“…This article presents a comparative analysis of groundwater quality at selected landfills in two EU countries: Poland and the Czech Republic, which use different technical securing systems [20,21]. The difference in applied securing systems is related to the technical solutions used in the base and cover systems.…”

In order to protect the components of natural environment, each landfill must be properly secured and the monitoring program should be adopted. This study aims to present a comparative analysis of groundwater quality at selected landfill sites in Poland and the Czech Republic, with a special attention given to the levels and temporal changes of heavy metals (HMs) concentrations measured in collected groundwater samples. A secondary objective was to detect possible leakages of pollutants from the landfill body, into the groundwater, and further into the environment. The assessment of groundwater quality was based on a comparison of HMs concentrations with standards provided by the European environmental laws. On the basis of the long-term monitoring period, it was revealed, for the Polish landfill site, that the groundwater quality is improving over time, especially due to remedial works applied. For the Czech landfill, it was observed that the quality of groundwater is not negatively affected by the operation of the landfill, but in the immediate vicinity of the landfill, the groundwater quality is significantly affected by the agricultural use of neighbouring lands, as well as by the storage of construction and demolition wastes. The results showed that the leachate did not leak outside the landfills, especially due to minimal concentrations of HMs, measured in groundwater samples, taken from the piezometers located in the outflow direction from the landfills.

“…z(x, y) = e −P8(x,y) + C 0 (16) where P8(x,y) is a general polynomial of the eights degree in x,y variables shaped as in Equation ( 17). (17) This equation approximates the height of landfill body surface with a high accuracy. C 0 -C 45 coefficients were calculated by using the Gauss-Newton iteration method [49,50].…”

“…In MSW landfills, there are also other influences that have to be taken into account and utilized for the future development of landfill body behaviour such as leachate production or development of landfill gas [ 16 , 17 ]. Landfill body settlement is a physical phenomenon caused by the existence of hollow spaces (voids) in the deposited waste.…”

Displacements of landfills play an important role in the reclamation process and geotechnical safety improvement of such sites. Landfill settlements are defined as a vertical displacement of waste body due to compression, degradable nature of the waste, and creep phenomenon of the waste particles. Waste composition is more diverse than natural soil. Thus, it has to be properly placed and compacted since the landfill body will continuously settle down. Several models of the landfill displacement estimation have already been developed. The aim of the present study was: (i) to review the methods of landfill settlements computation and (ii) to propose the model allowing landfill body displacements simulation based on monitoring datasets applying a Global Navigation Satellite Systems (GNSS) measurement. The new model employs Gauss-Newton iteration and Runge-Kutta methods to estimate landfill surface displacements. The objectives were to analyse and mathematically describe the landfill body displacements. The GNSS geodetic survey and computations allowed concluding that the landfill body has been transformed over the years. The results revealed that the curves of waste displacement are in agreement with the measured total displacement of the landfill, and all curves corresponding to waste displacement are perpendicular to the active edge of the landfill. In the period of a maximum of 4.5 years after the waste deposition with a layer of up to 16.2 m thickness, the phenomenon of expansion was observed, which then disappears, and more settlement occurs due to the gravity of upper layers. The analysed landfill as a whole does not experience significant displacements. Neither of the slope failures are observed, even for large inclination.

“…It may even be prudent to disinfect leachate from such landfills by employing one of the standard methods of conventional disinfection (Wang et al, 2020) or other appropriate techniques, such as solar water disinfection and photocatalytic agents (zinc oxide (ZnO), zinc oxide(1−) (ZnO -), silver (Ag)-zinc oxide nanoparticles) (Danwittayakul et al, 2020), carefully chosen to avoid corrosion of leachate transmission lines. Cohesive soil liners or cut-off walls may be employed to protect the environment from hazardous substances emanating from landfills with leachate (Koda and Osinski, 2017;Vaverková, 2019;Vaverková and Adamcová, 2014). As an example, cut-off walls were implemented at an old embankmenttype landfill in Poland, which lacked contamination protective systems, resulting in improvements in groundwater quality (Koda et al, 2013(Koda et al, , 2016.…”

COVID-19 is proving to be an unprecedented disaster for human health, social contacts and the economy worldwide. It is evident that SARS-CoV-2 may spread through municipal solid waste (MSW), if collected, bagged, handled, transported or disposed of inappropriately. Under the stress placed by the current pandemic on the sanitary performance across all MSW management (MSWM) chains, this industry needs to re-examine its infrastructure resilience with respect to all processes, from waste identification, classification, collection, separation, storage, transportation, recycling, treatment and disposal. The current paper provides an overview of the severe challenges placed by COVID-19 onto MSW systems, highlighting the essential role of waste management in public health protection during the ongoing pandemic. It also discusses the measures issued by various international organisations and countries for the protection of MSWM employees (MSWEs), identifying gaps, especially for developing countries, where personal protection equipment and clear guidelines to MSWEs may not have been provided, and the general public may not be well informed. In countries with high recycling rates of MSW, the need to protect MSWEs' health has affected the supply stream of the recycling industry. The article concludes with recommendations for the MSW industry operating under public health crisis conditions.
