Article 4 (4) to (9) of Directive 2000/60/EC shall apply *mutatis mutandis* to the substances listed in points (i) and (ii), of the first subparagraph of this paragraph.

Article 4 (4) to (9) of Directive 2000/60/EC shall also apply *mutatis mutandis* to the substances listed in points (iii) and (iv) of the first subparagraph of this paragraph. Insofar as the time extensions provided for in Article 4(4) of that Directive are concerned, they shall be limited to a maximum of one further update of the river basin management plan except in cases where the natural conditions are such that the objectives cannot be achieved within that river basin management plan period.

1b. EQS set at Union level for river basin specific pollutants in accordance with Article 16(4) of Directive 2000/60/EC and listed in Part C of Annex II to this Directive or additional river basin specific pollutants and corresponding EQS identified by Member States in accordance with Article 8d(1) of this Directive, shall take effect from the beginning of the following river basin management plan period after the date the EQS was set, with the aim of achieving good surface water chemical status in relation to those pollutants by the end of that river basin management plan period and of preventing deterioration in the chemical status of surface water bodies in relation to those pollutants.

Article 4 (4) to (9) of Directive 2000/60/EC shall apply *mutatis mutandis* to the pollutants referred to in the first subparagraph of this paragraph. Insofar as the time extensions provided for in Article 4(4) of that Directive are concerned, they shall be limited to a maximum of one further update of the river basin management plan except in cases where the natural conditions are such that the objectives cannot be achieved within that river basin management plan period.

With regard to substances other than those referred to in the first subparagraph, Member States shall apply the water EQS laid down in Part A of Annex I.

Member States that make use of the option referred to in the first subparagraph shall apply the relevant EQS laid down in Part A of Annex I or, if none is included for the matrix or biota taxon, establish an EQS that offers at least the same level of protection as the EQS laid down in Part A of Annex I.

Member States may use the option referred to in the first subparagraph only where the method of analysis used for the chosen matrix or biota taxon fulfils the minimum performance criteria laid down in Article 4 of Directive 2009/90/EC. Where those criteria are not met for any matrix, Member States shall ensure that monitoring is carried out using best available techniques not entailing excessive costs and that the method of analysis performs at least as well as that available for the matrix specified in paragraph 2 of this Article for the relevant substance.

3a. Where a potential risk to, or via, the aquatic environment from acute exposure has been identified as a result of measured or estimated environmental concentrations or emissions and where a biota or sediment EQS is being applied, Member States shall ensure that monitoring in surface water is also carried out and shall apply the MAC-EQS laid down in Part A of Annex I to this Directive where such EQS have been established.

3b. Where, pursuant to Article 5 of Directive 2009/90/EC, the calculated mean value of a measurement, when carried out using the best available technique not entailing excessive costs, is referred to as ‘less than limit of quantification’, and the limit of quantification of that technique is above the EQS, the result for the substance being measured shall not be considered for the purposes of assessing the overall chemical status of that water body.

• (a) a table presenting the limits of quantification of the methods of analysis applied, and information on the performance of those methods in relation to the minimum performance criteria laid down in Article 4 of Directive 2009/90/EC;

• (b) for the substances for which the option in paragraph 3 of this Article is used:
• (i) the reasons and basis for using that option;
• (ii) where relevant, the alternative EQS established, evidence that those EQS would offer at least the same level of protection as the EQS laid down in Part A of Annex I, including the data and methodology used to derive the EQS, and the categories of surface water to which they would apply;
• (iii) for comparison with the information referred to in point (a) of this paragraph, the limits of quantification of the methods of analysis for the matrices specified in Part A of Annex I to this Directive, including information on the performance of those methods in relation to the minimum performance criteria laid down in Article 4 of Directive 2009/90/EC;

• (c) justification for the frequency of monitoring applied in accordance with paragraph 4, if monitoring intervals are longer than one year.

