“…The natural background value of δ 13 C DIC in uncontaminated groundwater most often ranges from −20 to −10‰, but extreme values range from −24.2‰ (in Germany) to −4.48‰ (in Australia) (Table 1, Figure 1). The isotopic composition of inorganic carbon in groundwater under natural conditions in various parts of the world ranges from −28 to −3‰ [109]. Leachates are enriched in heavy carbon isotopes, and δ 13 C DIC values range from −5.5‰ (in Germany) to +25.9‰ (in Germany), with the most common values ranging from 0 to +20‰.…”

“…Intermediate values (from −10 to +5‰) were achieved in water contaminated with leachates, which predisposes this method to the identification of contamination. [47,69,109,111,[113][114][115][116]120,122].…”

“…A simple method (based on a two-component mixing model) can be employed to estimate the proportion of carbon derived from different sources of the DIC pool [66,109]. By interpreting the results of the inorganic carbon isotope tests using the mixing model, it is possible to determine the share of carbon originating from the decomposition of organic pollutants in the landfill and other sources (the decomposition of organic substances of natural origin and the decomposition of rocks and carbonate minerals).…”

“…In strongly anaerobic environments where the organic substrate is more abundant than the available oxidants, decomposition via fermentation and methane production occurs. In a polluted environment such as a landfill, carbonates usually precipitate, which means that the two-component mixing model takes into account organic substances of natural (sedimentary organic matter) and anthropogenic origin (waste in the landfill) [66,109]. In more complex conditions, three-component (e.g., [127,128]) and even four-component mixing models can be used (e.g., [129]).…”

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.
