CONSIDERATIONS ON THE EVOLUTION OF THE ŞOMUZU MARE RIVER WATER QUALITY IN THE DOLHEŞTI MONITORING SECTION
Abstract
Considerations On The Evolution Of The Şomuzu Mare River Water Quality In The Dolheşti Monitoring Section. The paper deals with changes in indicators of quality physical - chemical, selected to present the main environmental impact of existing pressures in the river Siret. The main sources of pollution in the Siret basin are ranked according to: the impact of the pollutant toxicity and the maximum permissible value set for the evacuated pollutants. The study looked at water quality monitoring Siret River and it’s tributaries in different sections of the monitoring study period was from 2009 to 2010. Based on the monitoring indicators agreed levels, grade falls into water courses. For knowing the quality of water flowing from the Siret River Basin during the years 2009 and 2010 were collected from river water samples Şomuzu Mare Dolheşti city. The main sources of pollution in the catchment area have influenced the state of its river water quality. After analyzing the variation in quality indicators increased physical - chemical river water quality Şomuzu Mare Dolheşti monitoring section in 2010, decreased compared with 2009, due to nitrite indicator, inducing a weak class quality Şomuzu Mare River , falling in the fourth grade of quality. Objectives and guidelines for water management strategy of the Siret River Basin aimed at achieving good water quality status, as required by the WFD.
