Brownfields

The EPA defines a "brownfield site" as "real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant." A "brownfield" generally refers to a parcel of land that was previously used for industrial purposes and which is contaminated past low concentrations of hazardous chemicals.

A brownfield differs from a superfund site in that information technology is less severely contaminated, and thus less probable to exist cleaned up with federal funds. Estimates of the number of brownfield sites range from 400,000 to over one million. The vast bulk of brownfields are institute in urban industrial areas and tend to be disproportionately located in working form communities and/or communities of colour.

Brownfields are widely recognized as an environmental justice issue due the range of potential hazards associated with the land. When sites remain vacant, toxins nowadays on the land go on to bear on air and water quality, and in plough, human wellness. In add-on to the chemicals that remain afterward an manufacture or business organization vacates the state, what is often a vacant lot tin get a site for the illegal dumping of hazardous wastes. This creates a situation that deters economic development, decreases belongings values, and harms the aesthetic value of a community. Social scientists have suggested that brownfields disrupt the social fabric of a community and negatively impact the maintenance of social networks and community ties.

While some state and federal funds may be allotted to brownfield remediation, local and community groups are oft left to deal with hazardous sites on their own. Redevelopment is difficult due to a variety of bug related to the hazardous chemicals present on the land: belongings owners are reluctant to sell property for fright of what an ecology assessment may uncover; banks may pass up to foreclose on potentially contaminated properties when an possessor defaults, for fear of facing liability for cleanup costs; banks may refuse financing to purchase or develop of potentially contaminated property; and insurance companies may refuse to insure properties they fright may exist contaminated.

Cos Cob: A New Customs Asset From an Former Contaminated Site

Cynde Sears , in Environmental Geochemistry (Second Edition), 2018

2 Background: Cos Cob Power Constitute, Connecticut

The Cos Cob power plant brownfields site is located in the Town of Greenwich, on the banks of the Mianus River in southern Connecticut, ~   35 miles (56.4   km) north of New York City. Fig. 14.1 shows the location of the State of Connecticut; Fig. 14.ii shows the location of Cos Cob inside the state.

Fig. xiv.ane. Location of state of Connecticut, United States.

Fig. 14.2. Location of Cos Cob, Connecticut.

The original power plant (meet Fig. fourteen.3) was synthetic on a 5-acre (0.02   sq   km) site on the banks of the Mianus River to provide high voltage, single-stage alternating electric current electricity for railroad lines that served train lines from Greenwich into New York Urban center. In 1903, New York had banned coal-powered trains from coming into the urban center because of several serious accidents that had resulted from low visibility in tunnels caused past the steam the railroad train engines emitted. To respond to the increased demands, the New Haven Railroad decided to install high-voltage xi,000-volt overhead wires on its tracks from Woodlawn, New York, into Connecticut. The railroad determined that information technology would build its own ability station to generate high-voltage, single-phase alternate current electricity for its railroad lines, which was a major applied science feat for the time.

In 1905, Westinghouse, Church, Kerr & Company began to construct the coal-powered Cos Cob plant on a site on the banks of the Mianus River. Information technology was the first power plant to be built exclusively for a railroad, and information technology was completed and began generating ability in 1907. The plant was a multilevel concrete and metal building, and housed a multifariousness of electrical generation and distribution equipment, including boilers, transformers, circuits, and breakers.

For decades, waste products from the power plant, including fly ash, bottom ash and slag, were deposited along the northern and southern ends of the facility. And then much ash and slag were deposited that the facility virtually doubled in size, from its original 5-acre lot to an area of 9.4 acres (0.04   sq   km); deposits extended to more than than 35   anxiety (10.7   yard) below ground surface throughout the northern and southern ends of the site.

The railroad company operated the plant until 1986; they then closed it and moved to a new generating station nearby. The State Department of Transportation decommissioned the establish in 1987, merely left much of the equipment intact, including boilers, transformers, circuits and circuit breakers.

