Plasma Spectroscopic Techniques Applied to Biological and Environmental Matrices

The purpose of this research was to apply the use of direct ablation plasma spectroscopic techniques, including spark-induced breakdown spectroscopy (SIBS) and laser-induced breakdown spectroscopy (LIBS), to a variety of environmental matrices. These were applied to two different analytical problems. SIBS instrumentation was adapted in order to develop a fieldable monitor for the measurement of carbon in soil. SIBS spectra in the 200 nm to 400 nm region of several soils were collected, and the neutral carbon line (247.85 nm) was compared to total carbon concentration determined by standard dry combustion analysis. Additionally, Fe and Si were evaluated in a multivariate model in order to determine their impacts on the model's predictive power for total carbon concentrations. The results indicate that SIBS is a viable method to quantify total carbon levels in soils; obtaining a good correlation between measured and predicated carbon in soils. These results indicate that multivariate analysis can be used to construct a calibration model for SIBS soil spectra, and SIBS is a promising method for the determination of total soil carbon. SIBS was also applied to the study of biological warfare agent simulants. Elemental compositions (determined independently) of bioaerosol samples were compared to the SIBS atomic (Ca, Al, Fe and Si) and molecular (CN, N2 and OH) emission signals. Results indicate a linear relationship between the temporally integrated emission strength and the concentration of the associated element. Finally, LIBS signals of hematite were analyzed under low pressures of pure CO2 and compared with signals acquired with a mixture of CO2, N2 and Ar, which is representative of the Martian atmosphere. This research was in response to the potential use of LIBS instrumentation on the Martian surface and to the challenges associated with these measurements. Changes in Ca, Fe and Al lineshapes observed in the LIBS spectra at different gas compositions and pressures were studied. It was observed that the size of the plasma formed on the hematite changed in a non-linear way as a function of decreasing pressure in a CO2 atmosphere and a simulated Martian atmosphere.

Oil and Gas Environmental Documentation Guidance Based on Existing Environmental Assessment Documentation

The hard push for domestic oil and gas production suggests a developing divergence from environmentally sound practices. As states feel the pressure to match energy growth to national need, adequate consideration for the surrounding environment should continue to be a high priority. Through an analyses of twelve environmental assessment documents, recommendations for an oil and gas specific environmental assessment documentation guidance has been created. Guidance recommendations for the affected environment, mitigation options, alternatives, public comment process and the overall approach to an environmental assessment document is outlined within this capstone.

Genetically Engineered Crops: A Study of Major Environmental Implications and U.S. Policy

The adoption of genetically modified crops is becoming evermore common in United States agriculture. However, this relatively new technology carries a negative stigma and perceived risks that have resulted commonly in public disapproval. In the United States, bioengineered crops are highly regulated. The significance of environmental benefits such as decreased chemical impact, increased soil conservation, heightened carbon sequestration, decreased energy demands, and reduced air emissions, are important enough to warrant a revision to U.S. policy. The U.S. policy structure needs to be simplified and made more efficient to better facilitate the speed with which new GE products can, and should, be developed while still providing adequate mitigation of potential environmental risks such as species invasiveness and impacts on non-target species.

Coastal Erosion--Causes, Erosion Control Methods, Economic and Environmental Impacts, and Best Management Practices

Coastal erosion is an important and constant issue facing coastal areas all over the world today. The rate of coastal development over the years has increased, in turn requiring that action be taken to protect structures from the threat of erosion. A review of the causes of coastal erosion and the methods implemented to control it was conducted in order to determine the best course of action in response to coastal erosion issues. The potential positive and negative economic and environmental impacts are key concerns in determining whether or not to restore an eroding beach and which erosion control method(s) to implement. Results focus on providing a comparison of these concerns as well as recommendations for addressing coastal erosion issues.

Affordable Environmental Cleanup Actions at Abandoned Hard Rock Mine Sites

Abandoned mine land cleanups are limited by restrictive regulations, inconsistent and unavailable funds, and a lack of adequate protections for stakeholders attempting to improve site conditions. This study evaluated examples of two cleanup mechanisms: an EPA-lead CERCLA cleanup and a state-lead, stakeholder-funded approach. The case studies showed that CERCLA provides the most comprehensive funding mechanism for abandoned mine cleanups while offering very little flexibility. State-lead programs allow for more flexibility, yet states are bound by federal laws and are hampered by lack of funding. Case analysis determined that any new approach should provide adequate funding, be flexible in its cleanup criteria, and minimize liability for those undertaking cleanups. It must also protect human health and promote natural ecological recovery.

A Case Study of the Economic and Environmental Impacts from a Bio-fuel Facility (Southwest Georgia Ethanol, LLC) on the Surrounding Communities, Southwest Georgia

Bio-fuels such as ethanol provide an extraordinary opportunity to address our dependency on foreign oil. This case study examines the economic and environmental impacts associated with constructing and operating a dry mill ethanol manufacturing facility in a Southwest Georgia town and surrounding communities. The case study found that the plant had little impact on air quality, water quality, and habitat fragmentation. However, economic results showed the plant produced $1.5 million in tax revenues, and 86 jobs. Ethanol producers and communities must consider both the economic and environmental impacts on a local community when searching or attracting a bio-fuels plant. Likewise, communities should be aware of these challenges when attracting ethanol production plants.