5a. Member States shall take the necessary measures to ensure that the updated river basin management plans, produced in accordance with Article 13(7) of Directive 2000/60/EC, containing the results and impact of the measures taken to prevent chemical pollution of surface water, and the interim report describing progress in the implementation of the planned programme of measures in accordance with Article 15(3) of Directive 2000/60/EC, are provided through a central portal which is accessible to the public electronically in accordance with Article 7(1) of Directive 2003/4/EC of the European Parliament and of the Council of 28 January 2003 on public access to environmental information ([^E0002]).

Member States shall determine the frequency of monitoring in sediment and/or biota so as to provide sufficient data for a reliable long-term trend analysis. As a guideline, monitoring should take place every three years, unless technical knowledge and expert judgment justify another interval.

8a. In order to facilitate the implementation of this Article, technical guidelines on monitoring strategies and analytical methods for substances, including sampling and monitoring of biota, shall be developed, to the extent possible, by 22 December 2014, as part of the existing implementation process of Directive 2000/60/EC.

In particular, the guidelines shall cover:

• (a) the monitoring of substances in biota as provided for in paragraphs 2 and 3 of this Article;

• (b) in the case of newly identified substances (numbered 34 to 45 in Part A of Annex I) and substances for which stricter EQS are established (numbered 2, 5, 15, 20, 22, 23 and 28 in Part A of Annex I), analytical methods compliant with the minimum performance criteria laid down in Article 4 of Directive 2009/90/EC.

8b. In the case of substances for which technical guidelines have not been adopted by 22 December 2014, the deadline of 22 December 2015 referred to in point (i) of paragraph (1a) shall be extended to 22 December 2018, and the deadline of 22 December 2021 referred to in that point shall be extended to 22 December 2027.

Article 4

• (b) measures taken with a view to reducing the extent of the mixing zones in the future, such as those pursuant to Article 11(3)(k) of Directive 2000/60/EC or by reviewing permits referred to in Directive 2008/1/EC or prior regulations referred to in Article 11(3)(g) of Directive 2000/60/EC.

• (a) restricted to the proximity of the point of discharge;

• (b) proportionate, having regard to the concentrations of pollutants at the point of discharge and to the conditions on emissions of pollutants contained in the prior regulations, such as authorisations and/or permits, referred to in Article 11(3)(g) of Directive 2000/60/EC and any other relevant Community law, in accordance with the application of best available techniques and Article 10 of Directive 2000/60/EC, in particular after those prior regulations are reviewed.

Article 5

Inventory of emissions, discharges and losses

The first subparagraph shall not apply to emissions, discharges and losses reported by electronic means, on a yearly basis, to the Industrial Emissions Portal established under Regulation (EU) 2024/1244 of the European Parliament and of the Council ([^E0003]), in accordance with Article 7 of that Regulation.

The reference period for the establishment of values in the updated inventories shall be the year before the year in which the reviews specified in Article 5(2) of Directive 2000/60/EC are to be completed.

As part of those updates, Member States shall ensure that the point source emissions to water that do not fall under the scope of Regulation (EU) 2024/1244 or that fall below the annual reporting thresholds set out in that Regulation, as well as the emissions of pollutants from diffuse sources as defined in point (12) of Article 3 of that Regulation, to water, are also reported by electronic means to the Commission, in order to be made available in the Industrial Emissions Portal established under that Regulation, at least every six years, and aggregated at the level of each river basin district or part thereof within a Member State’s territory.

The Commission shall adopt an implementing act establishing the format of the reporting referred to in the third subparagraph of this paragraph. That implementing act shall be adopted in accordance with the examination procedure referred to in Article 9(2) of this Directive. When establishing that implementing act, the Commission shall be assisted, where so required, by the EEA.

Article 6

Transboundary pollution

• (a) the exceedance was due to a source of pollution outside its national jurisdiction;

• (b) it was unable as a result of such transboundary pollution to take effective measures to comply with the relevant EQS; and

In the case of substances falling within the scope of Regulation (EC) No 1907/2006, the Commission shall initiate, where appropriate, the procedure referred to in Articles 59, 61 or 69 of that Regulation.

In applying the provisions of the Regulations referred to in the first and second subparagraphs, Member States and the Commission shall take into account any risk evaluations and socio-economic or cost-benefit analyses required under those Regulations, including as regards the availability of alternatives.

