This document specifies a method for the enumeration of Pseudomonas aeruginosa in water. The
method is based on the growth of target organisms in a liquid medium and calculation of the most
probable number (MPN) of organisms by reference to MPN tables.
This document is applicable to a range of types of water. For example, hospital waters, drinking water
and non‐carbonated bottled waters intended for human consumption, groundwater, swimming pool
and spa pool waters including those containing high background counts of heterotrophic bacteria.
This document does not apply to carbonated bottled waters, flavoured bottle waters, cooling tower
waters or marine waters, for which the method has not been validated. These waters are, therefore,
outside the scope of this document. Laboratories can employ the method presented in this document
for these matrices by undertaking appropriate validation of performance of this method prior to use.
The test is based on a bacterial enzyme detection technology that signals the presence of P. aeruginosa
through the hydrolysis of a 7‐amino‐4‐methylcoumarin aminopeptidase substrate present in a special
reagent. P. aeruginosa cells rapidly grow and reproduce using the rich supply of amino acids, vitamins
and other nutrients present in the reagent. Actively growing strains of P. aeruginosa have an enzyme
that cleaves the 7‐amido‐coumarin aminopeptidase substrate releasing a product which fluoresces
under ultraviolet (UV) light. The test described in this document provides a confirmed result within
24 h with no requirement for further confirmation of positive wells.

This International Standard specifies a method for the determination of total organic carbon (TOC), dissolved organic carbon (DOC), and for the determination of dissolved and particular bound nitrogen (TNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides under the oxidative conditions described. The procedure is carried out instrumentally.
NOTE 1 Generally the method can be applied for the determination of total carbon (TC) and total inorganic carbon (TIC) (see Annex A in the Outline).
The method is applicable for water (e.g. drinking water, raw water, ground water, surface water, sea water or waste water) containing suspended material of ≤ 100 μm of particle size (convention). Reduce particles of > 100 μm of size to pieces of particle size of ≤ 100 μm before injection. The method allows a determination of TOC/DOC ≥ 1 mg/l C and TNb ≥ 1 mg/l N.
NOTE 2 The determination of carbon concentrations > 0,3 mg/l to 1 mg/l is only applicable in special cases, for example drinking water, measured by highly sensitive instruments. Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together with the organic carbon. Volatile or purgeable organic carbon (VOC, POC) is not determined by this method. Dissolved nitrogen gas is not determined by this method. Generally, the working range is restricted by instrument dependant conditions (e.g. injection volume). Higher concentrations may be determined after appropriate dilution.

This document specifies conditions for the determination of 90Sr and 89Sr activity concentration in
samples of environmental water using liquid scintillation counting (LSC) or proportional counting (PC).
The method is applicable to test samples of drinking water, rainwater, surface and ground water,
marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after
proper sampling and handling, and test sample preparation. Filtration of the test sample and a chemical
separation are required to separate and purify strontium from a test portion of the sample.
The detection limit depends on the sample volume, the instrument used, the sample count time, the
background count rate, the detection efficiency and the chemical yield. The method described in this
document, using currently available LSC counters, has a detection limit of approximately 10 mBq l−1
and 2 mBq l−1 for 89Sr and 90Sr, respectively, which is lower than the WHO criteria for safe consumption
of drinking water (100 Bq·l−1 for 89Sr and 10 Bq·l−1 for 90Sr)[3]. These values can be achieved with a
counting time of 1 000 min for a sample volume of 2 l.
The methods described in this document are applicable in the event of an emergency situation.
When fallout occurs following a nuclear accident, the contribution of 89Sr to the total amount of
radioactive strontium is not negligible. This document provides test methods to determine the activity
concentration of 90Sr in presence of 89Sr.
The analysis of 90Sr and 89Sr adsorbed to suspended matter is not covered by this method.
It is the user’s responsibility to ensure the validity of this test method selected for the water samples
tested.

This document specifies a method for the physical pre-treatment and conditioning of water samples
and the determination of the activity concentration of various radionuclides emitting gamma-rays with
energies between 40 keV and 2 MeV, by gamma‑ray spectrometry according to the generic test method
described in ISO 20042.
The method is applicable to test samples of drinking water, rainwater, surface and ground water as well
as cooling water, industrial water, domestic and industrial wastewater after proper sampling, sample
handling, and test sample preparation (filtration when necessary and taking into account the amount
of dissolved material in the water). This method is only applicable to homogeneous samples or samples
which are homogeneous via timely filtration.
The lowest limit that can be measured without concentration of the sample or by using only passive
shield of the detection system is about 5·10-2 Bq/l for e.g. 137Cs1). The upper limit of the activity
corresponds to a dead time of 10 %. Higher dead times may be used but evidence of the accuracy of the
dead-time correction is required.
Depending on different factors, such as the energy of the gamma-rays, the emission probability per
nuclear disintegration, the size and geometry of the sample and the detector, the shielding, the counting
time and other experimental parameters, the sample may require to be concentrated by evaporation
if activities below 5·10-2 Bq/l need to be measured. However, volatile radionuclides (e.g. radon and
radioiodine) can be lost during the source preparation.
This method is suitable for application in emergency situations.

