Abstract

ELORDI, María Lucila; COLMAN LERNER, Jorge Esteban  and  PORTA, Andrés. Assessment of anthropogenic impact on water quality of the stream Las Piedras, Quilmes, Buenos Aires, Argentina. Acta bioquím. clín. latinoam. [online]. 2016, vol.50, n.4, pp.669-677. ISSN 0325-2957.

The strong deterioration of surface water makes its assessment priority for proper management, including actions to control and mitigate the level of contamination and associated health risks. While each watercourse has natural characteristics and specific environmental issues, streams located on the Buenos Aires metropolitan area share some common characteristics presented in this study. To this end it is proposed to determine and evaluate the human factors that directly or indirectly affect the water quality of the river Las Piedras in Quilmes, by physico-chemical and microbiological characteristics of the water in addition to the application of quality indices (ICA) and pollution (ICOMO). By using these tools a potential and serious problem degradation of the stream and its surroundings appeared, mainly due to lack of sanitation, the discharge of wastewater without prior or inadequate treatment especially generating fecal contamination of the water, and garbage dumps and burnings at its margins, creating specific sites of contamination and spread of pests, potential infectious foci.

Keywords : Quality of surface water; Fecal contamination; Las Piedras stream.