The Environmental Costs of Automobile-Centric Transportation Planning

Since the passage of the Federal-Aid Highway Act of 1956, the automobile has become the primary form of transportation on the Mississippi Gulf Coast. As the rate of motor vehicle use continues to rise faster than population growth, the benefits of the current transportation system are coming at a price that rivals annual household expenditures for housing. Furthermore, the automobile-centric transportation system incurs environmental costs. Carbon dioxide emissions, motor fuel use, health care costs for chronic illness, and the loss and impairment of natural resources due to sprawling development, continue to escalate. This project analyzes the environmental costs associated with automobile-centric planning for the urbanized area of the Mississippi Gulf Coast and compares these costs to those of alternative transportation modes.

A Proposed Environmental Policy for the Evaluation of State Funded Projects for use by the Utah Department of Transportation

Utah lacks a NEPA-equivalent environmental law for state funded projects. UDOT policies provide guidance on complying with NEPA but not on environmental reviews of state funded transportation projects. These projects are either not evaluated for impacts or are evaluated without a formal process, resulting in inconsistent and inadequate consideration of resources and project alternatives, with limited public involvement. This capstone provides a standard policy for UDOT. The policy incorporates elements from other state DOT polices and is based on federal NEPA, CEQ regulations, FHWA technical guidance, and existing UDOT procedures. Implementation will ensure consideration of project impacts to resources, analysis of project alternatives, encourage meaningful public involvement, and improve interagency coordination.

Improving urban park design: A comparative and analytical study addressing resources available and components necessary to improve the environmental and economic sustainability of urban parks

Urban parks have long been valued for the environmental, social, and economic benefits they provide. Increasingly, parks are also being recognized as features important for sustainable city design. This Capstone Project will identify, compare, analyze, and discuss means for designing sustainable urban parks. Recommendations for designing sustainable urban parks, based on project results, include: 1) ensure park features will support high levels of human activity; 2) use gravel to construct park trails; 3) purchase playground structures made of recycled materials; 4) plant a high number of perennials in flowerbeds and other vegetated areas; 5) plant climate-appropriate plants in vegetated areas; 6) ensure parks have high levels of plant diversity; and 7) develop future studies further exploring sustainable park design.

Utilization of ADR Concepts to Bridge the Gap Between the Extractive Industry and Environmental Interests: An Anticipatory Cooperative Effort (ACE)

The extractive industry, more than any other sector of the economy, often finds itself mired in conflicts with various environmental and community interests. As traditional legal avenues of resolution gave way to the collaborative ideas of alternative dispute resolution, the outcomes, especially the relational outcomes, were less than desirable. This capstone project proposes that an Anticipatory Cooperative Effort (ACE) can help to bridge the gap between industry and environmental interests by encouraging a pro-active and pre-emptive engagement. The point of the ACE concept is not that it defines a new set of principles so much as it repositions where established ADR principles are entertained.

Remaking Movie Making: The Environmental Impacts of the Film Industry in Southern California

The film and television industry is integral to the economics and culture of the Southern California region. It is also a major contributing factor to the environmental problems in the region. Currently the Motion Picture, Television, and Commercial Industries Act of 1984 is the only regulation written specifically for the entertainment industry. This regulation was created with the purpose of streamlining the film permitting process to prevent run-away production, taking production out of state, and encourage growth. A change in this regulation is needed since studios routinely fail to meet environmental standards or work towards improvement during on-location filming. Amendments to this regulation requiring permits to contain environmental conditions would improve environmental conditions and stay true to the original purpose of the act.

Surface and Groundwater Environmental Policy Compliance at the Adams County Regional Park and Fairgrounds

The Adams County Regional Park and Fairgrounds must comply with environmental policies related to surface water and groundwater protection. This paper assesses various methods which have proven to be effective in the reduction of nutrients and other contaminants found in surface and groundwater at comparable livestock-based venues. Data was gathered from other facilities in order to identify specific compliance alternatives and evaluate management options. Empirical research, coupled with GIS mapping technology yielded explicit water quality management recommendations for the Adams County Regional Park and Fairgrounds. The outcome of this research and mapping exercise include twelve management recommendations and two site-specific locations for structural BMPs designed to better control water pollution at the Adams County Regional Park and Fairgrounds.

Environmental Information Access as a Security Risk

The United Sates was founded on the principles of freedom. Events in recent history have threatened the freedoms we as individuals enjoy. Notably, changes to government legislation and policies regarding access to environmentally sensitive information following September 11, 2001, are troubling. The government has struggled with a difficult balancing act. The public has the right of access to information, yet, information some view as sensitive or dangerous must be kept out of the hands of terrorists. This project examines and discusses the information access debate within the United States and how to best provide the public environmentally sensitive information.

Guide to Writing a Programmatic Resource Management Plan/ Environmental Impact Statement for the Bureau of Land Management

This guide is written for Booz Allen Hamilton (BAH) employees assigned to the Public Lands team who may have some National Environmental Policy Act (NEPA) knowledge, possibly have experience with writing Environmental Impact Statements (EIS), and with little or no experience writing programmatic EIS documents. The guide contains information encompassing the preparation of a complete Resource Management Plan/Environmental Impact Statement (RMP/EIS) for the Bureau of Land Management. The RMP/EIS is a programmatic NEPA document which has many differences and nuances distinct from a typical project type EIS. This guide provides the information necessary for a BAH Public Lands team member to understand the project process and the RMP/EIS document to successfully maneuver through the entire project from beginning to end.
