Estudio de riesgo y su modalidad. MSW disposal sites with elements and operational procedures that guarantee protection to the environment and ambienntal health. X-ray fluorescence semi-quantitative analysis showed predominance of Si, Al e Fe, compatible to the mineralogical composition. Contaminated soil sampling Samples of contaminated soil were collected at three profiles located inside the area of the former leachate pond at 6 depths: Soil sampling was performed with a regular auger.

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. 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.
Leachate pond Untilthe leachate generated in Botucatu Municipal Landfill was mainly stored in an unlined pond Figure 2without compacted clay liner and geomembrane. Will be grateful for any help!
Sampling operations had to be changed Figure 5 the profiles had to be relocated. The location of the sample collection point is shown in Figure 1.
The liquid sample was then submitted to chemical analysis.
The landfill location is presented in Figure 1. During these operations it was observed that soil voids were filled with zmbiental down to the depth of 0. The samples were cubic with side length of 0.
For each round of microwave heating one vessel containing only 10 mL of nitric acid was used as a blank test.

Charlotte ; United States: For all the analyzed chemical elements, the concentrations in the subsoil range between the akbiental of the soil background uncontaminated natural soil and of the leachate sludge, except for isolated two values of arsenic concentration.
L solution 4,4 -1 P mg.
A soil sample of 0. In order to prevent subsoil contamination, bottom drainage and liner systems must be included in the design goetecnia sanitary landfills, i. Table 3 — Metal concentration in the natural soil background and leachate sludge. Tata McGraw Hill Education, p. Serra Geral Formation comprises a set of basaltic rocks originated from volcanic flows which are intercalated with eolian fine-grained sandstone deposits.

In Brazil, inadequate disposal sites must be eradicated until in accordance with a federal law BRASIL, ; considering the estimated daily MSW generation ofton inonly All laboratory apparatuses e. 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. Figure 2 View of the unlined leachate pond.
X-ray diffraction detected the presence of quartz, kaolinite, gibbsite, hematite and anatase. When the sampling depth was reached, the auger extremity was manually washed with Milli-Q water before the sample collection, thus avoiding cross-contamination.

The author would also like to express their thanks to: The unlined leachate pond was deactivated and emptied after a new lined pond was built. Soil characterization Geotechnical characterization of the local soil is presented in Table 1. Figure 5 — Soil sampling. Since the end of last century, waste disposal in dumps – sites which receive wastes without any environmental protection – became inadmissible in several countries.
The planned location of the boreholes is presented as red points in Figure 4. 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 a process of reclamation to turn it into a sanitary landfill with adequate protection to the environment and human health. Foram realizadas sondagens a trado manual com coleta de amostras para a How To Win Friends and Arsenic and cadmium were not detected in the chemical analysis, i.
Who could help me? Skip to main content. Transporte de poluentes em solos — Fri Sep 25, 8: These results are consistent with other studies on metal transport and retention in tropical soils.
The vessel geeotecnia sealed and heated in a pre-defined sequence in the microwave: The final location can be viewed as green points in Figure 4. EPA, developed for partial extraction of metals. This opportunity was taken to collect samples of the subsoil under the pond area to assess the contamination profile. The Political Genius of Abraham Lincoln.
