RODRIGUEZ-ALVAREZ, María S; MORANA, Liliana B; SALUSSO, María M y SEGHEZZO, Lucas. Spatial and seasonal characterization of the drinking water from various sources in a peri-urban town of Salta. Rev. argent. microbiol. [online]. 2017, vol.49, n.4, pp.366-376. ISSN 0325-7541. http://dx.doi.org/10.1016/j.ram.2017.03.006.
Drinking water monitoring plans are important to characterize both treated and untreated water used for drinking purposes. Access to drinking water increased in recent years as a response to the Millennium Development Goals set for 2015. The new Sustainable Development Goals aim to ensure universal access to safe drinking water by 2030. Within the framework of these global goals, it is crucial to monitor local drinking water systems. In this paper, treated and untreated water from different sources currently consumed in a specific town in Salta, northern Argentina, was thoroughly assessed. Monitoring extended along several seasons and included the physical, chemical and microbiological variables recommended by the Argentine Food Code. On the one hand, treated water mostly complies with these standards, with some non-compliances detected during the rainy season. Untreated water, on the other hand, never meets microbiological standards and is unfit for human consumption. Monitoring seems essential to detect anomalies and help guarantee a constant provision of safe drinking water. New treatment plants are urgently needed to expand the water grid to the entire population.
