Article Synopsis
- This study examines how well different types of Granular Activated Carbon (GAC) and an anion exchange resin can remove PFAS and other contaminants from groundwater used for drinking water production.
- GAC was effective initially, showing low breakthrough rates for contaminants, but its efficiency decreased over time; however, the resin improved the removal of certain acid compounds but not all.
- Some contaminants were effectively removed, but the use of resin filters led to the detection of new contaminants in the treated water, raising concerns about drinking water safety.
Small water supplies face similar problems worldwide, regardless of ownership or management type. Non-compliance with water quality regulations is more frequent in small supplies than in large ones, as are waterborne disease outbreaks. The new European Union Drinking Water Directive requires risk-based approach (RBA) to secure water safety as is recommended in the World Health Organization's Guidelines for drinking water quality through 'water safety plans'.

- Polyethylene (PE) pipes are preferred for water supply systems due to their strength and resistance to corrosion, but studies indicate that organic compounds can leach into drinking water from these pipes.
- The research involved a two-step approach: first, laboratory experiments analyzed the migration of volatile and semi-volatile organic compounds from high-density polyethylene (HDPE) pipes, revealing 133 detectable compounds, including harmful substances like flame retardants.
- The second step examined drinking water from a Copenhagen distribution system, identifying 51 compounds, of which 12 were linked to HDPE, with many detected compounds originating from rubber seals rather than the HDPE itself.
Drinking water softening is often implemented to increase consumer convenience e.g. by reducing lime scaling and soap use.

The Nordic countries have an abundance of clean fresh water as a source for drinking water supplies. They have followed developments in safeguarding water, both the recommendations of the World Health Organization framework for safe drinking water and European legislation.
