Reclamation of a Midwest brownfield site using agronomic and turf species

Johnson, Amanda M. 14 December 2013 (has links)
Plant species were assessed for recolonization of a brownfield in Muncie, IN. In a greenhouse study, soil was seeded to perennial ryegrass (Lolium perenne), red clover (Trifolium pratense) and sunflower (Helianthus annuus). Selected pots were amended with leaf compost and mycorrhizal fungi. Soil and plant tissue were analyzed after 30 and 90 days. Ryegrass and compost were studied at the brownfield site. In the greenhouse, red clover was capable of concentrating the greatest quantity of Cd, Cu, Cr, Ni, and Pb in above-ground biomass (all soil treatments combined). Compost + mycorrhizal fungi treatment resulted in highest Cd, Cu, and Zn plant concentrations (all plant treatments combined). Compost resulted in the highest tissue Cr and Ni concentrations. The reported study demonstrates that this brownfield is capable of being revegetated by turf and legume species. Each infertile and/or toxic site must be assessed for revegetation species on a case-by-case basis. / Department of Natural Resources and Environmental Management

A Least-Cost Strategy for Evaluating a Brownfields Redevelopment Project Subject to Indoor Air Exposure Regulations

Wang, Xiaomin 20 August 2012 (has links)
Over the course of the past several decades the benefits of redeveloping brownfields have been widely recognized. Actions have been taken to foster sustainable redevelopment of brownfields by government, policy makers and stakeholders across the world. However, redevelopments encounter great challenges and risks related to environmental and non-environmental issues. In this work, we intend to build a comprehensive and practical framework to evaluate the hydrogeological and financial risks involved during redevelopment and to ensure developers reserve sufficient capital to cover unexpected future costs within the guarantee period. Punitive damages, which contribute to these costs, are in this thesis solely associated with the cost of repossessing a house within a development should the indoor air concentration of TCE exceed the regulatory limit at a later time. The uncertainties associated with brownfield remediation have been among the barriers to brownfield redevelopment. This is mainly caused by the lack of knowledge about a site’s environmental condition. In order to alleviate uncertainties and to better understand the contaminant transport process in the subsurface, numerical simulations have been conducted to investigate the role of controlling parameters in determining the fate and transport of volatile organic compounds originating from a NAPL source zone located below the water table in the subsurface. In the first part of this thesis, the numerical model CompFlow Bio is used on a hypothesized three-dimensional problem geometry where multiple residential dwellings are built. The simulations indicate that uncertainty in the simulated indoor air concentration is sensitive to heterogeneity in the permeability structure of a stratigraphically continuous aquifer with uncertainty defined as the probability of exceeding a regulatory limit. Houses which are laterally offset from the groundwater plume are less affected by vapour intrusion due to limited transverse horizontal flux of TCE within the groundwater plume in agreement with the ASTM (2008) guidance. Within this uncertainty framework, we show that the Johnson and Ettinger (1991) model generates overly-conservative results and contributes to the exclusion zone being much further away from the groundwater plume relative to either CompFlow Bio or ASTM (2008). The probability of failure (or the probability of exceedence of the regulatory limit) is defined and calculated for further study. Due to uncertainties resulting from parameter estimation and model prediction, a methodology is introduced to incorporate field measurements into the initial estimates from the numerical model in order to improve prediction accuracy. The principle idea of this methodology is to combine the geostatistical tool kriging with the statistical data assimilation method Kalman filter to evaluate the worth and effectiveness of data in a quantitative way in order to select an optimal sampling scenario. This methodology is also used to infer whether one of the houses located adjacent to affected houses has indoor air problems based on the measurements subject to the observation that the affected house is monitored and has problems and developers have liability if a problem occurs. In this part of the study, different sampling scenarios are set up in terms of permeability (1 – 80 boreholes) and soil gas concentration (2, 4 and 7 samples) and three metrics are defined and computed as a criterion for comparison. Financing brownfield redevelopment is often viewed as a major barrier to the development process mainly due to risks and liabilities associated with brownfields. The common way of managing the risk is to transfer it to insurers by purchasing insurance coverage. This work provides two different strategies to price the risk, which is equivalent to an insurance premium. It is intended to give an instructive insight into project planning and feasibility studies during the decision-making process of a brownfield project. The two strategies of risk capital valuation are an actuarial premium calculation principle and a martingale premium calculation principle accounting for the hydrogeological and financial uncertainties faced in a project. The data used for valuation are the posterior estimates of data assimilation obtained from the results of different sampling scenarios. The cost-benefit-risk analysis is employed as a basis to construct the objective function in order to find the least cost among sampling scenarios for the project. As a result, it shows that drilling seven boreholes to extract permeability data and taking soil gas samplings in four locations or seven locations alternatively give the minimum total cost. Sensitivity analysis of some influential parameters (the safety loading factors and the possible methods to calculate the probability of failure) is performed to determine their roles of importance in the risk capital valuation. This framework can be applied to provide guidance for other risk-based environmental projects.