Article 8

Review of Annexes I and II

Article 8a

Specific provisions for certain substances

In the context of future reviews of the list of pollutants in accordance with Article 16(2) of Directive 2000/60/EC, taking into account the analysis in the report referred to in the first subparagraph of this paragraph, the Commission shall consider setting a trigger value for estrogens for screening purposes and for the assessment of chemical status. Once effect-based methods are ready to use also for other substances, the Commission shall consider, in the context of future reviews, requiring Member States to use them, if necessary, at least initially in parallel with conventional analytical methods, and consider setting corresponding trigger values.

Article 8b

Watch list

The watch list shall contain a maximum of 10 substances, groups of substances, or indicators of pollution at any one time and shall indicate the monitoring matrices and the possible methods of analysis for each substance. Those monitoring matrices and methods shall not entail excessive costs for the competent authorities. The substances to be included in the watch list shall be selected from amongst the substances for which the information available indicates that they could pose a significant risk at Union level to, or via, the aquatic environment and for which monitoring data are insufficient. The watch list shall include substances of emerging concern.

On the basis of the scientific reports prepared by ECHA in accordance with paragraph 1a, the Commission shall include microplastics and appropriate indicators of the presence, evolution or transmission of antimicrobial resistance (‘indicators of antimicrobial resistance’) in the watch list, provided that methods of sampling and analysis that are reliable and do not entail excessive costs are available. By 1 December 2027, the Commission shall identify such methods of sampling and analysis.

1a. ECHA shall prepare scientific reports to assist the Commission in selecting the substances and indicators for inclusion in the watch list referred to in paragraph 1 of this Article, taking into account the following information:

• (a) Annex I to Directive 2006/118/EC of the European Parliament and of the Council (11)  and the results of the most recent review of that Annex, as well as the results of the most recent regular review of Annex I to this Directive;

• (b) the watch lists established in accordance with Directives 2006/118/EC and (EU) 2020/2184;

• (c) recommendations from the stakeholders;

• (d) Member States’ characterisation of river basin districts in accordance with Article 5 of Directive 2000/60/EC and the results of monitoring programmes established in accordance with Article 8 of that Directive;

• (e) information on production volumes, use patterns, intrinsic properties, including, where relevant, particle size, concentrations in the environment and adverse effects on human health and the aquatic environment of a substance, including information gathered in accordance with Directive 2001/83/EC, Regulation (EC) No 1907/2006, Regulation (EC) No 1272/2008 of the European Parliament and of the Council ([^E0012]), Regulation (EC) No 1107/2009, Directive 2009/128/EC, Regulation (EU) No 528/2012 and Regulation (EU) 2022/2379 of the European Parliament and of the Council ([^E0013]);

• (f) research projects and scientific publications, including information on trends and forecasts based on modelling or other predictive assessments, as well as information and data collected by remote sensing technologies, earth observation, such as Copernicus services, in situ sensors and devices or citizen science data, taking advantage of the opportunities offered by artificial intelligence, and advanced data analysis and processing;

• (g) recommendations from the working groups established under the Common Implementation Strategy for Directive 2000/60/EC;

• (h) information on emissions, discharges and losses available in the Industrial Emissions Portal under Regulation (EU) 2024/1244, as well as any additional information available on substances covered by permits under Directive 2010/75/EU.

1b. The scientific reports prepared by ECHA in accordance with paragraph 1a shall present a list of substances, groups of substances, or indicators, the recommended monitoring matrix, and an indicative method of analysis and maximum acceptable limit of quantification for each of them, with a supporting reference to scientific literature or guidance.

1c. By 1 February 2028 and every three years thereafter, ECHA shall prepare a report summarising the findings of the scientific reports prepared in accordance with paragraph 1a and shall make that report publicly available.

When updating the watch list, the Commission shall remove any substance or indicator from the watch list for which a risk-based assessment as referred to in Article 16(2) of Directive 2000/60/EC can be conducted without additional monitoring data. However, an individual substance, group of substances, or indicator may be kept on the watch list for another period of maximum three years where additional monitoring data are needed to assess the risk to the aquatic environment.

