<s>[INST] The next text is a question of a member of the European parliament:"The Segura is a river which flows through the Spanish autonomous communities of Castilla la Mancha, Murcia and Valencia. By the time it reaches the sea (at Vega Baja, in the Valencia region) its waters are highly polluted, which has an adverse effect on the environment, agriculture and the quality of life of the above locality, which is situated in the province of Alacant, in the southern part of the Valencia region.  The Commission has drawn up a directive which requires all the EU Member States to clean up their rivers by the year 2006. To do this they must ensure that an ecological flow rate of 4000 litres per second is maintained and they must extend and improve the operation of water treatment plants.  Environmental experts fear that the current pollution levels in the Segura river and the lack of appropriate installations will make it difficult for the Community directives to be complied with.  Is the Commission aware of the worrying levels of pollution in the river Segura? What action is the Commission intending to take to ensure compliance with the relevant environmental laws within the prescribed period (i.e. by 2006)?"