PŘIBYL, David January 2012 (has links)
The purpose of this thesis is to highlight the issue of brownfields. Green Meadow is still dominant because investors often care about making their edifice was built on the spot where now nothing happened, but on the other hand, brownfields have their advantages and disadvantages. The content of this paper is a general definition and the definition of terms as they are perceived by organizations that issue. The aim of this thesis is to evaluate the economic regeneration of brownfield sites in selected South Bohemian region consisting of the assessment of costs and benefits associated with brownfields. Brownfields selection was made based on the availability of information and the suitability of the sample for evaluation.

Brownfields - komparace venkovských oblastí regionů Děčínska a Ústí nad Labem / Brownfields - comparison of rural areas in the regions of Děčín and Ústí nad Labem

HASALOVÁ, Tereza January 2014 (has links)
Nowadays brownfields objects matter not only in major industrial cities, but also in small settlements and rural areas. Even there are abandonned and dilapidated agricultural areas, farms and other buildings as a result of declining employment rate in the primary sector, growing interest in the service sector or increasing import of agricultural production. Abandonned buildings induce a negative aesthetic appearance of the landscape and disrupt the quality of life of residents nearby.

Nas últimas décadas alguns países vêm implementando projetos de recuperação ambiental com a finalidade de reintegrá-los à dinâmica urbana com novas funções. Para o desenvolvimento do tema, neste trabalho foi escolhido o termo entrave espacial para ser utilizado com o mesmo significado de brownfield. Neste contexto, aterros de resíduos sólidos desativados são brownfields / entraves espaciais, porque provocam descontinuidades urbanas e dificultam o uso mais eficiente do espaço quando atingidos pelo crescimento urbano desordenado de um município, mas que podem ter seu reuso antecipado se procedimentos técnicos de controle e recuperação ambiental e algumas adequações forem efetivados visando antecipar apropriação dessas áreas para uso público. Essa pesquisa investiga as condições atuais dos brownfields / entraves espaciais, caracterizados por aterros desativados operados pela Prefeitura Municipal de São Paulo, a partir da década de 70, analisa as condicionantes de risco ambientais para a utilização pós-encerramento, os interesses do poder público e da população local na refuncionalização da área do Aterro Desativado de Vila Albertina, constatando que está previsto a recuperação ambiental e implantação de parques em áreas de aterros desativados nos próximos anos através da atuação conjunta de poder público e empreendedores privados. / Brownfields are abandoned or underused pieces of space, resulting from the shut down of damaged and/or contaminated enterprises. During the last decades, some countries have implemented projects concerning the environmental recovery, aiming to get their reintegration to the urban dynamics through new functions. For the development of the theme, in this issue, the term space impediment was chosen to be used with the same meaning as brownfield. So, in this context, urban solid residues landfills are meant brownfields / space impediment because they provoke urban discontinuity and make it difficult, the more effective pieces of land usage when they are reached by a disorganized municipal growth, although they may get their anticipate reutilization if, technical procedures, regarding environmental recovery and control, as well as some adequacy, are put into effect aiming the anticipation of these areas appropriation for public usage. This research investigates the current brownfields/space impediment conditions, characterized by discontinued landfills ruled by the Municipality of São Paulo Town Hall , starting from the 70's decade, analyses the conditioning environmental risks for the after-closing utilization, the public service and local population interests with reference to the the Vila Albertina discontinued landfill, by establishing that it is foreseen, both, the environmental recovery and implantation of parks inside discontinued landfill areas, within the next years throughout a joint action involving public authorities and private entrepreneurs.
