The theme addressed in this work is required by its importance and timeliness given the conditions of current climate change and growing anthropogenic pressure, maintaining the quality of natural resources becomes an increasingly pressing problem. Water, as a vital and limited natural resource in space and time deserves increasing attention. To maintain water quality at acceptable levels, measures are needed to monitor and reduce the impact of human activity on water resources. One cannot conceive a human activity, the existence of a life form or the current balance of the planet we live without water. The section where samples were taken to determine the water quality of the Timiş River is Armeniş-Caransebeş. Collection sheets have been drawn up for each sample in which all relevant research information has been detailed, the collection points have been clearly marked. The depth at which the samples were collected is 0.30 m, and the collected volume is 0.5 L. The width of the water gloss and the appearance of water have been identified in the harvest. Sampling of water took place in months: February, April, May, June, July, August and September of the year 2018. The water flow was determined and analyses were made on pH, dissolved oxygen, biochemical oxygen consumption in 5 days, chemical consumption of oxygen, ammonium, nitrate, nitrogen, total nitrogen, total phosphorus and calcium. Following the analyses carried out, it was observed that the flow rate is fluctuating depending on the amount of precipitation fallen, influencing the degree of water mineralization; water is slightly basic; The oxygen regime is in optimum values, with a slight decrease in the oxygen content in July and increased biochemical and chemical oxygen consumption in April, May, June; In the nutrient regime, high levels of nitrogen, nitrogen and total nitrogen are noted, which encapsulates water in quality class II; The amount of calcium and phosphorus is low, the concentration of phosphorus analysed has no impact on water, and calcium gives water a low hardness character. In conclusion, the impact of human activities on the quality of water in the Timiş River is reduced, with small overviews only to the nitrogen regime and the oxygen content in the water. The results of the research have a high civic value and can be disseminated by local authorities in the areas studied by informing the inhabitants of the impact of anthropogenic activities on the water quality of the Timiş River and the education of the population on pollution prevention.
