Aspectos preliminares de la calidad del agua del arroyo Tapalqué en la ciudad de Olavarría, provincia de Buenos Aires

In Tapalqué stream, different recreational and farming activities are developed, and on its way through Olavarría city, it receipts rainwater and sewage residues previously treated. The aim of this study is to evaluate the quality of the resource, through the determination of conventional physicoche...
