Pollution in the Douro estuary. Researchers warn of “pitiful” condition.

There are boats on the Douro River that are making illegal discharges and there is no one controlling them. They are identified as one of the causes of river pollution.

But for environmentalists and researchers, this is just one of many problems. There are 22 thousand houses or commercial spaces with direct or indirect sewage to the Douro estuary.

There are more cruises on the Douro but not all of them treat water

Guardianship guarantees its own residual station on Portuguese hotel ships, but not on foreign ones. Captaincy issued five notices. Waste collected by tanker trucks is dumped into the sewer system.

In the first half of this year alone, there were 11,322 trips on the Douro River, including hotel ships, day cruises or pleasure boats. There are 132 more than registered last year. And, although the Ministry of Economy and the Sea guarantees, to JN, that “hotel ships flying the Portuguese flag all have their own wastewater or sewage treatment system”, the same cannot be said about foreign cruises operating in the Douro. António Costa Silva's office says that they are certified "as local auxiliary vessels", but the "construction process does not pass through Portugal", not ensuring that they have a similar system.

Pollution levels of the Ave River above those recommended by the EU

ICBAS researchers warn of the impact of pollution caused by farming in the Ave river basin.

A study of the Instituto de Ciências Biomédicas Abel Salazar of the University of Porto (ICBAS-UP), part of the ATLANTIDA Project (financed by the European Regional Development Fund (ERDF) through the NORTE 2020 Program), and recently published in the journal Marine Pollution Bulletin, demonstrated that the use of pesticides from agricultural practices still has a significant negative impact on the Ave river.

What was, about 30 years ago, one of the most polluted rivers in the country and in Europe, the result of discharges from the textile industry characteristic of that region, continues today to face problems related to the pollution caused by the agricultural exploitation located in its hydrographic basin.

For Maria João Rocha, responsible for the study, these results are very relevant, in the sense that pollution in the Ave River is associated with the presence of industries, often forgetting that the effluents also come from agricultural areas.