This document specifies a method for the measurement of 14C activity concentration in all types of
water samples by liquid scintillation counting (LSC) either directly on the test sample or following a
chemical separation.
The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water,
marine water, as well as cooling water, industrial water, domestic, and industrial wastewater.
The detection limit depends on the sample volume, the instrument used, the sample counting time, the
background count rate, the detection efficiency and the chemical recovery. The method described in
this document, using currently available liquid scintillation counters and suitable technical conditions,
has a detection limit as low as 1 Bq∙l−1, which is lower than the WHO criteria for safe consumption of
drinking water (100 Bq·l-1). 14C activity concentrations can be measured up to 106 Bq∙l-1 without any
sample dilution.
It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

This document specifies a method for the measurement of 210Pb in all types of waters by liquid scintillation counting (LSC). The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation. Filtration of the test sample is necessary. Lead‑210 activity concentration in the environment can vary and usually ranges from 2 mBq l-1 to 300 mBq l-1 [27][28]. Using currently available liquid scintillation counters, the limit of detection of this method for 210Pb is generally of the order of 20 mBq l-1 to 50 mBq l-1, which is lower than the WHO criteria for safe consumption of drinking water (100 mBq lâ’1).[4][6] These values can be achieved with a counting time between 180 min and 720 min for a sample volume from 0,5 l to 1,5 l. Higher activity concentrations can be measured by either diluting the sample or using smaller sample aliquots or both. The method presented in this document is not intended for the determination of an ultra-trace amount of 210Pb. The range of application depends on the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency). The method described in this document is applicable to an emergency situation. The analysis of Pb adsorbed to suspended matter is not covered by this method. It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

This document specifies a method for the quantification of twelve microcystin variants (microcystin-LR, -LA, -YR, -RR, -LY, -WR, -HtyR, -HilR, -LW, -LF, [Dha7]-microcystin-LR, and [Dha7]-microcystin-RR) in drinking water and freshwater samples between 0,05 µg/l to 1,6 µg/l. The method can be used to determine further microcystins, provided that analytical conditions for chromatography and mass spectrometric detection has been tested and validated for each microcystin. Samples are analysed by LC-MS/MS using internal standard calibration. This method is performance based. The laboratory is permitted to modify the method, e.g. increasing direct flow injection volume for low interference samples or diluting the samples to increase the upper working range limit, provided that all performance criteria in this method are met. Detection of microcystins by high resolution mass spectrometry (HRMS) as an alternative for tandem mass spectrometry (MS/MS) is described in Annex A. An alternative automated sample preparation method based on on-line solid phase extraction coupled to liquid chromatography is described in Annex B. When instrumental sensitivity is not sufficient to reach the method detection limits by direct flow injection, a solid phase extraction clean-up and concentration step is described in Annex C.

This document covers the system's components needed for the use of treated wastewater (TWW) for irrigation. Emphasis is placed on irrigation methods, mainly drip irrigation, as this method represents an efficient method of irrigation and water saving, while reducing the pollution of the crops. Despite the fact that water quality and filtration of treated wastewater (herein TWW) using drip irrigation are critical, open irrigation systems are more popular and are frequently used for irrigation with TWW and therefore are covered in this document. This document covers issues related to the main components of a TWW irrigation project, including the following: —   pumping stations; —   storage reservoirs; —   treatment facilities (for irrigation purposes); —   filtration and disinfection; —   distribution pipeline networks; —   water application devices: irrigation system components and treatment. This document is not intended to be used for certification purposes.

This document specifies a test method for the determination of iron-55 (55Fe) activity concentration in samples of all types of water using liquid scintillation counting (LSC). Using currently available liquid scintillation counters, this test method can measure the 55Fe activity concentrations in the range from the limit of detection up to 120 mBq l-1. These values can be achieved with a counting time between 7 200 s and 10 800 s for a sample volume from 0,5 l to 1,5 l. Higher activity concentrations can be measured by either diluting the sample or using smaller sample aliquots or both. NOTE     These performance indicators are wholly dependent on the measurement regimes in individual laboratories; in particular, the detection limits are influenced by amount of stable iron present. The range of application depends on the amount of dissolved material in the water and on the performance characteristics of the measurement equipment (background count rate and counting efficiency). It is the laboratory’s responsibility to ensure the suitability of this test method for the water samples tested.

This Technical Specification describes an approach for the validation of physico-chemical analytical methods for environmental matrices.
The guidance in this document addresses two different validation approaches, in increasing order of complexity. These are:
a) method development and validation at the level of single laboratories (intra-laboratory validation);
b) method validation at the level of several laboratories (between-laboratory or inter-laboratory validation), with a focus on methods that are sufficiently mature and robust to be applied not only by a few expert laboratories but by laboratories operating at the routine level.
The concept of these two approaches is strictly hierarchical, i.e. a method shall fulfil all criteria of the first level before it can enter the validation protocol of the second level.
This Technical Specification is applicable to the validation of a broad range of quantitative physico-chemical analytical methods for the analysis of water (including surface water, groundwater, waste water, and sediment). Analytical methods for other environmental matrices, like soil, sludge, waste, and biota can be validated in the same way. It is intended either for analytical methods aiming at substances that have recently become of interest or for test methods applying recently developed technologies.
The minimal requirements that are indispensable for the characterization of the fitness for purpose of an analytical method are: selectivity, precision, bias and measurement uncertainty. The aim of validation is to prove that these requirements are met.

