This document specifies a method for the determination of organically bound halogens fluorine, chlorine, bromine and iodine which are adsorbable on activated carbon. Adsorption takes place on activated carbon packed in columns.
The method is applicable for the determination of:
≥ 2 µg/l AOF, expressed as F;
≥ 10 µg/l AOCl, expressed as Cl;
≥ 1 µg/l AOBr, expressed as Br;
≥ 1 µg/l AOI, expressed as I.
The method is applicable for the determination of adsorbable organically bound fluorine, chlorine, bromine and iodine in water, e.g. in groundwater, surface water, bank filtrate, drinking water, aqueous eluates, cooling water and wastewater.
The working range is limited by the capacity of the activated carbon, the process blank and the capacity of the chromatographic separation column. Sample dilution into the working range can be required.
The range of application can be extended to lower concentrations with lower process blanks e.g. using low blank activated carbons.
The method can also be applied for samples containing suspended solids. Halogens adsorbed on the suspended solids (e.g. undissolved halides) are also determined. Filtration of the sample prior to analysis using a membrane filter (0,45 µm) allows the separate determination of dissolved adsorbable and particulate bound fractions of organically bound fluorine, chlorine, bromine or iodine.
Results from an international interlaboratory trial are presented in Annex K.

This document specifies methods for the determination of five selected estrogens in whole water samples listed in Table 1 (see Clause 4). The methods are based on solid-phase extraction (SPE; disk or cartridge) followed by liquid or gas chromatography-mass spectrometry detection (tandem mass spectrometry or high resolution mass spectrometry). Depending on the sample preparation chosen, the sample preparation can be applicable to the analysis of selected estrogens in drinking water, groundwater and surface water containing suspended particulate matter (SPM) up to 500 mg/l, dissolved organic carbon (DOC) content up to 14 mg/l (whole water samples).
The lower application range defined as verified limit of quantification can vary depending on the methods, the sensitivity of the equipment used and the matrix of the sample. The range is 0,006 ng/l to 1 ng/l for 17alpha-ethinylestradiol (EE2) and 0,038 ng/l to 1 ng/l for the other estrogens in drinking water, ground water and surface water. The upper limit of the working range is approximately tens of nanograms per litre.
For application that targets the measurements of very low level concentrations (between the lowest LOQ and 0,1 ng/l), every single step of the procedure becomes critical.
The methods can be used to determine further estrogens or hormones in other types of water, for example treated wastewater, if accuracy has been tested and verified for each case as well as storage conditions of both samples and reference solutions have been validated.

This document provides guidance on characterizing the modifications of river hydromorphological features described in EN 14614:2020. Both standards focus more on morphology than on hydrology and continuity, and include a consideration of sediment and vegetation. This document will enable consistent comparisons of hydromorphological forms and processes between rivers within a country and between different countries in Europe, providing guidance for broad-based characterization across a wide spectrum of hydromorphological modification of river channels, banks, riparian zones and floodplains. Although of lesser focus, it considers the indirect effects of catchment-wide modifications to these river and floodplain environments. Its primary aim is to assess ‘departure from naturalness’ as a result of historical and modern human pressures on river hydromorphology, and it suggests suitable sources of information (see EN 14614:2020, Table A.1) which may contribute to characterizing the modification of hydromorphological properties. In doing so, it does not replace methods that have been developed for local assessment and reporting.
Decisions on river management for individual reaches or catchments require expert local knowledge and vary according to river type.

This document gives guidelines for the restoration of rivers, including their channels, riparian zones and floodplains. The word ‘river’ is used as a generic term to describe permanently flowing and intermittent watercourses of all sizes, with the exception of artificial water bodies such as canals. Some aspects of landscape restoration beyond the boundaries of what are often considered typical river processes are also considered.
A clear framework of guiding principles to help inform the planning and implementation of river restoration work is provided. These principles are applicable to individuals and organizations wishing to restore rivers, and stress the importance of monitoring and appraisal. This document makes reference to existing techniques and guidance, where these are appropriate and within the scope of this document.
This document gives guidelines on:
- the core principles of restoration;
- aims and overall outcomes of river restoration;
- the spectrum of typical approaches to river restoration with a focus on those that are nature-based and restore both physical and ecological aspects;
- identifying opportunities for restoration and possible constraints, with a focus on physical and natural rather than socio-economic aspects;
- different scales of restoration and how restoration works across different catchments and landscapes;
- the importance of monitoring and appraising restoration work across the range of approaches and scales.

