Shallow Part

It studied the geological properties and contamination characteristics of soil from contaminated sites of typical chromate plants in western plateau of China. The results indicated that in the shallow part of 0-4m, it was mainly loess-like soil and in the depth of 4-18m, it was mainly gravels and pebbles. The soil had better permeability and ex-situ washing treatment is recommended. The soil was severely contaminated and the concentration of chrome (Ⅵ) was as high as 16,000mg/kg. Based on the analysis, it developed a two-stage demonstration project of countercurrent ex-situ washing plus chemical stabilization with daily capacity of 20m3 soil and a demonstration project of chemical reduction and precipitation plus advanced treatment of filter bed with daily capacity of 200m3 wastewater. After treatment, the concentration of chrome (Ⅵ) in soil was less than 100mg/kg and that in water was reduced to below 0.05mg/L from 1,000mg/L, which can meet the requirements of third-grade groundwater quality standard.

With an urgent need for effective management of petroleum-contaminated sites, a GIS-aided simulation (GISSIM) system is presented in this study. The GISSIM contains two components: an advanced 3D numerical model and a geographical information system (GIS), which are integrated within a general framework. The modeling component undertakes simulation for the fate of contaminants in subsurface unsaturated and saturated zones. The GIS component is used in three areas throughout the system development and implementation process: (i) managing spatial and non-spatial databases; (ii) linking inputs, model, and outputs; and (iii) providing an interface between the GISSIM and its users. The developed system is applied to a North American case study. Concentrations of benzene, toluene, and xylenes in groundwater under a petroleum-contaminated site are dynamically simulated. Reasonable outputs have been obtained and presented graphically. They provide quantitative and scientific bases for further assessment of site-contamination impacts and risks, as well as decisions on practical remediation actions.

Decision Making Tool

The paper presents a methodology to assess the solutions for the management of contaminated sites. For defining these solutions there were developed two main activities. First one consists in a detailed site investigation to define its geological, hydrogeological characteristics and surely the contamination level. The second activity is dedicated to the assessment of risk generated by the soil, subsoil, air, and groundwater contamination, by using a professional software. The methodology was applied to a real case study. The results showed that for non-carcinogenic compounds the risk is above the thresholds establish by legislation. The conclusion is that measures to mitigate this risk must be taken, based on a feasibility study that will be realised in the next stage of the research.

Pb Pollution

Gobeil’s model is one of the most widely used models to identify lead (Pb) pollution sources in the environment. It is based on a set of equations involving Pb isotope fractions. Although a well-established numerical method, Gobeil’s model is often unable to provide an accurate estimation of each pollution sources’ contribution. This paper comprehensively examines the drawbacks of Gobeil’s model based on a numerical analysis and proposes a revised numerical method that provides a more accurate estimation of Pb pollution sources. Briefly, the mathematical inaccuracy of Gobeil’s model mainly lies in the misinterpretation of “lead fingerprint ratio balance.” To address this problem, the new analytic model relies on the mass balance of total lead in the contaminated sites, and uses a set of linear equations to obtain the contribution of each pollution source based on the lead fingerprint. A subsequent case study from an industrial park in Guanzhong area of Shaanxi Province in China shows that we can calculate the lead contribution rates accurately with the new model.
