Resumo

Two third of the earth surface is covered by water. With a continuous growing population there is an increased presure on existing water resources. As a direct consequence oceans, rivers and other water resources are practicly sufocated by human activities with major consequences on their quality. Water pollution is a a problem of humanity which appeared early in the history. Before the 19 Century Industrial Revolution there was a nice harmony between man and nature. How bad is it? Acording to the latest estimations the chemical pollution threathens the live on earth. Every ocean and every continent from tropics to the pols is contaminated. Our work intented to asses the level of nitrate contamination in the surface waters in 7 localities (Gradinari, Forotic, Ciudanovita, Oravita, Comoraste, Calina, Racasdia,) from Caras-Severin County. The investivations took place along three years (2005-2008). Our results show a large variation of nitrates concentration and a positive correlation between analized location, rain regime and antropic activity.
