Under current conditions, the water resource at planetary level has become increasingly expensive because of human pressure. Therefore, maintaining drinking water quality is increasingly important. In this paper, the authors present the influence of human activities on the River Somes (Romania). It has been studied mainly as water quality indices. Within the Somes-Tisa basin, the authors identified 41 potentially polluting industrial sources in the following fields of activity: mining (decantation ponds, mining dumps) and urban and industrial waste management. Thus, the authors analysed the best pollution parameters such as pH, dissolved oxygen, biochemical oxygen consumption, ammonia, nitrates, nitrites, total nitrogen, chromium, calcium, and magnesium. As a result of effected analyses, it can be observed a charge of nitrites and chlorides, and the presence of pollution phenomenon is showed by the high values of nitrites and biochemical oxygen consumption. Analyses were carried out over three years, 2014-2016. Quality classes increased from 2014 to 2016 because pollution decreased due to the lack of connection of the households to the waste water system in 2013-2014. Research analyses show that the water from the River Somes tends to maintain its quality; however, surface waters tend to be polluted and they are slightly influenced by human activities.
