The Bilbao Bizkaia Water Consortium, the UPV/EHU, Gaiker and Cadagua start up the emerGEN project on resistant bacteria and emergent contaminants

The research, which will last for two years, has a budget of €488,062, financed by the Bilbao Bizkaia Water Consortium within the Collaboration Framework Agreement with the UPV/EHU to contribute to strengthening scientific and technological research and innovation in the field of water management.  The goal is the detection and treatment of emerging contaminants, bacteria, and antibiotic-resistant genes, as well as the use of biological effect measurement tools (bioassays) in supply waters in Bizkaia. Passive sampling techniques will be combined with chemical and biological analyses.
