The “Xup Riera Viva” project, together with the Parc de la Sèquia, organized a day of biological and biochemical inspection of the health status of the Rajadell stream in Xup, where neighborhood families were attended. This year, as a novelty, the workshop had a binocular magnifying glass that allowed attendees to be able to see in detail and identify the bodies that live in the water. The workshop also analyzed the state of good water quality. These days are carried out from the beginning of the project “Xup Riera Viva” and aim to make a collection of data to see what is the state of conservation of this natural environment.
