Unless otherwise specified, it applies to the total concentration of all isomers. 3 Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies. 4 This parameter is the Environmental Quality Standard expressed as a maximum allowable concentration (MAC-EQS). Where the MAC-EQS are marked as "not applicable", the AAEQS 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. 5 Unless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For substance numbered 11 (Fluoranthene), the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of Fluoranthene in fish is not appropriate. 6 This substance is not a priority substance but one of the other pollutants for which the EQS are identical to those laid down in community legislation that applied prior to Directive 2008/105/EC of the European Parliament and Council on environmental quality standards in the field of water policy. 7 DDT total comprises the sum of the isomers 1,1,1-trichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 50-29-3; EU number 200-024-3); 1,1,1-trichloro-2 (o-chlorophenyl)-2-(p-chlorophenyl) ethane (CAS number 789-02-6; EU number 212-332-5); 1,1-dichloro-2,2 bis (pchlorophenyl) ethylene (CAS number 72-55-9; EU number 200-784-6); and 1,1-dichloro-2,2 bis (p-chlorophenyl) ethane (CAS number 7254-8; EU number 200-783-0). 8 The EQS for this substance shall take effect from 22 December 2015, with the aim of achieving good surface water chemical status in relation to this substance by 22 December 2021 by means of programmes of measures included in updates of river basin management plans produced in accordance with Article 13 of the 2003 Regulations. 9 These EQS refer to bioavailable concentrations of the substances. 10 The EQS for this substance shall take effect from 22 December 2018, with the aim of achieving good surface water chemical status in relation to this substance by 22 December 2027 and preventing deterioration in the chemical status of surface water bodies in relation to this substance.

Unless otherwise specified, it applies to the total concentration of all isomers. 3 Inland surface waters encompass rivers and lakes and related artificial or heavily modified water bodies. 4 This parameter is the Environmental Quality Standard expressed as a maximum allowable concentration (EQS-MAC). 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. 5 Unless otherwise indicated, the biota EQS relate to fish. An alternative biota taxon, or another matrix, may be monitored instead, as long as the EQS applied provides an equivalent level of protection. For PAHs, the biota EQS refers to crustaceans and molluscs. For the purpose of assessing chemical status, monitoring of PAHs in fish is not appropriate. For Dioxins and dioxin-like compounds, the biota EQS relates to fish, crustaceans and molluscs, in line with section 5.3 of the Annex to Commission Regulation (EU) No. 1259/2011 of 2 December 2011 amending Regulation (EC) No. 1881/2006 as regards maximum levels for dioxins, dioxin-like PCBs and non-dioxin-like PCBs in foodstuffs (O.J. L 320, 3.12.2011, p. 18) 6 The EQS for this substance shall take effect from 22 December 2015, with the aim of achieving good surface water chemical status in relation to these substances by 22 December 2021 by means of programmes of measures included in updates of river basin management plans produced in accordance with Article 13 of the 2003 Regulations. 7 For the group of priority substances covered by brominated diphenylethers listed in Decision 2455/2001/EC, an EQS is established only for congener numbers 28, 47, 99, 100, 153 and 154. 8 For Cadmium and its compounds the EQS values vary dependent upon the hardness of the water as specified in five class categories (Class 1: 3/l, Class 2: 40 to 3/l, Class 3: 50 to 3/l, Class 4: 100 to 3/l and Class5: ≥200 mg CaCO3/l). 9 No indicative parameter is provided for this group of substances. The indicative parameter(s) must be defined through the analytical method. 10 For the group of priority substances of polyaromatic hydrocarbons (PAH), the biota EQS and corresponding AA-EQS in water refer to the concentration of benzo(a) pyrene, on the toxicity of which they are based. Benzo(a) pyrene can be considered as a marker for the other PAHs, hence only benzo(a) pyrene needs to be monitored for comparison with the biota EQS or the corresponding AA- EQS in water. 11 There is insufficient information available to set a MAC-EQS for these substances. 12 PCDD: Polychlorinated dibenzo-p-dioxins; PCDF: polychlorinated dibenzofurans; PCB-DL: dioxin-like polychlorinated biphynels; TEQ: toxic equivalents according to the World Health Organisation 2005 Toxic Equivalent Factors. 13 The EQS for this substance shall take effect from 22 December 2018, with the aim of achieving good surface water chemical status in relation to this substance by 22 December 2027 and preventing deterioration in the chemical status of surface water bodies in relation to this substance.”
