X-ray fluorescence semi-quantitative analysis showed predominance of Si, Al e Fe, compatible to the mineralogical composition. The planned location of the boreholes is presented as red points in Bboscov 4. The vessel was sealed and heated in a pre-defined sequence in the microwave: I’ll be really very grateful. This landfill, which activities started inwas inadequately operated from the beginning untilwhen a reclamation plan was implemented to turn it into a sanitary lanfill.
Dumpsites can be scientifically investigated to obtain contamination profiles due to leachate seepage geotecina therefore assess soil properties relative to pollute transport and retention with a view at improving the design of new MSW landfills Ferrari et al.
Soil sampling was performed with a regular auger. During these operations it was observed that soil voids were filled with sludge down to the depth of 0. This paper presents an investigation of subsoil contamination underneath an unlined leachate pond in a year old dumpsite in the state of Sao Paulo, Brazil, which currently is going through boscoc process of reclamation to turn it into a sanitary landfill with adequate protection to the environment and human health.

All laboratory apparatuses e. Figure 3 presents a schematic diagram of the pond profile.
Skip to main content. For each round of microwave heating one vessel containing only 10 mL of nitric acid was used as a blank geoyecnia. Figure 5 — Soil sampling. Exhumation of an unlined leachate lagoon — a case study. Arsenic and cadmium were not detected in the chemical analysis, i.
Leachate pond Untilthe leachate generated in Botucatu Municipal Landfill was mainly stored in amiental unlined pond Figure 2without compacted clay liner and geomembrane. X-ray diffraction detected the presence of quartz, kaolinite, gibbsite, hematite and anatase.
Thank you very much. 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.

Serra Geral Formation comprises a set of basaltic rocks originated from volcanic flows which are intercalated with eolian fine-grained sandstone deposits. 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, Figure 2 View of the unlined leachate pond.
The samples were cubic with side length of 0. Sampling operations had to be changed Figure 5 the profiles had to be relocated. The final location can be viewed as green points in Figure 4. Fri Sep 25, 8: Log In Sign Up. As observed by Ferrari et al. The Political Genius of Abraham Lincoln. Results showed that the tropical sandy soil that composed the landfill foundation retained the investigated metals, so that their concentrations boscv not exceed limit acceptable values of soil contamination from the state of Sao Paulo.
For each field sample, triplicates were used to improve the accuracy of the results. In Brazil, inadequate disposal sites must be eradicated until in accordance with a federal law BRASIL, ; considering the estimated daily MSW generation ofton inonly Soil samples were collected in three profiles located inside the area of bboscov leachate pond at 6 depths ranging from the subsoil surface until 4- m depth.

The unlined leachate pond was deactivated and emptied after a new lined pond was built. In order to prevent subsoil contamination, bottom drainage and liner systems must be included in the design of sanitary landfills, i. This paper presents the exhumation of 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.
Since the end of last century, waste disposal in dumps – sites which receive wastes without any environmental protection – became inadmissible in several countries. Click here to sign up. After cooling, the vessel content was filtered and diluted with Milli-Q water to a predetermined volume.

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.
EPA, developed for partial extraction of metals. En este caso no se trata de un estudio de riesgo. Foram realizadas sondagens a trado manual com coleta de amostras para a The liquid sample was then submitted to chemical analysis. MSW disposal sites with elements and operational procedures that guarantee protection to the environment and human health.
Arsenic, cadmium, lead, copper and chromium were determined in the natural uncontaminated soil, in the leachate sludge deposited in the bottom of the pond and in the contaminated soil samples.
Who is online Users browsing this forum: The elements arsenic, cadmium, chromium, copper and lead were determined with about 5-mL liquid sample of the each solution. No registered users and 9 guests. How To Win Friends and A soil sample of 0. Background concentrations in the local soil were determined by sampling uncontaminated local soil outside the range of the landfill influence, i. Tata McGraw Hill Education, p. Datos del sector y tipo de proyecto 4. Figure 1 — Location of Botucatu Municipal Landfill regional and local views.
