摘要：The entire mine activity has negative effects, among which we mention the impurification of flowing surface and phreatic waters. The supply source of aquaeous horizons from Gârla Quarry is represented by the atmospheric precipitations and infiltration waters, especially those coming from Jiu river. This paper presents the influence of waters discharged from Gârla Quarry on Jiu river. Physical and chemical indicators were monitored: pH, fixed residue, suspension, sulphates, calcium, magnesium, total ferrum using the experimental methods provided by STAS. The influence of the mining activity at Gârla Quarry on the quality of surface waters is not significant but it is major on the status of underground waters.
