bring in solutions for their part of the chain.
