What You'll Learn
The Sarno is considered the most polluted river in Europe
The Sarno, known as Sarnus to the Romans, is a stream that passes through Pompeii to the south of the Italian city of Naples. It is considered the most polluted river in Europe. Flowing about 24 kilometres from the base of Mt. Sarno to the Bay of Naples, the river collects water from the Solofrana and Cavaiola tributaries. It is still partially used for irrigation, transportation of goods, and fishing. It is part of the Sarno river basin, which covers about 715 square kilometres.
Scientists evaluating water samples from the Sarno River say that the ecological condition of the river basin is a serious cause for concern. The complex geomorphological conditions of the basin directly impact the local environment and public health. The analysis of the available data shows how the physical aspects of the area are closely related to the distribution and concentration of pollutants, which have a significant impact on the sanitary and hygienic conditions of the local population.
The severe level of degradation of the Sarno River basin results from a combination of industrial, agrarian, and urban pollution. Industrial pollution comes from the lack of treatment of discharges from tanneries, canneries, paper, and pulp mills, printing, and textile industries. Agrarian pollution results from the unrestricted use of chemical fertilizers, phytopharmaceuticals, and herbicides.
In recent years, the Italian government has taken measures to help contain the level of pollution by mitigating or eliminating the amount of flow that enters the Sarno River. However, many environmental critics argue that this action is too little, too late.

The Danube is the second-longest river in Europe
However, the Danube now faces significant environmental challenges due to pollution. It is considered one of the most contaminated rivers in Europe, with antibiotics being a major concern. The river passes through nine countries in Central and Eastern Europe, and researchers have found up to seven different antibiotics above the safety threshold in all of these countries.
The Danube's pollution is not limited to antibiotics. In the past, the river's resources have been managed in an environmentally unsustainable manner, leading to damage from pollution, alterations to the channel, and major infrastructure development, including large hydropower dams. Overfishing and the construction of dams have also contributed to the decline of sturgeon populations in the river.
Despite these issues, the Danube still offers breathtaking landscapes and supports diverse wildlife. It is known for passing through medieval towns such as Regensburg, with its old town, stone bridge, and cathedral, and Engelhartszell, home to the only Trappist monastery in Austria. The river also flows through modern cities like Linz, European Capital of Culture in 2009, and Vienna, known for its contemporary art scene.

The Rhine flows through six countries
The Sarno River, which flows through Italy, is considered the most polluted river in Europe. However, the Danube River is also heavily polluted and flows through multiple countries.
The Rhine is another important European river, known for its industrial significance. It flows through or past six countries: Switzerland, Germany, the Netherlands, and three others. The Rhine begins in Switzerland and flows northward to the North Sea.
The Rhine is a vital waterway, providing transportation and trade connections for the regions it passes through. Like other major European rivers, it has played a significant role in defining borders and influencing trade routes. It has also contributed to cultural exchange and the rise of civilizations along its banks.
The Rhine's industrial importance has likely had an impact on the river's ecology. While the extent of pollution in the Rhine is unclear, it is worth noting that industrial activity can often lead to water contamination. The Rhine's flow through multiple countries also highlights the shared responsibility of maintaining water quality and ecological health in transnational rivers.
The Rhine's course through six countries showcases the diverse landscapes and cultural sites that it offers. From its source in Switzerland to its mouth at the North Sea, the Rhine traverses a variety of terrains and provides a means of connection and exchange for the regions it touches.

The Sarno's pollution is caused by industrial and agricultural waste
The Sarno River, known as the Sarnus to the Romans, is considered Europe's most polluted river. It rises at the base of Mt. Sarno and flows through Pompeii to the Bay of Naples, covering about 24 kilometres (15 miles). The river has served as a vital waterway in southern Italy for centuries, but today it is heavily polluted by industrial and agricultural waste.
Industrial pollution is a significant issue for the Sarno River. There are about 500 small industrial units in the area that discharge untreated wastewater into the river. This includes tanneries, canneries, paper and pulp mills, printing, and textile industries. The lack of treatment of these discharges results in toxic substances contaminating the river. Water treatment plants have been installed, but they do not operate at full capacity, leading to insufficient treatment of industrial wastewater.
Agricultural pollution is another major contributor to the degradation of the Sarno River. The unrestricted use of chemical fertilizers, phytopharmaceuticals, and herbicides in the surrounding areas has led to high levels of nutrient concentrations, especially phosphorus and nitrogen, in the river. These elevated nutrient levels have contributed to the proliferation of invasive algal species, further degrading the water quality.
The impact of the pollution in the Sarno River extends beyond the waterway itself. When flooding occurs, which is frequent in the region, the toxic river water spills onto the surrounding land, causing soil degradation. The river flows into the Gulf of Naples, posing a significant threat to the marine environment. The coast at the mouth of the river is highly degraded, and swimming is forbidden due to the high levels of toxic substances and colibacilli in the water.
The Sarno River is an important source of freshwater for the cities and towns in the region, providing water for irrigation, industry, and transportation. However, the severe pollution has led to a decline in its usability and poses a risk to human health. Efforts are being made to clean up the river, with funding allocated for dredging and the processing of sediments to remove the accumulated pollutants.

The Danube's pollution is largely due to antibiotics
The Danube is the second-longest river in Europe, flowing through ten countries and supporting diverse wildlife. However, it is now among the most contaminated rivers in Europe, largely due to antibiotic pollution.
A wide-ranging global study identified the Danube as the river with the highest concentration of antibiotics in Europe and the single most polluted river on the continent. Samples taken from the Danube in Austria contained seven antibiotics, including clarithromycin, which is used to treat respiratory tract infections such as pneumonia and bronchitis. These antibiotics were found to be nearly four times the safe level. The Danube had the highest level of antibiotic pollution among the European rivers tested, including the Thames and the Tigris.
Antibiotic pollution is a critical issue as it is a key route through which bacteria develop resistance to life-saving medicines, rendering them ineffective for human use. The inappropriate disposal of sewage and waste dumped directly into rivers, as seen in Kenya, resulted in high antibiotic concentrations of up to 100 times the safe levels, causing a total population crash of fish in the affected rivers.
The Danube's pollution is particularly concerning given its importance as a source of drinking water for approximately 20 million people. The extensive pollution of the river makes it difficult for states to clean the water, and only certain parts of Romania, where the water is cleaner, regularly obtain drinking water from the Danube.
The Danube's antibiotic pollution is largely due to its proximity to wastewater treatment systems and sewage dumps. The river's pollution is not only an environmental issue but also a public health concern, as the strengthening antibiotic resistance of environmental bacteria poses a significant threat.
