“…Electrical resistivity tomography, often used with other geophysical methods, has been used to identify the contaminated zone around waste landfills (e.g., in Portugal, Nigeria, Brazil, Vietnam, Indonesia, Singapore, Malaysia, Saudi Arabia, and Poland) [23,[29][30][31][32][33][34][35][36][37][38][39][40][41].…”

Reclaimed landfill areas are excluded from various development options including construction, while contaminated zones around such places have no such restrictions. The successful reclamation of landfills means that the old landfill visually fits in well with its surroundings, but soil and water contamination problems remain valid. Former landfills were built without properly preparing the land, which resulted in the migration of contaminants in groundwater for a long period after these landfills were closed, further resulting in the limited use of such areas, at least for some purposes. Due to the development of cities, landfills formerly located in suburbs are becoming a part of these cities. In order to optimally and safely use these spaces, knowledge regarding the quality of the soil and water environment is necessary. This article presents methodological considerations regarding the use of carbon and sulfur isotope methods to assess groundwater contamination around former municipal waste landfills, especially reclaimed municipal landfills. It has been shown that natural groundwater is characterized by low values of both δ13CDIC and δ34S (δ13CDIC from −20 to −10‰ and δ34S at approximately −5‰), whereas leachate-contaminated groundwater is characterized by high values of both parameters (δ13CDIC from −10 to + 5‰ and δ34S from +5 to +20‰). The aim of this article is to demonstrate that carbon and sulfur isotope methods extended via SWOT analysis are universal and reliable methods for assessing the migration of pollutants, thus facilitating decisions regarding management.

“…Some of the waste is recycled, some is subject to thermal transformation and composting, but nearly 40% of waste is still stored in a traditional way. This method poses the greatest threat to the natural environment and humans [3].…”

Leachates from landfills constitute a very complex environmental matrix with potentially toxic properties for both the environment and humans. Due to this fact, toxicological tests were carried out on landfill leachate (LL) obtained from the local landfill in Hryniewicze (Poland). The analyses included physicochemical studies of leachates and their impact on soil and plants, and studies conducted in bacterial models and human cell models. The results obtained indicate high contents of metals and organic matter, especially dangerous PAHs, in the tested leachate. This results in the influence of LL on changes in the content of assimilation pigments and oxidative stress observed in plants grown in soil fed with leachates. The effect of leachate on the growth of Sporosarcina pasteurii, Staphylococcus aureus, Lactobacillus rhamnosus, Saccharomyces boulardii and Candida albicans varied depending on the strain and LL dose. A particularly significant increase in proliferation after exposure to LL was noted for S. aureus. In studies conducted on human cancer cell lines representing three types of glioblastomas and one type of colorectal adenocarcinoma, a particularly significant increase in the viability of cells treated with LL was noted for the DLD-1 cell line. The results obtained, especially the stimulation of the growth of cancer cells and an increase in the number of pathogenic bacteria, indicate the potential toxic properties of the tested leachates. This is confirmed by the high level of oxidative stress in plants. The results indicate the need for continuous monitoring of waste landfills and leachates generated there.
