Lima river estuary, Portugal
The Lima River Estuary, the end member of an international watershed in NW Portugal, receives diffuse pollution from agriculture, untreated urban and industrial wastewater. Several micropollutants have been detected in the estuarine sediments and surface water, which can generate a risk if transported to the aquifer. During tides, salt intrusion extends up to 20 km upstream from the river mouth, which can limit the possibility to use water for irrigation or drinking water production. Extreme weather events can also cause relevant erosion problems
