Assessment of Motru and Motru Sec Rivers Quality by Monitoring of Physico-chemical Parameters and Water Quality Index

摘要

This paper presents a research study related to assessment of the quality status of Motru and Motru Sec rivers from measured values for physico-chemical parameters such as temperature, pH, suspended solids, nitrate, total phosphorus, dissolved oxygen and biochemical oxygen into three monitoring sections in 2012-2014. By analyzing the results obtained it can be concluded that the Motru river and its tributary, Motru Sec are included in I quality class for all parameters analyzed, except for dissolved oxygen. With respect to dissolved oxygen, the Motru river is included in class II quality for all monitored sections. The quality index value indicated that Motru river has a high status corresponding to an unpolluted river.