This document is concerned with the assessment of fish survival in pumping stations and hydropower plants, defined as the fraction of fish that passes an installation without significant injury. It does not concern indirect consequences of such installations, usually included in the notions ‘fish safety’ or ‘fish-friendliness’, like avoidance of fish affecting migration, behavioural changes, injury during attempted upstream passage, temporary stunning of fish resulting in potential predation, or depleted oxygen levels.
This document applies to pumps and turbines in pumping stations and hydropower plants that operate in or between bodies of surface water, in rivers, in streams or estuaries containing resident and/or migratory fish stocks. Installations include centrifugal pumps (radial type, mixed-flow type, axial type), Archimedes screws, and water turbines (Francis type, Kaplan type, Bulb type, Straflo type, etc.).
The following methods to assess fish survival are described:
— Survival tests involving the paired release of live fish, introduced in batches of test and control fish upstream and downstream of an installation, and the subsequent recapture in full-flow collection nets. The method is applicable to survival tests in the field and in a laboratory environment. (Clause 6);
— A validated model-based computational method consisting of a blade encounter model and correlations that quantify the biological response to blade strike (Clause 7).
The computational method can be used to scale results from laboratory fish survival tests to full-scale installations operating under different conditions (Clause 8).
The survival tests and computational method can also be applied to open-water turbines, with the caveats mentioned in Annex C.
The results of a survival test or a computed estimation can be compared with a presumed maximum sustainable mortality rate for a given fish population at the site of a pumping station or hydropower plant. However, this document does not define these maximum rates allowing to label a machine as “fish-friendly”, nor does it describe a method for determining such a maximum.
This document offers an integrated method to assess fish survival in pumping stations and hydropower plants by fish survival tests and model-based calculations. It allows (non-)government environmental agencies to evaluate the impact on resident and migratory fish stocks in a uniform manner. Thus the document will help to support the preservation of fish populations and reverse the trend of declining migratory fish stocks. Pump and turbine manufacturers will benefit from the document as it sets uniform and clear criteria for fish survival assessment. Further, the physical model that underlies the computational method in the document, may serve as a tool for new product development. To academia and research institutions, this document represents the baseline of shared understanding. It will serve as an incentive for further research in an effort to fill the omissions and to improve on existing assessment methods.

This document establishes key principles for the investigation of microplastics in drinking water and water with low content of natural suspended solids using a microscopy technique coupled with vibrational spectroscopy.
This method is applicable to:
— determine the size of microplastics [which range from 1 µm to 5 000 µm], count them and classify them by size range;
— identify the chemical composition of microplastics, the main ones (most used in industry and most abundant in the environment) being: polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC), polystyrene (PS), polytetrafluoroethylene (PTFE), polyvinyl chloride (PVC), polyamide (PA), polymethyl methacrylate (PMMA) and polyurethane (PU);
This method is applicable to water with a low content of organic matter and other suspended matter as defined in ISO 6107 (1 mg/l to 100 mg/l or lower when interfering with the determination), i.e.,
— ultrapure water;
— water intended for human consumption;
— raw groundwaters.
Given the very low concentrations of microplastics usually present in these waters, special attention needs to be paid to potential sources of contamination during sample preparation.
This method is intended to determine and characterize large numbers of particles in the sample in automatic mode.
This method can also identify the nature of the other particles that are outside the scope of this document, for example minerals, proteins, cellulose and pigments.
This method does not apply to the characterization of substances intentionally added to or adsorbed on the surface of microplastics. This method does not apply to the determination of the geometric shape of microplastics.

This document specifies methods for the determination of five selected estrogens in whole water samples listed in Table 1 (see Clause 4). The methods are based on solid-phase extraction (SPE; disk or cartridge) followed by liquid or gas chromatography-mass spectrometry detection (tandem mass spectrometry or high resolution mass spectrometry). Depending on the sample preparation chosen, the sample preparation can be applicable to the analysis of selected estrogens in drinking water, groundwater and surface water containing suspended particulate matter (SPM) up to 500 mg/l, dissolved organic carbon (DOC) content up to 14 mg/l (whole water samples).
The lower application range defined as verified limit of quantification can vary depending on the methods, the sensitivity of the equipment used and the matrix of the sample. The range is 0,006 ng/l to 1 ng/l for 17alpha-ethinylestradiol (EE2) and 0,038 ng/l to 1 ng/l for the other estrogens in drinking water, ground water and surface water. The upper limit of the working range is approximately tens of nanograms per litre.
For application that targets the measurements of very low level concentrations (between the lowest LOQ and 0,1 ng/l), every single step of the procedure becomes critical.
The methods can be used to determine further estrogens or hormones in other types of water, for example treated wastewater, if accuracy has been tested and verified for each case as well as storage conditions of both samples and reference solutions have been validated.
