EVALUATION OF HEAVY CONTAMINATION AROUND BUENOS AIRES CITY
A Shanty Town called “Villa 20” and “Pope Francisco” was subject to clean up work by Green Cross in Argentina. The area is heavily contaminated due to the presence of a 7,000-square-metre car cemetery. Leakage of fuel and oil, as well as cadmium, lead and heavy metals in general, has been extensive. Local children suffer particularly from lead contamination and the ground water is undrinkable due to these toxic elements. Green Cross Argentina determined the levels of contamination and the size of the most affected area using georadar, geoelectric devices, Georesistance determination, electromagnetometers and other specific devices, and proposed a remediation plan to the Government of the City of Buenos Aires as well as the Ombudsman. Laboratory sampling of land and water was also taken in several places and at different depths.
