Access to clean, safe, and high-quality water is both a basic human right and a cornerstone of modern business and public health. In the face of growing concerns about environmental sustainability, regulatory compliance, and public confidence, international water quality standards have become indispensable tools for organizations in every sector. This article provides an easy-to-digest overview of four pivotal water quality standards currently shaping global best practices—helping businesses not just comply, but also thrive by improving efficiency, scaling effectively, and ensuring the safety and security of their water supply and use.
Overview / Introduction
Water quality standards are the backbone of safe water management. Whether you’re responsible for municipal supply, industrial processes, building materials, or environmental monitoring, these standards establish a common language and a benchmark for excellence. From reducing health risks to protecting brand reputation and supporting sustainable growth, implementing recognized water quality requirements is now a must for forward-thinking organizations.

Detailed Standards Coverage
EN 14944-2:2025 - Ensuring Safe Contact: Cement-Based Materials & Water
Influence of cement based products on water intended for human consumption – Test methods – Part 2: Influence of site-applied cement based materials and associated non-cement based products/materials on organoleptic parameters and migration of organic substances (TOC)
EN 14944-2:2025 addresses a critical intersection between construction and drinking water safety. This standard specifies methods to determine how site-applied cement-based products and associated non-cement products influence the organoleptic qualities (taste, odour, colour, turbidity) and the migration of organic substances—especially total organic carbon (TOC)—in water intended for human consumption.
The scope includes all site-formed or applied cement-based materials such as mortars and tiles used in water transport and storage infrastructure. Importantly, it covers not only the cement products but also associated non-cement materials that might come into contact with potable water. It’s applicable to public water utilities, contractors, construction material suppliers, and anyone involved in the installation or renovation of water infrastructure.
Implementing EN 14944-2 ensures safe water post-construction and helps organizations avoid liability from unwanted changes in water quality caused by material leaching. The test methods outlined help organizations rigorously assess products before and after installation, providing confidence in compliance and guiding innovation in safer material design.
Key highlights:
Sets procedures for evaluating taste, odour, colour, turbidity, and TOC in water after contact with site-applied cement and related materials
Applies to both cement and non-cement-based products/materials
Provides detailed test protocols, reporting requirements, and evaluation for product approval

EN 17971:2024 - Ozone Biocide Generation for Water Treatment
Devices for in-situ generation of biocides – Ozone
EN 17971:2024 sets the standard for devices that generate ozone biocides directly at the point of use, such as in water treatment plants or swimming pool systems. Ozone is a powerful disinfectant, and this standard defines construction, performance, safety, and testing requirements for all equipment generating and dosing ozone.
Covering technologies like dielectric barrier discharge, electrolysis, and UV irradiation, EN 17971 ensures that in-situ ozone generators are designed, installed, operated, and maintained safely and efficiently. The standard is vital for operators of municipal waterworks, industrial water treatment, recreational facilities, and food-and-beverage operations relying on ozone for microbial control and oxidative processes.
Key areas covered include:
Design requirements for ozone generators and auxiliary equipment
Safety protocols to protect workers and prevent environmental ozone leaks
Test methods for validating performance (ozone output, concentration, dosing accuracy)
Maintenance, documentation, and operational guidelines for long-term reliability
Adhering to EN 17971 lowers the risk of system failures, enhances operational safety, helps meet EU Biocidal Product Regulation (BPR), and boosts public trust by assuring high standards in water
disinfection.
Key highlights:
Regulates in-situ ozone generation and dosing equipment for water treatment
Integrates with EU BPR and REACH regulatory frameworks
Mandates reporting, documentation, and regular testing for system integrity

EN ISO 23196:2023 - Measuring Biological Effects: BEQ Concentration Calculation
Water quality – Calculation of biological equivalence (BEQ) concentrations (ISO 23196:2022)
EN ISO 23196:2023 provides a standardized method to calculate biological equivalence (BEQ) concentrations using in vitro bioassays. BEQ concentrations are crucial for understanding the biological impact of water contaminants—they express the effect of a water sample in terms of a reference chemical compound.
This standard is applicable to analysts, laboratories, environmental monitoring programs, and regulatory bodies seeking harmonized, reliable ways to compare biological effects across sites, scenarios, or chemicals. The procedures outlined help translate complex biological responses (like enzyme changes or cell growth) into actionable concentration values, driving better risk assessment, reporting, and regulation.
Particularly valuable for organizations conducting routine or investigative water monitoring, this standard supports advanced effect-based monitoring, the setting of effect-based trigger values, and cross-lab comparability.
Key highlights:
Defines robust procedures for calculating BEQ concentrations from bioassay data
Supports any biological assay once validated for the test case
Drives harmonization and comparability across studies and laboratories

EN ISO 5667-3:2024 - Water Sampling, Preservation, and Handling
Water quality – Sampling – Part 3: Preservation and handling of water samples (ISO 5667-3:2024)
EN ISO 5667-3:2024 is the definitive guide on how to sample, preserve, handle, transport, and store all types of water samples for subsequent laboratory analysis. This standard is indispensable for anyone collecting samples for chemical, physicochemical, hydrobiological, microbiological, or radiochemical analysis, especially when on-site analysis isn’t feasible.
Key aspects include recommendations for:
Sample container selection and preparation
Chain-of-custody protocols and traceability
Preservation techniques to prevent changes or contamination before analysis
Handling procedures specific to different analyte types (e.g., metals, organics, microbes)
Legal and best practice documentation for regulatory compliance
It specifically excludes passive, ecotoxicological, and microplastic samples (handled under other standards) and points to related documents for advanced or unusual sample types. Proper application minimizes risk of false results, loss of integrity, and regulatory non-compliance.
Key highlights:
Comprehensive guidance on all aspects of sample management
Default protocols for storage times and analyte-specific preservation
Cross-references to harmonize with other international sampling standards

Industry Impact & Compliance
Water quality standards are more prominent than ever due to increased regulatory scrutiny, consumer awareness, and risks from climate change and pollution. For businesses:
Safe Practice: Ensuring water safety avoids public health issues and legal claims
Market Trust: Certification and compliance send strong signals of responsibility to regulators, customers, and investors
Operational Security: Strong quality controls reduce the risk of production failures, recalls, and reputational damage
Scalability: Adhering to standardized methods supports efficient scaling—national and global expansion is easier with clear, repeatable processes
Cost Control: Efficient sampling, testing, and monitoring prevent costly errors, rework, and waste
On the flip side, failing to comply can mean fines, product bans, operational shutdowns, and lasting brand damage.
