Abstract:	The species of Ephemeroptera as well as Plecoptera can be used as a bioindicator group in the evolution of the flowing water quality, du to their increased sensitivity to the anthropic pressure. In most cases, the zoobenthic communities respond to the action of disturbances by re-adjusting their specific composition and numerical abundance, respectively by changing the spatial distribution of the most taxons (Relyea and colab, 2000; Tudorancea & Tudorancea, 2002; Tudorancea, 2004). The diversity of the fauna of ephemeroptera and plecoptera undergoes important changes for the stations located especially downriver from the industrial centers within the Baia Mare industrial surroundings, thus the most affected stations, in the decreasing order of the intensity of the impact, are Valea Firiza, downriver of Baia Mare, upriver of Baia Mare, and downriver of Baia Sprie.
