    • ...subject of great attention in the latest decade, while much assessment and clean-up work were carried out (Gavrilescu 2005; Scholz and Schnabel 2006)...
    • ...For the treatment of contaminated ground, soil vapor extraction (SVE), solidification/stabilization, in situ soil flushing are most frequently used while for groundwater remediation air sparging (AS) is commonly used (Kim et al. 2002; Khan et al. 2004; Gavrilescu 2005, 2009)...
    • ...In the second half of the 20th century, increasing efforts were made toward containing and cleaning contaminated groundwater (Kovalock 2000; Harrison 2001; Gavrilescu 2005)...
    • ...The most important physical property of soil subsurface materials, relevant for the geochemical interactions are texture and surface area (NRC 1999; Gavrilescu 2005), while the most significant chemical property is mineralogy...
    • ...In addition, the relevant properties of contaminants for selection of the most appropriate clean-up technology should be defined in terms of (ITRC 2002; Gavrilescu 2005; Gavrilescu et al. 2009):...
    • ...Contaminant transport and transformations in soil and groundwater have been widely studied in relation with remediation strategies, since they are largely correlated with the physical and chemical properties of soil and groundwater (Boulding and Ginn 2004; Gavrilescu 2005; Pavel and Gavrilescu 2008; Gavrilescu et al. 2009)...
    • ...Research evidenced that transformation processes in soil and groundwater can lead to (Boulding and Ginn 2004; Khan et al. 2004; Gavrilescu 2005):...
    • ...Techniques for soil remediation can globally be applied in three ways (Dott et al. 1995; USEPA 2000; Mulligan et al. 2001; Gavrilescu 2004, 2005; Khan et al. 2004; Gavrilescu et al. 2009):...
    • ...In general, remediation technologies are classified into four categories based on the process acting on the contaminant (Kovalock 2000; USEPA 2000; Gavrilescu 2005, 2009, http://www.on.ec.gc.ca/pollution/ecnpd/tabs/tab22-e...
    • ...When a remediation option has to be applied, the following aspects should be accounted (Hyman and Dupont 2001; Gavrilescu 2005, 2008; Pavel and Gavrilescu 2008) (Table 1):...
    • ...POPs remediation technologies use physical, chemical, or biological processes that attempt to eliminate, reduce, isolate, or stabilize a contaminant or a group of contaminants (NRC 1997; Crawford et al. 2004; Gavrilescu 2005; Rubin and Burhan 2006)...
    • ...Chemical degradation or abiotic degradation occur by different reactions including hydrolysis, oxidation‐reduction, and ionization that usually happen through the presence of acidity or alkalinity, therefore, related to pH (Tarr 2003; Gavrilescu 2005)...
    • ...Table 4 Technologies for remediation of persistent organic pollutants groundwater and soil (Verstraete and Devliegher 1996; NRC 1999; Gavrilescu 2005)...
    • ... and sites polluted with POPs, but their selection to treat a specific compartment has to take into account three basic principles: the amenability of the pollutant to biological transformation to less toxic products (biochemistry), the accessibility of the contaminant to microorganisms (bioavailability) and the opportunity for optimization of biological activity (bioactivity) (Dua et al. 2002; Crawford et al. 2004; Ward and Singh 2004; ...
    • ...Bioaugmentation entails the addition of microorganisms indigenous or exogenous to the contaminated sites, but two factors has to be considered as limiting the use of supplementary microbial cultures, such as (El Fantroussi and Agathos 2005; Gavrilescu 2005 ;S emprini et al.2007): (1) non-indigenous cultures rarely compete well enough with an indigenous population to develop and sustain useful population levels and (2) most soils with ...
    • ...Biosparging requires injection of pressurized air under the water table to increase oxygen concentrations and enhance the rate of biological degradation of contaminants by naturally occurring bacteria (Gavrilescu 2005; Kao et al. 2008)...
    • ...Bioventing has emerged as one of the most cost effective in situ technologies available to address petroleum light-hydrocarbon spills, one of the most common sources of soil pollution (Gavrilescu 2005; Eyvazi and Zytner 2009; Magalha ˜esa et al. 2009)...

    • ...However, atrazine is degraded relatively slowly in the environment, with an average half-life ranging from 4 to 57 weeks (Anderson and Georgeson 1989; Erickson and Lee 1989), and has been detected in soil as well as in groundwater and surface water in several countries (Belluck et al. 1991; Gavrilescu 2005)...

    • ...Atrazine is also environmentally persistent: the half-life of atrazine in soil has been estimated at between 4 and 57 weeks (5), and atrazine has been detected in both surface and ground waters in several countries (15, 51, 53) at concentrations up to 4.6 M...
