The use of macroinvertebrates as indicators water quality is an effective and low-cost tool, which widely implemented in biomonitoring programmes. Certain taxa are characteristic impaired watercourses (e.g. Oligochaeta, Chironomidae Amphipoda), while others good-quality Ephemeroptera, Plecoptera Trichoptera; EPT). In this work, we evaluated the response macroinvertebrate assemblages to differen...