The Bagnoli-Napoli Brownfield Site in Italy: Before and After the Remediation

Benedetto De Vivo , Annamaria Lima , in Environmental Geochemistry (Second Edition), 2018

7 Natural and Anthropogenic Components of the Pollution

As stated in the introduction, the Bagnoli brownfield site contains metallic elements whose source overlaps a natural component (ascribable to the CF hydrothermal activity connected to the quiescent volcanism) and an anthropogenic i (due to the industrial action). The challenge was demonstrating and separating the contribution of these two components.

Pb isotopes are used to written report environmental pollution because of its relative geochemical immobility and for the wide use of Pb in industrial processes. Moreover, Lead isotopes are not fractionated past natural or industrial processes; Lead isotopic composition in a material remains constant in time and reflects the nature of the source (Ault, Senechal, & Erlebach, 1970).

Pb used in industrial processes is extracted from sulfide ore deposits of different ages and origins. Once released in the environs from industrial activities, this metallic is adsorbed by Fe and Mn oxides, whose formation in plow is fostered by atmospheric agents. Determining the isotopic composition and the chemical composition of soils allows us to separate anthropogenic Lead from natural sources, helping to ascertain the origin and extent of the contribution of anthropogenic sources to pollution.

The utilize of Lead isotopes in this field dates back to the 1960s (Chou & Johnstone, 1965) and it has been employed in numerous studies in European and Mediterranean regions (Maring, Settle, Buat-Meanard, Dulac, & Patterson, 1987; Grousset et al., 1995; Hopper, Ross, Sturges, & Barrie, 1991). Fewer studies have been conducted in Italia and they take never been applied to industrial sites (Magi et al., 1975; Garibaldi, Vanini, & Gilli, 1981; Facchetti et al., 1982; Colombo et al., 1988; Facchetti, 1989; Cochran, Frignani, Salamanca, Bellocci, & Guerzoni, 1998; Monna et al., 1999; Tommasini, Davies, & Elliott, 2000; De Vivo et al., 2001).

At the Bagnoli brownfield site, Tarzia et al. (2002) (as function of his PhD plan with University of Naples Federico II), carried out a study aimed to discriminate anthropogenic from natural pollution sources. For this study PTEs and Lead isotope data from soils, waste materials, scum, and slag samples from the brownfield site were used.

The samples used for isotopic analysis were collected from 20 boreholes during the monitoring activities of Stage I, using a 100   ×   100   m grid. Selected samples were dried in air and sieved to extract the <   2   mm fraction. This fraction was then homogenized, quartered, and sieved once again to extract the <   177   ÎĽm (lxxx   mesh) fraction. After processing, the samples were analyzed every bit follows: (one) Inductively coupled plasma-diminutive emission spectrometry (ICP-AES) to determine major, small-scale and trace elements; (2) X-ray fluorescence (XRF) to determine mineralogy of scum and slag; (iii) Inductively coupled plasma-mass spectrometry (ICP-MS) for Pb isotope analysis. The XRF and part of the Pb analysis were carried out at the USGS laboratories (Reston, Virginia), while the remaining Pb isotope analyses were carried out at the British Geological Survey (Nottingham, United Kingdom).

ICP-AES assay determined concentrations for the post-obit elements: Ag, Al, As, Au, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, Ga, Hg, K, La, Mg, Mn, Mo, Na, Ni, P, Pb, South, Sb, Se, Sr, Te, Th, Ti, TI, U, V, W, Zn.

The Atomic number 82 isotope results showed a linear trend that suggests a mixing betwixt ii cease members, one natural and related to the CF volcanics, and the other anthropogenic. The large overlap of isotopic data does not let a precise quantitative discrimination of the contribution of each component, but information technology is possible to state that the natural component dominates.

Plots of metal concentrations against Lead isotope ratios were extremely useful. For example, Cr values were plant to be distributed along 2 clearly different clusters. One cluster represents the soils of Bagnoli, while the other corresponds to the waste (scum, slag, landfill) textile. For decreasing Cr concentrations, the data seem to converge toward soil values. Similar trends are detected for other elements (Fig. xv.9).

