Evolució dels nitrats analitzats a l'aigua de 87 fonts situades en 28 municipis de la comarca d'Osona

La comarca d’Osona ha disposat sempre d’aigua abundant i de bona qualitat, però en els darrers anys s’ha observat un increment del contingut de nitrats a les aigües subterrànies. Des de 1988 i fins a l’actualitat es mostreja puntualment l’aigua d’algunes fonts i se n’analitzen els nitrats. En aquest estudi s’analitza l’evolució del contingut de nitrats i com ha afectat a la mineralització de l’aigua d’aquestes fonts i en quin estat es troben actualment. La legislació actual (RD 140/2003) considera que valors de nitrats a l’aigua de consum superiors a 50 mg/l poden provocar problemes de salut pública.
