“…Weakly acidic environment (pH < 7.0) has a greater influence on TCE removal ( Zhang et al, 2015a ). Temperature also plays a vital role in affecting the bioavailability of hydrophobic contaminants and influencing bacterial capability of growth and metabolism and enzymatic activities ( Wang et al, 2022 ; Yamazaki et al, 2022 ). Temperature can influence the anaerobic degradation rate and products of TCE by a Dehalococcoides -containing consortium (UC-1), because it affects the acclimation period and leads to the selection of Dehalococcoides populations ( Hu et al, 2013 ).…”

“…According to the USEPA, bioremediation accounts for 24% of soil and groundwater remediation technologies ( Wang et al, 2022 ). Compared with energy-intensive physical and chemical treatment methods, in situ bioremediation is an efficient method for TCE removal with less environmental impact and lower energy consumption ( Rao et al, 2022 ; Rossi et al, 2022a ; Yamazaki et al, 2022 ).…”

“…Over the past 50 years, human efforts have been made to remediate TCE pollution ( Suttinun et al, 2013 ). Biodegradation of TCE has received extensive attention from researchers due to its cost-effectiveness, environmental friendliness, and sustainability ( Shukla et al, 2014 ; Wang et al, 2022 ). Biodegradation utilizes the catabolic capabilities of microorganisms with specific enzymatic activities to degrade TCE ( Shukla et al, 2014 ).…”

Trichloroethylene (TCE) is a ubiquitous chlorinated aliphatic hydrocarbon (CAH) in the environment, which is a Group 1 carcinogen with negative impacts on human health and ecosystems. Based on a series of recent advances, the environmental behavior and biodegradation process on TCE biodegradation need to be reviewed systematically. Four main biodegradation processes leading to TCE biodegradation by isolated bacteria and mixed cultures are anaerobic reductive dechlorination, anaerobic cometabolic reductive dichlorination, aerobic co-metabolism, and aerobic direct oxidation. More attention has been paid to the aerobic co-metabolism of TCE. Laboratory and field studies have demonstrated that bacterial isolates or mixed cultures containing Dehalococcoides or Dehalogenimonas can catalyze reductive dechlorination of TCE to ethene. The mechanisms, pathways, and enzymes of TCE biodegradation were reviewed, and the factors affecting the biodegradation process were discussed. Besides, the research progress on material-mediated enhanced biodegradation technologies of TCE through the combination of zero-valent iron (ZVI) or biochar with microorganisms was introduced. Furthermore, we reviewed the current research on TCE biodegradation in field applications, and finally provided the development prospects of TCE biodegradation based on the existing challenges. We hope that this review will provide guidance and specific recommendations for future studies on CAHs biodegradation in laboratory and field applications.

“…In situ thermal desorption (ISTD) technologies have been widely applied as an efficient approach for remediating NAPL-affected sites. , During ISTD operation, the polluted subsurface zone is heated and extracted to promote volatilization and capture of the NAPL . Although the ISTD technologies offer promising environmental benefits, it is noteworthy that they significantly consume energy and cause a substantial carbon footprint .…”

In situ thermal desorption (ISTD) provides an efficient solution to remediation of soil and groundwater contaminated with nonaqueous phase liquids (NAPLs). Establishing a relationship between the subsurface temperature rise and NAPL removal is significant to reduce energy consumption of ISTD. However, the co-boiling phenomenon between NAPL and water poses a great challenge in developing this relationship due to the nonequilibrium heat and mass transport effects. We performed a systematic experimental investigation into the local temperature rise patterns at different distances from a NAPL pool and under different degrees of superheat by selecting four representative NAPLs (i.e., trichloroethylene, tetrachlorethylene, n-hexane, and noctane) according to their density and boiling point relative to water. The patterns of temperature rise indicated that the underground temperature field can be divided into three zones: the zone of local thermal equilibrium, the nonequilibrium zone affected by co-boiling, and the zone unaffected by co-boiling. We developed a pattern-recognition-based approach, which considers the effects of local heat and mass transport to establish a qualitative correlation between the temperature rise and NAPL removal. Our results give deeper insights into the understanding of subsurface temperatures in ISTD practice, which can serve as the guideline for more accurate and sustainable remediation.

“…Groundwater quality is not adversely affected by ATES systems with small temperature differentials (Possemiers et al, 2014), which make up 99% of ATES systems worldwide (Fleuchaus et al, 2018). Furthermore, ATES systems may also be combined or integrated synergistically with aquifer in-situ bioremediation systems (Ni et al, 2020;Wang et al, 2022), as changes in groundwater temperature can be exploited to alter biogeochemical processes and hasten or stimulate in-situ bioremediation processes (Bin Hudari et al, 2022;Keller et al, 2021;Regenspurg et al, 2020). The presence of three distinct temperature zones (background, cold well, warm well) in aquifers with ATES systems, together with advection caused by injection and extraction of water, may stimulate convective processes that facilitate the mixing required for in-situ chemical or biological remediation, and that move contaminants to regions where they can more easily be subjected to pump and treat (Zheng et al, 2022).The performance of ATES systems under various hydrogeological properties and operating conditions remains an emerging subject of intensive research in the literature (Birdsell et al, 2021;Kranz & Frick, 2013;Liu et al, 2020;Vidal et al, 2022), and a more complete quantitative characterization of it constitutes a key step toward wider economic and scientific acceptance of this environmentally sustainable technology (Hoekstra et al, 2020).…”

Seasonal warm and cold water storage in groundwater aquifers is a cost‐effective renewable energy technology for indoor heating and cooling. Simple dimensionless analytical solutions for the thermal recovery efficiency of Aquifer Thermal Energy Storage (ATES) systems are derived, subject to heat losses caused by thermal diffusion and mechanical dispersion. The analytical solutions pertain to transient pumping rates and storage durations, and multiple cycles of operation, and are applicable to various well configurations and thermal plume geometries. Heat losses to confining layers, its implications for optimizing plume geometries and aspect ratios, and heat spreading due to free convection are also discussed. This provides a general tool for broad and rapid assessment of aquifers and ATES systems. We show that if heat exchange with the confining layers is negligible, the thermal recovery efficiency of thermal plumes with cylindrical geometry is independent of the aquifer porosity and heat capacity C0. Therefore, if mechanical dispersion is negligible as is often the case, the only aquifer property that affects the recovery efficiency is the aquifer thermal conductivity. The field‐scale aquifer thermal conductivity λ can therefore be inferred from the recovery efficiency of a push‐pull heat recovery test. Remarkably, an increase in C0 could either increase, decrease, or not affect the recovery efficiency, depending on the thermal plume geometry. Hence, the analytical solutions reveal that the recovery efficiency is affected by complex interactions between the thermal plume geometry and aquifer properties. Approximate analytical solutions for subsurface temperature profiles over an entire ATES cycle are also derived.
