The surface water status varies over time due to the many factors acting on them. These factors are produced both by human activity (anthropogenic factors) and nature (natural factors). Human activities affect water quality of surface. Under the influence of natural factors, water of surface is loaded with pollutants depending on the configuration and composition of catchment drained soils and depending on the risk produced of various hidrogeoclimatic phenomena. The Risks of water flowing surface degradation due to natural factors is appear in the high water periods and during periods of drought. In times of flood, the waters are loaded with suspensions, organic materials, metals, and other compounds containing bacteria specific from upper basin drained. In dry periods, water flows are low and significantly reduces possibilities for selfpurification. In such situations reception capabilities of pollutants are reduced and is strongly influence the state of water quality and related ecosystems. Quality status of surface water bodies depends and hydromorphological parameters and the way it was arranged the hydrographical basin. In this paper I have presented some issues regarding the quality status of the four bodies of water from some the upper sectors of major courses from Siret Hydrographical Basin where human activities are lower. The comparative study revealed that in the upper of watershed areas, anthropogenic activity is reduced and water bodies analyzed is framed within good environmental status.