Fig. 15.9. Cr vs Mn (A) and As vs Cd (B) concentrations. Such plots bear witness the convergence of data toward natural values (bold arrows) and propose a human relationship between contamination and scum, slag and landfill materials.

The plots ostend the existence of a contamination characterized by isotopic values very similar to those of the soils (i.eastward., the natural values). Plots of the isotopic ratios (207/204Pb vs 208/204Pb) show two distribution trends that converge toward values typical of the Neapolitan Yellow Tuff (D'Antonio, Tilton, & Civetta, 1995; Fig. 15.10).

Fig. 15.10. Plot of 207Pb/206Pb vs 208Pb/206Lead. The dashed expanse represents the field of isotopic limerick for the NYT (as reported by D'Antonio et al., 1995). The direct arrows underline the general trends of mixing between three potential Pb end members (Tarzia et al., 2002).

Fig. 15.11 shows the plot of Pb isotopic ratios for possible end members, such as gasoline, aerosols (Italian and European), and coal, compared to the ratios recorded in Bagnoli. For Italian gasoline, merely a few data points (gasoline with additives from Mexico and Peru) are consistent with Bagnoli. The same is true for aerosols, with the but exception being an aerosol from Senegal.

Isotopic data from coal imported from the Appalachian Bowl of the eastern Usa are instead consistent with Bagnoli, since this coal was used at Bagnoli as an additive in the smelting furnace during the steel manufacturing process. The raw material (i.eastward., Iron minerals) was imported from Liberia, Canada, Republic of india and other nations; unfortunately, the only isotopic data available in the literature are for Loulo and the Nimba shield Fe formations (Liberia, Eastern Africa), and those are not compatible with Bagnoli data.

Chemical and isotope information clearly show mixing between a major natural component (e.g., reworked subaerial and marine volcanics), and an anthropogenic 1. Hydrothermal fluids associated with the CF agile volcanism, an area where fumaroles and hydrothermal springs are quite abundant, provide significant contribution to the metals nowadays at this site. The natural contamination due to the upwelling of geothermal fluids (enriched in PTEs such equally Every bit, Cu, Pb, and Hg) is confirmed past the high concentrations of PTEs found in the thermal springs (spas) located at the margins of the brownfield site of Bagnoli (e.g., the Terme di Bagnoli, Dazio, the Terme Puteolane, the Stufe di Nerone) and of the nearby island of Ischia (Daniele, 2000; Lima, Daniele, De Vivo, & Sava, 2001; Lima, Cicchella, & Di Francia, 2003). Every bit values at the Stufe di Nerone reach up to 8000   ppb, while at Ischia values are >   1500   ppb.

Isotope values from soils and waste product (e.g., scum, slag) are like, but a large overlap in data does non allow precise discrimination of the natural component from the anthropogenic one. Isotope ratio trends for soils and waste in Bagnoli is partially divergent from the "classic" anthropogenic trend divers by gasoline combustion and aerosol values from other parts of the world. This suggests that for the Bagnoli area, at that place is a local source of contamination, probable from fossil fuel utilize and the emission of industrial fumes. Italian gasoline with additives from Mexico and Republic of peru are partially responsible for contamination, but the major role has surely been played by the large amounts of coal used in the industrial process. All the same, other sources, such as paints, mineral oils, and uncontrolled organic and inorganic sewer waste, for which data are not available, cannot be ruled out as sources for some contaminants.

