Romanian farmers should use less chemical fertilisers and pesticides, and local authorities should improve the ways of treating waste water from agriculture by developing investment projects as the content of nitrates and phosphorus is high, particularly in the areas of big urban settlements, recent monitoring reports of the Romanian Waters National Administration indicate.
ANAR statistics drawn up in 2004-2007 reveal that in the case of ungrounded waters high contents of nitrates were recorded in the plain areas (the Romanian Plain, the Western Plain), and less so in hilly areas (the Moldavian Hills, the Transylvanian Hills).
In the case of streams, high contents of nitrates were recorded on the sections of low-flow streams in the Romanian Plain and the province of Dobrogea.
Although the content of nitrates does not exceed the 50 mg/l level, eutrophication is recorded particularly because of high temperature of waters and low speed, in 50% of the sections under monitoring, on lakes, particularly in the Romanian Plain and the province of Dobrogea, but also on the Black Sea sections under monitoring, especially in summertime.
There are multiple cases having led to nitrate pollution. Contributing to the pollution of underground waters has been the lack of waste water collection systems in human settlements, historic sources (animal farms having closed down or reduced business), agricultural activities (incorrect storage of manure and incorrect animal breeding, incorrect use of chemical and organic fertilisers), communal and industrial waste landfills inadequately secured, industrial facilities and platforms, which contribute to the pollution of undergrounds waters because of the storage of raw material, finished and ancillary products.
The causes for the pollution of ground waters include the lack of waste water cleaning stations, industrial sources, including animal farms, particularly facilities covered by the integrated pollution prevention and control directive (91/61/EC) which have been extended derogations, as well as incorrect use of chemical and organic fertilisers.
At the same time, the state of Romania’s coastal waters depends to a great extent on the quality of the Danube waters, given that this river is a major contributor of nutrients, as it collects 801,463 square km of water, covering the territory of 19 countries, in whole or in part.
The EU directives related to water management require that three-step cleaning stations be set up, particularly in big towns and cities, in order to achieve the water quality standards in force.
ANAR reports indicate that there is currently no such station in Romania able to treat wastewater of phosphorus and nitrates.
The year 2010 is the first deadline for Romania reporting on the implementation of the European directive. It is the year in which some of the large urban settlements in excess of 100,000 people (Cluj-Napoca, Iasi, Alba-Iulia, Pitesti, Constanta, Eforie Nord, Galati, Targu Mures, Ploiesti and Timisoara) have to complete works on three-step water treatment stations and connect the local to them.
There are currently 397 water treatment stations, 14 with finalised mechanical and biological steps for settlements of between 2,000 and 10,000 people.
Out of the total stations, 18 reports connection rates in excess of 95% – the ones in Cluj-Napoca, Constanta, Sibiu, Bistrita, Victoria, Slobozia, Urziceni, Tandareni, Fieni, Stei, Sebes-Petresti, Plopeni.
Officials of European water management organisations say farm pollution in the most serious problem facing most of European countries in the area of water management, and particularly Romania.