This document defines a methodology for determining and assessing the energy efficiency of Waste Water Treatment Plants (WWTP). The methodology aims at describing, in a systematic way, the various steps required to establish the Water Treatment Energy Index (WTEI) of a particular WWTP.
The methodology includes the classification of WWTPs in different types, identification of different stages of treatment, identification of key performance indicators (KPIs), overview of existing energy monitoring standards and the detailed description of the methodology, including a step by step guideline of how to apply and implement it.
The methodology is divided in 2 sub-methods that should be selected and followed according to the following goals:
- The Rapid Audit (RA) method allows for a quick estimation of the water treatment energy index (WTEI) based on existing information such as historical data pertaining to energy use records along with influent and effluent quality values. The aim of this methodology is to provide a WWTP energy benchmark, a rapid tool to identify energy efficiencies and inefficiencies so further actions can be planned, as well as to evaluate the impact of WWTP retrofitting.
The Rapid Audit methodology is detailed step by step in Clause 3 of this TR and can be used as a standalone document.
- The Decision Support (DS) method requires intensive monitoring across a WWTP of energy usage and water quality parameters that provides an accurate and detailed calculation of WTEI for each stage as well as its overall value for the plant. The goal of this assessment is to serve as a diagnosis of the functions/equipment in a plant that may lead to poor energy efficiency performance.
The Decision Support methodology is detailed step by step in Clause 4 of this TR and can be used as a standalone document.

This document specifies a method for the determination of certain cyclic volatile methylsiloxanes (cVMS) in environmental water samples with low density polyethylene (LDPE) as a preservative and subsequent liquid-liquid extraction with hexane containing 13C-labeled cVMS as internal standards. The extract is then analysed by gas chromatography-mass spectrometry (GC-MS). NOTE Using the 13C-labeled, chemically identical substances as internal standards with the same properties as the corresponding analytes, minimizes possible substance-specific discrimination in calibrations. Since these substances are least soluble in water, they are introduced via the extraction solvent hexane into the system.

This document specifies a method for the measurement of 210Po in all types of waters by alpha
spectrometry.
The method is applicable to test samples of supply/drinking water, rainwater, surface and ground
water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater
after proper sampling and handling, and test sample preparation. Filtration of the test sample may be
required.
The detection limit depends on the sample volume, the instrument used, the counting time, the
background count rate, the detection efficiency and the chemical yield. The method described in
this document, using currently available alpha spectrometry apparatus, has a detection limit of
approximately 5 mBq l−1, which is lower than the WHO criteria for safe consumption of drinking water
(100 mBq l−1). This value can be achieved with a counting time of 24 h for a sample volume of 500 ml.
The method described in this document is also applicable in an emergency situation.
The analysis of 210Po adsorbed to suspended matter in the sample is not covered by this method.
If suspended material has to be removed or analysed, filtration using a 0,45 μm filter is recommended.
The analysis of the insoluble fraction requires a mineralization step that is not covered by this document
[13]. In this case, the measurement is made on the different phases obtained. The final activity is the
sum of all the measured activity concentrations.
It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

This standard describes the requirements for rapid testing of water samples under emergency situations in laboratories:
- taking into account a special context for analyses, e.g. an unknown and unusual contamination;
- using or adapting if possible radioactivity measurements methods used in routine to get a result
rapidly or applying specific rapid methods previously tested by the laboratory, e.g. for 89Sr determination ;
- preparing the laboratory to analyse a large number of potentially contaminated samples.
The focus thereby is on cases where rapid radioactivity test methods are applied for all kind of waters. The first steps of the analytical strategy is often based on gross alpha and gross beta as screening methods (adaptation of ISO 10704 and ISO 11704) and gamma spectrometry (adaptation of ISO 10703). Then if necessary, specific radionuclides standards are adapted and applied (for example, Strontium 90 measurement following ISO 13160).
This guideline refers to a number of ISO standards. If appropriate, it will also refer to national or other
publically available standards.
Screening techniques that can be carried out on site are not part of this guide.

This document is focused on the structural features of rivers, on geomorphological and hydrological processes, and on river continuity. It provides guidance on the features and processes to be taken into account when characterizing and assessing the hydromorphology of rivers. It is based on methods developed, tested, and compared in Europe. Its main aim is to improve the comparability of hydromorphological assessment methods, data processing and interpretation. Although it has particular importance for the WFD by providing guidance on assessing hydromorphological quality, it has considerably wider scope for other applications. In addition, while recognizing the important influence of hydromorphology on plant and animal ecology, no attempt is made to provide guidance in this area, but where the biota have an important influence on hydromorphology these influences are included.
NOTE A case study illustrating the application of this standard is given in Gurnell and Grabowski[1].
