“…Drawing on decades of remediation experience at the state, tribal, and federal level, brownfield cleanup takes a risk-based approach-meaning that the cleanup goals are based on anticipated exposure risks to human health and the environment-informed by the plan for subsequent reuse [34][35][36][37][38][39]. As with other developments, successful reuse has been associated with brownfield site size and location, incentives for developers, community support and integration of reuse with neighborhood plans, whereas conflicting land uses and unimproved infrastructure impede redevelopment efforts [31,35,39].…”

Limited research has examined brownfields clean-up, reuse choice and associations with flood risk or resilience. This cross-sectional analysis examines counties with U.S. Environmental Protection Agency (EPA) funded brownfield cleanups initiated from 2005 through 2009 and assesses the county-level relationship of green reuse with flood risk while accounting for county factors of resources, environmental stressors, race and ethnicity, location, and structural characteristics, as modified from the Gee and Payne-Sturges conceptual model of community environmental health. Flood plain designation predicted a three-fold odds of green reuse alone (OR = 2.96 [95% CI, 1.31-6.66]) and green with other reuses (OR = 2.88 [95% CI, 1.07-7.75]). Green reuse alone was influenced negatively when a county had an eastern or western US location or a larger proportion of population aged 5-24 and positively when population education levels were higher. Among counties with green and other reuse, low education was predictive. Conceptually, decisions for green reuse alone were driven by resources and location while decisions for green and other reuse were driven by resources, location and environmental stressors.

“…Nevertheless, flushing technology is based on the continuous flow of the flushing solution through the contaminated porous material layer. Hence, hydraulic permeability of the polluted matrix is an important limiting factor governing the applicability of the flushing technology (Khan et al 2004). We conducted a series of laboratory tests to account for the variability due to time of conditioning between the solution and the contaminated soil.…”

Soil flushing technology is an 'in situ' remediation technique involving the injection of a liquid solution. Applications of the soil flushing technique depend on the leachability of the pollutants and the environmental compatibility and total volumes of the solutions used. Therefore, experiments should consider these aspects by simulating the real phenomenon and using the most suitable reagents for the leachability of the different mineralogical forms present. Thirtyone laboratory tests were carried out (in batch and becker) to the complete exhaustion of the leaching capacity according to pH measurements. The reaction kinetics were studied by producing more than 300 solution samples during which the principal heavy metal concentrations, pH and Eh were measured. Leaching solutions containing various concentrations of hydrochloric, sulphuric, nitric and acetic acids were used. Mercury was leached using potassium iodide and acetic acid (pH 2). Analytes such as arsenic, cadmium, mercury, lead, selenium and zinc proved to be leachable in the investigated soil layer. However, high removal efficiencies could be obtained using different typological solutions, concentrations and volumes. The paper discusses the applicability of the soil flushing technique for different heavy metal contents and pH conditions of the flushing solution.

“…These anthropologic forces pose a threat to the health of flora, fauna and humans through the disposal of waste waters, soil contaminants, and release of toxic gasses into the atmosphere (Checa-Vizcaino et al, 2016). At present, special efforts are being made to develop new methods and technologies that can be applied to contaminated soil, water and air in order to reduce negative ecological and environmental effects resulting from human activities (Khan et al, 2004;Onwubuya et al, 2009;Desai et al, 2010;Gill et al, 2014).…”

Degradation of Food Manufacturing Wastes by a Fungal Isolate

Food manufacturing wastes, such as olive mill solid waste, tomato pomace and grape pomace are three wastes produced by food industries in the Region of Maule. One of the simplest strategies for the proper disposal of these residues is to directly eliminate them by cultivation with degrading mesophilic microorganisms, which use these wastes as their sole carbon source. A fungal strain was isolated from tomato peel and used to degrade food manufacturing wastes. This strain was effective in degrading olive mill solid waste, but partially degraded both grape and tomato pomace. Based on mycelium morphology, sequence of part of the ribosomal and internal transcribed spacer (ITS) DNA, the strain most probably belongs to Botrytis genera. This is the first report that uses a strain similar to Botrytis in degrading food manufacturing wastes from the Region of Maule.
