Full title and description

STB BS EN 1476-1996 (2000) — Water quality — Sampling — Guidance on sampling techniques from lakes, reservoirs and ponds.

Abstract

This standard provides guidance on the collection of representative water samples from still inland waters such as lakes, reservoirs and ponds for the purpose of water quality analysis. It describes sampling locations, timing, equipment, sample volumes, sampling procedures (including depth-specific sampling), handling, preservation and transport to ensure that samples reflect in-situ conditions and remain suitable for subsequent laboratory tests.

Scope

This standard gives recommendations for taking water samples from lakes, reservoirs and ponds for the analysis of physical, chemical and microbiological parameters. It covers principles for choosing sampling points and depths, describes equipment and containers, specifies on-site procedures to minimise contamination and changes to sample composition, and gives guidance on preservation, labelling and transport. It does not specify analytical methods nor limits for water quality; those are covered by separate standards.

Key topics and requirements

• Selection of representative sampling sites (considering inflows, stratification, recreational zones and ecological interest points).
• Timing and frequency of sampling to capture temporal variability (seasonal, diurnal and event-driven changes).
• Depth-specific sampling procedures, including sampling from surface, thermocline and bottom layers using appropriate devices (e.g. Ruttner or Van Dorn samplers).
• Requirements for sampling equipment and containers — materials, cleaning, rinsing and avoidance of contamination.
• Sample volumes, preservation techniques (cooling, chemical preservatives) and holding times to maintain sample integrity before analysis.
• On-site metadata recording: weather, water level, water temperature profile, dissolved oxygen, pH and other field measurements.
• Labelling, chain of custody and transport instructions to ensure traceability and legal defensibility of results.

Typical use and users

Used by environmental laboratories, water quality consultants, reservoir and lake managers, environmental protection agencies, researchers and utilities involved in monitoring and assessing inland still water bodies. It is applied for routine monitoring, compliance sampling, impact studies and research sampling campaigns.

Related standards

Related documents include standards and guidance on sampling from rivers/streams, groundwater and estuaries, plus analytical method standards for specific parameters. Examples include standards for sampling flowing waters, groundwater sampling, sample handling and preservation, and individual test methods for microbiology and chemistry. Users commonly consult these in combination to form a complete monitoring protocol.
