“…Runoff and deposition are the two main pathways of HMs migration in soil and groundwater (Figure 1b) (Qiao et al, 2019). Some HMs enter the runoff through dissolution, while the other part is adsorbed on soil particles and then migrated through runoff (Qiao et al, 2023;Wei et al, 2024). There are many effects that can affect the migration of HMs in soil and groundwater, including the physical (particle size, water content, roughness) as well as chemical properties (pH, concentration) of the soil and groundwater (Ceballos et al, 2023;Feng et al, 2023;Qiao et al, 2023).…”

Ye et al found that agricultural soils are accompanied by more HMs migrating during natural rainfall compared to urban and industrial soil (Ye et al, 2022) of which, Cu and Cd were more easily released with increasing rainfall intensity.…”

Soil and groundwater contamination has always been a global concern. Contaminants are migrated and transformed in the soil and groundwater environments, which in turn pose potential environmental risks to humans. This paper describes four typical contaminants, including heavy metals, polycyclic aromatic hydrocarbons, microplastics, and perfluorinated and polyfluoroalkyl substances. Based on a systematic summary of the sources, hazards, and migration behaviors of these four contaminants, various existing remediation methods are analyzed, and the advantages and disadvantages of different methods are discussed. Finally, the future research prospects of soil and groundwater remediation are described, and the significance of the study of contaminant migration and remediation in the subsurface environment is emphasized. This research can help to provide theoretical and technical support for the study of contaminant migration and removal in soil and groundwater environments, and further improve the removal rate in actual contaminant sites.

“…Regional soil samples display a pH of 2.65-8.91, with an average of 5.87, which is weakly acidic. Human activities, particularly industrial processes (flotation processes), contribute to a reduction in soil pH [76,77], impacting the migration and enrichment of HM pollutants [78][79][80]. For example, soil acidification leads to a significant increase in the migration rates of Cd and Pb in areas with residual industrial facilities [81,82].…”

Understanding the contamination and sources of heavy metal(loid)s (HMs) at historical sites is vital for safeguarding human health and the ecological environment. This study focused on As, Hg, Cd, Cu, Pb, Ni, and Cr concentrations in the residual soil, groundwater, and surface water around a mineral processing plant. The sources of these elements and the human health risks posed by them were evaluated using various indexes. Soil HM concentrations exceeded background values for Yunnan Province, ranked as As > Pb > Cd > Cu > Hg > Ni. The river water met China's Class II waterbody standard; however, Cd, Cu, Pb, and pH exceeded the maximum permissible sewage discharge concentrations in the accumulated water. The groundwater showed severe HM pollution, meeting China's Class III water quality standard. The average value of the Nemerow pollution index was consistent with that of the single-factor pollution index in the following order: As > Pb > Cd > Ni > Cu > Hg. Children face heightened risk through the oral ingestion of As, Cd, and Pb, particularly in high-value sampling points in the residue deposit area. The main sources of these pollutants are anthropogenic activities and the soil formation matrix.

“…Their results showed that the basin experienced a significant increase in the stream and sediment runoff due to an increase in farmland and settlement areas. SWAT have been used for simulating stream flow [37], phosphorus export [38], pollutants [39,40], microorganisms [41], trends in frequencies of extreme precipitation and floods [42], greenhouse gas emissions [43][44][45], and water quality [32,46,47] in several catchments in Europe. Several studies showed that SWAT is not very sensible for land-use change, besides ET, simply because the corresponding change in soil parameters is not captured adequately [48][49][50].…”

Assessing Impacts of Land Use and Land Cover (LULC) Change on Stream Flow and Runoff in Rur Basin, Germany

Understanding the impact of land use/land cover (LULC) change on hydrology is the key to sustainable water resource management. In this study, we used the Soil and Water Assessment Tool (SWAT) to evaluate the impact of LULC change on the runoff in the Rur basin, Germany. The SWAT model was calibrated against the observed data of stream flow and runoff at three sites (Stah, Linnich, and Monschau) between 2000 and 2010 and validated between 2011 and 2015. The performance of the hydrological model was assessed by using statistical parameters such as the coefficient of determination (R2), p-value, r-value, and percentage bias (PBAIS). Our analysis reveals that the average R2 values for model calibration and validation were 0.68 and 0.67 (n = 3), respectively. The impacts of three change scenarios on stream runoff were assessed by replacing the partial forest with urban settlements, agricultural land, and grasslands compared to the 2006 LULC map. The SWAT model captured, overall, the spatio-temporal patterns and effects of LULC change on the stream runoffs despite the heterogeneous runoff responses related to the variable impacts of the different LULC. The results show that LULC change from deciduous forest to urban settlements, agricultural land, or grasslands increased the overall basin runoff by 43%, 14%, and 4%, respectively.
