“…Control and remediation technologies are mainly divided into three stages: source control of pollution, diffusion of air pollution control, and contaminated site restoration. Barrier technology is a remediation method that isolates polluted soil from the surrounding environment by using impermeable barriers, lining technology, grouting wall, sheet-pile, geomembrane, and mud wall are main divisions [9,10].…”

Mishraq field hits soil and groundwater, eventually reaching the Tigris River. The process of hot water injection for sulfur extraction led to a change in the hydrological conditions of the area. The spread process of this water through the soil carries liquid dissolved sulfur towards the river that causes pollution of soil and river. The extent and concentration of dissolved sulfur were studied before and after proposed treatments. Also, the efficiency of these treatments would be estimated considering transport and diffusion theory in saturated/unsaturated states using the GEO-SLOPE software evaluating the extent of dissolved sulfur transfer through site soils in two cases. The first case represents the soil region without proposed treatments, and the second case represents the soil region with proposed treatments. The results show that a length of vertical barriers ranging between 180-200 m was efficient to prevent pollutants from moving. Also, the concentration and extent of contaminant spread in soil depended on the distance between vertical barriers and contamination source. Also, it found that at distances less than 300 m concentration of contaminant was high with a small range of soil, while at distances more than 300 m concentration of the contaminant was lower with a wider spread of soil.

“…The municipal sewage and industrial wastewater were discharged into the Xiang River, resulting in serious pollution, especially soil heavy metals pollution (Li et al, 2018). In the last ten years, soil pollution has been treated with varying ways in Zhuzhou (Wei et al, 2018). However, the problem is still serious because heavy metals are easy to transfer and diffuse in soil, water, and air (Nagajyoti et al, 2010).…”

The heavy metals contamination in soil has attracted increasing attention. In this study, the main objective was to determine three heavy metals (Cd, Pb, and Cr) of soils contaminated by smelting waste, and to evaluate pollution risk. The Pb (15.48 mg/kg) and Cd (311.39 mg/kg) mean concentrations exceeded the national standard, while Cr (48.60 mg/kg) concentration did not exceed. The Heavy metal fractions analysis showed that three heavy metals were dominated by FeMn oxides fraction (Fe-Mn). The correlation and cluster analysis indicated that there was significant correlation between Cd and Pb (0.55< r < 0.96), while Cr was not correlation to Cd and Pb. The environmental pollution of heavy metals was assessed by the ratio of secondary phase and primary phase (RSP). The result showed that RSP values of Cd, Pb, and Cr range from 13.05–54.28, 16.11–4.97 and 1.61–52.33, which indicated soil was serious contaminated by them. These results showed that smelting waste discharge led to this smelter soil being seriously contaminated by multiple heavy metals which have a tendency to transport and accumulate into deep soil due to their high fractional transformation.
