Where possible, without compromising disinfection, Member States shall strive for a lower value. This parameter shall be measured only if such disinfection methods are used.\nChlorite\n0,25\nmg/l\nA parametric value of 0,70 mg/l shall be applied where a disinfection method that generates chlorite, in particular chlorine dioxide, is used for disinfection of water intended for human consumption.\nWhere possible, without compromising disinfection, Member States shall strive for a lower value.\nThis parameter shall be measured only if such disinfection methods are used.\nChromium\n25\nμg/l\nThe parametric value of 25 μg/l shall be met, at the latest, by 12 January 2036. The parametric value for chromium until that date shall be 50 μg/l.\nCopper\n2,0\nmg/l\nCyanide\n50\nμg/l\n1,2-dichloroethane\n3,0\nμg/l\nEpichlorohydrin\n0,10\nμg/l\nThe parametric value of 0,10 μg/l refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water.\nFluoride\n1,5\nmg/l\nHaloacetic acids (HAAs)\n60\nμg/l\nThis parameter shall be measured only when disinfection methods that can generate HAAs are used for the disinfection of water intended for human consumption. It is the sum of the following five representative substances: monochloro-, dichloro-, and trichloro-acetic acid, and mono- and dibromo-acetic acid.\nLead\n5\nμg/l\nThe parametric value of 5 μg/l shall be met, at the latest, by 12 January 2036. The parametric value for lead until that date shall be 10 μg/l.\nAfter that date, the parametric value of 5 μg/l shall be met at least at the point of supply to the domestic distribution system.\nFor the purposes of point (b) of the first subparagraph of Article 11(2), the parametric value of 5 μg/l at the tap shall apply.\nMercury\n1,0\nμg/l\nMicrocystin-LR\n1,0\nμg/l\nThis parameter shall be measured only in the event of potential blooms in source water (increasing cyanobacterial cell density or bloom forming potential).\nNickel\n20\nμg/l\nNitrate\n50\nmg/l\nMember States shall ensure that the condition [nitrate]/50 + [nitrite]/3 ≤ 1, where the square brackets signify the concentrations in mg/l for nitrate (NO3) and nitrite (NO2), is complied with and that the parametric value of 0,10 mg/l for nitrites is complied with ex water treatment works.\nNitrite\n0,50\nmg/l\nMember States shall ensure that the condition [nitrate]/50 + [nitrite]/3 ≤ 1, where the square brackets signify the concentrations in mg/l for nitrate (NO3) and nitrite (NO2), is complied with and that the parametric value of 0,10 mg/l for nitrites is complied with ex water treatment works.\nPesticides\n0,10\nμg/l\n‘Pesticides’ means:\norganic insecticides,\norganic herbicides,\norganic fungicides,\norganic nematocides,\norganic acaricides,\norganic algicides,\norganic rodenticides\norganic slimicides,\nrelated products (inter alia, growth regulators),\nand their metabolites as defined in point (32) of Article 3 of Regulation (EC) No 1107/2009 of the European Parliament and of the Council, that are considered relevant for water intended for human consumption.\nA pesticide metabolite shall be deemed relevant for water intended for human consumption if there is reason to consider that it has intrinsic properties comparable to those of the parent substance in terms of its pesticide target activity or that either itself or its transformation products generate a health risk for consumers.\nThe parametric value of 0,10 μg/l shall apply to each individual pesticide.\nIn the case of aldrin, dieldrin, heptachlor and heptachlor epoxide, the parametric value shall be 0,030 μg/l.\nMember States shall define a guidance value to manage the presence of non-relevant metabolites of pesticides in water intended for human consumption.\nOnly pesticides which are likely to be present in a given supply need to be monitored.\nBased on the data reported by Member States, the Commission may establish a database of pesticides and their relevant metabolites taking into account their possible presence in water intended for human consumption.\nPesticides Total\n0,50\nμg/l\n‘Pesticides Total’ means the sum of all individual pesticides, as defined in the previous row, detected and quantified in the monitoring procedure.\nPFAS Total\n0,50\nμg/l\n‘PFAS Total’ means the totality of per- and polyfluoroalkyl substances.\nThis parametric value shall only apply once technical guidelines for monitoring this parameter are developed in accordance with Article 13(7). Member States may then decide to use either one or both of the parameters ‘PFAS Total’ or ‘Sum of PFAS’.\nSum of PFAS\n0,10\nμg/l\n‘Sum of PFAS’ means the sum of per- and polyfluoroalkyl substances considered a concern as regards water intended for human consumption listed in point 3 of Part B of Annex III. This is a subset of ‘PFAS Total’ substances that contain a perfluoroalkyl moiety with three or more carbons (i.e. –CnF2n–, n ≥ 3) or a perfluoroalkylether moiety with two or more carbons (i.e. –CnF2nOCmF2m–, n and m ≥ 1).\nPolycyclic aromatic hydrocarbons\n0,10\nμg/l\nSum of concentrations of the following specified compounds: benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, and indeno(1,2,3-cd)pyrene.\nSelenium\n20\nμg/l\nA parametric value of 30 μg/l shall be applied for regions where geological conditions could lead to high levels of selenium in groundwater.\nTetrachloroethene and Trichloroethene\n10\nμg/l\nThe sum of concentrations of these two parameters.\nTrihalomethanes Total\n100\nμg/l\nWhere possible, without compromising disinfection, Member States shall strive for a lower parametric value.\nIt is the sum of concentrations of the following specified compounds: chloroform, bromoform, dibromochloromethane and bromodichloromethane.\nUranium\n30\nμg/l\nVinyl chloride\n0,50\nμg/l\nThe parametric value of 0,50 μg/l refers to the residual monomer concentration in the water as calculated according to specifications of the maximum release from the corresponding polymer in contact with the water.",
