Water quality – Parameter table

This parameter shall only be measured when such disinfection methods are used.

If possible, the water suppliers responsible in cooperation with the Environmental Hygiene Service of the IP concerned (seek a lower price without affecting disinfection.

This parameter shall only be measured when such disinfection methods are used.

While the parametric value for chromium by that date is 50 μg/l, water suppliers shall take all necessary measures to achieve the new parametric value as soon as possible.

It is the sum of the following five representative substances: monochloro-, dichloro- and trichloroacetic acid, and mono- and dibromoacetic acid.

After that date, the parametric value of 5 μg/l shall be respected at least at the point of entry into the internal (domestic) distribution system.

A pesticide metabolite shall be considered relevant (critical) for water intended for human consumption if there is reason to believe that it has intrinsic properties comparable to those of the parent substance in terms of its target pesticide action or that it (or its transformation products) poses a risk to the health of consumers.

The parametric value of 0,10 μg/l applies to each individual pesticide.

For aldrin, dieldrin, heptachlor and heptachlorepoxide, the parametric value shall be 0,030 μg/l.

The Minister for Health shall establish a guidance value for the management of the presence of non-relevant (non-critical) metabolites of pesticides in water intended for human consumption, following a recommendation from the Health Committee for Pollution and Pollution of the Environment.

The above recommendation shall be issued when the National Coordinating Authority (NCA) referred to in Article 3(1) and (2) of Law 4036/2012, operating at the Ministry of Rural Development:

(a) inform the competent drinking water quality department of the Ministry of Health of the active substances in plant protection product formulations placed on the market per Regional Unit of Greece in the previous year; (b) recommend that the monitoring of specific active substances in plant protection products be included in the programmes of checks carried out on the country’s groundwater and surface water resources, as well as on the monitoring of drinking water;

recommend any appropriate measure aimed at protecting the environment and human health, as provided for in Article 19(2) and (3) of Chapter E of Joint Ministerial Decision No 9269/246316/8.9.20 on the National Action Plan referred to in Article 18 of Law 4036/2012 (Government Gazette, Series I, No 8) for the implementation of Directive 2009/128/EC of the European Parliament and of the Council of 21 October 2009 establishing a framework for Community action to achieve the sustainable use of pesticides (Government Gazette, Series II, No 309) (Government Gazette, Series II, No 4032);

Only pesticides suspected of being present in a particular water supply should be monitored.

This parametric value shall only be applied when technical guidelines for monitoring this parameter are drawn up in accordance with Article 13(7) of Directive 2020/2184/EU. A Joint Ministerial Decision of the Minister for Health and the jointly competent Ministers (Environment and Interior) will then determine whether either one or both parameters ‘Total PFAS’ or ‘Sum of PFAS’ will be monitored.

It is the sum of concentrations of the following specific compounds: chloroform, bromoform, dibromochloromethane and bromodichloromethane.

at 20 °C

For non-carbonated water placed in bottles or containers, the threshold value may be reduced to 4.5 pH units. For water put into bottles or containers with a natural content or artificially enriched with carbon dioxide, the minimum value may be lower.
