Resumen
En un estudio de caso ubicado en sectores suburbanos del área metropolitana del Valle de Lerma, en la provincia de Salta (Argentina), se evaluaron 24 sistemas de tratamiento in situ de aguas residuales (STD) con distintas configuraciones y se observaron diferencias significativas en la calidad del efluente. Para la planificación territorial de los STD, se presenta un Sistema Espacial de Apoyo a la Decisión (SEAD). Los resultados obtenidos muestran fuertes contradicciones entre nuestra zonificación y las características de urbanización actuales en el área de estudio. Como resultado, es probable que los impactos ambientales y los riesgos para la salud se manifiesten a corto o mediano plazo. Los sectores con las mejores condiciones de receptividad se encontraron en el sector sur del área de estudio. Los STD pueden implementarse de manera segura en muchas áreas siempre que este concepto esté integrado en las iniciativas de planificación urbana, que usualmente también requieren la consolidación o el desarrollo de instituciones y sistemas de control apropiados.
In a case study located in suburban sectors of the metropolitan area of the Lerma Valley, in the province of Salta (Argentina), 24 onsite wastewater treatment systems (STD) with different configurations were evaluated, and significant differences in effluent quality were observed. For territorial planning of STD, a Spatial Decision Support System (SEAD) is presented. The results obtained show strong contradictions between our zoning and the current urbanization characteristics in the study area. As a result, environmental impacts and health risks are likely to manifest in the short or medium term. The sectors with the best receptivity conditions were found in the southern sector of the study area. STD can be safely implemented in many areas as long as this concept is integrated into urban planning initiatives, which usually also require the consolidation or development of appropriate institutions and control systems.
