Directive 2006/44/EC of the European Parliament and of the Council of 6 September 2006 on the quality of fresh waters needing protection or improvement in order to support fish life (codified version) (Text with EEA relevance) (repealed)
After exit day there will be three versions of this legislation to consult for different purposes. The legislation.gov.uk version is the version that applies in the UK. The EU Version currently on EUR-lex is the version that currently applies in the EU i.e you may need this if you operate a business in the EU.
The web archive version is the official version of this legislation item as it stood on exit day before being published to legislation.gov.uk and any subsequent UK changes and effects applied. The web archive also captured associated case law and other language formats from EUR-Lex.
Version Superseded: 22/12/2013
EU Directives are being published on this site to aid cross referencing from UK legislation. After IP completion day (31 December 2020 11pm) no further amendments will be applied to this version.

In order to diminish the risk of toxicity due to non-ionised ammonia, of oxygen consumption due to nitrification and of eutrophication, the concentrations of total ammonium should not exceed the following: | |||||||||

14.Dissolved copper(mg/l Cu) | ≤ 0,04 | ≤ 0,04 | Atomic absorption spectrometry | The G-values correspond to a water hardness of 100 mg/l CaCO3 For hardness levels between 10 and 300 mg/l corresponding limit values can be found in Annex II |
It should be noted that the parametric values listed in this Annex assume that the other parameters, whether mentioned in this Annex or not, are favourable. This implies, in particular, that the concentrations of other harmful substances are very low.U.K.
Where two or more harmful substances are present in mixture, joint effects (additive, synergic or antagonistic effects) may be significant.

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
