May 02, 2011
Own Xunta is aware that an important part of the Galician coastal waters does not meet the minimum standards of quality. For the first time in 2010 the Ministry of the environment launched a network of control of dangerous substances in coastal waters. Technicians hired by the Department led by Agustín Hernández samples taken in the estuaries, analyzing separately those areas close to the ports and waters of transition, i.e., the areas in the mouths of the rivers, as said it an Ombudsman of the Galician Government.
The diagnosis was that they were a "bad chemical state" areas opposite Vigo and Moaña, in the RIA of Vigo. Contamination on the coast of Marin was also detected. In A Coruña coastal waters of Corcubión, Bens, A Coruña and Ares violate environmental norms. The area of A Mariña nor passed the sieve.
Between ports, samples reveal that Vigo, Marín and Ferrol have rates of chemical substances over the environmental values set by the EU.
Substances
The analytical reflect that these areas have high levels of metals such as lead, mercury or cadmium as well as substances as the benzo perileno or benzo fluoranteno, which are hydrocarbons.
Poor cleansing of waste water is one of the main causes of pollution of the Galician rias, and could also leave him very expensive to the competent authorities. In Vigo the sewage treatment plant to be built in Lagares (currently are already in competition the project and the work) will help to curb the fine of 20 million of the EU by pollution of shellfish. However, this penalty was joined last April a judgment of the Community Court of Justice condemning the Spanish State for violating the directive on the treatment of urban wastewater in Vigo and other eight woman of Galicia (A Coruña)(Santiago, Baiona, Tui, Noia, Ribeira, affection and Viveiro).
