This document gives guidelines for the design of sampling programmes, techniques and the handling and preservation of samples of water, from natural and man-made lakes during open-water and ice-covered conditions. This document is applicable to lakes with and without aquatic vegetation. Guidance on sampling for microbiological examination is not included. For specific guidance on the sampling for microplastics, see ISO 5667-27.

Overview

ISO 5667-4:2026 is an International Standard from ISO providing comprehensive guidelines for the sampling of water from lakes-both natural and man-made-in various environmental conditions. This standard delivers reliable direction for designing sampling programmes, choosing appropriate sampling techniques, and handling and preserving water samples from open-water and ice-covered conditions. By following this guidance, professionals can ensure both the consistency and quality of water sampling processes in diverse lacustrine environments. It is applicable to lakes with or without aquatic vegetation, enhancing its utility for a broad range of water quality monitoring scenarios. However, it does not cover microbiological sampling or sampling specific to microplastics (see ISO 5667-27 for that guidance).

Key Topics

Sampling Programme Design

Defining objectives and parameters
Selecting appropriate sampling locations (both horizontal and vertical distribution)
Frequency and timing of sampling for short- and long-term monitoring

Equipment Selection, Cleaning, and Maintenance

Choosing non-contaminating materials for sampling devices
Regular mechanical and chemical cleaning of equipment
Documentation of equipment calibration and maintenance

Sampling Methods and Procedures

Use of grab, composite, and integrated samples depending on investigation needs
Procedures for sampling during both open-water and ice-covered conditions
Prevention of contamination during collection and handling

Sample Handling, Preservation, and Transport

Immediate cooling or freezing where applicable
Use of appropriate containers based on analytical parameters
Correct labeling, documentation, and chain of custody

Quality Assurance and Control

Incorporation of field, travel, and filter blanks to assess potential contamination
Adherence to formal QA/QC protocols as referenced in related ISO standards

Occupational Health and Safety

Implementing safety measures, particularly for sampling from boats or through ice

Applications

ISO 5667-4:2026 is invaluable for organizations and professionals responsible for monitoring and managing water quality in lakes. Its practical applications include:

Environmental Monitoring: Ensures representative sampling for trend analysis and assessment of water body status.

Compliance Testing: Supports regulatory agencies and laboratories in meeting local, national, or international legal and quality requirements.

Research Projects: Provides standardized methods for academic or governmental research on limnology, pollution, or ecosystem health.

Industrial and Municipal Purposes: Facilitates compliance with permits and monitoring of potential impacts from effluents or water abstractions.

Public Health and Recreation: Supports risk assessments where water quality affects human health or recreational activities.

Event-driven or Emergency Sampling: Guides procedures for investigating accidental spills or unusual events affecting lake water quality.

By following this standard, users achieve more accurate, comparable, and legally defensible results in lake water sampling projects.

Related Standards

ISO 5667-1: Guidance on the design of sampling programmes and sampling techniques in general for water quality assessment.

ISO 5667-3: Details the preservation and handling of water samples post-collection.

ISO 5667-14: Specific requirements for the quality assurance of water sampling processes.

ISO 5667-27: Guidance specifically focused on sampling for microplastics in water.

ISO 7027: Procedures for measuring water turbidity, relevant during certain sampling and field assessment protocols.

Adhering to ISO 5667-4:2026 ensures alignment with international best practices for lake water quality sampling, supports consistent data quality, and enhances the reliability of environmental decision-making. For practitioners working with water bodies, this standard is an essential reference for ensuring robust sampling procedures, optimal sample integrity, and defensible water quality results.