The presence of a major natural contribution (i.e., hydrothermal fluids) for the metal contamination makes metal remediation of the Bagnoli expanse to a level below local background futile. This determination is further strengthened by the observation that scum and slag proved to be geochemically very stable relative to their metallic contents; leachability tests prove that neither scum nor slag releases metals into soils and groundwater at the pH and local weather condition existing in the regional area.

thirty.ane.4 SuDS in Edinburgh

In 2004, construction projects in Edinburgh's outskirts were dominated past greenfield site development activities. City regeneration projects were predominantly restricted to brownfield sites. Current and proposed edifice projects within the city boundary were the City Centre, the Granton Waterfront, Edinburgh Park, Due south Gyle, and Sighthill. These areas were designated to become commercial or loftier-density residential developments.

Within the city, in that location are designated recreational areas that can be used to drain runoff after SuDS implementation. This process of utilizing recreational space is a less controversial course of SuDS retrofitting. As development and regeneration activities increase, the amount of impermeable surfaces also increases. It follows that there is a pressing need to use SuDS techniques to control runoff by footing infiltration or storage, which has benign impacts on downstream catchments (City of Edinburgh Council, 1999).

Flooding within the metropolis of Edinburgh is mostly acquired by rainfall in the upper river catchment areas, which prevarication exterior the boundaries of the metropolis. Recent flooding has occurred predominantly in the following catchments and localities: River Almond and Gogar Fire; Ferry Burn; South Queensferry; Linn Manufactory Burn down; Complect Burn down and Figgate Burn down; Burdiehouse, Niddrie, and Brunstane Burn (Metropolis of Edinburgh Council, 1999).

INNOVATIVE RESPONSES TO CHALLENGES: REDEVELOPMENT OF COS COB BROWNFIELDS SITE, CONNECTICUT, Usa

Cynde Sears , in Environmental Geochemistry, 2008

4.1.1. Federal funding to support site cess

In 1995, in recognition of the importance of overcoming this barrier to redevelopment, US EPA began to provide funding to states and communities for brownfields site assessments. Communities could receive upwards to $200,000 over a ii-year flow, and could apply the funding to inventory, characterize, appraise, and program for cleanup and redevelopment, and to perform a range of customs involvement activities related to brownfield sites. The incentive worked. From 1995 through mid-2004, more vi,000 brownfields sites were assessed with these funds, and more than two,100 properties were made ready for reuse ( US Function of Management and Budget, 2006). The plan was well-funded in 2005 through 2007, and will likely be extended into the foreseeable future. Many communities have reported that the EPA site cess grants accept "jump started," "catalyzed," or "boosted" their efforts to redevelop brownfields sites.

Support for this initiative has expanded greatly since 1995. In 2001, the Us Congress passed the Small Concern Liability Relief and Brownfields Revitalization Deed (also known as the 2002 Brownfields Constabulary). This act, which updates the Superfund legislation, authorizes The states EPA to provide up to $50 1000000 in grants to states and tribes to institute or heighten programs to assess, cleanup, and redevelop brownfields. Each yr since 2003, EPA has distributed almost $50 meg in brownfields grants to states, territories, and tribal groups.

Long-term Performance of Permeable Reactive Barriers

Peter Niederbacher , Manfred Nahold , in Trace Metals and other Contaminants in the Environment, 2005

A Introduction

Industrial state utilize since the early stages of industrialisation has, in many cases, caused environmental impacts on the soil and groundwater. Nowadays these industrial brownfield sites, which are often situated in well-developed urban areas, are existence reused for new edifice projects. This procedure has been called "brownfìeld recycling". At the former site of a tar manufactory and linoleum production plant in Brunn am Gebirge nearly Vienna, Austria, soil and groundwater contaminations caused mainly by residuals of tar production were detected during the starting phase of structure for a business concern park. To allow the proposed land use without undue delay, a remediation scheme that included an innovative groundwater treatment and protection organisation was adopted.

The organisation pattern is based on the permeable reactive barrier (PRB) concept. It consists of a hydraulic barrier with four openings, each continued to an adsorptive reactor filled with activated carbon (Air-conditioning). The flow through the system is driven past the hydraulic gradient between the contaminated (upstream) surface area and the runoff of the arrangement (downstream) to an artificial groundwater pond, which is connected to the river system. The technical facilities are fully integrated into the business park, which was built at the location. The organisation implementation was financed past a individual investor and supported by funds of the Democracy of Austria.

