Improvements in monitoring and assessment

The results show that with the second RBMPs the quantity and quality of available evidence on status and pressures has grown significantly. Many Member States and River Basin Districts have invested in better or new ecological and chemical monitoring programs with more monitoring sites, more quality elements and more chemicals. Surface waters and groundwater have been monitored at over 130 000 monitoring sites over the past six years. Many more assessment methods for different quality elements have also been developed and intercalibrated[2]. This has resulted in a marked reduction of water bodies with unknown status and a clearly improved confidence in status assessment in the second RBMPs, as well as a better understanding of the status ecological, chemical and quantitative status, the pressures causing failure to achieve good status, and the needed measures.
