composition — the chemical composition of a metal, enamel, ceramic or other inorganic material (11)

domestic distribution system — the pipework, fittings and appliances which are installed between the taps that are normally used for water intended for human consumption in both public and private premises and the distribution network, but only if they are not the responsibility of the water supplier, in its capacity as a water supplier, under the relevant national law (2)

food business — borrowed from another act; this instrument states no meaning of its own (5)

food business operator — borrowed from another act; this instrument states no meaning of its own (6)

hazard — a biological, chemical, physical or radiological agent in water, or another aspect of the condition of water, with the potential to cause harm to human health (7)

hazardous event — an event that introduces hazards into, or fails to remove them from, the supply system of water intended for human consumption (8)

Pesticides — organic insecticides, organic herbicides, organic fungicides, organic nematocides, organic acaricides, organic algicides, organic rodenticides organic slimicides, related products (inter alia, growth regulators), and 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. A 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. The parametric value of 0,10 μg/l shall apply to each individual pesticide. In the case of aldrin, dieldrin, heptachlor and heptachlor epoxide, the parametric value shall be 0,030 μg/l. Member States shall define a guidance value to manage the presence of non-relevant metabolites of pesticides in water intended for human consumption. Only pesticides which are likely to be present in a given supply need to be monitored. Based on the data… ANNEX I

Pesticides Total — the sum of all individual pesticides, as defined in the previous row, detected and quantified in the monitoring procedure. PFAS Total 0,50 μg/l ANNEX I

PFAS Total — the totality of per- and polyfluoroalkyl substances. This 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’. Sum of PFAS 0,10 μg/l ANNEX I

priority premises — large non-household premises with many users potentially exposed to water-related risks, in particular large premises for public use, as identified by Member States (4)

risk — a combination of the likelihood of a hazardous event and the severity of the consequences if the hazard and hazardous event occur in the supply system of water intended for human consumption (9)

starting substance — a substance that has been intentionally added in the production of organic materials or of admixtures for cementitious materials (10)

Sum of PFAS — 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). Polycyclic aromatic hydrocarbons 0,10 μg/l Sum of concentrations of the following specified compounds: benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(ghi)perylene, and indeno(1,2,3-cd)pyrene. Selenium 20 μg/l A parametric value of 30 μg/l shall be applied for regions where geological conditions could lead to high levels of selenium in groundwater. Tetrachloroethene and Trichloroethene 10 μg/l The sum of concentrations of these two parameters. Trihalomethanes Total 100 μg/l Where possible, without compromising disinfection, Member States shall strive for a lower parametric value. It is the sum of concentrations of the following specified compounds: chloroform, bromoform, dibromochloromethane and bromodichloromethane. Uranium 30 μg/l Vinyl chloride 0,50 μg/l The parametric value of 0,50 μg/l refers to the… ANNEX I

water intended for human consumption — all water, either in its original state or after treatment, intended for drinking, cooking, food preparation or other domestic purposes in both public and private premises, regardless of its origin and whether it is supplied from a distribution network, supplied from a tanker or put into bottles or containers, including spring waters; all water used in any food business for the manufacture, processing, preservation or marketing of products or substances intended for human consumption (1)

water supplier — an entity supplying water intended for human consumption (3)
