Overview
EN ISO 10870:2012 - Water quality - Guidelines for the selection of sampling methods and devices for benthic macroinvertebrates in fresh waters - provides criteria for selecting sampling methods and devices used to evaluate benthic macroinvertebrate populations in rivers, canals, lakes and reservoirs. It gives guidance on the design, operation and performance characteristics of sampling equipment to support reliable measurement of taxonomic composition, abundance and diversity in freshwater biological monitoring. The standard is intended for macroinvertebrates (>0.5 mm) and is not suitable for meiofauna.
Key topics
- Scope and objectives
- Guidance for monitoring ecological status, surveillance, operational and investigational programmes, pollution diagnosis, conservation and biodiversity assessment.
- Device and method selection
- Criteria to match sampling device to habitat type, target taxa and study objectives.
- Emphasis on performance characteristics, repeatability and suitability for routine monitoring versus research-only methods.
- Sampling programme design
- Recommendations on station selection, replication, seasonality and pilot surveys to ensure statistical power and comparability.
- Consideration of local hydrology, topography and existing data.
- Sampling devices covered
- Handnet, Surber sampler, box and cylinder samplers, naturalist’s dredge.
- Grabs: Ekman‑Birge, Ponar, Van Veen, polyp (orange peel) grab.
- Air‑lift samplers, core and tube samplers, colonization samplers.
- Terminology and measurement
- Definitions such as abundance, diversity, semi‑quantitative/quantitative observation and habitat types.
- Quality assurance and biosecurity
- Advice on preventing transfer of diseases and invasive species during sampling.
- Safety
- Warning that working in/around water is hazardous; users must apply appropriate health and safety measures.
Applications
- Environmental and regulatory monitoring of water quality and ecological status.
- Design and implementation of biomonitoring surveys for rivers, lakes, reservoirs and canals.
- Pollution impact assessments, habitat restoration monitoring and biodiversity/conservation studies.
- Standardizes sampling to support comparable datasets for trend detection, compliance and research.
Who should use this standard
- Environmental consultants and field survey teams
- Water quality laboratories and monitoring agencies
- Aquatic ecologists and researchers
- Conservation organizations and regulatory bodies
