- From year 2007, a new stage of adaptation to the requirements established by the Water Framework Directive begins. The control of the surface waters is carried out in accordance with the Monitoring and Control Programme that has been specified in the samplings and controls in this table.
- The numbers corresponding to Reservoirs, Wetlands and Ponds correspond to the number of points sampled in 2016. Neither the number of samples taken at each point nor the number of elements analysed in the “physico-chemical” or “biological” packages are indicated.
