Chemical pollution and toxicity of water samples from stream receiving leachate from controlled municipal solid waste (MSW) landfill

The analysis of technical measures allowing to control the municipal solid waste disposal (MSW) landfill with the purpose of emission reduction at different stages of the life cycle is presented. The review of the latest research in the field of implementation of technical measures at the operational and aftercare period is conducted: controlled water infiltration, collection of biogas, aeration of the landfill body, installation of methane oxidation cover systems. It is substantiated that the choice of a technical measure for management of the disposal for MSW landfill should be carried out taking into account the ultimate goal: reduction of biogas and leachate emissions, acceleration of waste decomposition processes, reduction of the impact of the landfill on environmental objects at the aftercare period. Criteria for choosing technical measures for reduction biogas and leachate emissions, boundary conditions and peculiarities of their implementation at different stages of the life cycle of the landfill have been established.

The Impact

Ground water samples in and around from the dumpsite located in Arumuganeri were studied to assess the impact of Municipal solid waste on the ground water resources. Ground water samples were collected from the 5 different bore-wells in and around the dumpsites.The collected water samples were analyzed for parameters of Total Dissolved Solids (TDS), Total Alkalinity (TA), Total hardness, chloride and dissolved oxygen. The results were observed in each sample , compared with standards WHO, ICMR, ISI and thus an attempt was made to ascertain whether the quality of ground water is fit or not for drinking and other purposes.

Landfill Sites

Abstract The rational and scientific selection of Municipal Solid Waste (MSW) landfill sites is becoming increasingly important, due to the continuous growth of MSW worldwide. Multi-source information is employed to ensure the accuracy of the evaluation criteria, including hydrogeological, morphological, environmental, climatic and socio-economic data. In the fuzzy logic environment, a Fuzzy Analytic Hierarchy Process (FAHP) and GIS spatial technique have been utilized to locate potential landfill sites. Landfill Site Selection Results (LSSR) were divided into three categories: suitable, less suitable, and unsuitable. Suitable areas were further divided into high, moderate, and low levels. We used the field investigations of 28 standardized landfill sites in the Hexi Corridor of China that comply with the China National Standard (CNS) to verify the LSSR. These sites are then ranked utilizing group fuzzy MULTIMOORA. These methods were more feasible and accurate in assessing the suitability of MSW landfills. The highlights of our methods were as follows: (1) The uncertainty of AHP expert scoring reduced by employing the fuzzy membership function, and the decision efficiency of spatial analysis improved as well. (2) Verification results showed that the main LSSR met the CNS perfectly and located suitable areas, with an accuracy of 93% (26 out of 28 sites). (3) In the highly suitable areas, 11 candidate areas were selected for the MSW landfill site construction in the Hexi Corridor. Furthermore, technical countermeasures for the standardized management of MSW landfills were proposed for the Hexi Corridor, which is critical for ecological/environmental protection.

The municipal solid waste (MSW) landfill in Vientiane, Laos, which receives > 300 tons of waste daily, of which approximately 50% is organic matter, has caused serious environmental problems. This study was conducted to investigate the accumulated levels of heavy metals (HMs) (cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn)) in water (surface and groundwater), soil, and plants between dry and wet seasons according to the standards of the Agreement on the National Environmental Standards of Laos (ANESs), Dutch Pollutant Standards (DPSs), and the World Health Organization (WHO), respectively. Although no impact of pollution on the surface water was observed, the levels of Cr and Pb in the groundwater significantly exceeded the basics of ANESs and WHO in both seasons. The pollution caused by Cd and Cu reached the eco-toxicological risk level in the landfill soils and its vicinity. The vegetable Ipomoea aquatica, which is consumed by the nearby villagers, was seriously contaminated by Cr, Pb, Cu, and Zn, as the accumulation of these toxic metals was elevated to much greater levels as compared to the WHO standards. For the grass Pennisetum purpureum (elephant grass), the quantities of HMs in all plant parts were extreme, perhaps due to the deeper growth of its rhizome than I. aquatica. This study is the first to warn of serious HM pollution occurring in the water, soil, and plants in the MSW landfill of Vientiane, Laos, which requires urgent phytoremediation. The indication of what sources from the MSW principally cause the pollution of HMs is needed to help reduce the toxicological risks on Lao residents and the environment in Vientiane as well.
