Sistema aquífero grande Amazônia : um estudo sobre a composição química das águas das cidades de Itacoatira e Manacapuru-AM

Abstract

Water is a common good. There is no life without water. In a society that grows exponentially one can already notice some countries with shortages of liquid. Many regions of the planet devoid of surface sources dig its technical and legal criteria which causes serious public health problems. This is clearer in developing countries like those in Africa and Latin America. The main chemical contaminant in groundwater is nitrate that can even lead to cancer. The contamination for nitrate is not the privilege of poor countries. Europe, North America and Oceania also suffer from the effects of pollution originating from agriculture which shows that contamination by nitrate is a global problem.
