“…The data presented above clearly illustrate the ineffectiveness of using sieving as a treatment option for soils similar to SCC soils. A similar conclusion was drawn by Yarlagadda et al 15 using some Resource Conservation and Recovery Act-designated soils. In addition, this is an important conclusion if one wished to model the resuspended soil emissions for air quality, since the source term can be easily identified by measuring the general concentration of metals in the soils without size-segregating to determine the concentration of the potential airborne fraction.…”

The city of East St. Louis, IL, has a history of abundant industrial activities including smelters of ferrous and nonferrous metals, a coal-fired power plant, companies that produce organic and inorganic chemicals, and petroleum refineries. A protocol for soil analysis was developed to produce sufficient information on the extent of heavy metal contamination in East St. Louis soils. Soil cores representing every borough of East St. Louis were analyzed for heavy metals-As, Cd, Cu, Cr, Hg, Ni, Pb, Sb, Sn, and Zn.

“…Solid waste disposals (open dumps, landfills, sanitary landfills or incinerators) represent a significant source of metals released into the environment (Yarlagadda et al 1995;Waheed et al 2010;Iwegbue et al 2010;Bretzel and Calderisi 2011;Rizo et al 2012). Leachate is produced primarily in association with precipitation that infiltrates through the refuse and normally results in the migration of leachate into the groundwater zone and pollutes it (Samuding 2009).…”

Assessment of heavy metal contamination in soil due to leachate migration from an open dumping site

The concentration of heavy metals was studied in the soil samples collected around the municipal solid waste (MSW) open dumpsite, Ariyamangalam, Tiruchirappalli, Tamilnadu to understand the heavy metal contamination due to leachate migration from an open dumping site. The dump site receives approximately 400-470 tonnes of municipal solid waste. Solid waste characterization was carried out for the fresh and old municipal solid waste to know the basic composition of solid waste which is dumped in the dumping site. The heavy metal concentration in the municipal solid waste fine fraction and soil samples were analyzed. The heavy metal concentration in the collected soil sample was found in the following order:The presence of heavy metals in soil sample indicates that there is appreciable contamination of the soil by leachate migration from an open dumping site. However, these pollutants species will continuously migrated and attenuated through the soil strata and after certain period of time they might contaminate the groundwater system if there is no action to be taken to prevent this phenomenon.

“…1,[7][8][9][10][11][12] One of the key issues addressed while developing the technology of decontamination of soils, sediments, and aquifer materials using a soil-washing reactor is related to the study of interactions of hydrophobic pollutants at the solid-water interface. 13,14 More likely than not, the physicochemical interactions, including sorption, desorption, and volatilization, are of utmost importance in deciding the ultimate fate process of the pollutant in an aquatic environment. Several investigators have worked to enhance the understanding of physicochemical interactions of hazardous pollutants at the aquatic interface of soil/ clay/sediment/aquifer, because it is long recognized that this understanding is focal to the success of soil-washing technology.…”

“…Several investigators have worked to enhance the understanding of physicochemical interactions of hazardous pollutants at the aquatic interface of soil/ clay/sediment/aquifer, because it is long recognized that this understanding is focal to the success of soil-washing technology. For example, specific studies have been carried out for washing soils/sediments contaminated with organics 2,4,15 and inorganics 1,8,9,13,16 and also modeling the sorption and desorption phenomenon. 17 Many isolated research efforts on development and application of quantitative structure activity relationships (QSARs) for predicting the sorption and desorption equilibrium at the activated carbon/water interface or activated carbon/air interface [18][19][20][21][22] have been reported in the literature.…”

This study addresses the issues related to decontamination of marine beach sand accidentally contaminated by petroleum products. Sorption and desorption of BTEX (i.e., benzene, toluene, ethylbenzene, and xylene) onto the sand from Uran Beach, located near the city of Mumbai, India, were studied, and isotherms were determined using the bottle point method to estimate sorption coefficients. Alternatively, QSARs (i.e., quantitative structure activity relationships) were developed and used to estimate the sorption coefficients. Experiments for kinetics of volatilization as well as for kinetics of sorption and desorption in the presence of volatilization were conducted in a fabricated laboratory batch reactor. A mathematical model describing the fate of volatile hydrophobic organic pollutants like BTEX (via sorption and desorption in presence of volatilization) in a batch sediment-washing reactor was proposed. The experimental kinetic data were compared with the values predicted using the proposed models for sorption and desorption, and the optimum values of overall mass transfer coefficients for sorption (K s a s ) and desorption (K d a d ) were estimated. This was achieved by minimization of errors while using the sorption coefficients (K p ) obtained from either laboratory isotherm studies or the QSARs developed in the present study. Independent experimental data were also collected and used for calibration of the model for volatilization, and the values of the overall mass transfer coefficient for volatilization (K g a g ) were estimated for BTEX. In these exercises of minimization of errors, comparable cumulative errors were obtained from the use of K p values derived from experimental isotherms and QSARs.
