Key takeaway
What This Development Means
The European Chemicals Agency has introduced new guidelines under the Drinking Water Directive to enhance the safety of materials in contact with drinking water. Effective January 2025, these guidelines ensure rigorous testing and approval processes to protect public health across the EU.
What are the new EU guidelines for drinking water safety?
The new EU guidelines under the Drinking Water Directive focus on testing and approving materials in contact with drinking water. They aim to protect public health by ensuring that all substances meet stringent safety standards before being included in the European positive list.
How do the new guidelines affect manufacturers?
Manufacturers must comply with the new guidelines by submitting detailed applications to the ECHA, covering the identity, composition, and intended use of substances. This ensures transparency and accountability in the approval of materials used in drinking water systems.

The European Chemicals Agency (ECHA) has released new guidelines under the Drinking Water Directive (DWD) to enhance the safety of materials in contact with drinking water. Effective January 2025, these guidelines aim to protect public health by regulating the testing and approval of substances used in water supply systems across the European Union.
Understanding The New Guidelines
The updated guidelines, detailed in the DWD Guidance Volume I, focus on the methodologies for testing starting substances, compositions, and constituents intended for use in materials that come into contact with drinking water. These guidelines are part of the broader effort to ensure that all materials meet stringent safety standards before being included in the European positive list (EUPL).
Key Changes And Requirements
The guidelines introduce comprehensive testing methodologies, including the assessment of physico-chemical properties, toxicological data, and migration potential of substances. A significant emphasis is placed on identifying relevant chemical species and assessing their potential risks to human health. The guidelines also require detailed reporting of the intended use of substances, including their technical function and concentration in materials.
Focus On Safety And Compliance
The guidelines mandate that all toxicological data be submitted in a robust study summary format, ensuring that the information is sufficient for conducting risk assessments. The ECHA requires that at least one key study or an acceptable adaptation rule be provided for each standard information requirement. This ensures that all materials are thoroughly evaluated for safety before approval.
Implications For Manufacturers
Manufacturers seeking approval for their products must adhere to these guidelines, which include submitting detailed applications to the ECHA. The applications must cover the identity, composition, and intended use of the substances, along with any existing EU or national-level authorisations. This process ensures transparency and accountability in the approval of materials used in drinking water systems.
Addressing Non-Intentionally Added Species (NIAS)
The guidelines also address the issue of non-intentionally added species (NIAS), which may form during the processing or use of materials. Manufacturers are required to identify and report any NIAS that might migrate into drinking water, ensuring that all potential risks are assessed and mitigated.
