The landfill location is presented in Figure 1. Microwave assisted acid digestion of aqueous samples and extracts. SardiniaFourteenth International Waste Management and Landfill Symposium These results are consistent with many other studies on transport and retention of metals in tropical soil Boscov, Serra Geral Formation comprises a set of basaltic rocks originated from volcanic flows which are intercalated with eolian fine-grained sandstone deposits.
Results showed that the tropical sandy soil that composed the landfill foundation retained the investigated metals, so that their concentrations did not exceed limit acceptable values of soil contamination from the state of Sao Paulo. Table 3 — Metal concentration in the natural soil background and leachate sludge.
This landfill, which activities started inwas inadequately operated from the beginning untilwhen a reclamation plan was implemented to turn it into a sanitary lanfill. After the pond was emptied, it was observed that the bottom had low bearing capacity, what turned the security of the probing team difficult to guarantee both in terms of accessibility to the pond and subsoil sampling.
I’ll be really geofecnia grateful. The samples were cubic with side length of 0.
Contaminated soil sampling Samples of contaminated soil were collected at three profiles located inside the area of the former leachate pond at 6 depths: Enter the email address you signed up with and we’ll email you a reset link. Since the end of last century, waste disposal in dumps – sites which receive wastes without any environmental protection – became inadmissible in several countries.
No registered users and 9 guests. The vessel was sealed and heated in a pre-defined sequence in the microwave: For each round of microwave heating one vessel containing only 10 mL of nitric acid was used as a blank test.
This paper presents the exhumation geotecmia contaminated soil samples under an unlined leachate lagoon located in Botucatu Municipal Landfill and the results of chemical analyses to determine metal contamination in the site.
X-ray fluorescence semi-quantitative analysis ammbiental predominance of Si, Al e Fe, compatible to the mineralogical composition. Soil samples were collected in three profiles located inside the area of the leachate pond at 6 depths ranging from the subsoil surface until 4- m depth.

A soil sample of 0. For all the analyzed chemical elements, the concentrations in the subsoil range between the concentrations of the soil background uncontaminated natural soil and of the leachate sludge, except for isolated two values of arsenic concentration. Figure 2 View of the unlined leachate pond. Datos del sector y tipo de proyecto 4.
The unlined leachate pond was deactivated and emptied after a new lined pond was built. Thank you very much.

Remember me on this computer. As observed by Ferrari et al. Who could help me?
This opportunity was taken to collect samples of the subsoil under the pond area to assess the contamination profile. Help Center Find new research papers in: Soil characterization Geotechnical characterization of the local soil is presented in Table 1.
Sampling operations had geohecnia be changed Figure 5 the profiles had to be relocated. Transporte de poluentes em solos — SardiniaFourteenth International Waste Management and Landfill Symposium Figure 8 – Lead concentration in the subsoil underneath the leachate pond.
Other results of chemical analysis of the local soil are presented in Table 2.
