The surface water and groundwater watch list mechanisms aim to gather information on the presence and distribution of substances of potential concern in the aquatic environment, which, to date, have been poorly documented and for which there are often no standardised analytical methods available. In addition, for substances listed in Annex I to Directive 2006/118/EC and in Annex I to Directive 2008/105/EC, the analytical methods available on the market are not always sensitive enough to achieve the proposed quality standards. Developing new methods and monitoring an increased number of substances, groups of substances, or indicators is challenging and generates increased costs but also a need for strengthened administrative capacity in the Member States, especially those with fewer resources. Therefore, the establishment of a joint monitoring facility for managing the monitoring requirements, when so requested by the Member States, could help them in carrying out that challenging task, easing their financial and administrative burdens. The Commission should assess the options for the establishment, financing and functioning of such a monitoring facility. The use of such a facility should be voluntary, accessible to all interested Member States and without prejudice to arrangements already in place at national level.
