“…Conversely, high carbon isotope shifts of chlorinated benzenes in contaminated groundwater indicate that their biodegradation is controlled by anaerobic reductive dechlorination [61]. Research shows that dissolved organic carbon (DOC) degradation contributes to groundwater with low depleted values, which is the difference between dissolved organic carbon of carbon-13 (δ 13 C-DOC) and dissolved inorganic carbon of carbon-13 (δ 13 C-DIC).…”

The terrestrial components of the hydrological cycle include rainwater, surface water, and groundwater. Carbon (C) isotopes allow hydrologists to pinpoint the age of groundwater, track its flow rate, and identify the sources and processes. This research summarizes previous investigations conducted on the isotopes of groundwater and precipitation. The Scopus database contains works from authors from fifty nations, who have conducted research integrating C isotopes in groundwater and precipitation. The review shows that there have been few C isotope investigations on carbon storage and sequestration, as well as on δ13C of precipitation in arid regions. An integrated e-DNA investigation on the process of C isotope fractionation in diverse environments, as well as research on 13C of precipitation in arid regions before and after dust storms, is required to elucidate the relative contributions of biogenic, geogenic, and anthropogenic sources. However, carbon isotope fingerprints that are unique to individual compounds, such as those of fugitive gases, need sophisticated analytical equipment in order to be investigated, limiting this type of study to nations with robust scientific infrastructures and well-trained manpower. The International Atomic Energy Agency (IAEA) has been instrumental in this effort by providing collaborative research and analytical support, resulting in the development of a network for isotope data generation.

“…While compounds with a lower degree of chlorination are more susceptible to oxidative transformation, the biodegradation potential via anaerobic processes increases with the number of chlorine substituents in the molecule. In anoxic groundwaters and sediments, PeCB can undergo anaerobic reductive dechlorination to trichloro‐ and dichlorobenzenes (Trueba‐Santiso et al, 2022). Investigating the mechanism of pollutant transport in the presence of such microorganisms in order to better understand the risks of contamination of ground‐ and drinking water sources is therefore of utmost importance.…”
