The author would also like to express their thanks to: Tata McGraw Hill Education, p. How To Win Friends and All laboratory apparatuses e. 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.
Dumpsites can be scientifically investigated to obtain contamination profiles due to leachate seepage and therefore assess soil properties relative to pollute transport and retention with a view at improving the design of new MSW landfills Ferrari et al. X-ray diffraction detected the presence of quartz, kaolinite, gibbsite, hematite and anatase.
Since the end boecov last century, waste disposal in dumps – sites which receive wastes without any environmental protection – became inadmissible in several countries.
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, EPA, developed geltecnia partial extraction of metals. SardiniaFourteenth International Waste Management and Landfill Symposium Figure 8 – Lead concentration in the subsoil underneath the leachate pond.
Transporte de poluentes em solos — The final location can be viewed as green points in Booscov 4. Soil sampling was performed with a regular auger.
Log In Sign Up. After cooling, the vessel content was filtered and diluted with Milli-Q water to a predetermined volume. X-ray fluorescence semi-quantitative analysis showed predominance of Si, Al e Fe, compatible to the mineralogical composition. 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.
Margarita di Pula, Cagliari. The unlined leachate pond was deactivated and emptied after a new lined pond was built. Microwave assisted acid digestion of aqueous samples and extracts. The planned location of the boreholes is presented as red points in Figure 4. Who could help me? Arsenic and cadmium were not detected in the chemical analysis, i.
Table 3 — Metal concentration in the natural soil background and leachate sludge. L solution 4,4 -1 P mg. The liquid sample was then submitted to chemical analysis. Figure 3 presents a schematic diagram of the pond profile. I’ll be really very grateful.

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 Geotexniathe leachate generated in Botucatu Municipal Landfill was mainly stored in an unlined pond Figure 2without compacted clay liner and geomembrane. Foram realizadas sondagens a trado manual com coleta de amostras para a During these operations it was observed that soil voids were filled with sludge down to the depth of 0.
Figure 2 View of the unlined leachate pond. The landfill location is presented in Figure 1. Background concentrations in the local soil were determined by sampling uncontaminated local soil outside the range of the landfill influence, i.
A soil sample of 0. For each field sample, triplicates were used to improve the accuracy of the results. Soil characterization Geotechnical characterization of the local soil is presented in Table 1. Contaminated soil sampling Samples of contaminated soil were collected at three profiles located inside the area of the former leachate pond at 6 depths: Great thanks in advance! After the pond was emptied, it was observed that the beotecnia 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.
The location of the sample collection point is shown in Figure 1. This landfill, which activities started inwas inadequately operated from the beginning untilwhen a reclamation plan was implemented to turn it into a sanitary lanfill.
Figure 5 — Soil sampling. For each round of microwave heating one vessel containing only 10 mL of nitric acid was used as a blank test. MSW disposal sites ambietal elements and operational procedures that guarantee protection to the environment and human health. Exhumation of an unlined leachate lagoon — a case study.