The start of the European research projection PEREBAR ("Long-Term Performance of Permeable Reactive Barriers Used for the Remediation of Contaminated Groundwater", run into Preface; Niederbacher, 2000 and 2001) in 1999 coincided with the start-up of the Adsorptive Reactor and Bulwark (AR&B) system in Brunn am Gebirge. This was an excellent opportunity to cull the site for closer investigation during the start-upwards phase and first years of functioning of a total-scale PRB system. The investigation was undertaken in cooperation with the consultant group Niederbacher/Mapag who is responsible for system design and monitoring. The monitoring facilities installed in the AR&B system allowed the functioning of a projection calibration PRB to be investigated nether real world conditions. Likewise routine monitoring for the control of hydraulic office and purification efficacy, the investigations performed in the course of the PEREBAR project allowed a detailed study of general conditions which are influencing the long-term behaviour of the AR&B system.

Greenfield Evolution

P. Breathnach , in International Encyclopedia of Human Geography, 2009

Introduction: Defining Greenfield Evolution

The term greenfield development originally referred to economic activities (ordinarily manufacturing plants) which were established on sites which had not previously been developed (except for agronomical purposes). Such sites assorted with and then-called brownfield sites which were, or had been, previously developed for industrial purposes, particularly involving sometime-generation industrial activities, such equally coal mining, heavy industry, and dockland activities. As the term itself suggests, greenfield development in this context generally referred to establishing economic activities either in rural areas or, more typically, on the outskirts of towns and cities.

Over time, the employ of the term was broadened to embrace any business investment by a firm which involves setting up an operation in a new location (whether urban or rural) rather than, for example, expanding or acquiring existing operations. This new activity may involve a net addition to the business firm's productive chapters, or only a relocation of an existing activity from some other site, or sometimes a rationalization of a number of existing activities at dissimilar sites. These unlike possibilities behave with them very different implications in terms of their local, regional, and national economic development impacts.

Analysis of patterns of greenfield evolution bring together 2 important areas of concern in economical geography – industrial location and regional development. Geographers have long been interested in analyzing patterns of industrial location – including the establishment of new industrial plants on greenfield sites – and the factors which influence how these patterns are shaped. Interregional variations in forms and levels of economic development and the processes producing these variations have as well been a major focus of geographical enquiry. The stimulation of greenfield investments in manufacturing (and, increasingly, services) activities in less-developed regions has been an important feature of public policy in most advanced economies, and geographers have made an important contribution in terms of examining the nature, location, and economical impact of such investments.

Solar Parks and Solar Farms

Philip R. Wolfe , in Practical Handbook of Photovoltaics (2nd Edition), 2012

2.ane.iv Location and Land Usage

Another central issue of course is the geographical location itself and the current use of the land. This can impact, in particular, the speed and success of planning consent (equally further discussed in Section 4.i).

Siting solar parks on and so-chosen brownfield sites, such as sometime industrial or armed services estates, quarries, and landfills, tin often enhance the prospects of planning approving. Many regime would consider this a good way of remediating such land.

Using agricultural state is more than contentious. Solar parks do not fully cover the country, and so there is often considerable space between the solar arrays, which tin can go on to be used for other purposes, provided these exercise not shade or dirty the arrays. The grazing of sheep in solar parks is a good complementary application, equally that will forbid the growth of vegetation that could create shadows over time. However, many agricultural activities—intensive farming in particular—get impossible in solar farms. To prevent unnecessary conflict for state use between energy and food, therefore, solar parks should generally not exist sited on prime number agricultural country.

Having found a suitable site, information technology'south then time to design the arrangement. Many factors are generic to PV systems in general and are therefore covered elsewhere in this book. I shall bargain here with the specifics of large-scale solar parks.