Each updated watch list shall also include one or more additional substances, groups of substances, or indicators for which the Commission considers, on the basis of the scientific reports of ECHA, that there could be a widespread risk to or via the aquatic environment, subject to the updated watch list containing a maximum of 10 substances, groups of substances, or indicators, in accordance with paragraph 1.

Microplastics and indicators of antimicrobial resistance shall not be kept on the list for a second consecutive period of three years unless a harmonised and reliable risk assessment methodology is available which, when applied, shows that the monitoring data collected during the first monitoring period are insufficient to assess the risk they pose to or via the aquatic environment.

Each Member State shall select at least one monitoring station, plus one station if it has more than one million inhabitants, plus the number of stations equal to its geographical area in km² divided by 60 000 , rounded to the nearest integer, plus the number of stations equal to its population divided by five million, rounded to the nearest integer.

In selecting the representative monitoring stations, the monitoring frequency and the timing for each substance, group of substances, or indicator, Member States shall take into account seasonal variability in rainfall, water levels, use patterns and the possibility of the substance, group of substances, or indicator occurring. The frequency of monitoring shall be no less than twice per year when carried out in water and no less than once per year when carried out in sediment or biota. When higher frequencies are required, as for substances that are sensitive to climatic or seasonal variabilities, the increase in frequency shall be set out and technically justified in the implementing act establishing the watch list adopted pursuant to paragraph 1.

Where a Member State is in a position to generate and provide the Commission with sufficient, comparable, representative and recent monitoring data for a particular substance, group of substances, or indicator from existing monitoring programmes or studies, it may decide not to undertake additional monitoring under the watch list mechanism for that substance, group of substances, or indicator, provided that the substance, group of substances, or indicator was monitored using a methodology that is compliant with the monitoring matrices and the methods of analysis referred to in the implementing act establishing the watch list, as well as with Commission Directive 2009/90/EC ([^E0014]).

Where the Commission, having regard to the assessment by ECHA referred to in the first subparagraph of this paragraph, concludes that no further monitoring is required to further assess the risk to the aquatic environment, this assessment by ECHA shall be taken into account in the review of the lists of substances in Annex I or Part C of Annex II to this Directive, in accordance with Article 16 of Directive 2000/60/EC.

Article 8c

Specific provisions for pharmaceutical substances

Pursuant to Article 16(9) of Directive 2000/60/EC, and where appropriate on the basis of the outcome of its 2013 study on the risks posed by medicinal products in the environment and of other relevant studies and reports, the Commission shall, as far as possible within two years from 13 September 2013 develop a strategic approach to pollution of water by pharmaceutical substances. That strategic approach shall, where appropriate, include proposals enabling, to the extent necessary, the environmental impacts of medicines to be taken into account more effectively in the procedure for placing medicinal products on the market. In the framework of that strategic approach, the Commission shall, where appropriate, by 14 September 2017 propose measures to be taken at Union and/or Member State level, as appropriate, to address the possible environmental impacts of pharmaceutical substances, particularly those referred to in Article 8b(1), with a view to reducing discharges, emissions and losses of such substances into the aquatic environment, taking into account public health needs and the cost-effectiveness of the measures proposed.

Article 8d

River basin specific pollutants

By 22 December 2027, Member States shall inform the Commission of their list of river basin specific pollutants and EQS set pursuant to the first subparagraph of this paragraph. The Commission shall ensure that that information is made publicly available.

Subsequent updates of the list of river basin specific pollutants identified by the Member States in accordance with the first subparagraph of this paragraph and their corresponding EQS shall be included in the river basin management plans to be produced under Article 13 of Directive 2000/60/EC.

Article 9

CAS: Chemical Abstracts Service.

EU number: European Inventory of Existing Commercial Substances (EINECS) or European List of Notified Chemical Substances (ELINCS).

This parameter is the EQS expressed as an annual average value (AA-EQS). Unless otherwise specified, it applies to the total concentration of all substances and isomers.

Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies.

