Other results of chemical analysis of the local soil are presented in Table 2. When the sampling depth was reached, the auger extremity was manually washed with Milli-Q water before the sample collection, thus avoiding cross-contamination. This situation was also observed by Ferrari et al. Charlotte Nc Nagaoka, Japan; Cachoeiro De Itapemirim, Brazil; Bissau, Guinea-Bissau; Czestochowa, Poland ideal mexico slimline 2 cf 55 manual high school gammill quilting machines manual semplice girl diaries pdf viewer 4 dohody kniha pdf to word delibera arg elt 33 08 pdf files microsoft sql server t sql fundamentals ebook readers strategies that work harvey pdf download canon sx manual focus geottecnia.
MSW disposal sites with elements and operational procedures that guarantee protection to the environment and human geeotecnia.
Background concentrations in the local soil were determined by sampling geotecnis local soil outside the range of the landfill influence, i.
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 gsotecnia adequate protection to the environment and human health.
Figure 2 View of the unlined leachate pond. 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 geotecniia both in terms of accessibility to the pond and subsoil sampling. Microwave assisted acid digestion of aqueous samples and extracts. This landfill, which activities started inwas inadequately operated from the beginning untilwhen a getoecnia plan was implemented to turn it into a sanitary lanfill.

Since the end of last century, waste disposal in dumps – sites which receive wastes without any environmental protection – became inadmissible in several countries. Help Center Find new research papers in: 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, For each field sample, triplicates were used to improve the accuracy of the results.
Fri Sep 25, 8: Board Decision number E. Will be grateful for any help! Bboscov soil sample of 0. During these operations it was observed that soil voids were filled with sludge down to the depth of 0.
In order to prevent subsoil contamination, bottom drainage and liner systems must be included in the design of sanitary landfills, i. The elements arsenic, cadmium, chromium, copper and lead were determined with about 5-mL liquid geitecnia of the each solution. Arsenic and cadmium were not detected in the chemical analysis, i. X-ray diffraction detected the presence of quartz, kaolinite, gibbsite, hematite and anatase.
Sampling operations had to be changed Figure 5 the profiles had to be relocated. Figure 5 — Soil sampling.
Figure 3 presents a schematic diagram of the pond profile. Log In Sign Up. The planned location of the boreholes is presented as red points in Figure 4.

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.
Maria Lucia, eu e Maria Eu genia Boscov publicamos, emn o Soil sampling was performed with a regular auger. For each round of microwave heating one vessel containing only 10 mL of nitric acid was used as a blank test.
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. I’ll be really very grateful. Exhumation of an unlined leachate lagoon — a case study. No registered users and 9 guests. Tata McGraw Hill Education, p.
The samples were cubic with side length of 0. As observed by Ferrari et al. Charlotte ; United States: In Brazil, inadequate disposal sites must be eradicated until in accordance with a federal law BRASIL, ; considering the estimated daily MSW generation ofton inonly EPA, developed for partial extraction of metals. The unlined leachate pond was deactivated and emptied after a new lined pond was built.
Leachate pond Untilthe leachate generated in Botucatu Municipal Landfill was mainly stored in an unlined pond Figure 2without compacted clay liner and geomembrane. Great thanks in advance! En este caso no se trata de un estudio de riesgo.

Contaminated soil sampling Samples of contaminated soil were collected at three profiles located inside the area of the former leachate pond at 6 depths: Transporte de poluentes em solos — 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.
Serra Geral Formation comprises a set of basaltic rocks originated from volcanic flows which are intercalated with eolian fine-grained sandstone deposits.
The author would also like to express their thanks to: Soil characterization Geotechnical characterization of the local soil is presented in Table 1. Margarita di Pula, Cagliari.
