There is a growing misuse of regulatory terminology in the field of water for human consumption, particularly the phrase “drinking water analysis according to Legislative Decree 102\/2025.”<\/em><\/p>

Technically and legally, this wording is incorrect and requires clarification.<\/p>

In fact, Legislative Decree No. 102 of June 19, 2025<\/strong>, is a measure containing supplementary and corrective provisions to Legislative Decree No. 18 of February 23, 2023<\/strong>, which remains the current regulatory reference for the quality of water for human consumption<\/p>

As a result, the regulatory framework has not been replaced, but updated. Therefore, analytical activities continue to be conducted in accordance with Legislative Decree 18\/2023, as amended. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

<\/p>

The distinction is substantive, not just formal: it affects the correctness of technical documentation and alignment with regulatory requirements<\/strong>.<\/p>

The main changes introduced by Leg. 102\/2025<\/h2>

The changes introduced do not redefine the analytical system, but increase its level of technical and managerial complexity, directly affecting control, monitoring and risk management activities.<\/p>

1) Evolution of parameters and emerging contaminants.<\/h3>

The decree strengthens control over emerging contaminants, with particular reference to per- and polyfluoroalkyl substances(PFASs<\/strong>) and the introduction of the parameter on trifluoroacetic acid(TFA<\/strong>), for which progressive monitoring and compliance obligations are envisaged starting in 2027<\/p>

This update involves an adjustment of sampling strategies and analytical methods, with an increasing focus on sensitivity and robustness of the data.<\/p>

2) Centrality of materials in contact with water.<\/h3>

The decree introduces a harmonized system for the evaluation of materials and reagents that come into contact with water intended for human consumption.<\/p>

Filter materials, chemical reagents and devices must meet requirements defined at the European level(ReMaF<\/strong>), with procedures for authorization, compliance and marking. There are also transitional phases for compliance, including in relation to limits on metals such as lead <\/p>

Control thus extends from water to the technological system that treats and distributes it.<\/p>

3) Structuring of controls, data and transparency.<\/h3>

The control system is made more structured through centralized information tools and data reporting requirements.<\/p>

The AnTeA platform<\/strong> takes a central role in information collection and management, while stricter timelines for reporting noncompliance and transparency obligations to end users are introduced<\/p>

The evolutionary model is that of a continuous, traceable and accessible system.<\/p>

4) Strengthening the preventive approach and risk management<\/h3>

Water Security Plans (WSPs) are being strengthened and tightened, with an extension of the risk-based approach throughout the entire drinking water supply chain.<\/p>

In this context, the management of microbiological risk, including Legionella<\/strong>, also becomes important and becomes a structural element in control protocols for specific categories of high-occupancy buildings.<\/p>

The approach is no longer limited to compliance verification, but oriented toward systemic risk prevention and control.<\/p>

5) Redefinition of responsibilities along the supply chain.<\/h3>

The decree clarifies and expands the scope of responsibilities of stakeholders to include hydropotable managers, economic operators and internal distribution systems.<\/p>

Water quality is then followed all the way through to the point of use, with an integrated view between network, facilities and end users.<\/p>

Legislative Decree 102\/2025 does not introduce new analyses in the strict sense, but it does change the technical context in which they are designed and interpreted. <\/p>

Conclusions<\/h2>

Legislative Decree 102\/2025<\/strong> is a relevant update<\/strong> of the drinking water regulatory framework, but it does not change the basic reference.<\/p>

The system remains the one defined by Legislative Decree 18\/2023, now evolved to a more integrated model geared toward risk prevention and consistent with the European regulatory environment. <\/p>

The LAC approach<\/h2>

We at LAC operate in this context by providing analytical and technical\/regulatory support, with an approach that integrates data, method and legislative interpretation.<\/p>

The activity is not limited to analysis, but includes establishing monitoring plans, critically reading the results, and supporting the management of critical issues.<\/p>

Because, in an increasingly complex system, quality depends not only on the measured parameter, but on the ability to interpret it correctly.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
