Safe drinking water is essential for the health of all people and ensuring safe water at the national level requires a framework comprised of regulation and responsible actors. A new analysis of the current national framework in Iceland explores the interplay between various safe drinking water actors on a national level was recently published in the International Journal of Hygiene and Environmental Health. The analysis classifies regulators according to their roles in addressing drinking water quality, water protection and health. The associated legislations are listed and discussed and the role of the responsible actors are examined. The legislative environment for the water suppliers is also explored. Iceland’s water safety framework is mostly in place. While the analysis identifies measurable successes, there are ongoing challenges to addressing the multi-faceted aspects of ensuring a safe water supply.
The main challenges include the need for improved guidance in operating a water safety plans (WSP) at water utilities, especially at the smaller utilities. A lack of systematic external audit and surveillance of these plans slowed further development of the WSP. The analyses demonstrated a need to revise the current drinking water regulation in light of the experience gained since it was implemented roughly 10 years ago. These include issues like roles and responsibility in daily operations as well as maintenance and define more clearly what a regulated water utility is. Communication to the general public was in many cases found lacking, both with regard to incident reporting as well as general information about the drinking water and compliance.
Several of the challenges can be linked to a need for additional training or increases in other resources required to implement monitoring and enforcement. For instance, while guidelines call for surveillance of water intake and system status, the smaller water utilities lag behind larger utilities in monitoring water supply status.
The analysis showed that most of the legal requirements are in place, both at the institution level and at the municipal level and are mostly functional. The analysis indicated a considerably success in providing safe water to the general public. A previous 2012 study found that implementation of WSPs in localities reduced the occurrence of e. coli detections and instances of diarrheal disease.
The water utilities that have implemented water safety plans experience a positive impact on the utility culture, improved compliance to regulation, and enhanced public health.
