Evolución histórica de la calidad biológica del agua en la cuenca del Ebro (España) (1990-2005)

From 1990 to 2005 the Ebro River Basin has been monitored for biological water quality. The number of sampling points analysed has progressively increased along this period. The observed results show that water quality has improved with respect to the initial time of the study. In 2005, almost 80% o...

Description
Summary:From 1990 to 2005 the Ebro River Basin has been monitored for biological water quality. The number of sampling points analysed has progressively increased along this period. The observed results show that water quality has improved with respect to the initial time of the study. In 2005, almost 80% of the studied sampling stations reached a "Good" or "Very good" water quality level according to the IBMWP biotic index. In 2005 most of the sampling points had a higher IBMWP value compared to its historic mean value. Similar results were found in relation to the ecological status in 2005 in this basin when compared to the corresponding historical mean values at each sampling point.
