Full title and description

ISO 5667-13:2011 — Water quality — Sampling — Part 13: Guidance on sampling of sludges. This international standard provides guidance on planning and carrying out representative sampling of sludges produced by wastewater treatment works, water treatment works and industrial processes (including sludges of similar characteristics such as septic-tank sludges). It covers selection of sampling locations, sampling techniques, sample handling and the design of sampling programmes for characterisation and monitoring purposes.

Abstract

ISO 5667-13:2011 gives practical guidance aimed at obtaining representative samples of sludges for physical, chemical and biological testing. Topics include principles for sample representativity, choice between grab and composite sampling, equipment selection, handling, preservation, documentation and safety considerations relevant to sludge matrices. The guidance is applicable to all types of sludge from municipal and industrial sources.

Scope

This part of ISO 5667 provides guidance on the design of sampling programmes and on sampling techniques specifically for sludges arising from wastewater treatment works, water treatment works and industrial processes. It is intended to be applied where representative samples of sludge are required for compliance testing, process control, environmental monitoring and research. The scope covers a range of sludge types and addresses practical issues of heterogeneity, solids content, dewatering and safety during sampling.

Key topics and requirements

• Principles for obtaining representative sludge samples (accounting for heterogeneity and stratification).
• Design of sampling programmes: objectives, sampling frequency, number of increments and composite vs grab sampling.
• Selection and use of sampling equipment appropriate for sludge matrices (probes, bailers, mixers, augers, samplers for dewatered cake, etc.).
• Sample handling, preservation, transport and storage to minimise changes before analysis (including temperature control and container selection).
• Safety, personal protection and environmental precautions when sampling potentially hazardous sludges.
• Documentation, labelling, chain of custody and quality assurance measures to ensure traceability and data integrity.

Typical use and users

Primary users include environmental and wastewater laboratories, utility operators (wastewater and water treatment plants), industrial process engineers, environmental consultants, regulatory agencies and researchers involved in sludge characterisation, monitoring, disposal or reuse (for example agricultural land application). The standard is used to design sampling campaigns, to write sampling procedures and to train personnel in appropriate techniques for sludge sampling.

Related standards

ISO 5667-13 is part of the broader ISO 5667 series on water quality sampling. Relevant related parts include ISO 5667-1 (general guidance on design of sampling programmes and techniques), ISO 5667-3 (preservation and handling), ISO 5667-6 (rivers and streams), ISO 5667-11 (groundwaters) and others in the series that address specific matrices and QA aspects. Users commonly consult the series as a whole to ensure coherent sampling practice across water and sludge matrices.

FAQ

Q: What is this standard?

A: ISO 5667-13:2011 is an international standard giving guidance on planning and performing representative sampling of sludges from wastewater, water treatment and industrial processes.

Q: What does it cover?

A: It covers principles and practical techniques for collecting, handling and preserving sludge samples, designing sampling programmes (frequency, number of increments, composite vs grab), equipment selection, safety and documentation required for reliable analytical results.

Q: Who typically uses it?

A: Environmental and analytical laboratories, wastewater and water utility operators, industrial operators, environmental consultants, regulators and researchers use the standard to develop sampling procedures and quality-assured sampling campaigns.

Q: Is it current or superseded?

Q: Is it part of a series?

A: Yes — ISO 5667-13 is one part of the ISO 5667 series, which provides guidance on sampling for different water- and sludge-related matrices and on general sampling programme design and QA. Consult other parts (e.g., ISO 5667-1, -3, -6, -11, -14, etc.) for complementary guidance.