Operationalizing NBS in low- and middle-income countries: Redefining and "greening" project development

Alex Mauroner , ... Sujith Sourab Guntoju , in Nature-based Solutions and Water Security, 2021

Understanding the office of natural majuscule

In NBS, the potential of natural processes is utilized to address a detail issue or prepare of problems. Before developing whatever NBS intervention, a thorough understanding of the natural capital and the natural processes is required. A preliminary step is developing an inventory of natural capital, see, for example, Cassin (2021).

Knowing the capacity of the existing natural resources and their respective vulnerabilities is essential to designing a sustainable solution. Equally of import is determining whether multiple NBS projects within a purlieus could take competing or conflicting functions. For example, Vocal et al. (2019) suggest that the apply of NBS for contaminated land remediation or redevelopment of brownfield sites may depend on the choices made at other brownfield sites in the same city or metropolitan area. If a given brownfield site is converted into a greenspace for public access, it may discourage the same choice for other sites. Similarly, conversion of brownfield sites into industrial heritage parks may depend on whether the metropolitan surface area has other industrial heritage parks and whether the nation has other facilities of like nature (if originating from the same industrial sector and maintained with similar historical features). They too outline that native or imported plant species, or even genetically modified species, tin be used to address contaminated land issues through a process known as phytoremediation ( Song et al., 2019). In gild to go on with an effective phytoremediation, it is essential to have an inventory of the potential plants.

NBS interventions comprehend a wide spectrum in terms of form and part; however, they are non a necessary or appropriate solution to every problem. The ceremoniousness, design, and cobenefits of dark-green solutions are largely context-specific (Kapos et al., 2019); their functions are interwoven into a web of overlapping systems. Larger scale assessments, such as landscape or catchment-level, are necessary to empathize the complex dynamics of (and potential for) green solutions.

Environmental Justice and Interventions to Forbid Environmental Injustice in the United States

A. Lubitow , D. Faber , in Encyclopedia of Environmental Health, 2011

Brownfields

The The states EPA defines brownfields as 'real holding, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant.' A brownfield generally refers to a parcel of country that was previously used for industrial purposes and that is contaminated by low concentrations of hazardous chemicals.

A brownfield differs from a Superfund site in that it is less severely contaminated and will non exist cleaned up with federal funds. Estimates of the number of brownfield sites range from 400  000 to over i million in the United states. The vast majority of brownfields are found in urban industrial areas and tends to exist disproportionately located in working-form communities or communities of color.

Brownfields have become widely recognized as an ecology justice upshot due to the range of potential hazards associated with the land. To begin, when the sites remain vacant, the toxins nowadays on the land go on to impact air and water quality, and in turn, human wellness. In addition to the chemicals that remain after an industry or business organisation vacates the land, what is ofttimes a vacant lot tin can become a site for the illegal dumping of hazardous wastes. The sites are besides problematic in that they deter economic development, decrease property values of residents living nearby, and damage the aesthetic value of a community. Social scientists have suggested that brownfields disrupt the social textile of a community and negatively impact the maintenance of social networks and customs ties.

Although some state and federal funds may exist allotted to brownfield remediation, local and community groups are often left to deal with chancy sites on their own. Redevelopment is difficult due to a diverseness of issues related to the hazardous chemicals present on the land: belongings owners may refuse to sell property for fearfulness of what an environmental assessment would uncover; banks may turn down to forestall on potentially contaminated properties when an owner defaults for fear of facing liability for cleanup costs; banks may as well reject to provide financing for purchase or development of potentially contaminated property; and insurance companies may refuse to insure backdrop they retrieve might be contaminated.

Brownfield redevelopment is a circuitous issue for the ecology justice motion. A lack of political and economic resources in communities where brownfields are most common frequently prevents or delays the reuse and revitalization of brownfield sites. The empty lots where brownfields are sited contribute to the deterioration of customs cohesion and betrayal inhabitants to a variety of unhealthy chemicals, pollutants, and other toxins.