This parameter is the EQS expressed as a maximum allowable concentration (MAC EQS). Unless otherwise specified, it applies to the total concentration of all substances and isomers. Where the MAC EQS are marked as ‘not applicable’, the AA EQS values are considered protective against short-term pollution peaks in continuous discharges since they are significantly lower than the values derived on the basis of acute toxicity.

If an EQS for biota or sediment is given, it, rather than the water EQS, shall be applied, without prejudice to Article 3(3) of this Directive allowing an alternative biota taxon, or another matrix, to be monitored instead, as long as the EQS applied provides an equivalent level of protection. Unless otherwise specified, it applies to the total concentration of all substances and isomers. Unless otherwise indicated, the biota EQS relate to fish. ‘fw fish’ indicates the biota EQS for freshwater fish monitored in inland waters; ‘sw fish’ indicates the biota EQS for saltwater fish monitored in other surface waters. For substances numbered 15 (Fluoranthene), 28 (PAHs), and 51 (Bisphenol-A) the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene PAHs, and Bisphenol-A in fish is not appropriate. For substance number 37 (Dioxins and dioxin-like compounds), the biota EQS relates to fish, crustaceans and molluscs, in line with point 4.1.5 of Annex I to Commission Regulation (EU) 2023/915 (*).

For the group of priority substances covered by brominated diphenylethers (No 5), the EQS refer to the sum of the concentrations of congener numbers 28, 47, 99, 100, 153 and 154.

Tetra, Penta, Hexa, Hepta, Octa and Decabromodiphenylether (CAS numbers 40088-47-9, 32534-81-9, 36483-60-0, 68928-80-3, 32536-52-0, 1163-19-5, respectively).

For Cadmium and its compounds (No 6) the EQS values vary depending on the hardness of the water as specified in five class categories (Class 1: < 40 mg CaCO3/l, Class 2: 40 to < 50 mg CaCO3/l, Class 3: 50 to < 100 mg CaCO3/l, Class 4: 100 to < 200 mg CaCO3/l and Class 5: ≥ 200 mg CaCO3/l).

No indicative parameter is provided for this group of substances. The indicative parameter(s) shall be defined through the analytical method.

DDT total comprises the sum of the isomers 1,1,1 trichloro 2,2 bis (p chlorophenyl) ethane (CAS 50 29 3, EU 200 024 3); 1,1,1 trichloro 2 (o chlorophenyl) 2 (p chlorophenyl) ethane (CAS 789 02 6, EU 212 332 5); 1,1-dichloro 2,2 bis (p chlorophenyl) ethylene (CAS 72 55 9, EU 200 784 6); and 1,1 dichloro 2,2 bis (p chlorophenyl) ethane (CAS 72 54 8, EU 200 783 0).

These EQS refer to bioavailable concentrations of the substances.

Nonylphenol (CAS 25154-52-3, EU 246-672-0) including isomers 4-nonylphenol (CAS 104-40-5, EU 203-199-4) and 4-nonylphenol (branched) (CAS 84852-15-3, EU 284-325-5).

Octylphenol (CAS 1806-26-4, EU 217-302-5) including isomer 4-(1,1’,3,3’-tetramethylbutyl)-phenol (CAS 140-66-9, EU 205-426-2).

Benzo(a)pyrene (CAS 50-32-8) (RPF 1), benzo(b)fluoranthene (CAS 205-99-2) (RPF 0,1 ), benzo(k)fluoranthene (CAS 207-08-9) (RPF 0,1 ), benzo(g,h,i)perylene (CAS 191-24-2) (RPF 0), indeno(1,2,3-cd)pyrene (CAS 193-39-5) (RPF 0,1 ), chrysene (CAS 218-01-9) (RPF 0,01 ), benzo(a)anthracene (CAS 56-55-3) (RPF 0,1 ), dibenz(a,h)anthracene (CAS 53-70-3) (RPF 1) and fluoranthene (CAS 206-44-0) (RPF 0,01 ). Fluoranthene also appears separately in row 15. The PAHs anthracene and naphthalene are listed only separately because no RPF is available.
