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.
