Article 8b 3.

Member States shall monitor each substance, group of substances, and indicator on the watch list referred to in paragraph 1 at selected representative monitoring stations over a 24-month period. The monitoring period shall commence within six months of the inclusion of the substance in the list, but sampling and analysis need not commence at the start of that period.

Each Member State shall select at least one monitoring station, plus one station if it has more than one million inhabitants, plus the number of stations equal to its geographical area in km2 divided by 60 000 , rounded to the nearest integer, plus the number of stations equal to its population divided by five million, rounded to the nearest integer.

In selecting the representative monitoring stations, the monitoring frequency and the timing for each substance, group of substances, or indicator, Member States shall take into account seasonal variability in rainfall, water levels, use patterns and the possibility of the substance, group of substances, or indicator occurring. The frequency of monitoring shall be no less than twice per year when carried out in water and no less than once per year when carried out in sediment or biota. When higher frequencies are required, as for substances that are sensitive to climatic or seasonal variabilities, the increase in frequency shall be set out and technically justified in the implementing act establishing the watch list adopted pursuant to paragraph 1.

Where a Member State is in a position to generate and provide the Commission with sufficient, comparable, representative and recent monitoring data for a particular substance, group of substances, or indicator from existing monitoring programmes or studies, it may decide not to undertake additional monitoring under the watch list mechanism for that substance, group of substances, or indicator, provided that the substance, group of substances, or indicator was monitored using a methodology that is compliant with the monitoring matrices and the methods of analysis referred to in the implementing act establishing the watch list, as well as with Commission Directive 2009/90/EC ( 14 ).
