Summary:In Great San Miguel de Tucuman, Tucuman province in Argentina, a sewage network conduit an area of 3000 hectares is being built, the main piping of which will be able to deposit sewage wastes. In certain purification ponds approximately 20 hectares wich are located in the southern area of the capital city, in the El Manantial locality, on the lands typical of depressed plain. These previously treated wastes will be carried into the main river of the province of Tucuman, the Sali River, whose highly polluted waters flow into the El Frontal Dam, located on the boundary between Santiago del Estero and Tucumam provinces. During the building of the purification ponds of up to 3 m deep, the existence of volcanic ash mantles ranging from 0.20 to 0.30 m thick was observed. The latter have been serious trouble for the stabilization of the former, resulting in the percolation of sewage wastes into deep underground waters.
