“…Immobilization, or stabilization, techniques can be used to reduce excessive exposure of humans and terrestrial organisms to inorganic contaminants (Bolan et al, 2014). These techniques are mostly used at moderately contaminated sites, either singly or in combination with other remediation methods, for example as part of Gentle soil Remediation Options, (GRO) (Cundy et al, 2013). Immobilizing agents are generally mixed into the soil and the contaminants are bound through adsorption or precipitation.…”

Immobilization of trace elements in contaminated soils by zero-valent iron (ZVI) is a promising remediation method, but questions about its long-term performance remain unanswered. To quantify immobilization and predict possible contaminant remobilization on long timescales detailed knowledge about immobilization mechanisms is needed. This study aimed at assessing the long-term effect of ZVI amendments on dissolved copper and arsenic in contaminated soils, at exploring the immobilization mechanism(s), and at setting up a geochemical model able to estimate dissolved copper and arsenic under different scenarios.Samples from untreated and ZVI-treated plots in two field experiments where ZVI had been added 6 and 15 years ago were investigated by a combination of batch experiments, geochemical modeling and extended X-ray absorption fine structure (EXAFS) spectroscopy.Dissolved copper and arsenic concentrations were described by a multisurface geochemical model with surface complexation reactions, verified by EXAFS. The ZVI remained "reactive" after 6-15 years, i.e. the dissolved concentrations of copper and arsenic were lower in the ZVI-treated than in the untreated soils. There was a shift in copper speciation from organic matter complexes in the untreated soil to surface complexes with iron (hydr)oxides in the ZVI-treated soil. The pH value was important for copper immobilization and ZVI did not have a stabilizing effect if pH was lower than about 6. Immobilization of arsenic was slightly pH-dependent and sensitive to the competition with phosphate. If phosphate was ignored in the modeling, the dissolution of arsenate was greatly underestimated.

“…Soft re-uses are mostly mediated by plants, whether as part of the landscape of an open space, or for providing benefits of an urban 'green lung' or for a productive purpose such as growing biomass (Adelaja et al 2010;Haase, 2008;Mathey et al 2015;Sinett et al 2015). The growth of plants and hence the viability of soft re-uses is dependent on a suitable level of soil functionality (Cundy et al 2013). An ecologically informed approach can produce significant cost-benefits by building on the natural restoration often found on derelict sites (Handley 1996).…”

“…Inevitably, trade-offs must occur when designing a method for sustainability assessment (Bartke and Schwarze 2015). Stakeholder involvement is an important part of sustainability assessment for restoration and remediation projects to provide more robust and acceptable assessments (Cundy et al 2013, Pediaditi et al 2005, in accordance with the Bellagio principles (Hardi and Zdan 1997).…”

Optimising value from the soft re-use of brownfield sites

Soft re-use of brownfields describes intended temporary or final re-uses of brownfield sites which are not based on built constructions or infrastructure (‘hard' re-use). Examples of soft re-uses include the creation of public green space. These are essentially uses where the soil is not sealed. Often the case for soft re-use of brownfields has not been easy to demonstrate in strictly financial terms. The purpose of this paper is to describe a value based approach to identify and optimise services provided by the restoration of brownfields to soft re-uses, on a permanent or interim basis. A ‘Brownfield Opportunity Matrix' is suggested as means of identifying and discussing soft restoration opportunities. The use of ‘sustainability linkages' is suggested as a means of understanding the sustainability of the services under consideration and providing a structure for the overall valuation of restoration work, for example as part of design or option appraisal processes, or to support the solicitation of interest in a project
