“…Four factors were extracted to represent the main factors for groundwater quality, and to identify the different pollution sources. The first factor, with the principal components of total hardness, Cl − and TDS (greater than 0.900) and the secondary components of SO 4 2− , Pb and Mn (ranging from 0.500 to 0.900), contributed approximately 49.181% to the groundwater quality, indicating that most of the groundwater pollution in this study area resulted from the leachate leakage of the MSW landfill, similar to the substantial studies that demonstrated that the main influential groundwater pollutants from landfills included Cl − , SO 4 2− , total hardness, TDS and trace metals [34][35][36][37][38]. The TDS of this landfill was mainly determined by Cl − and SO 4 2− ; therefore, Cl − was very mobile and generally constituted nonreactive tracers, as seen in Figure 6e [18], and SO 4 2− underwent far-reaching biochemical transformations [19].…”

Groundwater contaminations based on the release and transportation of leachate from municipal solid waste (MSW) landfills are a potential hazard to the ecosystem and its inhabitants. In this study, nine chemical compositions of groundwater quality were collected and analysed from 16 monitoring wells and two ponds around the Diaoyushan MSW landfill in the north of Jiangsu Province, China. Multiple analyses were performed to assess the redox conditions and the groundwater environment. It was indicated that the landfill was in a low and stable biodegradability phase, and the most influential phase was the initial stage of the landfill site; the leachate leakage was the principal pollution source (49.18%) for the local groundwater environment. Artificial drainage of Dongdasha village expanded the contaminant plume scopes and deteriorated water quality further. The polluted groundwater area was provided with high concentrations of total hardness, Cl−, SO42−, total dissolved solids (TDS) and Pb.

“…From the above particle size distribution curves for 5 sands, it reaches 90% of cumulative undersize passing through mesh screen between 400 and 500 microns. The authors can conclude that the predominant size of the studied sands is between 400 microns and 500 microns, which attributed it to the class of fine sand [14]. The small particle size of the latter facilitates the fixation of the organic material to the surface of adsorbent material which is generally more important when the particle size of the material is low.…”

Different coastal sands of the city of El Jadida are used to filter wastewater from a cardboard manufacturing plant combined with fly ash and bottom ash (by-products of a local power plant). The performances of five matrices of these elements are compared in infiltration-percolation in vertical columns. The study of particle size sand is performed beforehand. The chemical and mineralogical composition of fly ash and bottom ash are produced by X-ray fluorescence and X-ray diffraction respectively. The wastewater samples were collected during a complete cycle of production of the cardboard. The heavy metals content before and after filtration was obtained by atomic emission spectrometry with inductively coupled plasma (ICP-AES). The parameters analyzed were: total suspended solids (TSS), organic matter COD, BOD 5 , the potential hydrogen pH and heavy metals (iron, zinc and arsenic). The results are very conclusive and respect the essence of control required by Moroccan regulations (law 1606-06) related to discharges from the papermaking and cardboard industry.

“…The landfills are identified as important source of groundwater contamination with organic and nonorganic pollutants (Fatta et al, 2002;Li et al, 2008;Alslaibi et al, 2011;Regadío et al, 2012;Li et al, 2014). The aquafer contamination with leachate is serious environmental issue not only in developing countries, for example Morocco (Smahi et al, 2013), Malaysia (Zawawia et al, 2012), India (Gunjan et al, 2012), but also in the USA where approximately 75% of the landfills have negative impact on groundwater quality (Jones-Lee & Lee, 1993). Similar results are found in Denmark and other countries.…”

The urbanization and increasing growth of planet's population accumulates significant volume of disposed waste as well as increases risks on human health and environmental safety. Landfill systems are the dynamic, living in space and time, potentially harmful entities that must be managed in as careful and smart way as possible. There are many studies related to landfill emissions such as leachates and methane. However, there is a need for advanced understanding of landfill hydrological regime and risks related to climate change and associated changes of hydrological cycle. The comprehensive studies about the urban hydrology are available; however, application to landfill management is fragmentary and inconsistent in several aspects. Landfill in long term has an impact on hydrological cycle. The heterogeneous land surface is one of aspects; however, there are still unanswered questions about the urban environment impact on water balance components. The aim of this study is to describe fundamentals of landfill hydrology in urban hydrological response unit context as well as evaluate the potential risks to environment and human health related to landfill geomorphology and hydrological balance in temporal climate conditions. The landfill hydrological cycle has similarities with urban hydrological cycle; however, there are additional components related to landfill specification, e.g., irrigation or leachate recirculation as well as total produced leachate.
