ISO 5667-5:2006 establishes principles to be applied to the techniques of sampling water intended for human consumption. For the purposes of ISO 5667-5:2006, water intended for human consumption comprises: all water either in its original state or after treatment, intended for drinking, cooking, food preparation, or other domestic purposes, regardless of its origin, plus all water used in any production undertaking for the manufacture, processing, preservation or marketing of products or substances intended for human consumption unless the competent national authorities are satisfied that the quality of the water cannot affect the wholesomeness of the foodstuff in its finished form. The guidance given in ISO 5667-5:2006 is confined to those circumstances where water is drawn from municipal or similar distribution systems (including individual systems) where prior treatment and/or quality assessment has resulted in the water being classified as suitable for drinking or potable process purposes. Specifically, ISO 5667-5:2006 is applicable to water that is in continuous supply relative to any stage of use up to and including the point of consumption in a distribution system. This includes distribution within large buildings in which additional water quality management might be applicable. ISO 5667-5:2006 is also applicable to sampling situations that can arise relative to the investigation of system defects or emergency situations where the safety of sampling operatives is not compromised. ISO 5667-5:2006 does not provide guidance for water sources or for products generated by using drinking water. The followings items are examples of cases not addressed by the present document: the sampling of source water, for example groundwater and surface water impoundments; sampling of drinking water supplies derived from non-continuous sources (for example, from road tankers); sampling of bulk storage of water on airplanes, trains and ships; the sampling of beverage products (including bottled waters) or food containing potable water used in its preparation; sampling of drink vending machines that dispense unsealed cups of drinks.
Abstract
Overview
ISO 5667-5:2006 - Water quality - Sampling - Part 5 provides guidance on sampling drinking water from treatment works and piped distribution systems. It sets out principles for selecting sample locations, collecting and handling samples, and designing sampling programmes for water intended for human consumption (drinking, cooking, domestic use) and for potable process water used in food production (unless national authorities conclude water quality cannot affect final products). The guidance applies to continuously supplied municipal or similar distribution systems, including internal distribution in large buildings, and to sampling during investigations of system defects or emergencies (where sampler safety is maintained).
Key topics and technical requirements
- Scope and definitions: Clarifies what is meant by drinking water and potable process water and the limits of applicability (excludes source water, non-continuous supplies, bottled beverages, bulk transport on vehicles/aircraft/ships, and vending-machine cup-dispensed drinks).
- Design of sampling programmes: Programme design should follow ISO 5667-1; microbiological investigations should conform to ISO 19458.
- Sampling equipment and containers: Recommendations reference ISO 5667-1 and ISO 5667-3 for container preparation; on-line sensors to ISO 15839; microbiological sampling equipment to ISO 19458.
- Sample collection locations: Principles for choosing representative locations - intake and post-treatment outlets, distribution network nodes, vulnerable points (low-pressure zones, ends of system, loops), service reservoirs (inlet/outlet), and large building intakes.
- Collection and handling: Guidance includes pre-collection cleaning, disinfection, flushing, on-site measurements, sample volumes, contamination precautions, order of sampling, frequency/timing, and records/identification.
- Specialized sampling: Considerations for physical, chemical, radiological, microbiological, biological and virological analyses, field measurements and continuous monitoring.
- Quality assurance: Emphasis on sampling manuals, training, verification and independent review to ensure sampling quality.
Applications and users
ISO 5667-5 is primarily used by:
- Water utilities and treatment plant operators for routine compliance and performance monitoring.
- Distribution system managers and large building facilities (hotels, hospitals, offices) for internal water quality control.
- Public health authorities and environmental laboratories planning sampling campaigns and interpreting results.
- Food and beverage process control teams monitoring potable process water inputs (subject to national guidance).
- Emergency response teams investigating contamination incidents in piped systems.
