“…This allows the project team to take immediate action, rectify the problems, and ensure that the construction quality is maintained at the highest level. Regular on-site inspections also provide an opportunity for the inspector to communicate with the construction team, address any concerns, and provide guidance if necessary [36][37][38][39].…”

“…Additionally, it can be employed in the context of solute transport inside construction projects. The advectiondispersion model is used to evaluate the sensitivity of the model parameters to identify the primary elements that influence the solute transport model inside the designated study area [7,8]. Researchers have conducted analytical simulations to investigate the pollution of aquifers resulting from the accumulation of solid waste [9,10].…”

The liquid that seeps into the earth from landfills and removes garbage is called landfill leachate. Pollutants like organic and inorganic chemicals, xenobiotic substances, etc. are found in landfill leachate which contaminates groundwater. To study the contamination and treatment of landfill leachate to groundwater, Datong landfill was selected as a target zone. Samples of monitoring wells in the landfill site, the eastern collapse pond, and wells in groundwater from the goaf were tested and analyzed for TDS, conductivity, and dissolved oxygen (DO). To simulate all processes, various modules were built under different conditions. It was found that the leachate not only had polluted surface water but also groundwater. The simulation results showed that the pollution plume expanded spatially and temporally, mainly flowing from west to east and spreading to the north-south direction and reverse flow direction due to the low water level between the east and west sides. Anti-seepage walls and pumping-injection methods were used to control the migration and diffusion of pollution from landfill leachate. The simulation results also showed that both methods were effective in reducing the concentration and range of pollution plumes which would provide a theoretical basis for the treatment of pollutants in the Datong landfill site.

The objective of this study was to investigate a petroleum-contaminated groundwater site in northeast China. We determined the physicochemical properties of groundwater that contained total petroleum hydrocarbons (TPH) with a view to developing a scientifically robust strategy for controlling and remediating pollution of groundwater already contaminated with petroleum. Samples were collected at regular intervals and were analyzed for dissolved oxygen (DO), iron (Fe), sulfate (SO), electrical conductivity (Eh), pH, hydrogen carbonate (HCO), and enzyme activities of catalase (CAT), peroxidase (HRP), catechol 1,2-dioxygenase (C12O), and catechol 2,3-dioxygenase (C23O). We used factor analysis in SPSS to determine the main environmental characteristics of the groundwater samples. The results confirmed that the study site was slightly contaminated and that TPH levels were decreasing slightly. Some of the physicochemical variables showed regular fluctuations; DO, Fe, and SO contents decreased gradually, while the concentrations of one of the microbial degradation products, HCO, increased. Microorganism enzyme activities decreased gradually. The microbiological community deteriorated noticeably during the natural attenuation process, so microbiological degradation of pollutants receded gradually. The HCO content increased and the pH and Eh decreased gradually. The groundwater environment tended to be reducing.
