Effects of growing and uncontrolled urbanization in the northern region of Salta and Vaqueros in Argentina
The city of Salta and the municipality of Vaqueros have shown a significant demographic growth over the last fewdecades, a growth that constitutes a threat to the region’s quality of water. By means of analyzing current existingdata, the article illustrates the effect that recent and uncontrolled ur...

By means of analyzing current existingdata, the article illustrates the effect that recent and uncontrolled urbanization has had on microbiological, physical and chemical quality of subterranean water through time. Accordingly, the variables selected were the presence of pathogenic microorganisms (coliform bacteria) and nitrate concentration in water, the latter being the most frequent pollutant of underground aquifers. It concludes that the relation between the increase of nitrate concentration and population growth is due to contamination caused by septic tanks, hence, the implementation of sewer systems and water treatment plants should be considered promptly, as well as a thorough land usage plan to control the growth of urban areas in the regionfocus of this study. La ciudad de Salta y el municipio de Vaqueros han registrado un notable crecimiento demográfico en las últimas décadas, lo que constituye una amenaza para la calidad del agua de la región. El artículo determina mediante datos existentes, el efecto que a través del tiempo provocó la urbanización creciente y descontrolada sobre la calidad físico-química y microbiológica del agua subterránea. Las variables seleccionadas para ello fueron la presencia de microorganismos patógenos (bacterias coliformes) y la concentración de nitratos que se considera el contaminante más común en el agua subterránea. Se concluye existe una relación entre aumento de la población e incremento de la concentración de nitratos, debido a que la fuente principal de la contaminación son los tanques sépticos. Por lo tanto, debe considerarse cuidadosamente la necesidad de implementar sistemas de alcantarillado sanitario y plantas de tratamiento. Se hace urgente una planificación del uso del suelo que oriente el crecimiento urbano en el área de estudio.
